Notes:

• If using more than one Apache web server, consider using a load balancer to increase performance and redundancy. An authority-signed SSL certificate (non self-signed) should be loaded onto the load balancer if using this solution.

• If using more than one MySQL database server, consider using replication to ensure redundancy and assist in database backups from the replication server.

• The Office converters can be installed on the same Windows 7 server.

• TUSK relies heavily on an appropriate version of PERL, hence the reason why the Apache web server hosts are limited to CentOS 5.8.

• Please note that the minimums listed above are bare minimums and if used will result in a functioning installation, however it will suffer sever performance penalties.
