Kubernetes vs Harvester – Finding the Ideal Infrastructure Solution

Nov 25th, 2025 | 6 min read

Kubernetes and Harvester are both powerful platforms, but they serve different purposes. Kubernetes is a leading container orchestration tool, designed to automate and scale containerized applications. Harvester, on the other hand, combines virtualization and container management in a hyper-converged platform. 

As companies seek more efficient solutions, understanding when to use each can optimize your infrastructure. In this comparison, we’ll break down what makes Kubernetes and Harvester unique, and how Simplyblock advances both for high-performance, scalable storage.

Kubernetes – Understanding Container Orchestration

Kubernetes is an open-source platform designed to automate the deployment, scaling, and management of containerized applications. It ensures high availability and reliability by managing complex containerized workloads across clusters. 

Kubernetes is the foundation for managing cloud-native applications, enabling efficient resource management and streamlined operations in dynamic environments. It’s a must-have for teams looking to scale applications in modern infrastructure.

Core Capabilities of Kubernetes

Kubernetes simplifies container management, ensuring your apps run efficiently at scale.

  • Automatically schedules containers for optimal performance
  • Restarts containers if they fail to maintain availability
  • Scales applications based on demand automatically
  • Distributes traffic efficiently across containers

How Kubernetes Works

Kubernetes organizes containers into Pods, making deployment and management across clusters easier.

  • Containers run in Pods, which are grouped into clusters
  • Automates the deployment and scaling of applications
  • Ensures persistent storage for containerized apps
  • Controls communication between containers for security

Why Kubernetes is Essential for Modern Infrastructure

Kubernetes is ideal for cloud-native applications, especially those with complex microservice architectures.

  • Manages complex microservice architectures efficiently
  • Supports deployments across hybrid and multi-cloud environments
  • Optimizes resource usage for cost-effective scaling
  • Streamlines CI/CD pipeline integration for faster releases

Harvester – Virtualization & Containerization

Harvester is an open-source hyper-converged infrastructure (HCI) platform designed to simplify the management of virtual machines and containerized workloads. It integrates compute, storage, and networking into a unified platform, making it ideal for organizations that need to manage both traditional VMs and containers in one solution. 

Harvester combines the power of virtualization with the flexibility of Kubernetes for seamless management of hybrid environments.

Core Capabilities of Harvester

Harvester offers robust capabilities to streamline the management of both VMs and containers.

  • Integrates compute, storage, and networking into a single platform
  • Simplifies the deployment of Kubernetes clusters on virtualized infrastructure
  • Supports the creation and management of virtual machines alongside containers
  • Enables scalability for both virtualized and containerized workloads

How Harvester Works

Harvester uses a combination of KVM (for VMs) and Kubernetes (for containers) to create a unified, efficient infrastructure.

  • Uses KVM for virtualization to manage VMs
  • Deploys Kubernetes clusters with integrated storage solutions
  • Combines virtualized and containerized workloads into one environment
  • Manages networking, storage, and compute resources in a unified way

Why Harvester is a Game-Changer for Hybrid Environments

Harvester is ideal for organizations looking for an all-in-one platform to manage both VMs and containers in hybrid environments.

  • Supports both virtualization and containerization in a single platform
  • Simplifies the management of hybrid cloud and multi-cloud environments
  • Reduces infrastructure complexity by integrating multiple layers
  • Provides a cost-effective solution for managing traditional and cloud-native applications

Kubernetes vs Harvester – Comparing Their Roles in Infrastructure

Kubernetes and Harvester serve different purposes but can work together in modern IT environments. Below are the key differences:

Running Postgres on Kubernetes vs Harvester

Running Postgres on Kubernetes offers scalability and flexibility within containerized environments, while Harvester provides a unified approach to managing both virtual machines and containers, making it ideal for hybrid cloud setups.

If Postgres is the main workload you care about, it’s often easier to treat it as a platform rather than something you hand-roll on top of your virtualization choice. Vela is a Postgres platform by Simplyblock that runs on Kubernetes, providing high-performance PostgreSQL with built-in automation, backups, and scaling.
