Implementation Of Cloud Computing Inside College Campus Information Technology Essay

Implementation Of Cloud Computing Inside College Campus Information Technology Essay CLOUD COMPUTING can represent a unique opportunity to  reduce the costs associated with infrastructure  and can help to accomplish achieve ever greater levels of efficiencies. With Cloud Computing users can access database resources via the Internet from anywhere, for as long as they need, without worrying about any maintenance or management of actual resources. Besides, databases in cloud are very dynamic and scalable.In this paper we discuss on implementing a cloud computing platform that enables Software as a Service (SaaS) to provide a closed box execution environment that guarantees remote execution of programs in a Local Area Network.Inside a college,students can make use of the cloud resources available online, through a simple web interface. INTRODUCTION: Cloud computing provides the facility to access shared resources and common infrastructure,offering services on demand over the network to perform operations that meet changing business needs. The location of physical resources and devices being accessed are typically not known to the end user. It also provides facilities for users to develop, deploy and manage their applications on the cloud, which entails virtualization of resources that maintains and manages itself. DEFINITION: A cloud is a pool of virtualized computer resources. A cloud can: Host a variety of different workloads, including batch-style back-end jobs and interactive, user-facing applications Allow workloads to be deployed and scaled-out quickly through the rapid provisioning of virtual machines or physical machines Support redundant, self-recovering, highly scalable programming models that allow workloads to recover from many unavoidable hardware/software failures Monitor resource use in real time to enable rebalancing of allocations when needed BENEFITS OF CLOUD COMPUTING: CLOUD COMPUTING can represent a unique opportunity to  reduce the costs associated with infrastructure  and can help to accomplish achieve ever greater levels of importantefficiencies. These efficiencies can include not only cost reduction, but also improved access to resources and essential data. The determination as to whether cloud computing services are a good match for your particular business will of course depend the  size of your enterprise, its general needs and your overall sales goals.   Cloud computing, typically entails: High scalability Cloud environments enable servicing of business requirements for larger audiences,through high scalability. Agility The cloud works in the distributed mode environment. It shares resources among users and tasks, while improving efficiency and agility (responsiveness). High availability and reliability Availability of servers is high and more reliable as the chances of infrastructure failure are minimal. Multi-sharing With the cloud working in a distributed and shared mode, multiple users and applications can work more efficiently with cost reductions by sharing common infrastructure. Virtual service Virtual servers seek to encapsulate the server software away from the hardware This includes the OS, the applications, and the storage for that server.Servers end up as mere files stored on a physical box, or in enterprise storage.A virtual server can be serviced by one or more hosts, and one host may house more than one virtual server. Virtual servers can be scaled out easily.If the administrators find that the resources supporting a virtual server are being taxed too much, they can adjust the amount of resources allocated to that virtual server.Server templates can be created in a virtual environment to be used to create multiple, identical virtual servers.Virtual servers themselves can be migrated from host to host almost at will. NEED FOR CLOUD: As an end user, cloud computing lets you run software applications and access data from any place and time, and from any computer; without the need to ever install, upgrade, troubleshoot software applications physically on a local desktop or server. This is one of the most important elements of cloud computing, and why it has become so popular today. In a sense, cloud computing outsources the technical hassles to someone else. It could bring hardware costs down. Cloud computing systems would reduce the need for advanced hardware on the client side You wouldnt need a large hard drive because youd store all your information on a remote computer. Cloud computing gives the option of storing data on someone elses hardware, removing the need for physical space on the front end. CLOUD COMPUTING CHARACTERISTICS: Because cloud computing is related to a number of other technologies, it is best defined by the presence of a number of characteristics. These represent ideals that people want for the applications that run on the cloud: Incremental Scalability: Cloud environments allow users to access additional compute resources on-demand in response to increased application loads. Agility: As a shared resource, the cloud provides flexible, automated management to distribute the computing resources