Harvester deep dive

This stream provides a deep dive into Harvester v0.2, an open-source hyper-converged infrastructure (HCI) solution designed for the cloud-native ecosystem, emphasizing its architecture, new features like live migration, and integration with Rancher 5:42.
Key Takeaways:
• Harvester serves as an open-source alternative to proprietary HCI tools like vSphere, utilizing Kubernetes APIs to manage both VMs (via KubeVirt) and containers across edge, cloud, and data centers 14:57.
• The architecture ensures high availability by promoting the first three nodes as management nodes; if one fails, a worker node is automatically promoted to maintain the cluster 20:26.
• Despite multiple layers, performance remains near-native because KubeVirt runs directly on the bare metal host, with Kubernetes solely handling orchestration logic 29:15.
• Version 0.2 introduces key features such as fast block device support using Longhorn backing images, live VM migration, backup and restore capabilities to S3 or NFS, and iPXE network installation 35:12.
• A Harvester node driver allows users to provision Kubernetes clusters directly from the Rancher UI, treating Harvester as the underlying infrastructure provider 37:41.
The session concludes with a live demonstration of the installation process and live migration, showcasing the ease of managing VMs in a cloud-native environment 49:00.
