Keeping Real-Time Auctions Running During Rollout - From White-Knuckle to Continuous Deployments

Explore a case study on improving the reliability of an Elixir service for real-time auctions during deployments in this Lambda Days 2023 conference talk. Learn how Whatnot overcame challenges associated with deploying an Elixir cluster that maintains stateful connections and manages distributed state. Discover the journey from risky, off-peak hour deployments to confident continuous deployments at any time. Gain insights into the implementation of automated testing strategies that simulate various conditions, including random node failures, to verify system integrity. Understand how incorporating these tests into the CI pipeline significantly enhanced deployment reliability, minimizing data inconsistencies and disruptions to ongoing auctions. Benefit from practical knowledge on improving buyer satisfaction and preventing financial losses for sellers in real-time auction systems.
