Introduction of Cloud Computing

 

        Cloud Computing

A cloud service provider is a third-party company offering a cloud-based platform, infrastructure, application, or storage services.

A = Availability : It means cloud computing is available 24/7 hours

W= Web based/Internet based services. Cloud customers access cloud 

services through the internet

E=Elasticity: It means cloud customers can easily scale their use of resources up or down as their needs change

S=Shared Resources: Cloud customers share the cloud resources over the internet, just as water systems are shared by city residents

O=On-demand self services. They can simply sign up for the services, pay for what they need, and start using them

E=Economical: Cloud Computing is more cost-effective to many companies, especially for smaller ones.
