> I know I haven’t gone into a lot of specific details about GCP’s deprecations. I can tell you that virtually everything I’ve used, from networking (legacy to VPC) to storage (Cloud SQL v1 to v2) to Firebase (now Firestore with a totally different API) to App Engine (don’t even get me started) to Cloud Endpoints to… I dunno, everything, has forced me to rewrite it all after at most 2–3 years, and they never automate it for you, and often there is no documented migration path at all. It’s just crickets.
