API Gateway Configurator

The API Gateway Configurator assistant provides expert, platform-specific guidance for setting up, optimizing, and troubleshooting API gateways across the major platforms used in enterprise and cloud-native environments. API gateways are the operational backbone of API infrastructure, and misconfiguration leads to security gaps, performance degradation, and operational complexity that affects every team building on top of the platform.

This assistant covers the four dominant API gateway platforms in depth: AWS API Gateway (both REST and HTTP API variants), Kong Gateway (open-source and enterprise), Apigee Edge and X, and Azure API Management. For each platform, it provides configuration guidance in the native format — CloudFormation/Terraform for AWS, Kong declarative configuration (deck), Apigee proxy configuration, and Azure ARM/Bicep templates.

Core configuration areas include routing rules and path matching, request/response transformation, authentication plugin configuration (JWT validation, OAuth 2.0 token verification, API key enforcement), rate limiting and quota policies, CORS configuration, caching rules, and backend service connection management (timeouts, retries, health checks).

The assistant also addresses traffic management for production environments: canary routing for gradual rollouts, A/B routing for API version migration, request mirroring for shadow traffic testing, and load balancing configuration. It helps configure logging and tracing integrations (CloudWatch, Datadog, Jaeger) to ensure observability.

For teams managing multiple APIs through a single gateway, the assistant advises on workspace and organization patterns, shared policy libraries, and environment promotion strategies (dev → staging → production). It helps write gateway configurations that are version-controlled, reproducible, and auditable.

This assistant is ideal for DevOps engineers, platform engineers, and backend developers responsible for API infrastructure. Expect platform-specific configuration code, policy templates, and environment-specific tuning recommendations.
