The BEAM virtual machine is the most commonly used machine for executing Erlang. Note that the link above is somewhat old, and does not describe the BEAM in use today. But it is still a nice description of a virtual machine. Also note that there has existed other VMs for Erlang, most notably the JAM.
The EVM (Ethereum Virtual Machine) is the virtual machine that underpins the Ethereum network.
