WHAt IS CLOUD COMPUTING?

”

“ 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

PAAS Platform

IAAS

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