among the clouds users. Reliability and Fault-Tolerance:Cloud environments take advantage of the built-in redundancy of the large numbers of servers that make them up by enabling high levels of availability and reliability for applications that can take advantage of this. Service-oriented: The cloud is a natural home for service-oriented applications, which need a way to easily scale as services get incorporated into other applications. Utility-based: Users only pay for the services they use, either by subscription or transaction-based models. Shared: By enabling IT resources to be consolidated, multiple users share a common infrastructure, allowing costs to be more effectively managed without sacrificing the security of each users data. SLA-driven: Clouds are managed dynamically based on service-level agreements that define policies like delivery parameters, costs, and other factors. APIs: Because clouds virtualize resources as a service they must have an application programming interface (API). TYPES OF CLOUD: Public Cloud A public cloud is one based on the standard cloud computing model, in which a service provider makes resources, such as applications and storage, available to the general public over the Internet. Public cloud services may be free or offered on a pay-per-usage model. The main benefits of using a public cloud service are: Easy and inexpensive set-up because hardware, application and bandwidth costs are covered by the provider. Scalability to meet needs. No wasted resources because you pay for what you use. The term public cloud arose to differentiate between the standard model and the private cloud, which is a proprietary network or data center that uses cloud computing technologies, such a virtualization. A private cloud is managed by the organization it serves. A third model, the hybrid cloud, is maintained by both internal and external providers. Examples of public clouds include Amazon Elastic Compute Cloud (EC2), IBMs Blue Cloud, Sun Cloud, Google AppEngine and Windows Azure Services Platform. Hybrid cloud A hybrid cloud is a cloud computing environment in which an organization provides and manages some resources in-house and has others provided externally. Although cloud computing is often said to be the future of the industry, the hybrid model is more prevalent for a number of reasons. Large enterprises often already have substantial investments in the infrastructure required to provide resources in-house. Furthermore, many organizations would prefer to keep sensitive data under their own control to ensure security. Private cloud This cloud computing environment resides within the boundaries of an organization and is used exclusively for the organizations benefits. These are also called internal clouds. They are built primarily by IT departments within enterprises who seek to optimize utilization of infrastructure resources within the enterprise by provisioning the infrastructure with applications using the concepts of grid and virtualization. Advantages They improve average server utilization, allow usage of low-cost servers and hardware while providing higher efficiencies; thus reducing the costs that a greater number of servers would otherwise entail High levels of automation, reducing operations costs and administrative overheads Common Services. Some products offer Internet-based services-such as storage, middleware, collaboration, and database capabilities-directly to users. SaaS. Software-as-a-service products provide a complete, turnkey application-including complex programs such as those for CRM or enterprise-resource management-via the Internet. PaaS. Platform-as-a-service products offer a full or partial development environment that users can access and utilize online, even in collaboration with others. IaaS. Infrastructure-as-a-service products deliver a full computer infrastructure via the Internet. CLOUD WITHIN CAMPUS: When the concept of cloud computing is applied to  web hosting, the result can be a technology that lets users scale resources on the fly, and make  changes according to usage and the particular needs  of the enterprise in real time. Thus, as your traffic fluctuates, the  hosting package  can be adjusted to ensure maximum efficiency and minimum waste. This flexibility allows  businesses  to reduce overhead by only investing in the hosting power they actually need, without incurring downtime or overage charges by driving servers beyond capacity.Instead of getting individual cluster for each and every deparment in our college ,We propose that cloud power can be utilised according to their need by hosting the service in local LAN of college SPECIFICATION: TYPE OF CLOUD: PRIVATE CLOUD Private cloud is implemented within college campus thereby enabling students to Execute complex jobs inside college. Reduce the cost of getting higher-end machines. Avoid wastage of resources through sharing of computing resources. Provide transparency to users. SERVICES PROVIDED: SaaS (Software as a Service) Our web interface application is hosted as a service provided to students belonging to various departments inside college. WORKING OF COMPONENTS: Figure : PHASES: Program submission. Upload program