The Changing Nature of Music Industry free essay sample
One of the less visible but highly challenging aspects of the Internet is the impact it has had and is having on the entertainment business. This Is particularly the case with music. At one level its impacts could be assumed to be confined to providing new e-tailing channels through which you can obtain the latest CD of your preference for example from Amazon. Mom or CD-Now or 100 other websites. These Innovations Increase the choice and tailoring of the music purchasing service and monster some of the richness/reach economic shifts of the new Internet game. But beneath this updating of essentially the same transaction lies a more fundamental shift in the ways in which music is created and distributed and in the business model on which the whole music Industry is currently predicated.In essence the old model Involved a complex .NET;ark In which songwriters and artists depended on AR (artists and repertoire) to select a few acts, production staff who would record in complex and expensive studios, other production staff who loud oversee the manufacture of physical discs, tapes and CDC and marketing and distribution staff who would ensure the product was publicized and disseminated to an increasingly global market. We will write a custom essay sample on The Changing Nature of Music Industry or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page Several key changes have undermined this structure and brought with It significant disruption to the Industry.Old competencies may no longer be relevant whilst acquiring new ones becomes a matter of urgency. Even well-established names like Sony find it difficult to stay ahead whilst new entrants are able to exploit the economics of the Internet. At the heart of the change is the potential for creating, touring and distributing music In digital format a problem which many researchers have worked on for some time. One solution, developed by one of the Forerunner Institutes in Germany, is a standard based on the Motion Picture Experts Group (MPEG) level 3 protocol MPH.MPH offers a powerful algorithm for managing one of the big problems In transmitting music files that of compression. Normal audio files cover a wide range of frequencies and are thus very large and not suitable for fast transfer across the Internet especially with a population who may only be using relatively slow modems. With MPH effective compression is achieved by cutting out those frequencies which the human ear cannot detect with the result that the files to be transferred are much smaller. As a result MPH files can be moved across the Internet quickly and shared widely.Various programs exist for transferring normal audio files and inputs such as CDC into MPH and back again. What does this mean for the music business? In the first Instance aspiring musicians no longer need to depend on being picked up by AR staff from major companies who can bear the costs of recording and production of a physical CD. Instead they can use home recording software and either produce a CD themselves I OFF coatrooms, etc. In the process they effectively create a parallel and much more direct music industry which leaves existing players and artists on the sidelines.Such changes are not necessarily threatening. For many people the lowering of entry barriers has opened up the possibility of participating in the music business for example, by making and sharing music without the complexities and costs of a formal recording contract and the resources of a major record company. There is also scope for innovation around the periphery for example in the music publishing sector where sheet music and lyrics are also susceptible to lowering of barriers through the application of digital technology.Journalism and related activities become increasingly open now music reviews and other forms of commentary become possible via specialist user groups and channels on the Web, whereas before they were the province o f a few magazine titles. Compiling popularity charts and the related advertising is also opened up as the medium switches from physical CDC ND tapes distributed and sold via established channels to new media such as MPH distributed via the Internet. As if this were not enough, the industry is also challenged from another source the sharing of music between different people connected via the Internet. Although technically illegal this practice of sharing between peoples record collections has always taken place but not on the scale which the Internet threatens to facilitate. Much of the established music industry is concerned with legal issues how to protect copyright and how to ensure that royalties are paid in the right proportions to hose who participate in production and distribution.But when people can share music in MPH format and distribute it globally, the potential for policing the system and collecting royalties becomes extremely difficult to sustain It has been made much more so by another technological development that of person-to-person or POP networking. Sean Fanning, an 18-year-old student with the nickname the Anapest, was intrigued by the challenge of being able to enable his friends to see and share between their own personal record collections. He argued that if they held hose in MPH format then it should be possible to set up some kind of central exchange program which facilitated their sharing.The result the Anapest. Com site offered sophisticated software which enabled POP transactions. The