1. Details about the next HCoop Architecture
This page will serve as the blueprint for the architecture that HCoop is constructing right now, to be colocated at Peer 1.
1.1. Network Overview
The architecture for the next hcoop.net network involves three physical servers:
- A back-end server, which will serve IMAP, MySQL, PostgreSQL, primary mail, and AFS.
- A public shell server for development and deployment of files to web server.
- A public web server, also used for daemon processes written by our users. This will eventually be one node of a web cluster.
1.2. High-Level Architecture Description
The new HCoop architecture initially involves three servers; one for user shell logins, one for back-end services, and one for web service. Our goal is to build an architecture that serves us well based on our current needs, and can be expanded for increased capacity in the future with little effort.
Based on this, we should have one shell server that users edit and develop their web sites from. This will allow users to modify files on one web server in the present, and a cluster as we grow.
1.3. Design Goals
We should be able to plug new web servers into our architeture in the future in a manner that doesn't break our software systems. We may also want to think about doing the same thing with shell and file services.
