Recommended Application Lifecycle Management (ALM) deployment topologies 6.0.0 to 6.0.4

• ALM-E1 Topology Diagram for v6.x:
  

(ALM-E3) Enterprise - Distributed / Linux / Oracle

This enterprise topology uses Linux for the server operating systems. It includes both DNG and DOORS/DWA as the RM applications. The applications are distributed across separate servers and WAS instances. A reverse proxy is used to ensure public URI stability. Oracle is used for the databases and is hosted on a separate server. Finally, licenses are served by a floating license server and Tivoli Directory Server provides the LDAP based user management, for all but DOORS/DWA, which uses Windows Active Directory Server. Note that the VVC application is only present in release 6.0 and has been incorporated in other applications in later releases. Additionally, Rhapsody Model Manager, first available in version 6.0.5, is now the recommended architecture management tool. If Rhapsody Design Manager continues to be used, it should be deployed on its own server.

Applying the topologies

Every customer's environment is different with unique, necessary and often immutable requirements and constraints. We recognize that these standard topologies may not provide enough detail to make them immediately implementable in some customer environments, but we wanted to describe several topologies with enough variability to give an indication of what is possible and where our recommendations start.

While we recommend customers start with a standard topology that is most applicable to them, we recognize they will need to make changes and customizations to support their own unique requirements and constraints. IBM will support your own implementations, but may ask you to describe which topology is most applicable to your deployment and ask you to document what is unique in your environment to expedite any potential support situation.

To aid you in documenting your chosen deployment topology, we have made the following Rational Software Architect (RSA) model files available:

• ALM standard topologies 6.x

These may be imported into RSA then further modified or expanded to represent your environment. Look at the Installation_Instructions.txt file for information on how to import the models into RSA.

Next steps

This topic is meant to briefly introduce these standard topologies and describe how they might be applied. Work is already underway to build upon and apply them. Subsequent updates to this topic and supporting topics will provide additional insight into their usage.

Future updates to this topic or supporting topics may cover:

• Deeper look at select topologies
• Provide suggested tuning parameters
• Consider high availability database topologies
• Begin to expand this topology model into other domains
• Discussion of strategic integrations with other IBM and non-IBM products.
