Cloud Computing

                                                            

Cloud computing could be defined as a tool which has changed the way of organised commercial computing and availing the computing options for very less cost and effort. Thought it has drawbacks as well, but the positive aspects are so influential that they cannot be overlooked, which has been reason for many innovations which has changed the computing scenario. This has dramatically changed the meaning of system and made very sophisticated system accessible to every level of the entities. Speed, scalability, security are the key areas being enjoyed by the users of cloud computers now. All these factors make using the cloud computing worthwhile as they are proving themselves crucial in success of any business. Cloud computing is a model for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction. We have been using the services of cloud computing for many years now, for example, Google Docs, Amazon’s EC2 (Elastic computing cloud) and S3 (Simple Storage Services).it is also an important evolution in the way that businesses and individuals consume and operate technology. Cloud computing makes IT infrastructure more dynamic, modular, and easy-to-consume. Cloud computing is a way to increase capacity or add capabilities on the fly without investing in new infrastructure, training new personnel, or licensing new software. Cloud computing encompasses any subscription-based or pay-per-use service that, in real time over the Internet, extends Information Technology's existing capabilities. It is an on-demand delivery model for IT services or applications with the characteristics of multi-tenant hosting, elasticity (variable capacity) and utility based billing.

Cloud Computing

Cloud Computing is very essential in today’s global e- commerce environment because with cloud computing customers do not own network resources, such as hardware, software, systems, or services; network resources are provided through remote data centre on a subscription basis; and network resources are delivered as services over the web. Now all the business existing are focusing in cost reduction. They tend to provide cheap service to their clients. In addition access to the highly sophisticated system is a crucial need of today’s market as customers are not ready to spend their valuable time for anything. So business are looking forward towards offering cheap and flexible services where cloud computing has proved itself as the base of today’s growing market with prices going downwards with every new development. It has shown many hopes as it is very helpful in reducing costs as the companies no more has to worry about investing in hardware and timely upgrades. In addition business can enjoy high level of flexibility in storage spaces along with highly automated system. Moreover, IT professionals can enjoy more mobility as they now don’t have to stick with their desk and can access to their system and data from almost anywhere in the world where they can find basic computer facilities. This ultimately allows them to focus on other various areas for new innovations apart from traditional problems like upgrades and similar computing issues. Simultaneously, it also saves companies from investing huge amount in systems and hardware which they can use in other areas and reduce the cost of business which in beneficiary both for service providers and users.
