Erlang on Xen: Redefining the Software Stack

on YouTube ↗26m

" summary

A reimplemented Erlang VM runs directly on Xen with 4-5 ms startup and can spawn at least 10 uVMs/sec per physical node, is largely OTP-compatible but requires porting of OS-bound libraries, and offers a public build service and demos. Architectural rules insist on no guest OS, services oblivious to physical node boundaries, a shared auto-scalable fabric, computation placed near disks to cut network I/O, parent-driven node configuration and automated administration; design favors many single-CPU VMs — SMP is abomination.
