Case Study: PubNative achieves 80% AWS cost reduction and improved performance and availability with Spot (Spotinst Elastigroup)

PubNative Decreases Cost By 80% Using Spotinst Elastigroups For Their Mesos, Spark, ElasticSearch And Presto Clusters

PubNative, a global mobile monetization platform, faced rapidly rising AWS infrastructure costs and operational overhead supporting a diverse Apache Mesos environment (Chronos, Elasticsearch, Kibana, Logstash, Spark, Presto) across multiple regions and accounts. They struggled to efficiently use Spot Instances and integrate spot management with their OpsWorks/Beanstalk-based deployment pipeline, which left them wasting compute capacity and hampered real‑time analytics performance until they engaged Spot with Spotinst Elastigroups.

Spot implemented its Spotinst Elastigroups platform to automate diversified Spot bidding, dynamically select optimal instance types, and integrate with Mesos/Marathon so containers and workloads (including Sidekiq workers) move to the right capacity automatically; the Spot console also improved Reserved Instance utilization visibility. The result was dramatically lower costs (an 80% reduction headline figure, with finance teams reporting consistent ~70% savings versus on‑demand), improved performance and availability, and far less management overhead thanks to Spot.
