- Apache: This is the web server technology that acts as the reverse proxy and serves the content. You can serve multiple things from the same machine. It is configured using the httpd.conf file which can be found for this project in `${GIT_HOME}/configuration/httpd/conf`. Apache works by using directives, which are commands to control access, security, sources and direct traffic, to name but a few. Apache is modular so extra config can be found in conf.d (within the configuration directory). In this directory you can find the macros used, including those used for archiving.

- EC2: This is the amazon web service that hosts the instances that the servers run on. We use load balancers to direct traffic, specifically Application Load Balancers, which routes at the HTTP/S level, making them very powerful. You might also want to read up on security groups, target groups and VPCs (virtual private clouds).
