What software should be used to describe the interaction of software in an organization?

Question

Software and Internet Services

The organization has many servers, each running several services.
A service can be understood as: a database, an application server, a 24x7 process, in general, any server software.
We need some kind of tool that would allow us to describe the scheme of interactions of all services with each other.
So that you can poke at the server and see what is spinning on it, how it is connected with other servers and services on them.
Example, the server is bad, you need to restart it, and at the same time you need to know that it will stop working if this server drops out of the network, or something else needs to be rebooted.

Answer 1

You need something interactive that allows you to describe connections, make reports.