Anapest server did not actually hold any music on its files but every day millions of swaps were made by people around the world exchanging their music collections. Needless to say this posed a huge threat to the established music business since it involved no payment of royalties. A number of high-profile lawsuits followed but whilst Anapests activities have been curbed the problem did not go away.There are now many other sites emulating and extending what Anapest started sites such as Neutral take the POP idea further and enable exchange of many different file formats text, video, etc. In Anapests own case the phenomenally successful site concluded a deal with entertainment giant Bertelsmann which paved the way for subscription-based services which provide some revenue stream to deal with the royalty issue. Expectations that legal protection would limit the impact of this revolution have been copyright law. Their Judgment said, History has shown that time and market forces often provide equilibrium in balancing interests, whether the new technology be a player piano, a copier, a tape recorder, a video recorder, a PC, a karaoke machine or an MPH player. 68 Significantly the new opportunities opened up by this were seized not by music Industry firms but by computer companies, especially Apple. In parallel with the launch of their successful -Pod personal MPH player they opened a site called tunes Inch offered users a choice of thousands of tracks for download at 99 c each. In its first weeks of operation it recorded 1 m. TTS and has gone on to be the market leader in an increasingly populated field, having notched up over mom. Downloads since opening in mid-2003. See Case Study 1. 1 of 4th Edition for update) ere writing may be on the wall for the music industry in the same way as the low cost marline business has transformed the travel business. Behind the music industry the next target may be the movie and entertainment industry where there are a;ready worrying similarities. Or the growing computer games sector with shifts towards more small scale developers using viral marketing to build a sales base.

Araby- Vanity Essays - Araby, Seven Deadly Sins, Vanity, Narration
Araby- Vanity The characters in Araby display a wide spectrum of vanity that encompasses a variety of people. The narrator of the story is the best example of vanity. He is obsessed with a girl that lives next door to him. He never remarks about her personality but does remark that her image accompanied me even in places the most hostile to romance. A mind that is only intrigued by images is the pinnacle of vanity. Another example of this vanity in the narrator is noted within other statements about the girl. The narrator remarks that her name sprang to my lips at moments in strange prayers. Her image and vision was now controlling his prayers and the girl is the only God that he now acknowledges within his narrow vanity filled view of the world. Also the narrator speaks about rarely thinking about the future, only present events are taken in due course. The narrator further states that his body was like a harp and her words and gestures were like fingers playing his emotions. This statement fully proves the amount of vanity that exists in the narrator. He is fully driven by beauty, and every aspect of beauty controls his life. The narrator conveys Joyce's view of vanity and displays this view with sinful intentions throughout the story. The pursued girl also displays this view of vanity in many instances. The girl is noted as twisting a silver bracelet while talking of the Araby bazaar. The girl was inadvertently displaying the richness of her life and hinting to the narrator to buying a gift for her. She may not even have wanted to go to Araby but points out her wishes as to get a free gift out of the ordeal. The narrator was obsessed with beauty and the girl was obsessed with materialistic beauty, which are both separate but equal vanity sins. The situational detail also displays vanity with examples of rash thought and selfish actions. The narrator decides to go to the Araby and purchase something for the girl. He notes that he cannot wait for the day of the festival and he chafed against the work of school. This rash decision shows how his vanity clouds his reason. Another example is noted when the narrator states that life stood between [him] and [his] desire. This displays a total shunning of hard work and decency; two things that are the foundation of good values and morals. A further example of selfish rash behavior exists within the narrator's anger in his uncle. The uncle accidentally forgets to hand the narrator money to go to Araby. Upon realizing this the aunt notices the narrator did not smile. The narrator is selfish for his own needs and is not in good spirits unless his selfish needs are met. He is totally driven to experience his sin of vanity and will not be stopped by a forgetful uncle or anything else th at could hinder his pleasure. Character traits and events that take place within Araby are used to portray the sin of vanity that is very dominant throughout the story. A predominant effect of vanity causes a degradation of the spirit and free thought. James Joyce provides the reader a glimpse into the selfishness of one boy's drive towards sin. English Essays

The Council of Nicea and the Arian Controversy
