websphere message broker in shared runtime environments
DESCRIPTION
WebSphere Message Broker in shared runtime environments. Typical environment configurations and common set-ups with regards to high availability and workload balancing. What kind of solutions do we see implemented on top of message broker what are the demands for these solutions in terms of availability and isolation? How do we cater for these needs in a shared runtime environment? Also takes a look at the organization developing solutions targeting a shared runtime environment and how different organizations pose different requirements and challenges. Presentation given at IBM Transaction & Messaging conference in Barcelon 2008.TRANSCRIPT

Introducing DataPowerGeneral lack of data and best pracicesGeneral lack of data and best pracices
• Why is there so little data, patterns and practices available out in the “wild”?
In our experience Because the products “just work”
Both good and bad Good: products proven as very stable for mission
critical operation Bad: if you break new ground or think “outside the
box” there’s not much experience, best practices available, assets or patterns
Introducing DataPowerExamples of mission critical deploymentsExamples of mission critical deployments

If the integration platform stop,the business stop
Introducing DataPowerShared runtime - Key takeawaysShared runtime - Key takeaways
• Isolate Execution Groups as the unit of isolation Examine your OS ability to limit resources for processes and/or users
• Automate Broker and EG creation
Permissions File system structures
Deployment Consider self-service deployment (at least for test/QA environments)
• Govern Development guidelines / harvest patterns / document key concepts Implementation patterns adapted to the runtime environment
Req/Rep, Pub/Sub, Fan in/out, Collection, FTP, File transfer etc Make sure the people responsible for governance participate in projects
themselves
