For the longest time, elastic didn't even have a cloud offering. And by the time they did it was far far too late.
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 anti AWS rhetoric is exhausting.
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.
