"CoreOS is a Linux distribution that has been rearchitected to provide features needed to run modern clustered infrastructure stacks. The strategies and architectures that influence CoreOS allow companies like Google, Facebook and Twitter to run their services at scale with high resilience. We've implemented them correctly so you don't have to endure the slow, learn-as-you-go infrastructure building process.
CoreOS can run on your existing hardware or on most cloud providers. Clustering works across platforms, making it easy to migrate parts of your gear over to CoreOS, or to switch cloud providers while running CoreOS."
