25. Service-Level Agreement (SLA)

A cloud SLA is a formal agreement between the cloud provider and the customer that defines the quality and terms of the cloud services being delivered.

It sets measurable expectations for service, including minimum service levels, availability, security, controls, processes, communications, and support.

The SLA also explains what happens if the provider fails to meet those requirements, including remedies or responses.

It should clearly state data ownership and define what happens to the data when the service ends, including return or destruction of data.

Important SLA points can include infrastructure and security standards, audit rights, costs for continuing or ending service, availability, performance, data security and privacy, disaster recovery, data location, data access, data portability, problem handling, change management, dispute resolution, and exit strategy.
