Cloud computing is a cumulative collection of technologies. It shares on-demand computing resources that are positioned and disposed efficiently. In spite of several benefits, numerous challenges are there such as data security, performance, data locking, access control, bandwidth costs, internet dependency, data confidentiality, auditability, application and availability. SLA (Service Level Agreement) plays a vital role in cloud computing. Each service associates with a specific SLA. This is collaboration between service providers and consumer. Therefore, SLA has to define the level of security and their intricacy established on the services to make the consumer realize about the implementation of security policies.
