Why production-replay parity changes gateway migration risk

A practical view of proving behavioural equivalence before each cutover—across policies, routing, identity, caching and faults.

  • Inventory behaviour, not only configuration.
  • Create a sanitised replay corpus that represents real edge cases.
  • Make parity a release gate, then automate the evidence.

The AI gateway is becoming a control plane

How MCP, A2A, model routing, semantic caching, guardrails and Model Armor fit into a governable GenAI platform.

  • Treat agent and model traffic as enterprise integration.
  • Centralise policy without centralising every development decision.
  • Measure quality, security, latency and cost together.

DORA evidence should come from the delivery system

For financial services, resilient architecture is only half the job. The evidence needs to be continuous, traceable and usable.

  • Map controls to live platform telemetry.
  • Capture change, recovery and test evidence automatically.
  • Exercise the operating model—not just the technology.
