What is the difference between API gateway and proxy gateway?

How to use API gateway as a proxy?

I am using API gateway as a proxy in our system, since now we face a problem, when we call some services, such as salesforce api, in my case.

We are calling the service from our server which is a public IP, and API gateway will call it with his internal IP. The problem is we are facing timeout in some cases.

Any ways, to prevent this problem we do have a solution. We make request with api gateway and make that request for the public IP to our public IP in the same time. We hope this will solve the problem. But that also have an issue. It won't work with our customer. Can you think of any way to solve this?
Use a LoadBalancer in API Gateway as follows: Set up VPC on EC2 or GCP. Configure load balancer (Amazon doesn't require EC2 instances). Add Security Groups to each EC2 instance to allow inbound outbound traffic in-between instances. Create a new VPC with a public and private subnet with two EC2 instances in each. Make sure the private IP of each EC2 instances is allowed by your Security Group to be used from outside the VPC.

Create API Gateway. Create an API and map HTTP to HTTPS using TLS to your security group. By default, any request not mapped to HTTPS fails in HTTP, therefore allowing requests to reach an application behind the LoadBalancer. Hope it helps!

How to call rest API with proxy?

I need to call a rest API through proxy.

I am using RestAssured but I need to authenticate first and set a proxy. I can't find any examples. Can anyone please guide me?
Thanks in advance. The Rest Assured API was designed to be used through a proxy. This is the reason you can't find any examples of how to use it, because that's how it was designed to be used.

To authenticate with a proxy, add the property proxyUserInfo and proxyPassword to your application's properties file. The example code below would look something like this: RestClientBuilder rb = RestClientBuilder.create(); rb.setProxy("proxyhostorurl"); rb.setProxyUserInfo("proxyusername"); rb.setProxyPassword("proxypassword"); RestAssured.given().auth("username", "password").get("/api-url");
When you are done, use the same RestClientBuilder to create the Rest Client. The RestClientBuilder is thread safe and will allow you to reuse a single object if you need to run multiple requests concurrently.

What is the difference between API gateway and proxy gateway?

When I started reading about API gateway and proxy gateway, I couldn't understand the difference between these two, I came across many blogs and posts but most of them are vague and non-specific.

I know that API gateway is a proxy for frontend and Proxy Gateway is a proxy for backend, but whats the difference between them? Is there any practical example of usage of these two

In short, an API gateway is the HTTP/HTTPS server that your REST API is running on, whereas a proxy gateway is a proxy that is run on a server. This means that an API gateway is the actual server that your REST API is running on. An example would be running the API gateway on a server at: Whereas a proxy gateway is something like a reverse proxy that is run on a server that is accessed via. This means that the reverse proxy in the case of an API gateway, is the reverse proxy that runs on the same server as the REST API that we are running. In this case, it is a reverse proxy running on the same server as the REST API that is called the proxy gateway.

The benefit of the proxy gateway is that it is a more robust reverse proxy than an API gateway because the API gateway is running the REST API. What this means is that the REST API may be compromised if an attacker gains access to the REST API's endpoint, whereas with a proxy gateway, it is only the proxy gateway endpoint that is compromised and not the REST API. The proxy gateway also provides a more secure reverse proxy than the REST API because the proxy gateway runs the REST API (and thus has the same code path), so it is much more difficult to attack the proxy gateway than the REST API. An example of using a proxy gateway is that you are running a reverse proxy for your REST API.
