Deployment scenario: one office

This is an example. Depending on your situation, you may want to regroup or split out the various services on fewer or more servers.


  • One physical office
  • Up to 20 team members at one main office
  • Dozens of team members working remotely, connecting in via the VPN

Required hardware

Server 1: Gateway

On premise device which provides

  • Gateway
  • Firewall
  • VPN
  • Print Server
  • Internal DNS
  • etc.


  • 2 network cards
  • RAM: 1 gig (Any new computer will have sufficient CPU and RAM)
  • A fixed IP address from your ISP

Server 2: Web and Real-Time Collaboration

  • Emails (IMAP and SMTP)
  • Public website with logins to access the Intranet (Wiki, Blog, Calendar, Trackers, etc.)
  • Real-time collaboration (XMPP, and WebRTC)
  • File server (shared drive)


  • IP address and domain name
  • RAM: 3 Gigs minimum for Videoconferencing.

Server 3: Email

In data center

  • Emails (IMAP and SMTP)
  • Calendars and Contacts
  • Webmail


  • RAM: Depends on number of users
  • IP address and domain name

Server 4: Virtual Machines

In data center or at the office

  • IP address: one per per VM if you want them accessible without the VPN
  • RAM: 2 to 3 gigs per running VM

Desktop and mobile clients

See Software Components


  • Work is planned to permit to manage emails / calendars / contacts on the same server as "Web and Real-Time Collaboration" taking advantage of JMAP
