openstack
OpenStack is a free and open source cloud computing platform developed as a joint project of Rackspace Hosting and NASA. Users primarily deploy it as an Infrastructure as a Service (IaaS) solution. OpenStack cloud consists of many well know technologies like: Linux KVM, LVM, iSCSI, MariaDB (MySQL), RabbitMQ or Python Django.

OpenStack architecture overview:

  1. Horizon: web browser user interface (dashboard) based on Python Django for creating and managing instances (virtual machines)
  2. Keystone: authentication and authorization framework
  3. Neutron: network connectivity as a service
  4. Cinder: persistent block storage for instances based on LVM
  5. Nova: instances management system based on Linux KVM
  6. Glance: registry for instance images
  7. Swift: file storage for cloud
  8. Ceilometer: metering engine for collecting billable data and analysis.
  9. Heat: orchestration service for template-based instance deployment
