These components that are part of a platform deployment:
- Application Server
- The Application Server is a web app that runs in the Apache Tomcat container, so it can be deployed as a standalone web server. That configuration is useful for testing, experimentation, and other low-volume scenarios:
- (Optional) Apache HttpD
- Alternatively, the Apache httpd web server can be used to serve static content. In that case, the platform runs as an application server behind the Apache httpd web server. Those instances can be running on the same server, or on different servers, so either of these configurations is possible:
- (Optional) Messaging Server
- The messaging server handles Twitter and Facebook traffic. It also provides for on-screen notifications when two people are viewing the same case.
- MySQL Database
- MySQL is a relational database with capacities for redundancy, failover, backup, distributed access, and transactional integrity. That platform makes data look like Java objects to application developers. That makes applications easier to develop. But under the covers, the reliability and robustness of a mature relational database provides for data safety and rapid access.
- Replicated Database
- Database replication is a virtual necessity for any successful deployment. It safeguards data, and it allows for efficient backup and reporting from the replicated database, to minimize response time to users.
- Memcached
- The MEMory CACHE Daemon (memcached) is an optional, but highly recommended process that stores frequently-accessed data in memory, so it can be retrieved with maximum speed.
