What is Kong API gateway?

Kong is a reverse proxy. It is a high performance, open source, multi-cloud distributed API gateway for HTTP, HTTP/2, WebSocket, TCP, gRPC, and other protocols.

Kong is a distributed network of servers responsible for load balancing, authorization, rate limiting, header caching, and many other functions. Kong is available as a container running as a single node or in a cluster.

This tutorial will show how to use Kong API gateway to receive JSON data from a PHP server and send it to the browser. You can build an API gateway using Kong or any other reverse proxy. Kong is easy to deploy and manage and has high performance. You can easily modify the API with Kong API Builder. If you are using Laravel or Symfony, you can also use the excellent Laravel Api Platform or Laravel Packages.

A reverse proxy provides a number of features. A reverse proxy receives requests from a client and sends them to a server on the backend. When the server returns a response to the client, the reverse proxy passes the response to the client.

In a typical example, a request from a client comes into the server. The reverse proxy receives the request and passes it on to a web server that sends a response to the client.

In a reverse proxy, the reverse proxy receives requests from a client and passes them to a web server that sends a response to the client. To better understand what a reverse proxy does, here is a diagram. The web server sends the response to the client. The reverse proxy receives the response and forwards it to the client.

How to make a reverse proxy? In this tutorial, we will use the Kong reverse proxy. Kong reverse proxy is open source and supports HTTP, HTTPS, WebSocket, TCP, gRPC, and other protocols. It is multi-cloud distributed and supports Kubernetes, Docker, Amazon Web Services, Google Kubernetes Engine, OpenStack, and Cloud Foundry.

Kong is easy to deploy and manage. You can add new Kong nodes to a cluster easily using the Kong CLI tool. You can deploy Kong to your Kubernetes cluster easily using the Kong Helm chart.

Let's build a simple reverse proxy using Kong.

What are the disadvantages of Kong API gateway?

We've all heard horror stories from developers, who had to go through a painful process of setting up and managing a new server just for hosting their endpoints. There were many difficulties and complexities involved, that would lead them to take a step back at this point, giving up creating an API and thinking this is going to be really hard.

One of the reasons for this behavior was that they didn't understand the true benefits of the API server. When you look at the world of web development, where every single piece of code has to go through a pipeline, you understand why the complexity and efforts needed to get rid of such hurdles have been high and that developers are willing to pay huge amounts of money to avoid them.

While you're still using legacy infrastructure to host your application and backend, don't forget about your front-end. Let's talk about the best way to do that, so we can create an architecture with high flexibility and maintainability. How an API server works. As an architecture, a good API server is going to serve two very important purposes: Create a consistent interface for all your clients to use. Enable easy REST-style API calls from other applications. You also need to make sure to use the latest technologies, like GraphQL for example, but these are details we will cover later in this article. First of all, how does it work? A simple API server works as a proxy between your API client and your back-end and can be configured in any variety of ways. It's the equivalent of a firewall in the internal network while HTTP requests coming from the Internet are blocked by it, internal HTTP requests from machines behind the firewall could get through. They will come as unauthenticated requests with empty headers, but then the API server will receive them on its side.

All this happens transparently to your clients, there won't be any visible difference in your UI and the request that a user sends. So your front-end application won't lose anything by this method. And from what we have seen, almost all the APIs that we have interacted with do actually have this type of infrastructure.