The Council of Nicea and the Arian Controversy The Arian controversy (not to be confused with the Indo-Europeans known as Aryans) was a discourse that occurred in the Christian church of the 4th century CE, that threatened to upend the meaning of the church itself. The Christian church, like the Judaic church before it, was committed to monotheism: all the Abrahamic religions say there is only one God. Arius (256ââ¬â336 CE), a fairly obscure scholar and presbyter at Alexandria and originally from Libya, is said to have argued that the incarnation of Jesus Christ threatened that monotheistic status of the Christian church, because he was not of the same substance as God, instead a creature made by God and so capable of vice. The Council of Nicea was called, in part, to resolve this issue. The Council of Nicea The first council of Nicea (Nicaea) was the first ecumenical council of the Christian church, and it lasted between May and August, 325 CE. It was held in Nicea, Bithynia (in Anatolia, modern Turkey), and a total of 318 bishops attended, according to the records of the bishop at Nicea, Athanasius (bishop from 328ââ¬â273). The number 318 is a symbolic number for the Abrahamic religions: basically, there would be one participant at Nicea to represent each of the members of the Biblical Abrahams household. The Nicean council had three goals: to resolve the Melitian controversy- which was over the readmission to the Church of lapsed Christians,to establish how to calculate the date of Easter each year, andto settle matters stirred up by Arius, the presbyter at Alexandria. Athanasius (296ââ¬â373 CE) was an important fourth-century Christian theologian and one of the eight great Doctors of the Church. He was also the major, albeit polemical and biased, contemporary source we have on the beliefs of Arius and his followers. Athanasius interpretation was followed by the later Church historians Socrates, Sozomen, and Theodoret. Church Councils When Christianity took hold in the Roman Empire, the doctrine had yet to be fixed. A council is an assembly of theologians and church dignitaries called together to discuss the doctrine of the church. There have been 21 councils of what became the Catholic Church- 17 of them occurred before 1453). The problems of interpretation (part of the doctrinal issues), emerged when theologians tried to rationally explain the simultaneously divine and human aspects of Christ. This was especially difficult to do without resorting to pagan concepts, in particular having more than one divine being. Once the councils had determined such aspects of doctrine and heresy, as they did in the early councils, they moved on to church hierarchy and behavior. The Arians were not opponents of the orthodox position because orthodoxy had yet to be defined. Opposing Images of God At heart, the controversy in front of the church was how to fit Christ into the religion as a divine figure without disrupting the notion of monotheism. In the 4th century, there were several possible ideas that would account for that. The Sabellians (after the Libyan Sabellius) taught that there was a single entity, the prosÃ
pon, made up of God the Father and Christ the Son.The Trinitarian Church fathers, Bishop Alexander of Alexandria and his deacon, Athanasius, believed there were three persons in one god (Father, Son, Holy Spirit).The Monarchianists believed in only one indivisible being. These included Arius, who was presbyter in Alexandria under the Trinitarian bishop, and Eusebius, Bishop of Nicomedia (the man who coined the term oecumenical council and who had estimated participation at a substantially lower and more realistic attendance of 250 bishops). When Alexander accused Arius of denying the second and third person of the Godhead, Arius accused Alexander of Sabellian tendencies. Homo Ousion vs. Homoi Ousion The sticking point at the Nicene Council was a concept found nowhere in the Bible: homoousion. According to the concept of homo ousion, Christ the Son was consubstantial- the word is the Roman translation from the Greek, and it means that there was no difference between the Father and the Son. Arius and Eusebius disagreed. Arius thought the Father, Son, and Holy Spirit were materially separate from each other, and that the Father created the Son as a separate entity: the argument hinged on the birth of Christ to a human mother. Here is a passage from a letter Arian wrote to Eusebius: (4.) We are not able to listen to these kinds of impieties, even if the heretics threaten us with ten thousand deaths. But what do we say and think and what have we previously taught and do we presently teach? - that the Son is not unbegotten, nor a part of an unbegotten entity in any way, nor from anything in existence, but that he is subsisting in will and intention before time and before the ages, full God, the only-begotten, unchangeable. (5.) Before he was begotten, or created, or defined, or established, he did not exist. For he was not unbegotten. But we are persecuted because we have said the Son has a beginning but God has no beginning. We are persecuted because of that and for saying he came from non-being. But we said this since he is not a portion of God nor of anything in existence. That is why we are persecuted; you know the rest. Arius and his followers, the Arians, believed if the Son were equal to the Father, there would be more than one God: but Christianity had to be a monotheistic religion, and Athanasius believed that by insisting Christ was a separate entity, Arius was taking the church into mythology or worse, polytheism. Further, opposing Trinitarians believed that making Christ a subordinate