Is NGINX a REST API?

Is NGINX a load balancer or API gateway?

I'm using NGINX as a load balancer with HAProxy for API Gateway (using API Gateway as backend server). It works well, but I'm wondering what it is. Is NGINX really a load balancer and if it is, is it used for the API Gateway?

NGINX is a web server, it will act as a reverse proxy for HTTP requests to other servers. The NGINX documentation does not mention API Gateway, but it does mention its ability to act as a web server, so it can certainly act as a reverse proxy. There are many different configurations that you could use with it depending on what you want it to do.

I am using NGINX as load balancer as well. In my case, I use NGINX as a reverse proxy (frontend) and a load balancer (backend). So, when you're saying NGINX is used for API gateway, I think it's a misunderstanding. The difference is, API gateway is a standalone application which is deployed separately. When you call it via HTTP, it receives a request and then make a call to another server or the service.

But in case of NGINX, you have to set it up first in order to receive requests, then, it would forward those requests to another server or the service. So, you don't have to set it up separately as it is already there. API gateway: it's a technology that acts as a service between a client and a backend server. In your case you have your web-app server behind it. It makes things like REST calls easier for the developer, since he/she can build the API without a framework specific to the back-end server.

Load balancer: it's a piece of software that distributes traffic to multiple servers, ensuring each server gets a fair share of traffic. It could be a single piece of software, or it could be part of a bigger system that performs load balancing and other tasks, like HAProxy. In your case you have two servers, one as a load balancer and the other as an API gateway.

Which API gateway is best for microservices?

In recent days I have been pondering over the use of API Gateways. I am looking for a solution that will let me create REST-based APIs for microservices and then let me route the calls to the different microservices.

For example, if I have a web service that just returns a string with Hello as a response, how can I use an API Gateway to route this request to a service that sends me a notification when I receive a message on my e-mail address. The service that will send me the message will be the microservice that will handle the message.

Does anybody have any experience with this type of scenario? I have tried to use a couple of solutions, but most of them are not what I am looking for. I am using Java, and Spring Boot is used in the back-end.

Thanks in advance! You can use CloudEndpoint (GAE) or a service like Apigee (AWS). Both of them support HTTP/2 and other modern features like CORS.

For your use case, CloudEndpoint would be a good fit. It is designed for building APIs that require API management.

Apigee would better suited if you're looking for a fully managed solution. You could have it deploy your application to GAE and manage it from there. You can also expose APIs to your users that will work like a regular web app, so you won't need to make any changes.

Can NGINX use for API gateway?

I would like to know if it is possible to use NGINX as an API Gateway for an application that does not have a web server. Currently, I am using Haproxy as an API Gateway and I have an Apache web server listening on port 80. I was thinking of moving to NGINX but I don't see how I could accomplish what I want.

My current architecture looks like this: You can use Nginx as an API gateway with minimal modifications. You need to configure nginx to listen to different ports. In the example below I've used 8080 as a proxy to forward requests to the web server.

After you configured your nginx you can test that the nginx listens to different ports by opening a browser and accessing or. You can read more about this here.
