Key Features
Hyperconverged Infrastructure
Harvester’s HCI architecture allows for the convergence of compute, storage, and networking resources into a single, manageable entity. This approach eliminates the need for separate storage arrays, networking equipment, and compute resources, resulting in reduced complexity and improved resource utilization.
Virtualization and Containerization
Harvester supports both virtualization and containerization, enabling organizations to deploy a wide range of workloads, from traditional virtual machines to modern containerized applications. With Harvester, users can create and manage virtual machines, containers, and Kubernetes clusters from a single interface.
Snapshot and Restore Workflow
Harvester’s snapshot and restore feature enables users to create point-in-time snapshots of their virtual machines and containers, ensuring that data is always recoverable in the event of a failure or data loss. The restore workflow allows users to quickly recover from snapshots, minimizing downtime and data loss.
