Summary
In this chapter, we focused on improving the reliability of our services running on Azure VMs by discussing options for securing data via snapshots and backups. When implementing those features, make sure you plan for additional storage capacity needed (as backups will need additional disk space to be stored) and increased cost of your Azure infrastructure. Anytime BC and DR are considered, pay extra attention to cost calculation. It’s very easy to lose control over Azure spending when implementing those services, and you never want to spend more on them when compared to potential financial loss during outages.
In the next chapter, we’ll revisit managed disks in Azure by diving into more advanced topics such as attaching/detaching disks, resizing, and swapping OS disks on the fly.
