Anth Kernan has a tool for us:
Microsoft maintains 77 services across 13 service categories, everything from Artificial Intelligence to Compute to Databases to Storage to Azure Orbital – this is a lot of code and infrastructure to maintain and evolve, often at pace. Inevitably some of these services will be retired, either as new services replace them or through investments in the Microsoft Partner ecosystem.
This article will provide an overview of the tooling that exists within Azure to obtain a single centralized view of Service Retirements and reduce the reliance on manually checking the Azure Updates feed and/or Email notifications.
