Instances are nothing but virtual machines inside the cloud. We can launch instance using images, volumes or by using snapshots of previous instance.
After login, goto Project → Compute → Images where all the uploaded images are present. User can create several instances from single image.
After creating specified image we need to create specified volume, goto Project → Compute → Volumes → Create Volume. To enable persistent storage we need volume which is block storage device attached to instance.
Goto Project → Compute → Instances → Launch Instance
Specify Instance Name, Availability Zone and Count of instances.
In Source, We need to select Boot Source from available images and volumes.
Flavors manage the sizing for compute, memory and storage capacity of instance.
Networks provide communication channels to the instance in cloud.
There are some additional options such as Network Ports for extra communication channels, Security Groups and Server Groups for launching instance in specified group, Key Pair to allow SSH for newly created instance, Configuration, Scheduler Hints and Metadata.
Then click on Launch Instance button and we can see Active instance in system.
