A quick approach for cost monitoring on Kubernetes
How to get cost insights about the projects running on Kubernetes without introducing any extra components
This article presents an approach to approximate the costs a specific project/team generates on Kubernetes, based on the ratio of resources allocated to them vs. the total resources in the cluster.
One of the results we expected to achieve with this transition was a significant cost reduction. With Kubernetes, all our projects (big and small) would be able to share the same underlying infrastructure and thus leave less room for idle resources.
Before the transition to Kubernetes, each team could go to the AWS Cost Explorer and see how much money each of their projects was spending. Naturally, we wanted to maintain that level of visibility.
The challenge with Kubernetes is that, because different pods share a pool of resources, attributing a part of the total cost to a specific project (or team, or environment, …) is not trivial. At the moment, the built-in budgeting tools of most cloud platforms I know (AWS in our case) do not provide a straightforward way to explore these costs either, so we were left with two alternatives:
We briefly considered option (1), but decided to hold off on adopting a solution that would require extra maintenance and/or procurement.
What follows is our implementation of option (2): A low-hanging-fruit approach to cost monitoring on…