to database server. Processing inside cloud. Return result to client browser. PROGRAM SUBMISSION(FRONT END): The student can submit complex programs like MPI from anywhere inside the local area network through the browser.The programs are entered through the HTML front end on the client browser as shown in the screen shot below UPLOAD PROGRAM TO DATABASE SERVER: Tomcat can be used to implement a java servlet that uploads the program based on user input..Tomcat serves as a back-end which handles requests passed to it from a general purpose web server such as Apache. PROCESSING INSIDE CLOUD: The uploaded program is shared among the nodes.On the back end of the system are the various computers, servers and data storage systems that create the cloud of computing services. The MPI specification allows users to create portable libraries that can take advantage of multiple processors to provide high performance. An increasing number of implementations covering most common platforms are becoming available.MPI is well-suited to a range of environments and can function using multiple processors in a single high-performance computer as well as across a network of lower-powered machines. For complex programs like MPI programs, once the user submits the job, the user will be prompted to enter the number of nodes required by the user for the computation. Thus the user is given the priviledge to choose the number of nodes After job submission, the agent, starts running automatically.It is the component running on the worker nodes. Initially, it has to determine the local system parameters that are essential for job selection and execution.These are the installed memory, the CPU architecture, the availability of some runtime environments and the operating system. It starts the working loop with a query to the server for a job.If the server responds with the copy of the file to be executed, the agent downloads the specified files. The agent starts the job with low operating system process priority and waits for its completion.During the execution,it periodically contacts the server to submit the heartbeat. When the job is finished without any error, all result files and the standard/error out data are uploaded to the server. If all the files are transferred successfully, a final commit is sent to the server.Then and only then, the job is accepted as successfully done and the agent proceeds by waiting for the next job from the server. RETURN RESULT TO CLIENT BROWSER: The computed results are sent back to the client browser. Screenshot: IMPLEMENTATION DETAILS:    Programming language Used: Java    Web Server Used: Apache-tomcat 5.5    Automation of execution is done using: Shell script    Web interface Request Handler: Servlet      Front end: HTML    Database Connector: libmysql-java (jdbc driver for mysql)    Back-end: Mysql 5.0.51a-24 ADVANTAGES: Reduced Cost: Each department need not invest in buying separate servers.The cloud technology will supplement clusters at each department with a single powerful server for all purposes. Increased Storage Sutdents can store more data than on private computer systems.Thus individual computers need not be high-end powerful machines. Highly Automated  The work of compilation and execution will be completely automated. Flexibility Cloud computing offers much more flexibility than past computing methods because a number of services are provided to the user just with a machine and a browser. More Mobility   Students can access server resources wherever they are, rather than having to remain at their desks. CONCLUSION: Cloud computing is the big wave in computing. It has many benefits, such as better hardware management, since all the computers are the same and run the same hardware. It also provides for  better and easier management of data. Thus implementing cloud within a college campus will definitely help in all means.

What Is Demorphin and How Does It Work?

Dermorphin By Kimberly French They are about two to three inches long, bask in the sun by day and track down insects by night. They walk rather than hopping and are native to the dry prairie of Argentina, Brazil, Bolivia, and Paraguay. Known scientifically as phyllomedusa sauvagii, the waxy monkey leaf frog or painted belly leaf frog is often kept as a pet and although these frogs have a careful, calm demeanor, they produce a substance called dermorphin, which is a painkiller 40 times the strength of morphine, and has been responsible for a rash of recent positive drug tests in Quarter Horse and lower-level Thoroughbred races.The waxy monkey leaf frog and its secretion have enough notoriety to be mentioned in a Paul Simon song, Senorita With A Necklace of Tears. â€Å"A frog in South America whose venom is the cure for all the suffering mankind must endure,† he sang. â€Å"More powerful than morphine and soothing as the rain. A frog in South American has the antidote for pain . † As mentioned earlier, dermorphin is extremely potent but does not seem to be as addictive as morphine and is classified by Racing Commissioners International as a Class One drug. It has no therapeutic value whatsoever. Craig W.Stevens, a professor of pharmacology at Oklahoma State