Software As a Service (SaaS) is an important layer of cloud computing. It provides cloud applications like Google is doing. It facilitate users to save their document on the cloud and create as well.

There are 3 layers in the hierarchy of cloud computing. Infrastructure as a service (IaaS):It provides cloud infrastructure in terms of hardware as like memory, processor, speed etc. Platform as a service (PaaS):It provides cloud application platform for the developer. Software as a service (SaaS)::It provides the cloud applications to users directly without installing anything… Continue reading 7) What are the different layers in cloud computing?
