Metered Resources – Setting up Unit Multiplier and Monthly Unit Price

Cloud Assert Usage & Billing for Windows Azure Pack

Metered Resource Pricing Setup Wizard (sample):


Step 1: Determine the WAP Usage Resource and its unit (Raw Usage unit)

Each WAP Resource’s Raw Usage is expressed in different units. This unit is decided by the Resource Provider that generates that usage. Cloud Assert Usage & Billing product depends upon these Raw Usage values, to calculate the bill and invoice of each customer.

One might need to refer to the Resource Provider’s documentation to know this unit.

Example WAP Resources:

#

Metered Resource

Units in which raw usage is returned by WAP

1

systemcenter

Virtual Machine

CPUAllocationCount-Max

Number of CPUs

2

systemcenter

Virtual Machine

MemoryConsumed-Max

Mega Bytes (MB)

3

systemcenter

Virtual Machine

CrossDiskSizeAllocated-Average

Bytes

 

Step 2: Set the Unit Multiplier

Decide the units in which to charge the customers and accordingly set the Unit Multiplier. This Unit Multiplier is multiplied with the Raw Usage, to generate the resulting units (Billable Units) upon which pricing is calculated.

Calculated Units or Billable Units = Raw Usage value * Unit Multiplier

For instance, if the Raw Usage unit is expressed in Mega Bytes, and if you decide to setup the Monthly Pricing based on Giga Bytes, then the Unit Multiplier will be 1/1024 expressed in decimals.

Examples:

Step 3: Monthly Unit Price - Set the price per month based on above units

Monthly Unit Price is the price equivalent for usage of ‘1 unit / hour’ of usage for 720 hours (24 hours * 30 days). Based on this value, Hourly Unit Price is calculated internally by Cloud Assert Usage & Billing product and used to calculate the net cost of a customer’s per hour usage of a WAP Resource.

Usage Cost @ a hour = [Billable Units @ that hour] * [Hourly Unit Price]

Usage Cost @ a hour = Raw Usage value * Unit Multiplier * Monthly Unit Price / 720

Example Price setup:

Cost Calculation examples

Example 1: Compute Units or Total Count

In the below table, Hourly Unit Price is calculated considering Monthly Unit Price as 10 MYR/ 1 Unit.

Example 2: Bytes / MB / GB

In the below table, Hourly Unit Price is calculated considering Monthly Unit Price as 40 MYR / 1 GB.

From the rows (1) and (2), we can observe that even when ‘Calculated Hourly Units’ and ‘Hourly Unit Price’ are different, the ‘Calculated Hourly Price’ stays same if the usage is same.
