RedShift1 complains that GCP is "deprecating stuff". I wouldn't put doing regular updates in the same problem category as having to deal with part of your stack disappearing.
To me "I wish they would stop deprecating stuff" sounds like any part of the stack has something like a 1% or even 10% chance in any given year to be shut off.
I would expect that by carefully choosing your stack from open source software in the Debian repos, you can bring the probability of any given part being gone with no successor to less than 0.1% per year. As an example - could you imagine Python becoming unavailable in 2026? Or SQLite? Docker?
Fair - I’m not very experienced with GCP, but I’ve seen AWS keep the deprecation treadmill moving as well.
In general, if I’m going to be maintaining stuff, I guess I’d rather be maintaining cloud than like… old Solaris or something.
