AWS was super greedy and honestly I’m glad elastic even survived their aggressive tactics.
In the early days AWS elastic offering was very weak. It had lots of foot guns and operational problems. We tried hard to use an more native elastic offering and would have preferred it, but it didn't exist.
The fact AWS crappy hosted ES gained any market share is more a testament to how bad ES sales practices were than anything else.
ES really missed the mark by not having a simple, self-serve sales model and instead going all in convoluted "contact a sales rep" enterprise model no one wanted to deal with.
Dozen of hours of useless phone calls, and just nonsensical numbers coming out weeks or months later. Only to go back to the well and try again with a new team of reps after the first team inevitably churned out before any real progress was made.
