Before comparison of Hashicorp Nomad vs Kubernetes, let’s have a brief overview of each Server Orchestration tool.

What is Kubernetes?

Kubernetes, also often abbreviated as K8s, is an open-source system designed to automate the deployment, scaling, and management of containerized applications. It essentially acts as a conductor for your containerized applications, ensuring they run smoothly and efficiently. Here’s a breakdown of its key aspects:


  • Deployment and Scaling: Kubernetes automates deploying containerized applications across a cluster of machines. This allows you to easily scale your applications up or down based on demand.
  • Management: It takes care of managing the lifecycle of your containers, including starting, stopping, restarting, and rolling updates.
  • Service Discovery: Kubernetes helps applications discover each other within the cluster, making it easier for them to communicate and work together.
  • Load Balancing: It automatically distributes traffic across multiple instances of your application, ensuring high availability and performance.
  • Health Monitoring: Kubernetes monitors the health of your containers and automatically restarts any that fail, keeping your application running smoothly.

  • Simplified Management: Kubernetes simplifies the management of complex containerized applications by automating many tasks.
  • Scalability: It allows you to easily scale your applications to meet changing demands.
  • Portability: Kubernetes applications can be deployed on any infrastructure that supports it, whether on-premises, in the cloud, or in a hybrid environment.

In essence, Kubernetes provides a platform for building and running highly scalable and resilient containerized applications.

What is Hashicorp Nomad?

Hashicorp Nomad, as previously mentioned, is a workload orchestrator, but it differs from Kubernetes in its focus and features:


  • While Kubernetes primarily targets container orchestration, Nomad is more versatile. It manages both containerized and non-containerized workloads, including:
    • Virtual machines (VMs)
    • Legacy applications
    • Batch jobs


  • Compared to Kubernetes, Nomad emphasizes simplicity and ease of use. It has a single binary executable and fewer dependencies, making it easier to set up and manage.


  • While both tools are highly scalable, Nomad excels in handling large deployments. It can handle over 10,000 nodes and has been benchmarked to manage millions of containers, potentially exceeding Kubernetes’ capabilities in specific scenarios.


  • Unlike Kubernetes’ built-in features for container orchestration (load balancing, configuration management, service discovery), Nomad has fewer built-in features. However, it integrates seamlessly with external tools like:
    • Consul for service discovery
    • Vault for secrets management

In essence, Nomad offers a simpler and more flexible approach to managing diverse workloads, particularly for large-scale deployments, while allowing integration with external tools for specific functionalities.

Choosing between Kubernetes and Nomad depends on your specific needs. If your focus is primarily on containerized applications and you need the full suite of built-in orchestration features, Kubernetes might be the better choice. However, if you have diverse workloads, require exceptional scalability, or prefer a simpler setup, Nomad could be a strong contender.

Hashicorp Nomad vs Kubernetes: A Detailed Comparison

Both Kubernetes and Nomad are popular tools for managing and orchestrating workloads, but they cater to different needs and offer distinct features. Here’s a comprehensive comparison to help you choose the right tool for your project:

Workload Support:

  • Kubernetes: Primarily focused on container orchestration, specifically for Linux containers.
  • Nomad: More versatile, supporting a wider range of workloads including:
    • Containerized applications (both Linux and Windows)
    • Virtual machines (VMs)
    • Legacy applications
    • Batch jobs


  • Kubernetes: More complex, with a full-featured platform and various components requiring configuration.
  • Nomad: Simpler and lightweight, with a single binary executable and fewer dependencies, making it easier to set up and manage.


  • Kubernetes: Well-suited for large deployments, capable of handling up to 5,000 nodes and 300,000 containers.
  • Nomad: Can potentially scale beyond 10,000 nodes and has been benchmarked to manage millions of containers, making it potentially more suitable for extremely large deployments.


  • Kubernetes: Offers end-to-end container orchestration features built-in, including:
    • Load balancing
    • Configuration management
    • Service discovery
    • Rolling updates
    • Health monitoring
  • Nomad: Lacks some built-in features compared to Kubernetes, but it integrates seamlessly with external tools for specific functionalities, such as:
    • Consul for service discovery
    • Vault for secrets management

Other Considerations:

  • Community and Ecosystem: Kubernetes has a larger and more active community with a vast array of tools and resources available. Nomad’s community is growing, but it may have fewer readily available resources.
  • Learning Curve: Due to its simplicity, Nomad might have a shorter learning curve compared to Kubernetes, which has a steeper learning curve due to its complexity and extensive feature set.

Here’s a table summarizing the key differences:

Workload SupportContainers (mainly Linux)Containers, VMs, legacy applications, batch jobs
ComplexityMore complexSimpler and lightweight
ScalabilityUp to 5,000 nodes and 300,000 containersOver 10,000 nodes and millions of containers (benchmarked)
Built-in FeaturesEnd-to-end container orchestration featuresFewer built-in features, integrates with external tools
Nomad vs K8s Comparison

Choosing between Nomad vs Kubernetes depends on your specific needs. Kubernetes is the established leader in container orchestration, but Nomad’s versatility and simplicity might be better suited for managing diverse workloads or large-scale deployments.
