Current Issues

SOA is a structural approach for creating services which can be reused and shared. It transforms present vertical applications to different components known as services, which can be reused in different applications and provide better agility and savings to make cost effective and quick changes (Bowen, 2009). Cloud computing refers to any IT resource, such as database, storage, application services and development present outside the firewall which may benefit enterprise IT over the web. The basic benefit of cloud computing is that it lowers the expenses incurred by leveraging these resources as services, by utilizing and paying as needed. Cloud computing facilitates the utilization of IT resources which can be leveraged on demand (Linthicum, 2009).
