OSv: Probably the Best OS for Cloud Workloads You've Never Heard Of
summary
OSv is a single-address-space library OS that packages an application and its libraries into a static-linked image that runs on KVM or VirtualBox, uses ZFS components, and exposes fewer drivers. Benchmarks show network- and JVM-heavy workloads running measurably faster than on Linux — up to roughly 25% on some I/O paths and as much as ~47% on certain Java tests — at the cost of requiring static linkage and no traditional process isolation. Docker-compatible images and a container registry model let OSv act as a high-performance backend for Cloud Foundry style deployments.
