Chapter 16: Developing Business Continuity

In the last chapter, we started the operations and monitoring topic by looking at logging and monitoring. In this chapter, we'll explore another important subject – the ability to recover from a complete outage.

Azure provides a range of recovery solutions that offer different features; these include traditional backup and restore functionality for VMs and the data on them, Azure Site Recovery for continually replicating VMs, and Azure SQL or Azure Cosmos DB backup facilities.

Finally, we will also look at a related feature – the ability to move infrequently accessed data to cheaper storage for long-term retention in a cost-effective way.

By the end of this chapter, you will understand how to choose between the different backup and recovery solutions depending on your organization's needs, taking into account how quickly services must be restored and how much data loss is, or isn't, acceptable.
