Cloud computing can come in many forms
which is dependant on the type of service it
will provide. Therefore they are specifically

There are 3 different service models…
SaaS

3. SaaS – Software as a Service
Software as a service, otherwise known as
‘SaaS’ provides a software through the use of
the internet. The software has been developed
and maintained by the designer, therefore they
user cannot have access to control it.
4. PaaS – Platform as a Service
Platform as a service otherwise known as ‘PaaS’
gives a platform for the building and hosting of
the application. Therefore this is implementing
cloud infrastructure.

computer and cloud storage. This takes into
account power, cooling and networking.
