Canonical says that LXD, its container-based virtualization solution for Ubuntu, is now the “world’s fastest hypervisor” with the release of Linux Containers (LXC) version 2.0, which appeared a few days ago.
The ability of containers to provide performance improvements over traditional virtualization is one of the main selling points of LXD, as well as competing open source container platforms like Docker. Canonical is playing up that angle hard in the wake of the LXC 2.0 release. Ubuntu founder Mark Shuttleworth says that the current version of LXD represents “the biggest change in Linux virtualization in 10 years.”
What is LXD (“lex‐dee”)?
Imagine you could launch a new machine in under a second, and that you could launch literally hundreds of them on a single server. Now, imagine hardware‐guaranteed security to ensure that those machines can’t spy on one another. Imagine you can connect them separately and securely to networks. And imagine that you can run that on a single node or a million, live migrate machines between those nodes, and talk to all of it through a clean, extensible REST API.
By combining the speed and density of containers with the security of traditional virtual machines, Canonical’s LXD is the next‐generation of container hypervisor for Linux.