to God diminished the importance of the Son. Wavering Decision of Constantine At the Nicean council, the Trinitarian bishops prevailed, and the Trinity was established as the core of the Christian church. Emperor Constantine (280ââ¬â337 CE), who may or may not have been a Christian at the time- Constantine was baptized shortly before he died, but had made Christianity the official state religion of the Roman Empire by the time of the Nicean council- intervened. The decision of the Trinitarians made Ariuss questions heresy akin to revolt, so Constantine exiled the excommunicated Arius to Illyria (modern Albania). Constantines friend and Arian-sympathizer Eusebius, and a neighboring bishop, Theognis, were also exiled- to Gaul (modern France). In 328, however, Constantine reversed his opinion about the Arian heresy and had both exiled bishops reinstated. At the same time, Arius was recalled from exile. Eusebius eventually withdrew his objection, but still wouldnt sign the statement of faith. Constantines sister and Eusebius worked on the emperor to obtain reinstatement for Arius, and they would have succeeded, if Arius hadnt suddenly died- by poisoning, probably, or, as some prefer to believe, by divine intervention. After Nicea Arianism regained momentum and evolved (becoming popular with some of the tribes that were invading the Roman Empire, like the Visigoths) and survived in some form until the reigns of Gratian and Theodosius, at which time, St. Ambrose (c. 340ââ¬â397) set to work stamping it out. But the debate by no means was over in the 4th century. Debate continued into the fifth century and beyond, with: ... confrontation between the Alexandrian school, with its allegorical interpretation of scripture and its emphasis on the one nature of the divine Logos made flesh, and the Antiochene school, which favoured a more literal reading of scripture and stressed the two natures in Christ after the union. (Pauline Allen, 2000) Anniversary of the Nicene Creed August 25, 2012, marked the 1687th anniversary of the creation of the upshot of the Council of Nicea, an initially controversial document cataloging the basic beliefs of Christians the Nicene Creed.

The Jazz Festival of Atlanta Essay Example | Topics and Well Written Essays - 1000 words
The Jazz Festival of Atlanta - Essay Example Atlanta is the most populous city and the capital city of the state of Georgia in the United States of America. Atlanta is considered to be the ninth most populous metropolitan city in the United States. As of July 2006, the city of Atlanta had a population of 486,411 and a metropolitan population of 5,138,223, making it the nation's ninth-largest metro area. Residents of the city are known as Atlantans. After a little research about the festival, I came to know that the Jazz Festival is a 31-day schedule of events featuring internationally renowned jazz artists and activities throughout the Metro Atlanta area culminating in the three day outdoor music event in Atlanta's Piedmont Park (Events Management). As I was present at the festival, I saw performers at the Atlanta Jazz Festival included the Herbier Hancock Quintet, The Pete Escovedo Orchestra Sheila E., Laws Family and many more. In addition to the main stage, it was given in the events list that there will be a "Future of Jazz" artist's stage too at the event (Johnson). The Memorial Day Weekend festival features 3 performance stages - Main Stage, Smooth Jazz Stage and a Home Grown Stage. There were activities for the entire family including artist vendors, festival food options, jazz education seminars and a special Kids' Zone featuring children's activities (Matouk). It was a real thing to enjoy and I'm sure one would definitely be delighted to be a part of this event. The festival was organized at the Woodruff Park in Atlanta, Georgia (Office of Cultural Affairs, 2008). I saw the featuring of Atlanta based jazz artists performing during the 31 days in May and they were culminated with family fun and music in Woodruff Park. The Atlanta Jazz Festival is regarded as one of the Country's largest free jazz festivals.Everybody in our group enjoyed the presence at the festival. The festival was basically formed to celebrate the rich cultural heritage of our city and has blossomed into a celebration of our nation's contribution to human expression (Office of Cultural Affairs, 2008). The festival is believed to be an annual music showcase that celebrates jazz legends and up-and-coming jazz greats in venues throughout metro Atlanta during the month of May and culminates in a 3-day music festival on Memorial Day Weekend. According to the organizers of the festival, it is believed that the main aim of celebrating the festival is to expose and entertain a diverse audience of jazz aficionados, young jazz enthusiasts and musical artists to the rich heritage and variety of jazz as an authentic form of traditional music. The guide who was assisting us and taking us through the entire even said that, the Atlanta Jazz Festival brought legendary performers, up -coming talent, artists, vendors and Atlanta's finest restaurants, as well as youth ensembles and high school performers, together for one of the largest jazz festivities in the country (Franklin, 2008). People like us, who take part in the festival enjoyed the renowned sounds of live jazz nightly at bars and nightclubs throughout the metro Atlanta area including; Churchill Grounds, Apache Caf, Eye Drum Art & Music Gallery, Funk Jazz Caf and more for the entire month.

