Case Study: Magnetic achieves 90% EC2 Spot usage and $1M+ annual savings with Spot

Magnetic Significantly Increase Spot Instance Usage Through Spotinst

Magnetic, an AI-driven advertising company, needed to move 90% of its workloads to EC2 Spot but found complex systems like Hadoop and time-consuming processes were blocking progress. To accelerate the migration and enable stateful workloads on Spot Instances, Magnetic engaged Spot and adopted Spot’s Elastigroup solution.

Spot implemented Elastigroup to mix On‑Demand, Reserved and stateful Spot instances, simplify migrations (reducing some environments from 6+ months to hours), and support stateful features like private IP retention and volume reattachment. As a result, Magnetic reached its 90% Spot target in months instead of a year, realized over $1 million in savings in the past 12 months with an expected additional ~$1 million annually, and benefited from rapid feature delivery and stronger confidence in Spot’s support.
