Question 1

How do I install APISIX on Kubernetes?

Accepted Answer

APISIX can be deployed on Kubernetes using Helm charts from the apisix-helm-chart repository. You'll need to set up etcd separately or use a managed service, and configure routes via the ingress controller or Admin API.

Question 2

APISIX vs Envoy: which is better for microservices?

Accepted Answer

APISIX offers dynamic updates without restarts and a richer built-in plugin ecosystem, while Envoy provides more fine-grained control at the proxy level. APISIX is often preferred for its ease of use and multi-language plugin support.

Question 3

Can APISIX handle gRPC traffic without transcoding?

Accepted Answer

Yes, APISIX supports gRPC proxying natively through the gRPC proxy plugin, allowing direct gRPC traffic without JSON transcoding, though transcoding is available via the grpc-transcode plugin if needed.

Question 4

What plugins are available for rate limiting in APISIX?

Accepted Answer

APISIX provides multiple rate-limiting plugins including limit-req, limit-count, and limit-concurrency, which can be configured per route or globally to control traffic based on requests, counts, or connections.

Question 5

How to secure the APISIX Admin API?

Accepted Answer

By default, the Admin API only allows 127.0.0.1 access; you can modify the allow_admin field in config.yaml to specify allowed IPs and use key authentication, as noted in the REST Admin API documentation.

Question 6

Does APISIX support serverless functions with AWS Lambda?

Accepted Answer

Yes, APISIX integrates with AWS Lambda via the aws-lambda plugin, allowing you to proxy requests to Lambda functions as dynamic upstreams, with support for API keys and IAM authentication.
