What is the purpose of a Service Level Agreement (SLA)?

The purpose of a Service Level Agreement (SLA) is to define the expected level of service between a provider and a customer. An SLA sets clear expectations about the services provided, including the quality, availability, and responsibilities of both parties. This agreement typically outlines metrics that will be used to measure the service performance, such as uptime guarantees, response times for support requests, and the processes for reporting and addressing any service issues.

By establishing these parameters, an SLA provides a framework for accountability and helps ensure that both the service provider and the customer have a mutual understanding of what is expected in the service relationship. This alignment is critical for effective communication and satisfaction on both sides, thereby fostering a stronger partnership.

For example, if a cloud service provider includes an SLA with a guaranteed uptime of 99.9%, customers can confidently plan their operations based on the assurance that the service will be available nearly all of the time. This clarity and quantifiable commitment benefit the operational planning and risk management processes of both parties.
