    community Specialized for containerization and virtualization, enabling rapid deployment and flexible operations Inherits the stability and security of SUSE Linux Enterprise 4 openSUSE Leap Micro Overview
  2. openSUSE Leap Micro Features • Lightweight and Fast • Secure

    • Low-Maintenance • Built for Containerized and Virtualized workload
  3. • Nutanix AHV • Cloud (Paid user) • Proxmox •

    Harvester • KVM • Move to Cloud Native(Container, K8s) *These are representative examples. 7 VMware Issues from an Open Source Community The Post-VMware issue has created significant market disruption
  4. openSUSE Leap Micro Features • Lightweight and Fast • Secure

    • Low-Maintenance • Built for Containerized and Virtualized workload => This session’s topic
  5. Regular Linux VS openSUSE Leap Micro • Thousands of packages

    • All co-installable • Same lifecycle Containerized and VM workload • Independent lifecycle openSUSE Leap Micro • Small footprint • Immutable OS • Secure and Compliance Regular Linux openSUSE Leap Micro
  6. What Small footprint is benefit VM Container Regular Linux OpenSUSE

    Leap Micro • A attack surface is small. • It can use memory and CPU efficiently. • Disk Space Savings • These component are extra attack surface. • There are overhead.
  7. Why Immutable OS is beneficial for Container/VM Host • Speed

    Deployment and Efficiency Management: ◦ Rapid deployment of new environments. ◦ Easy rollback to previous states. • Reliability and Stability: ◦ Consistent configuration across environments. ◦ Reduced human error. ◦ Enhanced security through frequent updates. • Security: ◦ Reduced attack surface. ◦ Simplified auditing. ◦ Compliance with regulations. • Scalability: ◦ Easy replication of identical environments.
  8. My home lab environment Good point: • Cost Saving! •

    Unified Maintenance way (K8s lifecycle, IaC) • Easy to Deploy openSUSE Leap Micro 6.0 K3s KubeVirt Tumbleweed Fedora
  9. Conclusion openSUSE Leap Micro is : • Best for container

    and VM host. ◦ Secure ◦ Lightweight and Fast ◦ Immutable OS ◦ Stable and Reliable Let’s play openSUSE Leap Micro !!
