Definition
A Service Level Agreement SLA is a formal contract between a service provider and a client that defines the level of service expected from the provider. It specifies the metrics by which the service is measured, the remedies or penalties if service levels are not met, and the responsibilities of both parties. SLAs are crucial for managing expectations and ensuring accountability in technology service delivery. They provide a clear framework for performance monitoring and dispute resolution. For instance, an SLA might stipulate that a cloud service provider must maintain 99.9% uptime for a web application. This differs from a standard contract by focusing specifically on the measurable quality and performance of ongoing services. Understanding SLAs is essential for IT professionals and appears on exams like CompTIA Security+ and AWS Certified Solutions Architect Associate.
