Google sure is nowhere near as capable or even willing as Microsoft or Amazon; heck even IBM through Red Hat could prove a much better steward for its enterprise customers. But I think the morality is to never put all your eggs in the same basket, because any of them can fail for external reasons — e.g. horror stories about people locked out of any service because payments failed due to some stupid action by their bank; months to fix issues... don't be that guy/business with a single point of failure. So, contingency plans, and a healthy distribution of your flows. Have several banks/cards, several clouds, front load balance with a cross-platform HA solution, then for everything behind peg providers against each other; optimize for cost or convenience or whatever. This is the resilient way; and possibly even antifragile as you develop new synergies in this meta-space. It also sends a message that interop is value to you, to the market. When you operate at that level, there may be room for GC in your system — typically where you can afford it to fail / disappear but it's better/cheaper as long as it lives. You're already ready for the day it dies, because you make that risk assessment a parameter in your arch.
