Snakes on a cloud: the OpenStack project
summary
OpenStack begins as a 2010 merge of Rackspace Cloud Files and NASA Nova and now has about 100 developers and three releases in its first year. Core components are Swift in production (object storage using DHT “rings” with three replicas via rings and per-account/container listing rings), Glance (image registry/backends), and Nova (modular compute used in NASA Nebula). Implementation uses Python, libvirt, eventlet, RabbitMQ and SQLAlchemy, follows share‑nothing and async design, enforces PEP8 and unit plus smoke testing, and moves to six‑month releases.
