What is Harvester?
Harvester is a modern, open-source hyperconverged infrastructure (HCI) solution designed to simplify the deployment and management of virtualization and containerized workloads. By combining compute, storage, and networking resources into a single, scalable platform, Harvester enables organizations to efficiently manage their infrastructure while reducing costs and improving operational efficiency.
Main Benefits of Harvester
Harvester offers several key benefits, including simplified infrastructure management, improved scalability, and enhanced security. By providing a single, integrated platform for managing virtualized and containerized workloads, Harvester helps organizations to streamline their operations and reduce the complexity associated with managing multiple, disparate systems.
Key Components of Harvester
Harvester is built on top of several key components, including Longhorn, a distributed block storage system, and Kubernetes, a container orchestration platform. By leveraging these components, Harvester provides a robust and scalable platform for deploying and managing virtualized and containerized workloads.

Harvester Snapshot and Restore Workflow
Creating Snapshots
Harvester provides a snapshot feature that allows you to create point-in-time copies of your virtual machines and containers. This feature is useful for creating backups and rolling back to a previous state in case of an issue.
Restoring Snapshots
To restore a snapshot, simply select the desired snapshot and click the restore button. Harvester will then restore the snapshot to the original state, including all data and configuration settings.
Harvester vs Alternatives
Comparison with Other HCI Solutions
Harvester is a relatively new player in the HCI market, but it has already gained significant traction due to its ease of use, scalability, and cost-effectiveness. When compared to other HCI solutions, such as VMware vSAN and Nutanix, Harvester offers several key advantages, including a lower cost of ownership and improved scalability.
Comparison with Container Orchestration Platforms
Harvester also competes with container orchestration platforms, such as Kubernetes and Docker Swarm. While these platforms offer robust container management capabilities, they often require additional infrastructure and management complexity. Harvester, on the other hand, provides a streamlined and integrated platform for deploying and managing both virtualized and containerized workloads.
