I'm trialing the AWS Elasticsearch service:
https://aws.amazon.com/elasticsearch-service/
Very easy to setup. Basically just hit deploy. I unfortunately can't get any of the Elasticsearch GUI's to connect (ElasticHQ, Elasticsearch Head) as CORS is not enabled in the AWS build, and there is no way to change the elasticsearch config, or install plugins that I can see.
Does anyone know how to change these options on AWS?
