MicroStack speedily installs OpenStack on a single machine. Supported services are currently Glance, Horizon, Keystone, Neutron, and Nova.
The two general scenarios are a single-node install and a multi-node deployment.
Multi-node (or clustering) allows you to install MicroStack on several machines (“nodes”) and combine them together to provide a cluster. At this time the cloud roles that can be assigned to each node are control and compute. A MicroStack cluster can consist of a single control node and multiple compute nodes. Note that a control node also acts as a compute node.
Single-node is simply a single control node. It provides everything you need, including acting as a compute node.
Once you’ve deployed your desired scenario you can go on to perform native OpenStack operations such as importing boot images; creating keypairs, networks, and cloud flavors. See the OpenStack documentation.
