Cloud Computing

As we know about from the tittle that what we talk about in this article I talk about Cloud Computing so let's know first that what is cloud computing?

Cloud Computing is a general term which is used to deliver the hosting   services over the internet this was broadly divided into three categories:

• Infrastructure as a service (Iaas)
• Platform as a service (paas)
• Software as a service (saas)

A cloud service can be a private or public.  In private service cloud computing provides service to a limited no. Of persons. On the other hand public service gives anyone on the internet.

Cloud Computing Deployment models:

• A private service which provides the service to the limited users . For example vmware and open stack.
• A public service which the cloud service anyone on the internet like (amazon web service.)
• A hybrid cloud service which is the combination of public and private service companies use private service to run  critical workloads and to handle the workloads public service has been used.

Cloud Computing characterstics:

• Self - service provisioning: it provides this service to the end users which spin up any computer workload this eliminates the traditional IT administration to manage and compute resources.
• Elasticity: it provides elasticity to the users this eliminates the massive investments in the local infrastructure which is not active.
• Pay per use: it provides the user to pay for the workload and resources which they use.
