apisix-ingress-controller VS Nginx

This post shows how to implement it with Apache APISIX.

APISIX Ingress Controller is a tool focused on API management, offering high performance and flexible configuration options. If you require more complex routing rules, rate limiting, circuit breaking, and other advanced features, APISIX Ingress Controller may be a better choice. It provides a rich plugin system, allowing integration of plugins through APISIX Ingress CRD using declarative configuration to handle authentication, authorization, monitoring, logging, and other functionalities. This enriches the capabilities of APISIX Ingress Controller and simplifies configuration.

In this post, I'd like to describe how to fix some of them via the Apache APISIX API Gateway.

In the era of digitization, the availability and stability of services are crucial for the success of enterprises. As a key component of microservices architecture, the API gateway plays a significant role. APISIX, an open-source API gateway platform, ensures the continuity and stability of services through its health check mechanism.

Next February will mark the two-year milestone that I'm working for: API7.ai on Apache APISIX. I'm still very pleased about both. It allows me to do things I like a lot, such as writing posts and giving talks.

In early 2021, I started to work on the Apache APISIX project. I have to admit that I had never heard about it before. In this post, I'd like to introduce some Apache projects that are less well-known than HTTPD or Kafka.

Apache APISIX is an API Gateway, which builds upon the OpenResty reverse-proxy to offer a plugin-based architecture. The main benefit of such an architecture is that it brings structure to the configuration of routes. It's a help at scale, when managing hundreds or thousands of routes.

API resilience is about building robust APIs that can withstand a variety of challenges, ensuring that they continue to function effectively. API Gateways play a key role in this, acting as the entry point for external requests and managing the communication between different services by taking into account common API resilience patterns. One of the popular open-source API Gateways, Apache APISIX, provides a variety of features to enhance the resilience and robustness of APIs. In this article, we will explore 10 common API resilience design patterns and how they can be implemented using APISIX.

Yeah, unless I'm looking at it wrong, there doesn't seem to be any meaningful difference between 1.25.5 and 1.26.0:

However, it's very unlikely that .NET developers will directly expose their Kestrel-based web apps to the internet. Typically, we use other popular web servers like Nginx, Traefik, and Caddy to act as a reverse-proxy in front of Kestrel for various reasons:

Have a look at:

https://github.com/nginx/nginx/blob/master/src/http/modules/...

It's got the whole checklist: nginx idiosyncratic module system, inline parsing, custom utf conversion, buffer preallocation and adjustments, linked lists, comments about side effects of custom allocator, and probably other things.

It's not easy to deal with source like that and any serious improvement to that area would effectively be a rewrite anyway.

Since anything doing work in nginx is a module anyway, it wouldn't even have to be a full rewrite in one go.

According to this article, nGinx is being used to serve 34% of all websites in the world. I checked out who's contributing to nGinx, and just like I thought, the project has 8,208 commits, and 5,366 of those commits was made by 2 software developers; igorsoev and mdounin.

Nginx + Roadrunner (fcgi mode)

Apache’s mod_fastcgi’s last commit was 2 weeks ago:

https://svn.apache.org/viewvc/httpd/httpd/trunk/

It’s a fork of what you linked (and was more popular afaik back when fastcgi was state of the art, and apache was the undisputed champion of web servers).

These days, nginx has more market share than apache, and its fastcgi module is one of the more recently updated ones in its source tree (5 months vs multiple years):

https://github.com/nginx/nginx/tree/master/src/http/modules

If I was going to build an embedded web server, I’d start with nostd rust, probably with though axum + tokio, since thats already memory safe-ish.

If I needed fastcgi for some reason (dynamically loadable endpoints, or os-level isolation), there are at least four implementations of fastcgi for it. No idea if any are decent though.

APISIX is an API Gateway. It builds upon OpenResty, a Lua layer built on top of the famous nginx reverse-proxy. APISIX adds abstractions to the mix, e.g., Route, Service, Upstream, and offers a plugin-based architecture.
