How to merge servers?

Question

Software and Internet Services

Probably a stupid question. How to connect servers? That is, I have a couple of ancient machines and a program that is installed on the server, but 1 server does not pull it and I need to connect a couple more. Not just add RAM, but also processors. The program does not know how to work with clusters.

Answer 1

Your task sounds very abstract, so you will get the most abstract and, most likely, incomprehensible answer. Let's think about how you can solve your problem:
1. "a program that is installed on the server but 1 server does not pull it and you need to connect a couple more" - it is not clear from this expression, it basically "does not pull" or "does not pull on your server" . Can a conditionally "cool server" run it so that it works correctly? If so, then the easiest way would be to buy / rent a server with the necessary hardware.
2. Your "program" can successfully process one task, but there are too many tasks, it cannot cope with the data flow.
This is a different case. For such a case, you can write some kind of balancer that distributes tasks to instances of your application. For example: you have a lot of video files that are encoded through ffmpeg into the required formats. Then one of your applications receives files, saves them and then adds them to the queue, and your second transcoder application, which takes them from the queue to work, is running on n servers.
3. Your program cannot perform 1 task on 1 server of any configuration and capacity. Then there is an option to rewrite it, adding parallelization, but not the fact that this will increase its efficiency or feasibility. Not all algorithms are well parallelized.
Describe the problem better, maybe not everything is so scary
