Question

network hardware

Good afternoon, colleagues.
The option of separating the app server and db server into different data centers is being considered. Where db is planned to be placed at the enterprise, and under the app server, respectively, select a service provider.
What is the maximum speed of the channel in Moscow is possible between them? Is it somehow consciously possible to choose data centers connected by a 1-10gbit channel?
To be honest, I don’t know how to formulate the question correctly, but I think from the description it’s clear what I want to understand.

Answer 1

If the dough is enough.