University who has studied dermorphin, told the New York Times on June 19 the substance makes animals â€Å"hyper. † â€Å"For a racehorse it would be beneficial,† he said. â€Å"The animal wouldn’t feel pain and it would have feelings of excitation and euphoria. † Located in Denver, Colorado, Industrial Laboratories was the first lab to definitively ascertain dermorphin in postrace testing after clients passed along information from racetrack workers that the frog secretion was being used and some materials confiscated on the backstretch were actually demorphin. We identified dermorphin,† Petra Hartmann, director of direct testing services for Industrial Laborat ories told the New York Times. â€Å"We knew it was out there. There is no resting in this business. You are always chasing something trying to determine what’s rumor, what’s real. † In Hartmann’s opinion dermorphin use is not all over the backside. â€Å"The vast majority of horsemen would never subject their horse to this kind of chemical experimentation,† she said. â€Å"This is a tough issue,† Ed Martin, president of Racing Commissioners International told the New York Times. It’s a cat and mouse game. As soon as you call out dermorphin, they will try something else. That is the daily battle that goes on. † To date more than 30 horses from three states, Oklahoma, New Mexico and Louisiana, have tested positive for the drug. On July 31, the Louisiana State Racing Commission will meet and discuss pending dermorphin cases against nine trainers. These include Quarter Horse trainers Alonzo Loya, Gonzalo Gonzales, Alvin Smith, Jr. , Darell Soileau, Steve Garrison and Thoroughbred trainers Keith Charles, Kyi Lormand and Anthony Agilar.Also on the list is prominent Quarter Horse trainer Heath Taylor, who won the 2008 All American Futurity with the sport’s leading money earner Stoli’s Winner. â€Å"This whole thing has really taken us by surprise,† Charles Gardiner III, executive director of the Louisiana Racing Commission told the New York Times. â€Å"It couldn’t have come at a worse time. We’re fighting back federal intervention. We’re under attack and losing our fan base. Fans believe that the sport is dirty, that there is cheating. And here we have an obvious attempt to cheat. I’m sure there are more positives across the country.It’s not unusual that something isn’t being detected. † â€Å"We hear about some pretty exotic stuff,† Dr. Steven Barker, who directs the testing laboratory at Louisiana State  University, told the New Yo rk Times. â€Å"Frog juice — this is exotic. † Barker also told the Times 15 horses had tested positive in Oklahoma. On May 25, eight of the 25 qualifying victors for the Grade I Ruidoso Futurity at Ruidoso Downs in New Mexico, tested positive for dermorphin, a third place trial finisher also tested positive for the same drug. Two of the winning horses also tested positive for the anabolic steroid stanozolol.The trainers in question include Carl Draper and Carlos Sedillo, who at this time are in the top 10 Quarter Horse trainers in the U. S. in money won, two-time All American Futurity winner John H. Bassett, and J. Heath Reed, whose family has figured prominently in the sport. Two of the horses conditioned by Draper are co-owned by Lola Willis, wife of the New Mexico Racing Commissioner Ray Willis. Willis has been a Quarter horse owner and breeder for nearly three decades and was a member of the New Mexico Racing Commission’s Medication Committee for four years .None of the cases have been prosecuted and no charges filed as the trainers all requested split sample testing and are waiting on the results. Kentucky joined the short list of states that have begun to test for dermorphin and no traces of the drug were found in the system of any of the participants in this year’s Kentucky Derby and Kentucky Oaks. Five of the Derby horses were tested and four Oaks fillies. The test was recently developed by Rick Sams, director of the HFL Sports Lab in Lexington and comes out shortly after the Bluegrass State became the first in the nation to ban the use of Lasix or Salix on raceday. We have not received any intelligence suggesting it has been or is being used in Kentucky,† Dr. Mary Scollay, the equine medical director for the Kentucky Horse Racing Commission. â€Å"However, the detection of dermorphin in other racing jurisdictions post-race samples means that Kentucky needs to be testing for it. † On June 19 the Racing Medicatio n and Testing Consortium sent a notice to state racing regulators to be on the seeking out this drug which it called a â€Å"threat to racing integrity† and also explained dermorphin can be produced synthetically. There’s a lot out there and that would be an awful lot of frogs that would have to be squeezed,† Barker told the New York Times. â€Å"There are a lot of unemployed chemists out there. † To date, there have been no positives in Standardbred or higher end Thoroughbred races. â€Å"It’s kind of like the rules and regulations that apply to driving in different states,† Martin said. â€Å"People know they aren’t supposed to drive drunk or speed, but there are always people that don’t follow the rules. Racing is no different. The cheaters always find a way to cheat or come up with some new drug, but they almost always get caught in the end. † 2 3 4 5

