Cast AI Analysis Surfaces Massive Kubernetes Infrastructure Waste
Cloud Native Now, Friday, March 7th, 2025
An analysis of Kubernetes clusters deployed in cloud computing environments by more than 2,100 organizations finds the average CPU utilization across Kubernetes clusters is just 10%, with memory utilization rates standing at only 23%, according to a report published today by CAST AI.
Overall, the report finds the over provisioning gap between requested resources and the infrastructure used is at 40% for CPUs and 57% for memory.
CAST AI president Laurent Gil said that given the uniform level of inefficiency being achieved by IT teams that have deployed Kubernetes on cloud services from Amazon Web Services (AWS), Microsoft and Google, the platform itself remains challenging to optimize.
As a result, the total cost of deploying cloud-native applications is much higher in many organizations than necessary, he added.
