A service offering is a set of virtual hardware features such as CPU core count and speed, memory, and disk size. The CloudStack administrator can set up various offerings, and then end users choose from the available offerings when they create a new VM. A service offering includes the following elements:
|
||
</div><div class="itemizedlist"><ul><li class="listitem"><div class="para">
|
||
CPU, memory, and network resource guarantees
|
||
</div></li><li class="listitem"><div class="para">
|
||
How resources are metered
|
||
</div></li><li class="listitem"><div class="para">
|
||

|
||
</div></li><li class="listitem"><div class="para">
|
||
How often the charges are generated
|
||
</div></li></ul></div><div class="para">
|
||
For example, one service offering might allow users to create a virtual machine instance that is equivalent to a 1 GHz Intel® Core™ 2 CPU, with 1 GB memory at $0.20/hour, with network traffic metered at $0.10/GB. Based on the user’s selected offering, CloudStack emits usage records that can be integrated with billing systems. CloudStack separates service offerings into compute offerings and disk offerings. The computing service offering specifies:

A service offering can be deleted. If it is no longer in use, it is deleted immediately and permanently. If the service offering is still in use, it will remain in the database until all the virtual machines referencing it have been deleted. After deletion by the administrator, a service offering will not be available to end users that are creating new instances.
