You can spin this as they release "MVP" software and let early users drive direction. I mean, that's what I've heard.
Yeah.. Except that's not how they spin it.
In practice, they wrap it in marketing speak to paint it as something to revolutionize your stack.
Then you jump in spending several days of engineering time diving into it, only to find late in the game that the one (or several) critical details you can't find in the documentation that are essential to making an end-to-end production ready pipeline, are not actually implemented yet...
And won't be for many months
Side note.. I'm a production AWS user, with no plans to change, but I feel like AWS does this exact same thing with each reInvent. The announced products actually become available 6-12 months later, and actually "useable" and reliable 2 yrs later...
