Problem

You would like to improve the performance of a multi-tier platform that is currently unsatisfactory, and to resolve problems that are blocking going into production.

Process

• Determine the performance objectives (response to user, load handling)
• Put a benchmark campaign in place
  - choice of test tools: for measuring the front-end response, and introspective sensors for the different application layers
  - mounting test scenarios
  - execution of tests and collection of the results
• Results analysis for detecting bottlenecks and possible risks of dysfunction
• Correction actions on:
  - data flows and procedure calls between layers
  - container configuration (application servers, database, ...)
  - possibly recommendations for improving the applications and the application architecture, when the cause of the slowness has been identified
• Return on investment: for most assignments, the return...

Benefits

• An application tailored to production
• Increased vision on the possible behaviour of the application under load
• An immediate ROI because of the economies realised on the infrastructure investments
