Deployment example: IBM Jazz.net environment

Authors: DougIshigaki
Build basis: The Rational solution for Collaborative Lifecycle Management (CLM) 6.0.6 GA with iFix003 Sprint Milestone 2 - as of August 2018

This article describes the architecture, topology, and specification of the Jazz.net environment.

The Jazz development team's production CLM system is "Jazzdev." It provides Change and Configuration Management (CCM) using Rational Team Concert (RTC), Quality Management (QM) using Rational Quality Manager (RQM), Requirements Management (RM) using Rational DOORS Next Generation (RDNG), Report Builder (RB) using Jazz Report Service (JRS), Data Collection Component (DCC), and Lifecycle Query Engine (LQE) applications to the development teams.

There are two staging environments for Jazz.net/Jazzdev. The first -- also known as "Bluesdev" -- is for continuous daily sprint milestone CLM builds and is available for the development teams to test daily builds in a Jazzdev staging environment. The second staging environment -- also known as "Souldev" -- is used for staging and testing the final declared milestone CLM build before deploying to production Jazzdev.
