What is Cloud


       In one word using someone else’s computer over network 🙂 , Yes you heard me right Instead of maintaining physical server , Dedicated internet line etc.. we are renting someone’s computer over network.

Cloud is mainly divided into three main parts.

1)Infrastructure as a Service (IAAS)
2)Platform as a Service (PAAS)
3)Software as a Service (SAAS)

Infrastructure as a Service (IAAS)

                If we want to rent only hardware like RAM,Processor, Hard disk , GPU etc.. then we will called it IAAS

Platform as a Service (PAAS)

             If we want to rent a hardware along with Operating System like Linux , Windows then we will called it PAAS

Software as a Service(SAAS)

                If we want to use any software/application which is already defined by someone in the cloud then we will called it SAAS. eg:Salesforce,RightNow,Workday etc…