Early Music through the Baroque Period Assignment
Early Music through the Baroque Period - Assignment Example This book is accompanied by a CD narrated by Ben Kingsley. I found it enlightening because of its overview of orchestra, which it follows up with an array of instrument groups used in orchestras. The brief explanations of the instrument groupââ¬â¢s history and distinctive sound qualities However, it would have been better if the instruments were named where they were shown alone, rather than in small group photos, which I found odd. Nevertheless, the highlighting of individual instrument parts with clear labelling of their parts is very helpful, even though the instruments are only named in the smaller photographs showing them in orchestra groups. I agree with the post that the strings in this piece gave the entire performance a whimsical feel, although it would have been better to refer to the marimba, rather than the percussion. In fact, it puts the marimba, an instrument that is rarely given much space, in the centre stage. This post rightly notes that this piece almost follows the rules of tap-dancing, in that it only repeats long enough for the listener to catch its flow, before changing its step. In my case, I would have added the fact about the central character in the piece, a young girl on Christmas Eve, who awakens to romantic love and the wider world. The post makes an important point about this piece being Dvorakââ¬â¢s ninth and last symphony, but I would also have linked this with the fact that nine seems to be a magical number for most composers, such as Mahler, Bruckner, Schubert, and Beethoven.

Allocation of Resources in Cloud Server Using Lopsidedness
Allocation of Resources in Cloud Server Using Lopsidedness B. Selvi, C. Vinola, Dr. R. Ravi Abstractââ¬â Cloud computing plays a vital role in the organizations resource management. Cloud server allows dynamic resource usage based on the customer needs. Cloud server achieves efficient allocation of resources through virtualization technology. It addresses the system that uses the virtualization technology to allocate the resources dynamically based on the demands and saves energy by optimizing the number of server in use. It introduces the concept to measure the inequality in multi-dimensional resource utilization of a server. The aim is to enlarge the efficient resource utilization system that avoids overload and save energy in cloud by allocating the resources to the multiple clients in an efficient manner using virtual machine mapping on physical system and Idle PMs can be turned off to save energy. Index Terms-cloud computing, resource allocation, virtual machine, green computing. I. Introduction In cloud computing provides the service in an efficient manner. Dynamically allocate the resources to multiple cloud clients at the same time over the network. Now-a-Days many of the business organizations using the concept of cloud computing due to the advantage with resource management and security management. A cloud computing network is a composite system with a large number of shared multiple resources. These are focus to unpredictable needs and can be affected by outside events beyond the control. Cloud resource allocation management requires composite policies and decisions for multi-objective optimization. It is extremely difficult because of the convolution of the system, which makes it impracticable to have accurate universal state information. It is also subject to continual and unpredictable communications with the surroundings. The strategies for cloud resource allocation management associated with the three cloud delivery models, Infrastructure as a Service (IaaS), Platform as a Service (PaaS) and Software as a Service (SaaS), differ from one another. In all cases, the cloud providers are faced with huge, sporadic loads that contest the claim of cloud flexibility. Virtualization is the single most efficient way to decrease IT expenses while boosting effectiveness and liveliness not only for large enterprise, but for small and mid budget organizations also. Virtualization technology has advantages over the following aspects. Run multi-operating systems and applications on a single computer. Combine hardware to get hugely higher productivity from smaller number of servers. Save 50 percent or more on general IT costs. Speed up and make things easier IT management, maintenance, and the consumption of new applications. The system aims to achieve two goals: The capability of a physical machine (PM) should be enough to satisfy the resource requirements of all virtual machines (VMs) running on it. Otherwise, the Physical machine is overload and degrades performance of its VMs. The number of PMs used should be minimized as long as they can still satisfy the demands of all VMs. Idle physical machine can be turned off to save energy. There is an intrinsic exchange between the two goals in the face of altering resource needs of VMs. For overload avoidance, the system should keep the utilization of PMs Low to reduce the possibility of overload in case the resource needs of VMs increase later. For green computing, the system should keep the utilization of PMs