Confluence/Overview

Overview

Overview

Confluence is a J2EE web application that can either run entirely on 1 instance or be split up into the following individual instances:

• Application Server - This is where the confluence web app will live, hosted by tomcat. by default will use port 8090
• Web Server (Reverse Proxy Server) (optional) - This allows you to host confluence with apache in front, allowing the use of ports under 1024, like 80 and 443.
• Database Server (optional) - while confluence can run fine with an internal DB, you can setup an external DB for confluence to use. By default atlassian recommends Postgresql or ms sql, though you can also get mysql and oracle working.
• External user directory (LDAP) (optional) - manage users outside of confluence.

Limits

The limits per confluence instance are as follows:

Most Spaces	1700
Most Internal Users	15K
Most LDAP Users	100K
Most Pages	80K

Recommended minimum system requirements

Application Server

Resource	Value
CPU	2GHz+ Quad core
RAM	6GB
Minimum DB Size	10 GB

Reverse Proxy Web Server

There are no minimum requirement past the Operating system. For CentOS 7 that would be:

Resource	Value
Disk Space	20GB
RAM	1GB

Database Server

PostgreSQL : Again, there are no minimum requirements, but the minimum for the OS like CentOS 7 would probably suffice.
MS SQL: Note, these are just for MS SQL, not taking into account he OS needs.

Resource	Value
CPU	2GHz+
Memory	1GB+
Disk Space	6GB

External user directory (open LDAP)

Again, there are no minimum requirements, but the minimum for the OS like CentOS 7 would probably suffice.
