Scaling Simplified: How Nomad Bridges the Kubernetes Skills Gap 

Session detail: Kubernetes is a trendy solution, but in most cases, there is a skills gap when deploying and maintaining Kubernetes. I am looking at Nomad to bridge the gap and provide a simpler solution to run self-hosted platform infrastructure such as runners for CI/CD pipelines, Packer workflows to build image, send build metadata to HCP Packer, and lastly running HCP Terraform Agents. 

Hashi Areas / technologies covered: Terraform, Nomad, HashiCorp Cloud Platform, Packer, Infrastructure Lifecycle Management 

Scaling Simplified: How Nomad Bridges the Kubernetes Skills Gap 

When it comes to orchestration, Kubernetes is often the go-to choice. Its popularity is undeniable, but many engineering teams quickly find themselves grappling with its complexity. Kubernetes’ steep learning curve and operational challenges have left many asking a crucial question: is there an easier way to scale infrastructure without compromising capability? The answer may lie in Nomad, a lightweight yet powerful alternative that’s steadily gaining traction for its simplicity and efficiency. 

If you’ve ever found yourself struggling with the intricacies of Kubernetes or simply looking for a more straightforward solution to scale your infrastructure, then this upcoming session at HashiConf 2024 hosted by River Point Technology’s very own Ben Lykins, is for you. Titled “A Beginner’s Journey: Scaling Self-Hosted Platform Infrastructure with Nomad”, Ben’s session aims to provide the audience with actionable insights on how you can leverage Nomad to overcome the challenges often associated with Kubernetes. 

Why Nomad? Understanding the Challenges with Kubernetes 

Kubernetes is widely praised for its ability to manage containerized applications at scale, but the truth is, it often requires a significant amount of expertise to run efficiently. The inherent complexity can lead to several challenges, including: 

  • Steep Learning Curve: Kubernetes has a vast ecosystem that includes various moving parts such as Pods, Deployments, Services, Ingress, and more. For newcomers, this can be overwhelming and time-consuming to learn. 
  • Resource Intensity: Running Kubernetes clusters can be resource-heavy, particularly in smaller or self-hosted environments where cost and simplicity are critical. 
  • Operational Complexity: Maintaining and updating Kubernetes clusters involves careful planning and a deep understanding of how the different components interact with each other. 

While Kubernetes is an excellent solution for many organizations, its complexity can lead to operational bottlenecks. This is where Nomad shines as an alternative—providing a simpler, more flexible platform for managing workloads. 

What is Nomad? 

HashiCorp Nomad is a flexible workload orchestrator that’s designed to run containers, VMs, and other application types on any infrastructure. Unlike Kubernetes, Nomad is lightweight and easy to adopt, yet powerful enough to handle production-grade workloads. 

Here are a few key reasons why Nomad stands out as a strong contender for self-hosted platform infrastructure: 

  • Simplicity: Nomad’s core is lightweight, making it easier to install and manage than Kubernetes. 
  • Flexibility: While Kubernetes is designed specifically for containers, Nomad can orchestrate a variety of workloads, including containers, VMs, and batch jobs. 
  • Scalability: Nomad scales horizontally and can handle thousands of nodes without compromising performance. 
  • Integration with HashiCorp Tools: Nomad works seamlessly with other HashiCorp products such as Terraform, Consul, and Vault, creating an ecosystem that’s perfect for managing infrastructure as code (IaC). 

How Nomad Bridges the Skills Gap 

In this session, we’ll explore how Nomad addresses many of the pain points experienced by those who struggle with Kubernetes. Whether you’re new to infrastructure management or simply looking for a more efficient way to run self-hosted platforms, Nomad provides a simpler, more approachable solution. Here’s how: 

1. Simple Configuration Language 

Nomad’s use of HCL (HashiCorp Configuration Language) makes it incredibly simple to define and manage infrastructure. HCL’s human-readable syntax allows users to quickly and clearly define job specifications, configurations, and policies.  

With Nomad, HCL streamlines workflows by offering a declarative approach, making it easy for both beginners and seasoned engineers to understand and use. This simplicity reduces the learning curve and enhances productivity, especially when working with HashiCorp’s broader ecosystem like Terraform and Vault. 

2. Single Binary 

Nomad’s architecture as a single binary makes it remarkably simple to deploy and manage. With no external dependencies or complex setup, Nomad can be easily installed and run on any environment, from local development to large-scale production. This single binary handles all core functions—scheduling, orchestration, and resource management—without needing multiple components or services.  

Its simplicity reduces operational overhead, speeds up installation, and enables quick portability between on-premises and cloud environments, making Nomad an efficient and user-friendly solution for managing workloads at any scale. 

3. Fit in HashiCorp’s Ecosystem 

Nomad’s seamless integrations with other HashiCorp products, like Vault, Consul, and Terraform, make it a powerful part of a unified infrastructure ecosystem. With these integrations, Nomad enhances security, networking, and provisioning workflows. Vault provides dynamic secrets management, ensuring sensitive data remains secure, while Consul offers service discovery and networking automation. Terraform simplifies infrastructure provisioning, allowing teams to define and deploy infrastructure as well as Nomad con. These integrations streamline operations, increase efficiency, and create a cohesive, end-to-end solution for managing complex infrastructure environments. 

Nomad vs. Kubernetes: Is It Time to Make the Switch? 

While Kubernetes has long been the gold standard for container orchestration, it’s not without its downsides—especially for teams looking for a more straightforward way to manage their platform infrastructure. Nomad’s lightweight architecture and simplicity make it an excellent alternative for those who want to minimize complexity while still scaling effectively. 

In this session, you’ll learn whether Nomad is the right fit for your organization and how you can start using it to build scalable, self-hosted platforms. 

Conclusion: Bridging the Gap with Nomad 

Kubernetes will likely remain a dominant force in the infrastructure space, but for those looking for an alternative that offers ease of use without sacrificing scalability, Nomad is a strong contender. With its ability to run various workloads, integrate with HashiCorp’s suite of tools, and scale efficiently, Nomad provides a simpler solution to managing self-hosted platform infrastructure.
