What is Capistrano?
Capistrano is an open source tool mainly used to deploy web applications from source code management (SCM) to one or more servers.

Solr is an open source enterprise search platform from the Apache Lucene project. Its major features include powerful full-text search, hit highlighting, faceted search, dynamic clustering, database integration, rich document (e.g., Word, PDF) handling, and geospatial search.

At Grio, we use EC2 to power almost all of our server needs. Amazon hosting provides a convenient means of housing a web server and database server, a wiki, and our client development environment. It’s a cost efficient solution for companies like ours, in that we can avoid the hassle or purchasing and maintaining hardware. The strategy allows us to add servers only when we need them and remove them when they are no longer needed. Since Amazon’s pricing structure is based on the duration of server’s up-time, we want to make sure that we only use a server when necessary.
