<title>Compute and Disk Service Offerings</title>
|
||
<para>A service offering is a set of virtual hardware features such as CPU core count and speed, memory, and disk size. The &PRODUCT; 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:</para>
|
||
<itemizedlist>
|
||
<listitem><para>CPU, memory, and network resource guarantees</para></listitem>
|
||
<listitem><para>How resources are metered</para></listitem>
|
||
<listitem><para>How the resource usage is charged</para></listitem>
|
||
<listitem><para>How often the charges are generated</para></listitem>
|
||
</itemizedlist>
|
||
<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, &PRODUCT; emits usage records that can be integrated with billing systems. &PRODUCT; separates service offerings into compute offerings and disk offerings. The computing service offering specifies:</para>
|
||
<itemizedlist>
|
||
<listitem><para>Guest CPU</para></listitem>
|
||
<listitem><para>Guest RAM</para></listitem>
|
||
<listitem><para>Guest Networking type (virtual or direct)</para></listitem>
|
||
<listitem><para>Tags on the root disk</para></listitem>
|
||
</itemizedlist>
|
||
<para>The disk offering specifies:</para>
|
||
<itemizedlist>
|
||
<listitem><para>Disk size (optional). An offering without a disk size will allow users to pick their own</para></listitem>
|
||
<listitem><para>Tags on the data disk</para></listitem>
|
||
</itemizedlist>
