It’s not backed by Azure DevOps, the infrastructure is different and maintained by GitHub. However, the underlying technology is based on the Azure Pipelines technology (a sort of fork).
Not sure I understand. From my understanding Azure Pipelines is a service offered as part of Azure DevOps. Does this make the offerings of Azure Pipelines redundant?
Azure Pipelines remains available and it offers extra features that won’t be in GH Actions - like support for repos outside of GitHub (BitBucket, or Git anywhere)... it also supports SVN and TFVC.
Pipelines is also tightly integrated with Azure and has a richer CD experience (eg the K8s integration)
