Service Offerings
In this chapter we discuss compute, disk, and system service offerings. Network offerings are
discussed in the section on setting up networking for users.
9.1. Compute and Disk Service Offerings
A service offering is a set of virtual hardware features such as CPU core count and speed, memory,
and disk size. The CloudPlatform 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:
• CPU, memory, and network resource guarantees
• How resources are metered
• How the resource usage is charged
• How often the charges are generated
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, CloudPlatform emits usage records
that can be integrated with billing systems. CloudPlatform separates service offerings into compute
offerings and disk offerings. The computing service offering specifies:
• Guest CPU
• Guest RAM
• Guest Networking type (virtual or direct)
• Tags on the root disk
The disk offering specifies:
• Disk size (optional). An offering without a disk size will allow users to pick their own
• Tags on the data disk
