Case Study: HackerRank cuts EC2 costs and streamlines releases with PerfectScale by DoiT

HackerRank cuts EC2 costs by 50% with PerfectScale

HackerRank, a platform for evaluating developer skills, faced challenges with its AWS infrastructure as its user base grew. Pipeline inefficiencies were causing frustrating downtime and lengthening release cycles, while costs were rising. They partnered with DoiT and leveraged its PerfectScale for Spot technology to address these issues.

DoiT implemented a multi-step solution that included modernizing the build pipeline and using PerfectScale for Spot to optimize Auto Scaling groups. This approach enabled the confident adoption of Spot Instances. The results were a 24% decrease in overall EC2 expenses, a 50% reduction in on-demand EC2 spend for non-production environments, and a streamlined release cycle that improved service reliability for customers.
