Usergrid system requirements?
From what I see of usergrid, I can think that the most hungry for resources component will be Elasticsearch, so to have a production environment that's working well, I guess you should start following ES' requirements:
- At least 8 GB of RAM
- At least 4 cores (the more cores you give Elasticsearch, the more love you get as it tends to works with a lot of threading, i.e. give more cores rather than more CPU processing power)
- Fast HDDs should perform fine
See this article on Elasticsearch.A last thing is that depending on your system, you can tune several settings on Elasticsearch to achieve a better throughput. (For instance see https://www.elastic.co/guide/en/elasticsearch/reference/master/tune-for-indexing-speed.html)
I have deployed latest version of Usergrid i.e. 2.1, which is working smoothly in apache-cassandra-2.1.20, apache-tomcat-7.0.85, elasticsearch-1.7.6 on single node of Cassandra on Ubuntu 16.04 with 8 GB Ram and 180 GB SSD. Hope this will help you.
