Burstable instances have special characteristics that can affect both the provider costs and performance costs. We project your burstable costs, and your action items consider these bursting costs in recommending the optimal instance types for your workloads. For the first time, you can now see the breakdown of your provider and performance costs in terms of “base costs” and “burstable costs.”
Effective Provider Cost Breakdown for Burstable Instances
As an example, if an AWS burstable performance instance (T2, T3, T3a, and T4g) configured as unlimited depletes its CPU credit balance, it can spend surplus credits to burst beyond its baseline.
As shown below, the cost of these projected surplus credits can be seen in the breakdown of the burstable performance instance’s effective provider cost.
