Let's say I have 2 web servers. Both of them just installed Node.js and is running a website (using Express). Pretty basic stuff.
How can Server-A tell Server-B to execute a function? (inside node.js)
Preferably...is there a npm module for this that makes it really easy for me?

To call a function inside another function, define the inner function inside the outer function and invoke it. When using the function keyword, the function gets hoisted to the top of the scope and can be called from anywhere inside of the outer function.
Each node is with one type of server. It shares the workload across servers on multiple nodes according to the requirement. This major benefit for the horizontal cluster is that the users are allowed to use the application if one node encounters the failure.
Node. js is a server-side, packaged software that contains predefined processes to accomplish specific tasks. As a server-side runtime, every Node. js process is executed on a server; essentially working on the backend aspect of an application to manage data.

You can use one of the RPC modules, for example dnode.
