It's a bit more muddled then that since AWS isn't using the true ElasticSearch bits but rather an OpenDistro fork of it that they created themselves. So is it still ElasticSearch? Mostly, but it's not exactly the same thing either. But of course AWS would want to leverage the name recognition of ElasticSearch...
Opendistro is not a fork, itβs a collection of plugins that work with the open source elasticsearch distribution, basically it replaces what used to be called x-pack (security etc.)
