Cloud computing is an on-demand service that has obtained mass appeal in corporate data centers. The cloud enables the data center to operate like the Internet and computing resources to be accessed and shared as virtual resources in a secure and scalable manner.
The Cloud offers three primary services, which can be matched as per your unique requirements in Cloud Computing:
1- SaaS: Software as a service (SaaS) is a software distribution model in which a third-party provider hosts applications and makes them available to customers over the Internet.
2- PaaS: Platform as a service (PaaS) is a complete development and deployment environment in the cloud, with resources that enable you to deliver everything from simple cloud-based apps to sophisticated, cloud-enabled enterprise applications.
3- IaaS: Infrastructure as a service (IaaS) is an instant computing infrastructure, provisioned and managed over the Internet.
Why cloud computing beneficial for small business?

– Cloud computing is more cost effective – Because companies don’t have to purchase equipment and build out and operate a data center, they don’t have to spend significant money on hardware, facilities, utilities and other aspects of operations.
– Expenses can be quickly reduced – During times of recession or business cut-backs (like the energy industry is currently experiencing), cloud computing offers a flexible cost structure, thereby limiting exposure.
– Less environmental impact – With fewer data centers worldwide and more efficient operations, we are collectively having less of an impact on the environment. Companies who use shared resources improve their ‘green’ credentials.
