Maintenance -Maintenance of cloud computing applications is easier, since
they do not need to be installed on each user's computer and can be accessed
from different places. So, it reduces the cost also.
Low Cost-By using cloud computing, the cost will be reduced because to take the
services of cloud computing, IT company need not to set its own infrastructure
and pay-as-per usage of resources.
Services in the pay-per-use mode- Application Programming Interfaces
(APIS) are provided to the users so that they can access services on the cloud
by using these APIs and pay the charges as per the usage of services.
