more opinionated advice: ElasticSearch and the entire "ELK" stack (Logstash+ElasticSearch+Kibana)is awesome; but don't use it as a primary data store. It's not meant for that even though some of us are using it as such.
and make a more than a mental note to cancel the domain name if you don't use it in a year's time. It's the re-occuring domain charges that really get you in the end. (no pun intended).