reasonably high to make efficient use of their energy. It presents the design and implementation of an efficient resource allocation system that balance between the two goals. The following aids are, The development of an efficient resource allocation system that avoids overload in the system effectively while minimizing the number of servers use. To introduce the concept of ââ¬Å"lopsidednessâ⬠to measure the uneven utilization of a server. By minimizing lopsidedness, the system improves the overall utilization of servers in the face of multidimensional resource constraints. To implement a load prediction algorithm that can capture the future resource usages of applications accurately without looking inside the VMs. Fig.1 System Architecture II. System Overview The architecture of the system is presents in Fig.1. The physical machine runs with VMware hypervisor (VMM) that supports VM0 and one or more VMs in cloud server. Each VM can contain one or more applications residing it. All physical machines can share the same storage space. The mapping of VMs to PMs is maintains by VMM. Information collector node (ICN) collects the information about VMs resource status that runs on VM0. The virtual machine monitor creates and monitors the virtual machine. The CPU scheduling and network usage monitoring is manage by VMM. Assume with available sampling technique can measure the working set size on each virtual machine. The information collects at each physical machine and passes the information to the admin controller (AC). AC connects with VM Allocator that activated periodically and gets information from the ICN resource needs history of VMs, and status of VMs. The allocator has several components. The Indicator Indicates the future demands of virtual machine and total load value for physical machine. The ICN at each node attempts to satisfy the input demands locally by adjusting the resource allocation of VMs sharing the same VMM. The hotspot remover in VM allocator spots if the resource exploitation of any PM is above the Hot Point. If so, then some VMs runs on the particular PM will be move away to another PM to reduce the selected PM load. The cold spot remover identifies the system that is below the average utilization (Cold point) of actively used PMs. If so, then it some PMs turned off to save energy. Finally, the exodus list passes to the admin controller. III. The Lopsidedness Algorithm The resource allocation system introduces the concept of lopsidedness to measure the unevenness in the utilization of multiple resources on a server. Let consider n be the number of resources and let consider ri be the exploitation of the ith resource. To define the resource lopsidedness of a server p by considering r is the average utilization of resources in server p. In practice, not all types of resources are performance critical and then consider bottleneck resources in the above calculation. By minimizing the lopsidedness, the system can combine different types of workloads nicely and improve the overall utilization of server resources. A. Hot and Cold Points The system executes periodically to evaluate the resource allocation status based on the predicted future resource demands of VMs. The system defines a server as a hot spot if the utilization of any of its resources is above a hot threshold. This indicates that the server is overloaded and hence some VMs running on it should be migrated away. The system defines the temperature of a hot spot p as the square sum of its resource utilization beyond the hot threshold. Consider R is the set of overloaded resources in server p and rt is the hot threshold for resource r. (Note that only overloaded resources are considered in the calculation.) The temperature of a hot spot reflects its degree of overload. If a server is not a hot spot, its temperature is zero. The system defines a server as a cold spot if the utilizations of all its resources are below a cold threshold. This indicates that the server is mostly idle and a potential candidate to turn off to save energy. However, the system does so only when the average resource utilization of all actively used servers (i.e., APMs) in the system is below a green computing threshold. A server is actively used if it has at least one VM running. Otherwise, it is inactive. Finally, The system define the warm threshold to be a level of resource utilization that is sufficiently high to justify having the server running but not so high as to risk becoming a hot spot in the face of temporary fluctuation of application resource demands. Different types of resources can have different thresholds. For example, the system can define the hot thresholds for CPU and memory resources to be 90 and 80 percent, respectively. Thus a server is a hot spot if either its CPU usage is above 90 percent or its memory usage is above 80 percent. B. Hot Spot Reduction The system sort the list of hot spots in the system in descending temperature (i.e., the system handle the hottest one first). Our goal is to eliminate all hot spots if possible. Otherwise, keep their temperature as low as possible. For each server p, the system first decides which of its VMs should be migrated away. The