Ubuntu on public clouds

The most popular operating system across public clouds is Ubuntu, because we work closely with major cloud operators to optimise the kernel and system for their infrastructure, speed up security updates and minimise the cost of network or storage for users by default.

  • Canonical guarantees the consistency, security and performance of Ubuntu on public clouds
  • Enterprise-grade commercial support is available
  • Twice as popular on the Amazon cloud as all other operating systems combined *
