We're using this logstash output plugin at the moment https://github.com/awslabs/logstash-output-amazon_es together with the instance profile based permission it works as it should.

We are considering switching to the normal logstash-output-es plugin together with a AWS v4 auth signing proxy to make the setup more portable/less tied to AWS. I have a basic signing proxy setup working based on nginx/openresty. If you're interested just let me know.
