Less Waste, Less Work - Using VM Lifetime for Resource Cleanup

Learn how to implement automated virtual machine lifecycle management in OpenStack environments through this 39-minute conference talk from the OpenInfra Foundation. Discover how large-scale private clouds like Verda (LINE Corp.) and YNW (Yahoo Japan Corp.) addressed the persistent problem of forgotten or unused VMs that drain compute and storage resources. Explore the development and deployment of the "lifetime" feature, an automated expiry mechanism that was successfully implemented in Flava cloud following the merger of LINE and Yahoo Japan Corp. Examine real-world data quantifying the impact of idle VMs on resource utilization and understand the design considerations for managing tens of thousands of virtual machines. Dive into the technical implementation details, including handling of exceptions and special cases, while reviewing actual deployment results. Gain practical insights and a clear blueprint for automating VM lifecycle management in your own OpenStack environments to improve operational efficiency and optimize resource utilization.
