Yes, there are thee architectural components of Usergrid:
1) Usergrid Web application: runs on Tomcats (usually behind a load
balancer),
provides the Usergrid REST API and calls upon Cassandra for storage
and
ElasticSearch for indexing and query. The Usergrid configuration file
includes
a list of Cassandra and ElasticSearch hostnames to be used.
2) Cassandra cluster: Usergrid uses Cassandra to store data Entities,
Collections
and Connections between Entities.
3) ElasticSearch cluster: Usergrid uses ElasticSearch to index the
properties of each
Entity, and to implement queries against Collections and Connections.
There are are three "optional" components:
4) The Portal: an HTML5/JavaScript and Angular application that runs on
Tomcat
(or any web server) and provides a portal for administering Usergrid
orgs and apps.
5) AWS S3: Usergrid can be configured to use S3 for storage of uploaded
files (Assets).
Without S3, Usergrid will store Assets on the file system.
6) AWS SNS & SQS: Usergrid can be configured to do ElasticSearch
indexing
asynchronously, Entities to be indexed are put in an SQS queue and
index load is
shared across nodes in the cluster.
As I remember, the Cloud Formation template sets up the first 5 of the
above components
and you can pick the number of Usergrid nodes, ElasticSearch nodes and
Cassandra nodes
that are to be launched.
