1. Project Overview
1. Middleware Stabilization & Performance Program
Quarterly reporting surges overwhelmed IIS, Tomcat, and WebSphere stacks supporting regulatory dashboards. This engagement executed root-cause diagnostics and tuning that restored consistent response times while preserving governance change controls.
Highlights
- Performed full-stack telemetry capture across IIS, Tomcat, and Oracle layers to pinpoint bottlenecks.
- Delivered staged optimization waves that held SLAs during executive reporting windows.
- Embedded automated health probes and restart workflows to prevent regression.
Applications Stabilized12 revenue & reporting portals
Peak Throughput Target> 4,500 requests/min
PlatformsIIS, Tomcat, WebSphere, Oracle
Case Study Spotlight
Regulatory Reporting Window Secured
Financial reporting teams previously endured 8-12 minute load times during quarter close. The optimized middleware stack now sustains sub-2 second responses for the same dashboards during peak filing periods.
Key Moves
- Correlated thread dumps with APM traces to isolate Tomcat connector saturation.
- Balanced IIS ARR farms with intelligent warm-up scripts before peak windows.
- Coordinated deployment freezes with the PMO so tuning changes could be promoted safely.
Business Impact
- Quarter-close portal latency reduced by 78% at 95th percentile.
- Unplanned downtime incidents fell from 11 per quarter to 3 under monitored change control.
- Finance leadership reported zero missed regulatory submission deadlines.