Macbeth’ explores ambition and its consequences Essay

‘Macbeth’ explores ambition and its consequences and I am going to show how he successfully portrays this exploration and where in the play examples of this can be found. In scene three of act one, the witches for the second time in the play are seen. This time they are bragging about their unnatural actions and their powers over the human world. Macbeth and Banquo appear on what Macbeth describes as an unusually, â€Å"†¦foul and fair day.† A foul day would be commenting on the weather but a fair day since they have just been triumphant in a defeat in battle. This description of the day by Macbeth could also mean something else too. It could also represent what is about to happen as well. Fair prophecies are to be told soon, but at the same time they may turn out to be foul. When Macbeth and Banquo confront the witches, they are unsure of what or who they are. Unsure of whether they are mortal or immortal due to the things they are saying and how they appear since they have beards like men. This can be seen when Banquo says, â€Å"†¦What are these,/ So withered, and so wild in their attire,/ That not look like th’ inhabitants o’ th’ earth,/ And yet on’t? Live you, or are you aught/ That man may question? You seem to understand/ By each at once her choppy finger laying/ Upon her skinny lips. You should be women,/ And yet your beards forbid me to interpret/ That you are so.† Then each of the witches hail Macbeth in three different ways. The first is Thane of Glamis. The second witch, Thane of Cawdor. The third witch hails Macbeth and speaks of him as King of Scotland thereafter. Banquo then questions the witches as to what they have to say to him. The first two witches build up to the third witch’s comment that Banquo’s descendants will be kings. After this, Macbeth begins to question the witches for more information as to how these prophesies are to come true and how they know this information. All of a sudden the witches vanish into thin air leaving Banquo and Macbeth to talk about what has just happened and what has been said. Ross and Angus (two of Macbeth’s men) arrive and tell Macbeth of his elevation to Thane of Cawdor, and that the former thane is to be executed for treason. Macbeth and Banquo are in disbelief after being told this since what the witches have told them is really happening. Macbeth is now intent in believing he is to be king due to this occurrence of him becoming Thane of Cawdor. Banquo warns Macbeth that evil is at work even though such good things are being predicted and happening. Banquo is sure there is something sinister behind it all. Macbeth doesn’t want to hear what Banquo is telling him and begins to imagine what King of Scotland would mean for him. Macbeth and Banquo decide to let future take care of itself and agree to discuss this matter at a more convenient time. It is already clear that the two men aren’t in agreement about the situation. Macbeth believes what the witches have told them, since part of what they have already said has come true. Banquo on the other hand is doubtful about what is happening and believes something evil and sinister is happening. Banquo is thinking logically and being very conscious about the current situation. Already ambition and temptation is effecting Macbeth’s actions and thoughts. Doubtfulness and a disagreement in opinion is the only thing challenging their relationship so far but it could get a lot worse. At this point the reader may feel that Banquo is trying to tell Macbeth to not read too deeply into these prophecies told by the witches since they are believed to be evil by him. But on the other hand Banquo may be regarded as jealous towards Macbeth about his good fortunes that are occurring. I think Banquo being regarded as jealous, is thought of more by Macbeth rather than the reader. Macbeth may see Banquo as a threat since his descendants may challenge Macbeth’s position in years to come when he believes he shall be king of Scotland. Macbeth’s ambition within this scene has not yet caused consequences but may do in later scenes to come. When Macbeth enters and Lady Macbeth explains to him what her plans are of killing the king Macbeth does not appear as enthusiastic about the idea and is hesitant. He immediately explains that Duncan will be departing next day. But Lady Macbeth simply says that he shall not see tomorrow and to leave the plans to her. It is understandable for Macbeth not to be all that enthusiastic about the idea of killing the king due to many aspects. These aspects include, Duncan being a relative of Macbeth’s, the potential of being caught, and also a matter of killing someone just to steal a title which belongs to an ally of his. Ambition from Lady Macbeth seems to be a threat towards Macbeth. Her violent, blistering soliloquies in act one, scene five, testify to her strength of will, which completely eclipses that of her husband. The witches are the cause of Lady Macbeth’s actions and ideas. Their prophecies have so far influenced both Macbeth and Lady Macbeth, although Lady Macbeth considerably