Whatever said, in my opinion, this concept

cloud computing has reached so far, during its relatively short period of existence,
I see a long way ahead for this concept to

SaaS that offers productivity software and
email services. Also, there’s a huge trend
in mobile apps that operate in a SaaS
environment. For instance, most of the
banking apps and online shopping apps
are run on a SaaS cloud base.
