Here are the most common reasons for using open source systems:

• Dramatic cost savings. Total cost of ownership tends to scale radically better because of its inherent flexibility: free distribution, free upgrades, ...
• Higher security requirements, see our security resources for more information
• Easier maintenance, automated, centralised or remote
• Amount of tools available for free, without strings attached: free as in freedom
• Performance and scalability. ie: Linux runs on anything from watches and mobile phones to the most powerful clusters in the world
• Modularity, ability to inter operate with other systems and protocols. Which makes migrations as transparent as can be

Backoffice

To reduce costs, and get a better, more reliable and secure infrastructure.

The Internet relies on open standards and Open-Source software (such as the Apache web server has over 66% market share) which can be used to provide a reliable and cost effective infrastructure.

Desktops

To reduce costs, deploy new technologies, maintain a higher level of control and security.

A wide range of solutions allows for varied approaches when it comes to migrating desktop systems: from partial migration (allowing for a smooth transition and keeping compatibility with older applications) to a completely new and secure desktop.
