Zerotier
ZeroTier is a smart programmable Ethernet switch that enables all networked devices, virtual machines (VMs), containers, and applications to communicate as if they are all located in the same physical data center or cloud region. It creates a virtual network that spans across different physical locations, simplifying the management and security of network communications. ZeroTier is particularly beneficial for IT professionals and organizations looking to streamline their network infrastructure and enhance connectivity across distributed environments.
