OpenStack is an operating system that controls hardware resources such as compute, storage and networking. It allows the creation and management of virtual machines, which act like separate individual machines, by emulation in software. This allows users complete control over their computing environment, from choosing an operating system to software installation and configuration. This flexibility facilitates diverse usage cases, from hosting websites and to create a computing cluster by configuring multiple VMs to work together. See official documentation [http://docs.openstack.org/ http://docs.openstack.org/] for more details about OpenStack. | |||
This page describes how to perform common tasks which might be encountered while working with OpenStack. | |||

Volumes provide storage which is not destroyed when an VM is terminated (unless explicitly told to do so). On the Compute Canada clouds volumes use Ceph storage (see [https://en.wikipedia.org/wiki/Ceph_(software) https://en.wikipedia.org/wiki/Ceph_(software)] ) which has a 3X replication factor which provides safety against hardware failure. See OpenStack documentation for further details about volumes [http://docs.openstack.org/user-guide/common/cli_manage_volumes.html http://docs.openstack.org/user-guide/common/cli_manage_volumes.html]. | Volumes provide storage which is not destroyed when an VM is terminated (unless explicitly told to do so).
