This 15-minute conference talk by Harsh Jain at DevConf.IN 2025 explores an innovative architectural design for creating fully isolated virtual machines on bare-metal servers with just milliseconds of latency. Learn how to achieve 99.99% availability for product offerings through optimal usage of open-source tools like Nomad, Firecracker, and Ignite. Discover how engineering teams can independently create VMs on bare metal with minimal code, reducing reliance on cloud provider managed services. The presentation covers strategies for minimizing cloud costs while maintaining high availability, addressing security challenges, and delivering tangible business value. This architecture has enabled the creation of over 2 million ephemeral VMs within months of implementation.
