What is the difference between API gateway and load balancer?

Is load balancer same as reverse proxy?

I have a web application server that has multiple instances. I want to use reverse proxy to access the application from the internet. Should I use a load balancer like HAProxy as the reverse proxy?

The load balancer and the reverse proxy are two different things. The load balancer is a device that receives traffic from the internet and distributes it to multiple servers. The reverse proxy is a device that receives traffic from the internet, and then forwards it to the application server. So, in your case, you'd need to use a load balancer in front of the application server, and then have the reverse proxy on the application server. However, HAProxy is a load balancer. It is a very good load balancer, but it is not a reverse proxy. I believe that you can use HAProxy as a reverse proxy, but I'm not sure if it is a good idea.

What is the difference between API gateway and load balancer?

API gateway is a web proxy that sits in front of your microservice(s) and can call them, and can also call other services. API gateway is not a load balancer.

API gateway is a web proxy that sits in front of your microservice(s) and can call them, and can also call other services. Load balancer is a software or hardware device that distributes client requests across a pool of server machines (also called nodes) based on a weighted or round robin algorithm. Load balancers can use any kind of protocol like TCP/IP, HTTP, or SSL. Load balancers can be fronted by anything from an appliance to a corporate network to a dedicated server. Load balancers can use a wide variety of algorithms for distributing requests, including round robin, least connections, least busy, weighted least connections, weighted least busy, and weighted round robin. Load balancers can use a wide variety of protocols, including HTTP (the usual web request protocol), HTTPS (secure web request protocol), and other protocols like TCP and UDP. Load balancers can use any kind of router, including hardware-based routers and software-based routers, depending on the load-balancing algorithm. Load balancers can use a wide variety of protocols for routing, including IP, UDP, and TCP.

What is the difference between API gateway and proxy?

I am using aws lambda for API gateway and I am not sure ? API Gateway is a Layer 7 application, that is, it makes decisions based on the contents of the request message, as opposed to the HTTP protocol layer, which is Layer 5. Proxy is a function of the application layer -- it sits between the web server and the application. It will inspect the request and determine if it should be proxied to the web server, or if it should be passed on to the application.

An API gateway is a cloud service that provides a general purpose API management layer. A proxy is a software component that intercepts a request and adapts it to a new request structure. The API gateway contains a proxy that could be used for most of the applications. By default, API gateway has the proxy enabled.

The proxy could be disabled by the user. If you want to use the API gateway for API, you should disable the proxy in the API gateway. In this case, API Gateway could only provide API management and not the proxy. If you want to use the proxy for API, you should enable the proxy in the API gateway.

Using web application on Spring Boot with Java backend and Express for node

Sorry but: No1, No2. I reached to conclusion with only: Rose May from Spring Boot with java backend (micro service) and Express.js on AWS, just as they are built-in as module within the Spring Initial Rade class.

Thank you. The flask-socketio example is a typical example of linking two, seemingly completely different services together. But when it comes to VPC integration, the nature of the two is the exact same: Flask is running in the EC2 instance and provides request routing for external traffic. Flask-socketio is running in Amazon EC2 Container service and provides a WEB SOCKET interface for the instance. When you review AWS API Gateway itself, it's like a typical static request router. Mostly you tell an API what you (or your clients) are willing to accept, and even if someone in the middle tries to communicate between two different instances or technologies in an incompatible manner, they won't be able to if they don't know the URL parameters. If you want to communicate between two technologies, there is a WSDL that outputs the parameters.

If you want to get a web frontend beyond just HTTP requests (and control it rather than just exposing it), you should be looking into a reverse proxy rather than API Gateway, as there's no requirement for a VPC for a reverse proxy.
