   From Virtualization to Cloud Native
   •Cloud native computing uses an open source
   software stack to:
   – segment applications into microservices,
   – package each part into its own container
   – and dynamically orchestrate those containers
   to optimize resource utilization

    Key Takeaways
    Your Infrastructure MUST be:
    - Horizontally scalable
    - No single point of failure
    - Resilient and self-healing
    - Minimal operator overhead
    - Decoupled from the underlying platform