more so at this point within the play. In scene six Duncan arrives at Macbeth’s castle and is greeted warmly by Lady Macbeth. A very false greeting since the thoughts and ideas running through her mind are far more different than what she is expressing to Duncan in greeting him. This is false sense of security from Lady Macbeth towards Duncan. Ambition is feeding this false sense of security from Lady Macbeth towards Duncan since this is part of her plan to kill the king. Scene seven begins with Macbeth debating to himself the options he has in murdering or not murdering Duncan. He says that the deed would be easy if he could be certain that it would not set in motion a series of terrible consequences. He then considers the reasons why he ought not to kill Duncan. The reasons include: Macbeth is Duncan’s kinsman, subject and host. For someone to be related to and host someone else, then murder them is seen upon as inconceivable. He then comes to the decision to not kill Duncan since the only thing to ‘drive’ his actions of killing the king would be his ambition, which he sees as an unreliable guide. Lady Macbeth is now expressing outrage towards Macbeth and trying to gain sympathy from him towards her since she has just told him that he is not providing her with enough love just because he won’t kill Duncan. This is a very desperate resort that further expresses Lady Macbeth’s character towards the audience. Ambition is driving her evil actions. As Macbeth begins to waver after Lady Macbeth’s insults towards him, she then explains her plan. Immediately after she has explained her plan, Macbeth is surprised by her well thought out plan and her boldness/attitude. He then decides to proceed with the murder. Lady Macbeth’s attitude and ambition is influencing Macbeth to such an extent as to change his feelings and ideas towards the subject. This emphasises the power of ambition expressed from one person towards another. The witches’ prophecises and Lady Macbeth’s ambition together have made Macbeth’s ideas and opinions change complete ly. In act two, scene 1, Banquo and Fleance are walking along the hall way of Macbeth’s castle. Banquo tells his son, Fleance, about him being unable to sleep properly due to cursed thoughts and dreams. This shows that the three witches are having an effect upon Banquo. When Banquo and his son are confronted by Macbeth in the hall way, Banquo speaks of the witches telling some truth. Macbeth replies in an innocent way and says, â€Å"I think not of them./ Yet when we can entreat an hour to serve,/ We would spend it in some words upon that business†¦Ã¢â‚¬  Macbeth is telling Banquo a blatant lie about his thoughts and feelings about the witches. Macbeth tells Banquo that he has thought nothing of them since the night they both confronted them. They then both agree to talk about the subject of the witches and their prophecies at a later time. Lady Macbeth’s plans have made Macbeth lie to his own friend and a great friend of that who he fought with side by side in battle. If Macbeth had told Banquo the truth in that he had been thinking about the witches a lot of the time, Banquo may suspect something when the king is killed in Macbeth’s own home and then Macbeth becomes king! Banquo’s knowledge of the witches’ prophecy makes him both a potential ally and a potential threat to Macbeth’s plotting. For now, Macbeth seems distrustful of Banquo and pretends to have hardly thought of the witches, but Macbeth’s desire to discuss the prophecies at some future time suggests that he may have some sort of conspiratorial plans in mind. The appearance of Fleance, Banquo’s son, serves as a reminder of the witches’ prediction that Banquo’s children will sit on the throne of Scotland. We realize that if Macbeth succeeds in the murder of Duncan, he will be driven to still more violence before his crown is secure, and Fleance will be in immediate and mortal danger. Ambition and determination from both Macbeth and Lady Macbeth will drive someone to killing Fleance or Banquo or even both at some point since these characters are potential threats in preventing Macbeth to remaining king of Scotland. As soon as Macbeth and Fleance depart and leave Macbeth alone, Macbeth imagines that he sees a dagger leading/pointing him in the direction to Duncan’s room. Macbeth tries to grasp the weapon and fails. He wonders whether what he sees is real or a, â€Å"A dagger of the mind, a false creation,/ Proceeding from the heat-oppressed brain?† Macbeth decides that the vision of the dagger was simply a manifestation of his unease over killing Duncan. It is obvious that Macbeth is not overly confident nor enthusiastic about the matter of murdering Duncan but his ‘lover’ has literally forced him into this position through mockery and ambition. As Macbeth hears the signal of the bell rung by Lady Macbeth he heads off to the king’s room and commits the murder and says, â€Å"I go, and it is done./ The bell invites me./ Hear it not Duncan, for it is knell/ That summons thee to heaven or to hell.