Erlang on Xen uses a new highly compatible Erlang VM - codenamed LING - capable of running as a Xen guest OS. We have been running Erlang on the bare virtual iron since 2011.
LING VM runs directly on top of Xen hypervisor. It does not require Linux or anything. This takes away numerous administrative, scalability, and performance issues.
To give you a hands-on experience with Erlang on Xen, we created a public Amazon Machine Image (AMI).
Today’s computing clouds, often advertised as elastic, are rather rigid. When compared to stiffness of iron, they achieve elasticity of wood. Rubber-like clouds are still on drawing boards.
Let us have a peek at the sketch of the future cloud we, the Erlang on Xen creators, have on our drawing board.
