Cloud computing is a model for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction.cloud computing customers do not own the physical infrastructure.Cloud computing users avoid capital expenditure (CapEx) on hardware, software, and services when they pay a provider only for what they use.Low shared infrastructure and costs, low management overhead, and immediate access to a broad range of applications

“Any Situation In Which Computing Is Done In ARemote Location (out in the clouds) Ratherthan on your desktop or portable Device.”
Cloud Computing Low Cost For User And Providers. Independence Of Device And Software. Efficient Utilization Of all the resources. Ability to continusly add new users andapplications . Data is secure with policies toprotect its security
What is Cloud Computing Shared pool of configurable computing resources On-demand network access Provisioned by the Service Provider6

Amazon web serviceSeveral large Web companies are nowexploiting the fact that they have data storagecapacity that can be hired out to others.Amazon is one of the foremost and mostreputed Cloud Computing service provider,Whichincludes:Simple Storage Service (S3)Elastic Compute Cloud (EC2)SimpleDB
Disadvantage1. Requires a constant Internet connection2. Does not work well with low-speed connections3. Features might be limited4. Can be slow5. Stored data might not be secure6. Stored data can be lost7. Harder to know who can alter the data andwhere they come from.
conclusion Thus cloud computing provide a super-computing power.This cloud of computerextends beyond a single computer orenterprise. In Future The Security and Reliability shall BeImproved By the Introduction of certainglobally accepted standard.
