Cloud computing has been one of the next important buzz words in IT industry. It includes different ranks of terms like utility computing, grid computing, clustering, virtualization, etc.
The term involves the delivery of computing as hosted services over the Internet. Cloud computing offers computation, software, data access, and storage services. Moreover it is noteworthy to mention that it does not require end-user knowledge of the physical location and configuration of the system which sends services.
These services are divided into there distinct groups named Infrastructure-as-a-Service (IaaS), Platform-as-a-Service (PaaS) and Software-as-a-Service (SaaS).
A cloud service includes three distinct characteristics that clearly differentiate it from traditional hosting.
Just have a look on them:
- It is flexible and elastic in the sense that a user can have as much or as little of a service as they want at any given time span.
- It is sold on demand with a measurement of minute or hour.
- Service can be managed fully by the provider here the only needed things are a personal computer and an internet access.
If we look back to find out the reasons of accelerated interest in cloud computing, we will get to see that significant innovations in virtualization, distributed computing and improved access to high-speed Internet and finally a weak economy are the main reasons of it.
This cloud may be of two kinds one is private and another is public. A public cloud can sell services to anyone through internet. On the other hand, a private cloud is a proprietary network or a data center that supplies hosted services to a limited number of subscribers. Here one thing should know, when a service provider uses public cloud resources to create their private cloud is called a virtual private cloud. Enthused by its massive success some most advanced companies have got into the domain to provide end-to-end solution on it, LNSEL is forerunner of them.
