A GST messaging platform tuned to 21× its expected peak
EY's GST compliance platform has to survive filing-deadline bursts. I designed the Apache Pulsar platform on AKS and tuned it through EY's performance testing.
- Deployed Pulsar with Helm: ZooKeeper StatefulSets, cert-manager TLS, JWT auth and automated sinks.
- Right-sized CPU and memory requests so autoscaled pods actually took traffic.
- Traced node CPU saturation in Grafana to Pulsar and the app sharing one node pool.
- Proposed dedicated AKS node pools as the path to 5,000 TPS.
