Dave Rosenberg, CEO of MuleSource, works with a lot of organizations that are starting their SOA journeys, and noticed that many make the same mistake: they spend all their time worry about the technical details of their implementations, but don't pay enough attention to governance.
In a new post here at ebizQ, Dave outlined what he sees as the five greatest mistakes in SOA governance:
1-Decentralizing common artifacts: "When common artifacts such as WSDLs, schemas or configs are scattered in various locations, organizations waste time searching for interfaces and schemas," Dave says. "This is because they lack a central authority for the published service interface, which discourages discovery and reuse across an enterprise."
2-Reinventing the wheel: Perhaps the biggest problem SOA was meant to correct. "Services and applications are often written again and again to perform the same function," Dave says. "As a result, many different versions of the same artifact are built and integrated, increasing development times and creating a huge maintenance cost burden." The solution is a centralized repository or registry available to the enterprise.
3-Hoping for best practices: "Developers may not inherently know best practices, and even if they do, they may not follow them every time," Dave says. Best practices can and should be enforced as enterprise-wide policies, anywhere from the build to the registry to people and processes.
4-Forgetting about service consumers: It is important to continuously be aware of how a service is being used by the final consumer at the end of the process, Dave says. He recommends adopting tools that track dependency management.
5-Inconsistent application deployment strategy: "Many application deployment strategies are ad-hoc, not well documented, and only understood by one person," Dave says. A registry and repository can help automate developer actions, and thus ensure consistency.
How far along are most organizations with their SOA governance? ebizQ recently conducted a survey on SOA governance trends, and I will be joining Christian Hastedt Marckwardt, solution marketing director with SAP, on Tuesday, April 29, at Noon Eastern Time in a special Webinar to discuss the survey results and implications. Be sure to join us for a compelling hour, as well as receive a complimentary copy of the complete survey results!
