Solution
different types od cloud services:
SAAS
PAAS
IAAS
SAAS: SAAS means software as a service. that is the cloud , provides the software that is
recquired by the IT as a sevice.it is given to thecustomers on the basis of subscription mode.the
cloud will provide the license to deploy into the customers environment.there should be an
internet availability to use these facilities.the entire software is managed and controlled by the
cloud at the central place.it is provided from the central place to all the others who were
subsribed
PAAS:PAAS means platfarm as a service.this is the platfarm where we can easily do the
application with out buying the entire software which is very costly.so it is very helpful.it is also
provided by the cloud to its customers on subscription basis.and then it is used to design the
applications.

2. IAAS:IAAS means infrastructure as a service. the cloud provides all the necessary infrastructure
as s service to the customer on subascription basis.pap-per use basis.infrastructure in the sense
they may be servers,networks etc..
there are many benifits in using cloud:
the software,the infrasturcture,platfarms cost a lot but the recquirement of those is may end up
with the completion of the project then buying the entire things is not the correct way to get the
benifits.then we can approach the cloud and do the service level agreements and can use the
resources that are necessary on a subscription basis.
but the drawback is the security:
how long the data is secure when it is in the hands of the third party called cloud
this is the main drawback and this leads to apprehension among it professionals regarding the
cloud services.
so the greatest risk is also the
security,sharing the accessibility,authentication,accessibility,
