Cloud computing, often referred to
as simply “the cloud,” is the delivery
of on-demand computing
resources—everything from
applications to data centres—over
the Internet on a pay-for-use basis.

WHAT IS SAAS?
 Software as a service (or SaaS) is a way of delivering applications over the
Internet—as a service. Instead of installing and maintaining software, you
simply access it via the Internet, freeing yourself from complex software
and hardware management.
 SaaS applications are sometimes called Web-based software, on-
demand software, or hosted software. Whatever the name, SaaS
applications run on a SaaS provider’s servers. The provider manages
access to the application, including security, availability, and
performance.

PAAS
 PaaS (Platform as a Service), as the name suggests, provides you
computing platforms which typically includes operating system,
programming language execution environment, database, web server
etc.
 PaaS is analogous to SaaS except that, rather than being software
delivered over the web, it is a platform for the creation of software,
delivered over the web.
 Examples: AWS Elastic Beanstalk, Windows Azure, Heroku, Force.com,
Google App Engine, Apache Stratos

 IaaS (Infrastructure as a Service), as the name suggests, provides you the
computing infrastructure, physical or (quite often) virtual machines and
other resources like block and file-based storage, firewalls, load balancers,
IP addresses, virtual local area networks etc.
 Examples: Amazon Web Services, Rackspace, Google Compute Engine
