Launching an Instance in Openstack!

Ever wondered of hosting your own cloud in your own machine or on top of public cloud & launching an instance in it. A small note: before launching any instance or to do any operation, you should be in the demo or admin role in CLI mode. There are 3 ways available to spawn an instance in Openstack:Through WebUI: This service of WebUI is provided by the Horizon service in Openstack.

This service is very easy to use, that is why I am not covering instance spawning through this service in this article. Through Command Line Interface (CLI): The service which is used for computing in Openstack is known as “Nova”, this is the service which launches an instance with the help of other services which are “Cinder”, “Glance”, & “Neutron”, they are used for block storage, image management, & network services respectively.