† This is Macbeth’s concluding speech before going on t o commit the murder of Duncan. In act two at the beginning of scene one, Lady Macbeth is waiting for Macbeth to return, is found contemplating to herself about drugging the king’s guards and congratulating herself as to how bold she is to carry out such actions. She also asks herself what gave her such courage, evil or sinister spirits perhaps as she asked for earlier on in the play? She says this at the beginning of scene two act one, â€Å"That which hath made them drunk hath made me bold;/ What hath quenched them hath given me fire./ Hark! Peace!† She obviously doesn’t want anyone else to hear what she is saying since she appears startled when Macbeth enters. Macbeth appears dazed and obsessed with thoughts of damnation after committing the murder. Lady Macbeth notices the blood drenched daggers within the hands of Macbeth’s. She tells him to pull himself together after this dreadful mistake and also shouting, â€Å"Who’s there? What ho!† Lady Macbeth warns Macbeth that he may have woken the guards after that silly act of shouting and tells him to return the daggers to the guards as planned. Macbeth refuses and so Lady Macbeth places the daggers next to the guards herself. Effects of shock and disbelief are gradually setting into Macbeth and this can be seen by his type of language spoken. This can be seen when Lady Macbeths tells him to return the daggers and he replies, â€Å"I’ll go no more./ I am afraid to think what I have done./ Look on’t again I dare not.† Macbeth appears to be unable to face up to what he has done, not even to himself, and is ashamed of himself after carrying out the murder. He is in shock and in denial over the whole situation. Macbeth appears scared and frightened of his own actions and all of this because ambition from Lady Macbeth and Macbeth. As the two go to wash their hands and prepare to get changed into their night clothes there is a knocking on the door of the castle and the murderer and his accomplice frantically get changed so to enable no one to suspect them as the possible murderers. The effect on Lady Macbeth after her trip into Duncan’s bedroom is particularly striking. She claims that she would have killed Duncan herself except that he resembled her father sleeping. This is the first time Lady Macbeth shows herself to be at all vulnerable. Her comparison of Duncan to her father suggests that despite her desire for power and her harsh chastisement of Macbeth, she sees her king as an authority figure to which she must be loyal. Also after the murdering of Duncan an important aspect to remember is that physical evidence can be washed away, like the blood to be washed off the skin of the hands, but emotional and mental feelings cannot be so easily removed and disposed of. This can be seen a little later in the play when Macbeth begins to act disturbingly and struggles to hold in his feelings. In the first scene of act three, Banquo is summing up the current situation. He has now witnessed two of the witches prophecies coming true, why not the next? If the next prophecy comes true that means Banquo’s descendants shall become king. Ambition and hope is now feeding Banquo’s motivation towards believing that the next prophecy shall come true. Macbeth and Lady Macbeth are now attempting to put Banquo’s mind at ease by inviting him to a feast. Doing this they hope to prevent Banquo getting suspicious about the murder of Duncan and so not think it was Macbeth and Lady Macbeth who were involved in the murder. If they both tried to avoid any sort of contact with Banquo, it would seem suspicious and suspect since he is such a good friend of Macbeth’s. Macbeth goes onto tell Banquo that they must discuss the problem of Malcom and Donalbain fleeing and therefore possibly intending to plot against the crown. So far, Macbeth is covering is guilt very successfully and appearing genuine and true towards Banquo. A false sense of security is given from Macbeth towards Banquo. When Banquo departs, Macbeth remains on stage and begins a soliloquy. The soliloquy is of Macbeth’s thoughts about Banquo and the threat he holds with Fleance too. He speaks of how he may have killed Duncan only for their sake in the future to come. He fears killing Duncan has assisted them in becoming king a lot sooner than Macbeth wants. Macbeth’s best friend is now is worst threat. Banquo and Fleance are a great threat towards Macbeth’s position of kingship. Macbeth’s and his Lady’s ambition for wanting everything and nothing but the best in kingship is beginning to have its consequences. Macbeth now knows he must get rid of both Banquo and Fleance so to prevent any such threat remaining towards Macbeth and his position as king of Scotland. He speaks with two murderers to whom he had already spoken the day before, assuring them that their misfortunes are Banquo’s fault. He tries to urge them to take revenge upon Banquo and his family. He tries to persuade the two murderers that if they carry the intended job out, that then proves them to be ‘real’ men. They agree to the proposed job Macbeth is telling them to do and he stresses to kill both of them, Banquo and Fleance. Macbeth is now needing more people killed (to feed his ambition and determination in becoming king) although not carrying the offence out himself. This may be due to the fact that