Python virtualenv or venv are the short forms of virtual environment.
Virtualenv is useful for different projects with unique requirements for each of them, like versions of python or at least different versions of Python libraries.
So they run parallel on a same system in separated from each other environments without any conflicts between them.

WireGuard(WG) aims to provide a VPN that is both simple and highly effective.
Also to make a really good alternative technology to the existing like IPsec or OpenVPN.
WG is a free and open-source software application and communication protocol that implements virtual private network (VPN) techniques to create secure point-to-point connections in routed or bridged configurations.
I tried WG in a complex high availability datacenter setup and replaced a couple of existing OpenVPN connections with WG.
The result was performant and simple at once.

AWS EC2-instances can be also automated and this can happen at the creation point of each single instance.
