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), Global Configurations (GC) using Global Configuration Management (GCM), Report Builder (RB) using Jazz Report Service (JRS), Data Collection Component (DCC), Indexed data for reporting using Lifecycle Query Engine (LQE), and Linked Indexes using Link Index Provider (LDX) 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.
