Whether you are operating your servers on premises or in the cloud, a cloud service like Microsoft Azure, Amazon Web Services or Google Cloud Platform are ideal for supporting recovery of sites in case of hardware or communications failures. If your servers are primarily at your data center, having additional servers at that facility may not help your users if access is cut off due to a natural disaster or other event. Recent floods in North Carolina and South Carolina remind us of how infrastructure can be vulnerable to weather.
Microsoft Azure provides you a resource for building failover and maintenance sites which will be up and running even when your data center cannot be. Microsoft offers technical documentation and videos that take you through the steps of establishing recovery sites.
These techniques are based on several failover scenarios, including these:

These techniques are based on several failover scenarios, including these:
Failover | Source | Target |
---|---|---|
Azure to Azure | Azure region | Azure region |
VMware to Azure | Configuration server | Azure |
Physical machines to Azure | Configuration server | Azure |
Hyper-V managed by VMM to Azure | VMM display name | Azure |
Hyper-V without VMM to Azure | Hyper-V site name | Azure |
VMM to VMM | VMM friendly name | VMM display name |
There are many combinations of service and server types which are supported for failover scenarios, including virtual machines (VMware and Hyper-V), Windows, Linux, and other servers as well as database services such as SQL Server and MySQL.
Using Azure for recovery sites is a good way to become more familiar with cloud computing and learn about your costs based on actual workloads rather than models and simulations.
