API Gateways: Advantages, Drawbacks, and More


As a business owner, you probably keep hearing about “API gateways”. They’re a big trend, with countless businesses implementing API gateways into their systems. From the outside, though, you might be a little confused about what exactly API gateways are, so you should use this guide to supplement your API gateway knowledge and understand how they work. 

This post will begin by explaining what an API gateway is to you. After that, you can read about the advantages and drawbacks that come with using API gateways. Once it’s all said and done, you’ll be free to decide whether an API gateway is right for your business — which it almost certainly is!

What is an API Gateway? 

An API gateway is the smart little server that sits between the client and microservices endpoints. 

In a nutshell, the API gateway will complete automated tasks for you, such as processing the API requests that come in. If you have a popular application that a third-party app wants to communicate with and gain information from, the API gateway will make sure that the third-party app only gets access to the information it needs and nothing else. 

Now, let’s discuss one of the many API gateway examples. When you use an app and choose the ‘Sign in with Facebook option, the app will communicate with Facebook to get the relevant information it needs (such as your name and account details). The API gateway will then stop the third-party app from getting any additional information from Facebook that it doesn’t need, ensuring maximum security.
