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

• Manufacturing industry• Banking/Trading• Pension funds management• Construction

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
