Nothing is really future proof, though. If it makes if 5 years before any major changes, then it will be good. I don't disagree that eventually this could lead to the same kind of vendor lock-in, but, it is also performant, has support, and will work tomorrow with off the shelf parts. of course you could go with OSS, and while that might be a good technical solution, it doesn't necessarily make it a good business decision. AWS is available now, and its performance characteristics are well understood.
