This document discusses OSv, an operating system designed for cloud workloads. Some key points: - OSv is a unikernel that provides a lightweight virtualized environment optimized for individual applications and services. It aims to improve performance over traditional virtual machines. - OSv uses application-specific static linking to include only necessary libraries, resulting in very small and fast to load "VM images". It can run existing Linux applications and services. - Early tests show OSv providing significant improvements over Docker in network throughput and latency for network-intensive applications. It also allows new approaches to memory and process management. - The ultimate goals of OSv include replacing virtual machines, further optimizing container-
