Horde Groupware is probably not the first collaboration software that comes to mind when thinking about deploying a new system. Perhaps it should. Contrary to most of the popular collaboration software on the market such as Open-Xchange, Scalix and Zimbra, the guys behind Horde understands how to write efficient code and use appropriate tools (no Java, just plain PHP).
Yes, perhaps it is a bit too simplistic for many organizations (eg. no Active Sync), but on the other hand it does not require a Quad-core Xeon with 4GB of RAM to handle 10 users, like Zimbra does (ok, perhaps that’s an exaggeration, but you get the point).
Horde Groupware on the other hand can run decently even with very limited resources. While it does not have all the bells and whistles the big guys does, such as built-in failover support, since it is built on standard unix components, you can solve such issues with standard unix tools too.
Since I’m a lot for lightweight alternatives, I thought it would be a healthy contrast to our library of virtual appliances to create a turnkey appliance for Horde Groupware. The appliance is built is using CentOS 5.4 with Horde Groupware Webmail Edition 1.2.5.
More information on the appliance is available here.
