Commercial cloud computing vendors are expected to meet achievable QoS requirements, and if the entity is vigilant, sign legally binding SLAs promoting expectation fulfillment. To ensure effective SLAs, OLAs must be defined and developed prior to deploying any cloud computing service. These OLAs should cover expectations that assist the entity’s IT organizational structure in services delivery and contractual negotiations.

Consequently, an OLA should specify technical processes in terms meaningful to the cloud computing provider, and can support several SLAs.
