Exercise 1 – exploring the SLA for a service – Azure Service-Level Agreements
Exercise 1 – exploring the SLA for a service
This section will look at the resources we can use to gather information on the SLA for a service; we will look at the SLA information for App Service, Virtual Desktop, Virtual Machines, and Load Balancer.
The following subsections cover how to complete this exercise. They have been segregated into tasks for ease of understanding.
Task – accessing the SLA summary for Azure services
- From a browser, go to https://azure.microsoft.com/support/legal/sla/summary:
Figure 12.1 – SLA summary for Azure services
Task – viewing the SLA for App Service
- From the SLA summary for Azure services page, scroll down and locate App Service.
- Note what Microsoft specifies they will guarantee and the amount of available time expressed as a percentage; note what doesn’t have an SLA.
- Click on View full details. You can open this in a new tab or window if you prefer.
- By looking at the SLA for the individual service, you will see a format that is the same across all services that you should familiarize yourself with.
- Expand and explore the content in the Introduction, General Terms, and SLA details sections:

7. You can view the Version History details of an SLA, download the SLA, and learn more about the service to go to the product information page for that service.
Task – viewing the SLA for Azure Virtual Desktop
- From the SLA summary for Azure services page, scroll down and locate Azure Virtual Desktop.
- Note that Microsoft does not offer a financially backed SLA for this service and that they use the language …strive to attain at least…, which means there is no guarantee on the service level available. They note that the Virtual Machine SLA covers the availability of any session hosts.
Task – viewing the SLA for a virtual machine
- From the SLA summary for Azure services page, scroll down and locate Cloud Services and Virtual Machines.
- Note the difference in what is guaranteed for virtual machines that have two or more instances deployed in the same Availability Set and any single-instance virtual machines using premium storage for all disks; ensure you deploy virtual machines in a way that provides the availability and SLA that you need.
- Click on View full details. You can open this in a new tab or window if you prefer.
- Expand and explore the content in the Introduction, General Terms, and SLA details sections.
Task – viewing the SLA for Load Balancer
- From the SLA summary for Azure services page, scroll down and locate Load Balancer.
- Note what Microsoft indicates they will guarantee and the amount of time available expressed as a percentage; note what type of Load Balancer SKU does not have an SLA provided.
- Click on View full details. You can open this in a new tab or window if you prefer.
- Expand and explore the content in the Introduction, General Terms, and SLA details sections.
In this exercise, we looked at the resources that we can use to gather information on the SLA for a service.
