Discussion
Cloud computing can be define as an internet based computing technology where platform,
information, storage and software are offered to customer on demand. There are three types of
cloud computing service provider in the current market as PAAS, SAAS and IAAS.
PAAS stands for Platform as a service where third party service provider offers software and
hardware tools for application development. In PaaS computing model, enterprises needs to
install in-house software on dedicated hardware to develop or run a new application. PaaS
providers only provides key services such as java development or application hosting. They
offers an optimized and resilient environment on which enable the installation of applications
and datasets (Garg, Versteeg & Buyya, 2013). So, user can concentrate on running and creating
applications rather than maintain and constructing them. Microsoft Azure is one of the popular
PAAS provider and provides computing platforms includes web server, database, operating
system and programming language execution environment. (Hashizume et al., 2013).
SaaS stands for Software as a Service and sometimes also called host software or web based
