what is the minimum number of instances necessary to get SLA guarantee from Microsoft
Answers
Explanation:
Cloud Services and Virtual Machines
For all Virtual Machines that have two or more instances deployed in the same Availability Set, we guarantee you will have Virtual Machine Connectivity to at least one instance, at least 99.95% of the time.
To receive Service Level Agreement (SLA) guarantee from Microsoft, the following minimum number of instances is necessary:
- Azure Virtual Machines (VM) - At least two instances are required to receive a 99.95% SLA.
- Azure App Services - A minimum of two instances is required to receive a 99.95% SLA.
- Azure SQL Database - For single databases, a minimum of two instances is required to receive a 99.99% SLA. For elastic pools, a minimum of four databases is required.
- Azure Cosmos DB - A minimum of two instances is required to receive a 99.999% SLA.
- Azure Functions - A minimum of two instances is required to receive a 99.95% SLA.
It is important to note that these minimum requirements apply to individual services. The overall SLA for a multi-tiered application will depend on the combination of services used.
Additionally, some additional factors such as region and network configuration can affect the availability guarantee.
In conclusion, meeting the minimum number of instances for each service is necessary to receive the SLA guarantee from Microsoft, but other factors may also come into play.
