CLOUD COMPUTING INTRODUCTION The word “cloud” in cloud computing means that the architecture taking the form of a cloud which is easily accessible for users from anywhere in the world on demand. It has important links to management aspects and also helps in cost reduction. At present, it is common to access content across the Internet independently without reference to the underlying hosting infrastructure. This infrastructure consists of data centers that are monitored and maintained round the clock by content providers. Cloud computing is an extension of this idea wherein the capabilities of business applications are exposed as sophisticated services that can be accessed over a network. Cloud service providers are incentivized by the profits to be made by charging consumers for accessing these services. Consumers, such as enterprises, are attracted by the opportunity for reducing or eliminating costs associated with “in-house” provision of these services. This clearly demonstrates the utility of cloud computing in terms of business exhibiting both the demand and the supply side. This clear identification of the demand and the supply side has led to the emergence of cloud computing as a unique discipline in the field of information and communication technology. (HARTIG, 2010) Definition Cloud computing is a computing platform for the next generation of the Internet. This essay

Defines clouds, explains the business benefits of cloud computing, and outlines cloud architecture and its major components. A Cloud Computing platform dynamically provisions, configures, reconfigures, and deprivations servers as per the need. Servers in the cloud can be physical machines or virtual machines. Advanced clouds typically include other computing resources such as storage area networks (SANs), network equipment, firewall and other security devices. Cloud computing also describes applications that are extended to be accessible through the Internet. These cloud applications use large data centers and powerful servers that host Web applications and Web services. Anyone with a suitable Internet connection and a standard browser can access a cloud application . Cloud computing environments support grid computing by quickly providing physical and virtual servers on which the grid applications can run. Cloud computing is different from grid computing because Grid Computing involves dividing a large task into many smaller tasks that run in parallel on separate servers. Grids require many computers, typically in the thousands, and commonly use servers, desktops, and laptops. Clouds also support no grid environments, such as a three-tier Web architecture running standard or Web 2.0 applications. A cloud is more than collection of computer resources because a cloud provides a mechanism to manage those resources. Management includes provisioning, change requests, reimaging, workload rebalancing, deprovisioning, and monitoring. The Cloud Platform
