Chargeback in cloud computing means billing each internal team for its share of the cloud bill. Your company pays the provider’s invoice, then charges each team through its own accounting system.
An example from AWS
A showback report says the infrastructure engineering team was responsible for $X of AWS spend last month. Cloud chargeback takes that $X out of the team’s AWS budget.
Chargeback models in cloud computing
Each cloud chargeback model rests on cost allocation: assigning each cost to the team or app that used it. AWS describes three common starting models.
- An account-based model follows each AWS account, takes the least effort and needs no tags.
- A team-based model groups each team’s accounts with AWS Cost Categories.
- A tag-based model takes the most effort, and tags count only after you activate them for cost allocation.
On AWS, some costs can’t be tagged, such as some fees for Reserved Instances and Savings Plans. Microsoft says to plan your IT chargeback model with IT and finance, based on an agreed split of shared costs and commitment discounts.
Why it matters for your bill
- Cloud cost chargeback doesn’t change the provider’s invoice. But a team that pays its own share has a reason to reduce it.
- Coral rebalances CPU and memory requests on AKS and EKS to match real use, so the same pods fit on fewer nodes.
- Amoeba moves a virtual machine’s data disks onto one pool sized to your data, then rightsizes it autonomously.
- The free assessment works out your own figure.
