Explanation:

1)Swift is the sub-project that delivers object storage. It provides similar functionality to Amazon S3 – more of which later. Cinder is the block-A2 component, delivered using standard protocols such as iSCSI.

2)Ephemeral storage, all IPs, RAM and vCPUs run in the OS memory. So, upon termination of the VM all the resources are freed.
