90% of our systems are on the Cloud and many of them Open Source.
At Mentorware, we truly believe in the Cloud. We were one of the first to move to Cloud-based email and extensively use Google Apps for creation and collaboration. We use HR, CRM, virtual servers for all our engineering / testing apps. We have helped many corporate departments do the same thing and integrate back to in-house systems. Cloud is our Way and has been for a long, long time!
