Middleware analyst

Middleware analysts are computer software engineers with a specialization in products that connect two different computer systems together. These products can be open-source or proprietary. As the term implies, the software, tools, and technologies used by Middleware analysts sit "in-the-middle", between two or more systems; the purpose being to enable two systems to communicate and share information.

Middleware analysts look at the system of systems. They solve technical problems which involve large scale inter-disciplinary objectives with multiple, heterogeneous, distributed systems that are embedded in networks at multiple levels. Middleware analysts hold and maintain proficiency in middleware technologies. Middleware is computer software that connects software components or applications. A senior middleware analyst should be able to articulate why SOA is important to business. SOA is a central theme in most middleware analyst roles within organizations.

Middleware best practices promote usability and maintainability among the systems served. A few examples of best practices are included here to provide some insight as to how middleware addresses key principles of standards-based computing.

One common problem for middleware is the manner in which user-defined applications are configured so that queue references bypass queue alias definitions referring directly to the queue local or queue remote definition. Such a bypass of queue alias deviates best practices and should be corrected when the administrator and/or programmer can correct it within time and scope parameters. All references from user-defined applications should point to queue aliases. Then the queue aliases should point to the defined queue local or queue remote.

Queue aliases allow flexibility for middleware administrators to resolve or relieve production problems quickly. By using queue aliases, middleware administrators can redirect message flow, in the event of a service problem, without changes to the user-defined application. For example, if a queue local were overflowing, a middleware admin could change the queue alias to point to a temporary queue local, thereby allowing the user-defined application to continue its processing without interruption while the underlying root cause is corrected.
