API gateway architecture and scaling consulting
RTZ Labs provides API gateway architecture consulting – designing, reviewing, and scaling the edge layer that routes traffic into your services, including Envoy-based gateways, Kubernetes ingress, and AWS managed gateways.
The gateway is where every request enters, which makes it both the highest-leverage place to enforce policy and the easiest place to build a bottleneck. Common failures are structural: rate limiting applied per-instance so the effective limit scales with replica count, authentication on the hot path adding latency to every request, or routing rules accumulated to the point where no one can predict which one matches.
What we do with API Gateway
- Design edge and gateway architecture, including the boundary between gateway and service mesh
- Review routing rules for correctness, precedence, and predictability as they accumulate
- Analyze rate limiting strategy, including the difference between per-instance and global enforcement
- Review authentication and authorization placement and its latency cost on the request path
- Assess gateway scaling behavior, connection handling, and failure isolation
- Plan migrations between gateway implementations without a cutover outage
Problems we are called in for
Usually described this way before anyone knows the cause.
Scope and boundaries
We work with Envoy-based gateways, Kubernetes ingress controllers, and AWS managed gateways. Gateway work usually accompanies mesh or platform engagements rather than standing alone.
