3. 3 What’s openSUSE Leap Micro
4. A lightweight and modular Linux distribution developed by the openSUSE 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
5. openSUSE Leap Micro Features • Lightweight and Fast • Secure • Low-Maintenance • Built for Containerized and Virtualized workload
6. 6 Post VM strategy
7. • 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
8. openSUSE Leap Micro Features • Lightweight and Fast • Secure • Low-Maintenance • Built for Containerized and Virtualized workload => This session’s topic
9. 9 Why openSUSE Leap Micro is best choice for container and VM Host
10. 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
11. 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.
12. 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.
13. 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
14. 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 !!
