What is cloud computing?Distributed computing on internet Or delivery of computing service over the internet.
Eg: Yahoo!,Gmail,Hotmail-
Instead of running an e-mail program on your computer,youlog in to a web e-mail account remotely .The software and storage for your account doesn’t exist on your computer– it’s on the service’s computer cloud.

HISTORYConcept evolved in 1950(IBM) called RJE(Remote job entry process).In 2006 Amazon provided first public cloud AWS (Amazon web service)

1. Clients or Client computers
Clients are the device that the end user interact with cloud. They are three types of clients: Mobile Thick Thin (Most popular)

Distributed servers
Often servers are in geographically different places ,but server acts as if they are working next to each other.

Datacenter
It is collection of servers where application is placed and is accessed via internet

Central Server
It Administers the system such as monitoring traffic , client demands to ensure everything runs smoothly. It uses a special type of software called Middleware. Middleware allow computer to communicate each other.

Deployment of cloud Service
Public cloud Private cloud Community cloud Hybrid cloud (Combined cloud)

Why cloud service is popular?
Reduce the complexity of networks. Do not have to buy software licenses. Customization. Cloud providers that have specialized in a particular area (such as e-mail) can bring advanced services that a single company might not be able to afford or develop. Scalability , reliability , and efficency. Information at cloud are not easily lost.

Application
Social network sites. E-mail sites. Search Engines. Many more services OVER THE INTERNET
