A STUDY ON CLASSIFICATIONS OF CLOUD
Keywords:Cloud Computing, SaaS, PaaS, IaaS
“The interesting thing about cloud computing is that we’ve redefined cloud computing to
include everything that we already do.” - Larry Ellison
Cloud computing is an emerging field that is expected to change the entire information
technology processes and IT market in the future. It is changing how we develop, deploy, and
use the information technology and the infrastructure that it runs on. Cloud Computing can
be defined as Internet-based computing in which virtually shared servers that are data centers
provide software, platform, infrastructure, policies and many resources.
Clouds can be classified in various types: Public, Private, Hybrid and Virtual Private. In this
paper we will understand the Different Classifications of Clouds – IaaS, PaaS, SaaS – Public,
Private, Community, Hybrid and also match Cloud Providers to Our Needs – Amazon, Google,
