This article describes the architecture, topology, and specification of the Jazz.net self-host development environment.

The Jazz development team's self-host production IBM Engineering Lifecycle Management (ELM) system is called "JazzDev." JazzDev provides applications for Change and Configuration Management (CCM) using IBM Engineering Workflow Management (EWM), Quality Management (QM) using IBM Engineering Test Management (ETM), Requirements Management (RM) using IBM Engineering Requirements Management DOORS Next (DOORS Next), Global Configurations (GC) using IBM Engineering Global Configuration Management (GCM), Reporting using IBM Engineering Report Builder (ERB), data collection and data warehouse for reporting using IBM Engineering Data Warehouse (EDW), indexed data for reporting using Lifecycle Query Engine (LQE), and cross-product linked indexes using Link Index Provider (LDX). 

There are two staging/test environments for the JazzDev self-host environment. The first -- also known as "BluesDev" -- is for continuous daily sprint milestone ELM 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 sprint milestone ELM build before deploying to (upgrading) production JazzDev.
