If the instance the user wants to start is not the project's first, a subnet and a VLAN must have already been assigned to the project; therefore the system needs only to find an available IP address within the subnet and assign it to the new starting instance. If there is no private IP available within the subnet, an exception will be raised to the cloud controller, and the VM creation cannot proceed. -.. todo:: insert the name of the Linux bridge, is it always named bridge?

Cloud computing can help with large-scale computing needs or can lead consolidation efforts by virtualizing servers to make more use of existing hardware (and possibly release old hardware from service.) People also use cloud computing for collaboration because of the high availability through networked computers. Productivity suites for word processing, number crunching, and email communications, and more are also available through cloud computing. Cloud computing also avails additional storage to the cloud user, avoiding the need for additional hard drives on your desktop and enabling access to large, huge data storage capacity online in the cloud. + |
