Great series of articles I saw a few months ago and now I want to comment on how to create an API from a cluster with 5 Raspberry PIs interconnected. A lot of experience but simple execution. I quickly define some of the terms for those who are not developers:
An API is a call, usually to a url or web address, from which we can execute a series of actions and receive a response in return.
A cluster is a set of computers that connect to each other for further processing thanks to their CPU and sometimes even using the power of the GPU.
Docker is a container-based technology that will set up a development environment without "messing up" your system too much.
I'm cheering up again with the blog. Let's see if I write long and hard about it. But now I leave you with the links of the article.
