High availability disaster recovery (HADR) is an integral part of any organization’s data strategy. It is also an essential string to every DBA's bow. In an online world that operates 24 hours a day, going offline or losing customers' data cannot be tolerated. This lesson examines the features that Azure provides to help you make sure your SQL databases, whether they are managed in the cloud or on-premise, are not the point of failure in your systems.

High availability disaster recovery encompasses two fundamental concepts. Firstly, how to minimize the amount of time your databases will be offline in the event of unforeseen events like hardware failures, power outages, or any number of natural disasters. Secondly, it looks at how to minimize data loss when any of these events occur. It is one thing to be offline, but it is another thing to lose data that is already in your custody.

In this lesson, we will cover the full range of Azure options from turnkey to custom and do-it-yourself solutions. If you have any feedback relating to this lesson, feel free to reach out to us at support@cloudacademy.com.
