Clouds can provide users with a number of different benefits.
Many businesses large and small use cloud computing today There are a number of reasons why cloud computing is so widely used among businesses today.
Reduction of costs:unlike on-site hosting the price of deploying applications in the cloud can be less due to lower hardware costs from more effective use of physical resources.
Universal access- cloud computing can allow remotely located employees to access applications and work via the internet.
Up to date Software - a cloud provider will also be able to upgrade software keeping in mind feedback from previous software releases.
Choice of applications. This allows flexibility for cloud users to experiment and choose the best option for their needs. Cloud computing also allows a business to use, access and pay only for what they use, with a fast implementation time
Potential to be greener and more economical- the average amount of energy needed for a computational action carried out in the cloud is far less than the average amount for an on-site deployment. This is because different organizations can share the same physical resources securely, leading to more efficient use of the shared resources.
Flexibility– cloud computing allows users to switch applications easily and rapidly, using the one that suits their needs best. However, migrating data between applications can be an issue.
The cloud computing infrastructure is revolutionizing all fundamental areas of IT -from security and investment in infrastructure to application development.
Pre-Cloud Computing :Most IT departments spent an excessive part of their time on frustrating implementation, maintenance, and upgrade projects - without adding value to the company's bottom line.
Cloud computing is a general term for anything that involves delivering hosted services over the Internet. These services are broadly divided into three categories: Infrastructure-as-a-Service (IaaS), Platform-as-a-Service (PaaS) and Software-as-a-Service (SaaS). The name cloud computing was inspired by the cloud symbol that's often used to represent the Internet in flowcharts and diagrams.
In IaaS environments
Computational infrastructure is available over the Internet (e.g., compute, storage, and so on).
A variety of interfaces facilitate interaction.Services are provided on top of the infrastructure.
Feature application development platforms allow developers to leverage the resources of established organizations to create and host applications of a larger scale than an individual or small business would be able to handle
Feature application-specific capabilities (e.g., a service that provides customer management)
Allow organizations and developers to use business-specific capabilities developed by third parties. Examples of third-party business specific capabilities are
Force.com, which is provided by salesforce.com (the SaaS leader) to give enterprise users a platform to build and run applications and components bought from AppExchange or custom applications
Zoho, which provides a large suite of web-based applications, mostly for enterprise use when it comes to emerging technologies, there is one phrase that has drawn more controversy than others: cloud computing. Two words which have driven countless debates, caused numerous arguments in IT departments and, more often than we'd care to admit, have left many in the industry deeply confused.
But interest has continued to increase and many organisations have moved elements of their IT into the cloud. We've also become accustomed to the idea of storing our personal data in the cloud, Cloud Computing been used to speed up and reduce the cost of existing process
