Question

I was wondering if anyone has had success or knows if TWiki runs well in High Availability mode (i.e. two machines are running duplicate copies of the software in order to allow for quicker access to data & information if an extremely large amount of users access the site on a daily basis.)

Thank you!

Sincerely, Brian Mahoney

Environment

TWiki version: TWikiRelease04x01x02
TWiki plugins: DefaultPlugin, EmptyPlugin, InterwikiPlugin
Server OS: openSUSE 10.2
Web server: Apache
Perl version:  
Client OS:  
Web Browser:  
Categories: Hosting

High availability and scaling are two separate things.

For high availability, get a machine with redundant parts:

  • Raid 5 disks
  • Dual power supply
  • ECC memory
  • Two network cards
  • etc.

For scaling, use a load-balanced webserver setup:

  • Load-balancer
  • 3 or more webservers, each running TWiki
  • Storage backend
  • All webservers point to the same TWiki data and pub on the storage backend via nfs.
