Ideally, each individual containers is directly addressable by every other container within a virtual private cloud. The Fan overlay network for containers expands address space 250x on each container host. Both feature incredible density – Canonical has demonstrated thousands of full Ubuntu machines hosted on a single server using LXD. “Containers provide dramatically improved performance and density over traditional hypervisors like ESX and KVM,” said Mark Shuttleworth.Ĭontainers come in two complementary forms - full machine containers from LXD and application-centric containers such as Docker or Rocket. The Fan enables cloud users to grow the number of Docker and LXD containers they can address in a single cloud environment. Today, Canonical introduces the Fan overlay network system in Ubuntu in test images for Amazon Web Services and Google Compute Engine, delivering the fastest and most scalable address expansion mechanism in the container world.
