Summary


In this chapter, we looked at managing flavors, key pairs, instances, security groups, and floating IP addresses. Now that we have a running OpenStack instance, let's attach some virtual storage to it. A running instance's storage is ephemeral by design. This means that any data stored in the instance's local disk is lost upon the instance's termination. In the next chapter, we will attach a virtual block storage device to the running instance. This storage will persist after an instance that it is attached to is terminated.
