Opportunities Abound!

XaaS is less pure technology and more about how companies can harness a powerful technology to cut cost and lift efficiency By Dhirendra Pratap Singh, eGov Bureau

loud computing is a general term for anything that involves delivering hosted services over the Internet. These services can be divided into Infrastructure-as-a-Service (IaaS), Platform-as-a-Service (PaaS) and Software-as-a-Service (SaaS).

Says Asheesh Raina, principal research analyst, Gartner, “Xaas i.e. any thing as a service is a delivery model. It is a way how the services or any software will be consumed in future. Some parts of that are already in the process like what here is software as a service.

With IaaS, customers get on-demand computing and storage to host, scale, and manage applications and services through cloud vendors’ data centres. This allows customers to scale with ease and quickly meet the infrastructure needs of an entire organisation or an individual department, either globally or locally. EMC, HP, CRM, Google, Verizon are examples of IaaS providers. For the customer, say a government or a private enterprise, there is no need to buy and maintain servers, data centres, or to build backup and redundancy infrastructure.
