What is Cloud Computing ?

What it is ? why it is? and am I in Cloud Computing?. My answer it – Yes if you are working with internet technology, You are related with cloud computing. While you are working on your personal computer with the internet connection, You are connected with the cloud networks.

In a cloud computing the resources of hardware and networking are shared over the internet. A company providing the services of cloud computing (like: Amazon, IBM) provides the network infrastructure world wide, where users share resources with lower cost. In cloud computing we don’t need to setup own server rooms, hardware, etc individually. We just use them through web browser even we don’t know where the servers situated.

For an example of Amazon cloud services. We just Login to our AWS management console through web browser and can create, manage server instances, s3 and many other services. It’s not to be bad to say a Single window management for all your network services.

Services of Cloud Computing ?

Cloud computing services are divided into three categories: Infrastructure as a Service (IaaS), Platform as a Service (PaaS), Software as a Service (Saas).

Benefits cloud computing ?

1. Low cost - Mostly cloud services are available with cheaper costs due to its resource sharing. Like cloud services providers take a full advantages of virtualization.

2. Easy to Manage - Cloud services are easy to manage, we don’t need to work physically with the devices.

3. Flexibility & Scalability - As much as my experience with cloud computing, It’s is very flexible, We can create servers within minutes. We can use or start any services with the few clicks only. The most impotent feature is Scalability. If our organization grows, we can add more service of upgrade existing services within a minute.

4. Pay-Per-Use Services - Most of cloud services providers offers to Pay-Per-Use services. it means there are no boundation of billing date time. Like if we started any server for 1 hours only, we need to pay for 1 hour only.
