Why we choose Tuleap
•Legacy reasons: first version of an ALM deployed in 2003, so before Tuleap
•A centralized tool, versus several tools, with a centralized user management
•Small cost for deployment and management lead us to choose Tuleap for 3 other use cases
•Limited cost scaling when usage increases, more logarithmic than linear
•Supported by the provider thru a contract defining strong Service Level Agreements

Configurations of Tuleap we made to meet our challenges
• A huge (~7500 users per year) centralized Tuleap instance shared with all the company for SW
development purpose but for other purpose, bound to Gerrit code review and several Git
mirrors for performance enhancements.
High Availability platform with real time replication of servers, data and database in 2 data
center.
• One Small Tuleap (~300 users) on an isolated network for highly confidential data dedicated to
secured data.
• One Medium Tuleap (~1000 users) on the internet for collaboration with external partners,
customers and suppliers.
• One Medium Tuleap dedicated to manufacturing organization for Test Programs, on a High
Availability platform with a Jenkins dedicated infrastructure.

Gains since our teams use Tuleap
• Regular phase-out of multiple Git and Subversion servers around the planet, decreasing
management and maintenance overhead for the company.
• Phase-out of some other forge or tracking systems with similar gains.
• Centralized data & application means more security and more control.
Why we recommend Tuleap
• Cost efficient solution, most of administration are delegated to users.
• Small set of human resources needed to manage our 4 instances.
