Azure High Availability

Achieving High Availability that meets high SLA requirements is a tough requirement. Azure provides lots of features that enable High Availability for applications from the host and guest operating system to applications using its PaaS. Architects can use these features to get High Availability in their applications using configuration instead of building these features by scratch or being dependent on third-party tools.

In this section, we will see features and capabilities provided by Azure to make applications highly available. Before we get into the architectural and configuration details, it is important to understand Azure High Availability related concepts.
