Today cloud computing is emergency technology that has generated efficient option for future business environment as well as technology researchers. While cloud computing provide many features but still it has a lots of shortcomings that need to abolish and manage carefully. Problem like relatively high operating cost for public and private cloud. Here introduction of life cycle of cloud. This cycle help in taking the idea how and where the use of cloud brings wonders in society. Service Level Agreements (SLA) are rising like flames in field of IT. In case of growing the dynamic environment of the cloud is daily maintence is basic on Quality of Service attributes is necessary to enact SLAs. Also abundant other factors like most as trust (on the cloud provider) come into thoughtfulness, particularly for enterprise customers that might outsource its critical data. The complex temperament of cloud services grants a complicated means of managing SLAs. The context of this paper follows the different stages of cloud life and gives other fields view on SLAs in a cloud computing environment by the Web Service Level Agreement(WSLA) framework, developed for the SLA monitoring and SLA enforcement in the Service Oriented Architecture (SOA). We used the other supporting feature of WSLA to delegate monitoring and enforcement jobs to other entities in so as to solve the trust issues. We also presented the real world use case to validate the proposal.
