### Can I combine multiple authentication methods on a single route?
Yes. Apache APISIX supports configuring multiple authentication plugins on a
single route. The gateway attempts each configured method in order and accepts
the request if any method succeeds. This is useful during migration periods or
when a route serves clients with different authentication capabilities.

### What is the performance impact of adding an API gateway to a microservices
architecture?
Apache APISIX, built on NGINX and LuaJIT, adds 1-2ms of latency per request
with a typical plugin configuration (authentication, rate limiting, logging).
For most microservices architectures where end-to-end request latency is
50-500ms, this overhead is under 2% of total latency. The operational benefits
of centralized security, observability, and traffic management significantly
outweigh the minor latency cost.

### How do I communicate rate limits to API consumers?
Document rate limits in your API reference and include them in onboarding
materials. Use standard rate limit response headers on every response (not just
429 responses) so clients can monitor their consumption in real time. Provide a
dedicated endpoint or dashboard where consumers can check their current usage
against their quota. For paid tiers, send proactive notifications when
consumers approach their limits.

### How many rate limiting layers should an API gateway enforce?
Apply at least three layers: a global rate limit to protect overall
infrastructure capacity, a per-consumer limit to prevent any single client from
monopolizing resources, and per-route limits for endpoints with expensive
backend operations. Use sliding window or leaky bucket algorithms rather than
fixed windows to provide smoother throttling behavior and prevent burst abuse
at window boundaries.

### How does an API gateway differ from a reverse proxy?
A reverse proxy forwards client requests to backend servers and is the
foundation of both load balancers and API gateways. An API gateway is a
specialized reverse proxy that adds API-specific features: authentication, rate
limiting, request transformation, API versioning, and developer-facing
analytics. NGINX, for example, can function as a reverse proxy, load balancer,
or (with extensions) an API gateway. Apache APISIX is purpose-built as an API
gateway with load balancing built in.

### How do the two gateways compare on gRPC and streaming support?
APISIX provides native gRPC proxying, gRPC-Web transcoding, and HTTP-to-gRPC
transformation out of the box, along with support for HTTP/3 (QUIC), Dubbo, and
MQTT protocols. Kong supports gRPC proxying and gRPC-Web through plugins, with
HTTP/2 support on both client and upstream connections. For teams heavily
invested in gRPC or multi-protocol architectures, APISIX's broader built-in
protocol support reduces the need for custom plugins or sidecars.

### What is the resource overhead of running APISIX in Kubernetes?
A production APISIX data plane replica typically requests 500m CPU and 256Mi
memory, handling 10,000-20,000 requests per second depending on plugin
configuration. The controller replica requests 200m CPU and 128Mi memory. For
most clusters, two data plane replicas and one controller replica provide
sufficient capacity and redundancy. These resource requirements are comparable
to other Kubernetes ingress controllers and negligible relative to the
application workloads they protect.

Yes. AI gateways manage all types of AI traffic, including direct LLM API

All four gateways support Kubernetes, but the depth varies. APISIX and Kong
offer dedicated ingress controllers with CRD-based configuration. Envoy

Traefik auto-discovers Kubernetes services natively. The emerging Kubernetes
Gateway API standard is supported by all four projects to varying degrees, and
is becoming the recommended approach for new deployments.

### Is an API gateway the same as an API management platform?
No. An API gateway is the runtime component that processes API traffic. An API
management platform is a broader category that typically includes a gateway, a
developer portal, API documentation tools, lifecycle management, and analytics
dashboards. The gateway is the engine; the management platform is the full
vehicle. Apache APISIX provides the high-performance gateway layer, and
organizations often pair it with additional tooling for the complete API
management lifecycle.

Yes. Protobuf serialization libraries exist for languages targeting

providers, including Cloudflare and Fastly, now support gRPC proxying at the
