ARC312: Why Regional Reserved Instances Are a Game Changer for Netflix - a podcast by AWS

Learn how Netflix efficiently manages costs associated with 150K instances spread across multiple regions and heterogenous workloads. By leveraging internal Netflix tools, the Netflix capacity team is able to provide  deep insights into how optimize our end users' workload placements based on financial and business requirements. In this session, we discuss the efficiency strategies and practices we picked up operating at scale using AWS since 2011, along with best practices used at Netflix. Because many of our strategies revolve around Reserved Instances, we focus on the evolution of our Reserved Instance strategy and the recent changes after the launch of regional reservations. Regional Reserved Instances provide tremendous financial flexibility by being agnostic to instance size and Availability Zone. However, it's anything but simple to adopt regional Reserved Instances in an environment with over 1,000 services, that have varying degrees of criticality combined with a global failover strategy.
