What is the best API Gateway for Microservices?

As entry points to applications, API gateways are an essential part of any microservices architecture. The right API gateway for a microservices architecture will depend on the specific needs of your application.

In this article, we’ll explore some of the best API gateways for microservices. Tyk, Kong Gateway, Goku, Apache APISIX, and Ocelot are our top recommendations.

Let’s have a closer look at each of these API gateways to help you pick the right one:

1. Tyk

If flexibility and practicality are qualities you’d consider when choosing an API gateway, Tyk should the go-to option. As an enterprise-ready and open-source gateway that gives you the option of using it as a managed or self-hosted solution, you can be sure this one will meet your needs.

What’s more, Tyk is designed to be highly scalable so that it can handle large numbers of requests without any issues. Simply put, Tyk is the best API gateway for Microservices if you’re looking for a gateway that is flexible and practical.

Some of Tyk’s top features include:

  • Backward compatibility
  • Version control
  • Authentication (to enhance security)
  • Notifications and events
  • GraphQL as standard
  • Mock out APIs
  • Quota and rate limiting
  • Detailed monitoring and analytics
  • And more

2. Kong Gateway

Kong Gateway is another popular open-source API gateway that is suitable for microservices. It’s easy to use and comes with a wide range of plugins that can be used to extend its functionality.

As a cloud-native gateway that is built upon a lightweight proxy, you are guaranteed scalability and security. In addition to scalability, another assurance that you’ll have when using Kong is great latency performance.

You can expect the following top features from Kong:

  • Plugin extendability
  • Traffic control
  • Transformations
  • Authentication
  • Server-free performance
  • Analytics
  • Logging

3. Goku

As EOLINK Inc.’s umbrella project, GOKU API gateway is a newer option that is inspired by the microservices architecture. This Golang-based microservice gateway makes it easier to achieve service orchestration, API access control, high-performance dynamic routing, and more.

One thing that you are going to like about Goku is the graphic interface and the plug-in system. That’s in consideration that these two entities go a long way in making the configuration of your gateway much easier.

In addition to the standard features, you can expect additional features such as:

  • Logging
  • Clustering
  • Alerting
  • Hot updates
  • And more

4. Apache APISIX

Apache APISIX is yet another open-source API gateway that wasn’t open-source at first. According to the experts behind this project, Apache APISIX was born to solve the challenges that are associated with cloud-native and microservices.

One of the notable things about this gateway is that it is based on etcd and Nginx. In addition to the standard features, you also get the following:

  • Dynamic routing
  • Plug-in hot loading
  • Canary release
  • Configuration rollback
  • And more

5. Ocelot

The most outstanding aspect of Ocelot is that it is a .NET API gateway. This API gateway is designed to be best compatible with .NET in running microservices. That way, it can support microservices or a service-oriented architecture that requires a unified point of entry into a system.

Keep in mind, however, that the API can work even with HTTP. It’s also easy to use on platforms that ASP.NET supports.

The main features that you get from Ocelot are standard features, mainly:

  • Routing
  • Rate limiting
  • Authentication
  • Caching
  • And more

There you go,

These are the top five API gateways that we believe can best help you with your microservices.

As always, it’s important to carefully consider your needs before settling on one particular gateway. That way, you can be sure that you’re getting the best possible solution for your project.
