Paul Sterling, a ProWorks Advisor, and Benjamin Carleski, Senior Developer, have teamed up to detail the ProWorks solution for an Azure failover instance with Umbraco Cloud. This allows for extremely low downtime and safer deploys while still leveraging all the great things about Umbraco Cloud.
Skrift is a community Umbraco web magazine that publishes original articles about developing in Umbraco as well as user experience, design, front-end technologies and broader issues like improving our community and quality of life.
Paul and Ben believe in Umbraco Cloud, but it lacks geo-redundancy for the service (AKA failover) and load-balancing for individual projects. Spurred on by (rare) outages in early 2019, they've created a failover environment to use with Umbraco Cloud. Better yet, they've shared with us their solution, which is useful for cases such as zero downtime upgrades and blue-green deployments
