Case Study: Chegg achieves 70% EC2 cost savings and simplified ECS infrastructure management with Spot

Chegg Cuts EC2 Costs by 70% While Simplifying ECS Infrastructure Management

Chegg, the student-first connected learning platform, migrated to microservices on AWS ECS and saw its EC2 footprint jump from roughly 600 to 1,200 instances, creating rising Opex and an oversubscribed operations team. To contain costs and simplify ECS infrastructure management, Chegg engaged Spot and adopted Spot Elastigroup to automate instance provisioning and management.

Spot Elastigroup automated Spot Instance provisioning for Chegg’s ECS workloads, abstracted away Spot and RI management, and provided clear cost-allocation dashboards and one-click cluster operations. As a result, Spot helped Chegg reduce EC2 costs by over 70%, recover value from unused Reserved Instances, automate EC2 maintenance events without disruption, free operations to focus on higher-value work, and deliver rapid time-to-value with 24/7 support.
