But really, GCP is not the same as the consumer-facing products. GCP already has a lot of clout, and literally nothing I know in GCP has been deprecated/chopped just like that. GCP already has a huge following in its own right and it's very unlikely for GCP stuff to be axed, given how careful they are with implementing new features (I have interacted with numerous engineers, and often feature requests are taken with a lot of valid pushback to prevent feature creep).
This is something all cloud providers suffer from. What assurance do I get that pricing and quality of service remains stable? Amazon has the same problem. If I look into my billing console, I see an increase of used computing resources. From inactive projects. They still managed to use significant CPU-time. I would not be able to claim otherwise. As long as the costs remain low, this is not a problem. But you have to believe your cloud provider...
Still using my own server for anything in development or for personal stuff or file storage (have you looked at prices? It is basically free now). I mainly use cloud services because people want it fast and cheap but still need an option to scale the solution.
I am content with the services Amazon delivers, but I heavily expect some kind of bubble burst in the future. Development of infrastructure and management interfaces probably isn't cheap either.
So does Google have a better backend than Amazon or Microsoft? I couldn't tell. Only that Microsoft tends to be slower than the competitors, Google tends to ban random users and some of their own services, and just with that Amazon comes out on top. But the fear that a service is deprecated at one point is a permanent undercurrent.
