Source: Announcing resource-based pricing for Google Compute Engine from Google Cloud Platform
By Paul Nash, Group Product Manager, Google Compute Engine
The promise and benefit of the cloud has always been flexibility, low cost, and pay-per-use. With Google Compute Engine, custom machine types let you create VM instances of any size and shape, and we automatically apply committed use and sustained use discounts to reduce your costs. Today, we are taking the concept of pay-for-use in Compute Engine even further with resource-based pricing.
With resource-based pricing we are making a number of changes behind the scenes that align how we treat metering of custom and predefined machine types, as well as how we apply discounts for sustained use discounts. Simply put, we’ve made changes to automatically provide you with more savings and an easy-to-understand monthly bill. Who doesn’t love that?
Resource-based pricing considers usage at a granular level. Instead of evaluating your usage based on which machine types you use, it evaluates how many resources you consume over a given time period. What does that mean? It means that a core is a core, and a GB of RAM is a GB of RAM. It doesn’t matter what combination of pre-defined machine types you are running. Now we look at them at the resource level—in the aggregate. It gets better, too, because sustained use discounts are now calculated regionally, instead of just within zones. That means you can accrue sustained use discounts even faster, so you can save even more automatically.
To better understand these changes, and to get an idea of how you can save, let’s take a look at how sustained use discounts worked previously, and how they’ll work moving forward.
Okay. Now, what if you used different machine types?
With resource-based pricing, we no longer consider your machine type and instead, we add up all the resources you use across all your machines into a single total and then apply the discount. You do not need to take any action. You save automatically. Let’s look at the scaling example again, but this time with resource-based pricing.
And because resource-based pricing applies at a regional level, it’s now even easier for you to benefit from sustained use discounts, no matter which machine types you use, or the number of zones in a region in which you operate. Resource-based pricing will take effect in the coming months. Visit the Resource-based pricing page to learn more.
