OSv is a new, high-performance OS for virtual machines in the cloud. Designed to run one application per guest with minimal overhead, OSv eliminates important bottlenecks for NoSQL applications through improvements in memory management, network I/O, and scheduling. And many important bottlenecks for NoSQL applications are tunable on a conventional OS, but do not require tuning in the OSv environment.
OSv is fully stateless and can be configured at runtime with cloud-init or through a REST API, with zero configuration files. OSv offers unified tracing from the application layer through the JVM and the OS kernel. Attendees will learn how to boot Cassandra in one second, and create a simple cluster in a minute.
