Kubernetes Cloud Repatriation Saves Millions for Data Platform Provider
Briefly

Yellowbrick, a SQL data platform provider, has realized significant cost savings of $3.9 million annually by migrating its workloads from public cloud services like AWS and Azure to its private Kubernetes-based infrastructure, built from reused hardware. Initially spending around $6 million annually on cloud services, Yellowbrick's EC3 deployment now operates with over 200 customer-returned servers, drastically reducing operational costs. The transition was challenging, requiring substantial upfront engineering effort, but ongoing administration is now manageable, and costs are dramatically lower compared to previous public cloud solutions.
We thought elasticity in the cloud had to be cheaper than building appliances, but we found out the hard way, it wasn't cheaper. It was much more expensive.
We utilize over 200 servers returned by customers, providing over 8,000 vCPUs and about 2 petabytes of object storage, vastly reducing our operational costs.
