Apache APISIX

Apache APISIX is a dynamic, real-time, high-performance API gateway.

APISIX provides rich traffic management features such as load balancing, dynamic upstream, canary release, circuit breaking, authentication, observability, and more.

You can use Apache APISIX to handle traditional north-south traffic, as well as east-west traffic between services. It can also be used as a k8s ingress controller.

Features

You can use Apache APISIX as a traffic entrance to process all business data, including dynamic routing, dynamic upstream, dynamic certificates, A/B testing, canary release, blue-green deployment, limit rate, defense against malicious attacks, metrics, monitoring alarms, service observability, service governance, etc.

All platforms
- Cloud-Native: Platform agnostic, No vendor lock-in, APISIX can run from bare-metal to Kubernetes.
- Run Environment: Both OpenResty and Tengine are supported.
- Supports ARM64: Don't worry about the lock-in of the infra technology.
Multi protocols
- TCP/UDP Proxy: Dynamic TCP/UDP proxy.
- Dubbo Proxy: Dynamic HTTP to Dubbo proxy.
- Dynamic MQTT Proxy: Supports to load balance MQTT by client_id, both support MQTT 3.1.*, 5.0.
- gRPC proxy: Proxying gRPC traffic.
- gRPC transcoding: Supports protocol transcoding so that clients can access your gRPC API by using HTTP/JSON.
- Proxy Websocket
- Proxy Protocol
- Proxy Dubbo: Dubbo Proxy based on Tengine.
- HTTP(S) Forward Proxy
- SSL: Dynamically load an SSL certificate.
Full Dynamic
- Hot Updates And Hot Plugins: Continuously updates its configurations and plugins without restarts!
- Proxy Rewrite: Support rewrite the host, uri, schema, enable_websocket, headers of the request before send to upstream.
- Response Rewrite: Set customized response status code, body and header to the client.
- Serverless: Invoke functions in each phase in APISIX.
- Dynamic Load Balancing: Round-robin load balancing with weight.
- Hash-based Load Balancing: Load balance with consistent hashing sessions.
- Health Checks: Enable health check on the upstream node and will automatically filter unhealthy nodes during load balancing to ensure system stability.
- Circuit-Breaker: Intelligent tracking of unhealthy upstream services.
- Proxy Mirror: Provides the ability to mirror client requests.
- Traffic Split: Allows users to incrementally direct percentages of traffic between various upstreams.
Fine-grained routing
- Supports full path matching and prefix matching
- Support all Nginx built-in variables as conditions for routing, so you can use cookie, args, etc. as routing conditions to implement canary release, A/B testing, etc.
- Support various operators as judgment conditions for routing, for example {"arg_age", ">", 24}
- Support custom route matching function
- IPv6: Use IPv6 to match the route.
- Support TTL
- Support priority
- Support Batch Http Requests
- Support filtering route by GraphQL attributes
Security
- Authentications: key-auth, JWT, basic-auth, wolf-rbac, casbin, keycloak
- IP Whitelist/Blacklist
- Referer Whitelist/Blacklist
- IdP: Support external authentication services, such as Auth0, okta, etc., users can use this to connect to OAuth 2.0 and other authentication methods.
- Limit-req
- Limit-count
- Limit-concurrency
- Anti-ReDoS(Regular expression Denial of Service): Built-in policies to Anti ReDoS without configuration.
- CORS Enable CORS(Cross-origin resource sharing) for your API.
- URI Blocker: Block client request by URI.
- Request Validator
OPS friendly
- Zipkin tracing: Zipkin
- Open source APM: support Apache SkyWalking
- Works with external service discovery: In addition to the built-in etcd, it also supports Consul and Nacos, and Eureka
- Monitoring And Metrics: Prometheus
- Clustering: APISIX nodes are stateless, creates clustering of the configuration center, please refer to etcd Clustering Guide.
- High availability: Support to configure multiple etcd addresses in the same cluster.
- Dashboard
- Version Control: Supports rollbacks of operations.
- CLI: start\stop\reload APISIX through the command line.
- Stand-Alone: Supports to load route rules from local YAML file, it is more friendly such as under the kubernetes(k8s).
- Global Rule: Allows to run any plugin for all request, eg: limit rate, IP filter etc.
- High performance: The single-core QPS reaches 18k with an average delay of fewer than 0.2 milliseconds.
- Fault Injection
- REST Admin API: Using the REST Admin API to control Apache APISIX, which only allows 127.0.0.1 access by default, you can modify the allow_admin field in conf/config.yaml to specify a list of IPs that are allowed to call the Admin API. Also, note that the Admin API uses key auth to verify the identity of the caller. The admin_key field in conf/config.yaml needs to be modified before deployment to ensure security.
- External Loggers: Export access logs to external log management tools. (HTTP Logger, TCP Logger, Kafka Logger, UDP Logger)
- Helm charts
Highly scalable
- Custom plugins: Allows hooking of common phases, such as rewrite, access, header filter, body filter and log, also allows to hook the balancer stage.
- Plugin can be written in Java/Go/Python
- Plugin can be written with Proxy WASM SDK
- Custom load balancing algorithms: You can use custom load balancing algorithms during the balancer phase.
- Custom routing: Support users to implement routing algorithms themselves.

Get Started

Installation

APISIX Installed and tested in the following systems:

CentOS 7, Ubuntu 16.04, Ubuntu 18.04, Debian 9, Debian 10, macOS, ARM64 Ubuntu 18.04

Please refer to install documentation.
Getting started

The getting started guide is a great way to learn the basics of APISIX. Just follow the steps in Getting Started.

Further, you can follow the documentation to try more plugins.
Admin API

Apache APISIX provides REST Admin API to dynamically control the Apache APISIX cluster.
Plugin development

You can refer to plugin development guide, and sample plugin example-plugin's code implementation. Reading plugin concept would help you learn more about the plugin.

For more documents, please refer to Apache APISIX Documentation site

Benchmark

Using AWS's eight-core server, APISIX's QPS reaches 140,000 with a latency of only 0.2 ms.

Benchmark script, test method and process has been open source, welcome to try and contribute.
