Cloud Computing supports On-Demand availability of Computer Resources.The delivery and use of compute resources occurs over the internet and is located in data centers.Data centers are centralized locations where computing and networking equipment is located for the purpose of collecting, storing, processing, distributing or allowing access to large amounts of data. One of the major advantage of cloud computing is that it eliminates the need to maintain server, storage and hardware,which in turn reduces the need for organizations to invest in and maintain their own on-premises IT resources.
Why we need of Cloud computing?
Location independence along with data storage.
Computing and networking is made possible with the cloud computing.
Information can be accessed easily from anywhere and any devices connected with internet.