killing Duncan is taking effect and that Macbeth can not bear to kill another friend of his just for his good. This killing is an act of selfishness, greediness and desperation. He may not be carrying out the murder himself because he feels he is unable to kill such a dear friend and a friend he has fought side by side with in battle. He also may not want to murder Banquo and Fleance because it may appear suspicious if another murder occurs and no witnesses available to say where Macbeth was at the time. If people know where Macbeth is, they cannot suspect him of being guilty for the murder. Macbeth doesn’t want to risk being caught by anyone and so has appoint these two men to do the job for him. Macbeth has no hesitation in killing Banquo and Fleance, which shows his ambition and determination is driving his actions. Macbeth’s conscience is no longer a part of his decisions he makes. Ambition appears to have replaced common sense. He is organising the death of one of his best friends and his friend’s son just so he can remain as king. It’s hard to believe that the murders Macbeth is responsible for (in carrying out and planning) have all been down to prophecies told and Macbeth’s and Lady Macbeth’s ambition and determination in making the prophecies happen. Macbeth now appears more able and independent, since Lady Macbeth has had no say in the plan of killing Banquo and Fleance, that we are aware of. Lady Macbeth’s ambition and determination earlier on in killing Duncan is now consequently making Macbeth more determined to remain king. This is an awful consequence due to the fact that innocent friends and relatives of Macbeth’s are dying just so Macbeth and Lady Macbeth can preserve their hierarchal status. These are very selfish and ambitious ways of keeping it their own way, the way they want it to be. In scene two, act three, Lady Macbeth is urging Macbeth to put the past behind him due to being uneasy about how Macbeth is. Macbeth hints that he has a plan that is intended to be carried out that evening. He gives no details but he believes she will approve of his plans and actions. Macbeth, through Lady Macbeth’s eyes, is now appearing to be in full control of making sure that he remains king and she remains queen of Scotland. It is clear that Lady Macbeth is uneasy about it, but she covers her feelings when around Macbeth. After all it was her motivation and ambition that has made Macbeth what he is now both king but at the same time a ruthless killer if needs be just to hold the current position of king. It is clear now that Macbeth’s ambition is feeding his motivation. In scene four, this is where it all starts to go wrong for Macbeth and for Lady Macbeth too. Macbeth learns that only Banquo was murdered and Fleance escaped from the attempt at killing both. Macbeth is angered at this result and tells himself, â€Å"There the grown serpent lies;/ the worm that’s fled Hath nature that in time will venom breed†¦Ã¢â‚¬  He basically talks of how Banquo (the grown serpent) lies dead but the younger and growing boy, Fleance (the worm) is still at large and later in life he will pose a threat. Shakespeare refers to the pair as snakes and worms due to the fact that they can strike at any time and are hard to kill or catch. This sums up Fleance perfectly since he could strike at any time and therefore pose a threat, and also is hard to kill. This is disastrous for Macbeth and Lady Macbeth because it is Fleance that must be killed since he is the main threat towards Macbeth’s kingship. If Banquo survived suspicions would arise, but with Banquo dead and Fleance still alive, suspicions are still going to occur and also the threat is still at large for Macbeth and his lady. As the banquet begins and Macbeth sits down with his friends to eat he finds a ghost of Banquo sat in his seat. Invisible to anyone else at the banquet, Macbeth begins to talk to the ghost in the chair although through the eyes of the people attending the banquet it would appear to be Macbeth talking to a chair. If he starts saying too much he may give away information about murders that they have planned and carried out to the other guests. The side effects of the deception, ambition and lies are now beginning to take effect on Macbeth. He is hallucinating images of his victim which means he is worrying about the matter a great deal. All this is a consequence of over ambitious actions carried out by both Lady Macbeth and Macbeth himself. Shakespeare fundamentally shows ambition in two different ways in ‘Macbeth’. He shows how ambition can have dreadful consequences and how it can ruin your life. In Macbeth’s case he dies which is the ultimate price to pay for his ambition and attempting to change nature’s course. Shakespeare also shows ambition as a good thing through Banquo’s actions as he stays level headed and lives life each day at a time. Banquo and his role in ‘Macbeth’ represent the better side of ambition but Macbeth represents the worst side of ambition. Ambition is generally looked upon as a good aspect to a person, but Shakespeare successfully shows how ambition can be both good and bad and what consequences can occur if you have too much of it in ‘Macbeth’.
