[Cinder] (born from nova-volume) The goal of the Cinder project is to separate the existing nova-volume block service into its own project.
[Swift] Swift is a highly available, distributed, eventually consistent object/blob store. Organizations can use Swift to store lots of data efficiently, safely, and cheaply. Cinder is an project to leverage different backend storage pool as "block devices" for Nova instance . Swift is an object storage . The way to keep files (objects) eventually consistent. There're many differences between Cinder and Swift. In a short summary , swift is not that good for very fast real-time I/O . And the object contents is unstructured . Looks like a box but you can not open it. Once you modify the content , the whole object will be a new one box. Cinder provides user a pool for creating volume disk which present as block level driver. If you ask me a question : Could swift's container be an instance's virtual disk? The answer is "YES" but in high risk.
