Case Study: Sharethrough achieves 62% AWS cost savings and improved reserved-instance utilization with Spot (Elastigroup)

Sharethrough Improves RI utilization and drastically reduces AWS costs with Elastigroup

Sharethrough, a large native advertising company serving 30 billion impressions a month, was running on Amazon EC2 and Auto Scaling Groups and struggling with high AWS costs and underutilized Reserved Instances. After discovering Spot at the AWS Summit, Sharethrough engaged Spot’s Elastigroup to evaluate using Spot Instances alongside their existing on-demand and reserved capacity to improve RI utilization and lower cloud spend.

Spot implemented Elastigroup to import Sharethrough’s ELB configuration, run mixed instance types (Spot, On-Demand, Reserved), prioritize reservation usage, and provide intelligent auto-scaling and predictive instance draining. The result: Sharethrough drastically improved reserved-instance utilization, moved much of its workload to Spot, and cut cloud computing costs by 62%, with Spot’s Elastigroup becoming the primary model for their infrastructure.
