This document explains VM Manager pricing details. You can also use the Google Cloud Pricing Calculator to estimate the cost of using VM Manager.

The entire VM Manager suite is charged as a single service at one flat rate per VM with an active OS Config agent.

You incur charges per the number of VMs that have an active OS Config agent as follows:

• To get started with testing in your environment a free tier is available. This free tier provides a monthly usage of 100 VMs per Cloud Billing account.
• Once the free tier is exhausted, for all VMs that have an active OS Config agent, each active agent is charged at a rate of $0.003 per hour per VM.

Note: In VM Manager limited functionality mode, you get a subset of features at no cost for unlimited number of VMs. For example, you can view OS policy assignments for VMs in the project, but you cannot create your own OS policy assignments or create patch jobs using VM Manager. For more information, see the workflow that installs Ops Agent and enables VM Manager in limited functionality mode. You can remove the limitations by enabling full VM Manager functionality using Google Cloud console.

The following table summarizes the units and formulas that can be used to determine the total charges.

The following examples are calculated in USD.

Example 1

If you are running 10 VMs in a 31 day month (744 hours) that have an active OS Config agent, using the formula from the preceding table, the calculations are as follows:

Free tier = 74,400 agent hours

Monthly usage = 744 * 10= 7,440 agent hours

Monthly usage is less than the free tier, so the adjusted monthly usage is 0 agent hours, and the total monthly cost is $0.

Example 2

If you are running 100 VMs in a 31 day month (744 hours) that have an active OS Config agent, using the formulas from the preceding table, the calculations are as follows:

Free tier = 74,400 agent hours

Monthly usage = 744 * 100 = 74,400 agent hours 

Monthly usage is equal to the free tier so the adjusted monthly usage is 0 agent hours, and the total monthly cost is $0.

Example 3

If you are running 700 VMs in a 31 day month (744 hours) that have an active OS Config agent, using the formulas from the preceding table, the calculations are as follows:

Free tier = 74,400 agent hours

Monthly usage = 744 * 700 = 520,800 agent hours

Monthly usage is greater than the free tier so the adjusted monthly usage is (520,800 - 74,400) = 446,400 agent hours. The monthly cost is calculated as follows:

Monthly cost = $0.003 * number of agent hours that exceed the free tier

= $0.003 * 446,400 = $1339.20
