Cloud computing relies on sharing of resources to achieve coherence and economies of scale similar to a utility (like the electricity grid) over a network. At the foundation of cloud computing is the broader concept of converged infrastructure and shared services.
Cloud computing is the use of computing resources (hardware and software) that are delivered as a service over a network (typically the Internet). The name comes from the use of a cloud-shaped symbol as an abstraction for the complex infrastructure it contains in system diagrams. Cloud computing entrusts remote services with a user's data, software and computation.
There are many types of public cloud computing:-
Infrastructure as a service (IaaS)
Platform as a service (PaaS)
Software as a service (SaaS)
Storage as a service (STaaS)
Security as a service (SECaaS)
Data as a service (DaaS)
Test environment as a service (TEaaS)
Desktop as a service (DaaS)
API as a service (APIaaS)
The business model, using software as a service, users also rent application software and databases. The cloud providers manage the infrastructure and platforms on which the applications run.
End users access cloud-based applications through a web browser or a light-weight desktop or mobile app while the business software and user's data are stored on servers at a remote location. Proponents claim that cloud computing allows enterprises to get their applications up and running faster, with improved manageability and less maintenance, and enables IT to more rapidly adjust resources to meet fluctuating and unpredictable business demand.
There are many India Companies offering Cloud Computing Services, some of them are:-
1. www.softlayer.com
2. www.netapp.com
3. www.gogrid.com
4. www.lanostechnologies.com
5. www.progressive.in
There is a huge scope in this field but like any where else, only the best get the best salaries.