system sort its list of VMs based on the resulting temperature of the server if that VM is migrated away. The system aims to migrate away the VM that can reduce the serverââ¬â¢s temperature the most. In case of ties, the system selects the VM whose removal can reduce the lopsidedness of the server the most. For each VM in the list, the system sees if the system can find a destination server to accommodate it. The server must not become a hot spot after accepting this VM. Among all such servers, the system select one whose lopsidedness can be reduced the most by accepting this VM. Note that this reduction can be negative which means the system selects the server wh ose lopsidedness increases the least. If a destination server is found, the system records the migration of the VM to that server and updates the predicted load of related servers. Otherwise, the system moves onto the next VM in the list and try to find a destination server for it. As long as the system can find a destination server for any of its VMs the system consider this run of the algorithm a success and then move onto the next hot spot. Note that each run of the algorithm migrates away at most one VM from the overloaded server. This does not necessarily eliminate the hot spot, but at least reduces its temperature. If it remains a hot spot in the next decision run, the algorithm will repeat this process. It is possible to design the algorithm so that it can migrate away multiple VMs during each run. But this can add more load on the related servers during a period when they are already overloaded. The system decides to use this more conservative approach and leave the system s ome time to react before initiating additional migrations. IV. System Analysis In Cloud Environment, the user has to give request to download the file. This request will be store and process by the server to respond the user. It checks the appropriate sub server to assign the task. A job scheduler is a computer application for controlling unattended background program execution; job scheduler is create and connects with all servers to perform the user requested tasks using this module. In User Request Analysis, the requests are analyze by the scheduler before the task is give to the servers. This module helps to avoid the task overloading by analyzing the nature of the users request. Fist it checks the type of the file going to be download. The users request can be the downloading request of text, image or video file. In Server Load value, the server load value is identifies for job allocation. To reduce the over load, the different load values are assign to the server according to the type of the processing file. If the requested file is text, then the minimum load value will be assign by the server. If it is video file, the server will assign high load value. If it is image file, then it will take medium load value. In Server Allocation, the server allocation task will take place. To manage the mixed workloads, the job-scheduling algorithm is follow. In this the scheduling, depends upon the nature of the request the load values are assign dynamically. Minimum load value server will take high load value job for the next time. High load value server will take minimum load value job for next time. The aim is to enlarge the efficient resource utilization system that avoids overload and save energy in cloud by allocating the resources to the multiple clients in an efficient manner using virtual machine mapping on physical system and Idle PMs can be turned off to save energy. Fig. 2 Comparison graph IV. Conclusion It presented by the design, implementation and evaluation of efficient resource allocation system for cloud computing services. Allocation system multiplexes by mapping virtual to physical resources based on the demand of users. The contest here is to reduce the number of dynamic servers during low load without sacrificing performance. Then it achieves overload avoidance and saves energy for systems with multi resource constraints to satisfy the new demands locally by adjusting the resource allocation of VMs sharing the same VMM and some of not used PMs could potentially be turn off to save energy. Future work can on prediction algorithm to improve the stability of resource allocation decisions and plan to explore using AI or control theoretic approach to find near optimal values automatically.

Imagine: Everyday thousands of people get killed in a war no-one asked for. Friends and family are send to a horrible place with little chance youââ¬â¢ll ever see them again. This war, a useless and disgusting war started without any reasons and only goes on because the leaders of your country are too proud to make it end. For millions of American citizens this nightmare became truth. In 1964 the American president Johnson started sending soldiers to Vietnam. At the end of the war in 1972, it is estimated that, in total, over 2,5 million people on both sides were killed. As the war continued, the American people got more and more unsatisfied and angry at their government. They wanted the war to stop, it had been going on long enough and too many people had been killed, president Johnson, ho...
