Explanation:
An Azure Service Level Agreement (SLA) is a formal agreement between Microsoft and a customer that defines the level of service and availability that Microsoft will provide for a specific Azure service.
The SLA typically includes metrics such as uptime, availability, and responsiveness, and specifies the guarantees that Microsoft will make in terms of meeting those metrics.
In more detail, an Azure SLA outlines the service level targets and credit system for Azure service, ensuring that customer will receive a credit towards their bill if they don't meet the agreed-upon service level. It guarantees a certain level of uptime (i.e. availability) for a given Azure service, and if that service falls below that level, customer may be eligible for a service credit to be applied to their account.
