Compare Hashicorp Nomad Certification Vs Kubernetes Certification
- Flexible Workload Support – Kubernetes has been created to orchestrate containers hosting workloads, whereas Nomad is recognized more for a workload scheduler that can be used to manage the deployment of both legacy and containerized applications, and scheduling batch jobs.
- End-to-end Container Orchestration – Kubernetes offers end-to-end container orchestration services comprising load balancing, configuration management, routing, feature gates, and service discovery. Nomad is fundamentally a task scheduling platform that can orchestrate different workload types as an expanded feature.
- Scalability – Both platforms has been created for autoscaling in large deployments, however Nomad is considered favorably to scale larger clusters than Kubernetes, Whereas Kubernetes has been built to support clusters with up to 5,000 nodes orchestrating a maximum of 300,000 containers, Nomad could scale clusters exceeding 10,000 nodes in production and surpassed the benchmark for the two million container challenge.
- Deployment Consistency – Kubernetes provides different deployment and management environments to make it easy for organizations to perform development and testing before pushing apps to deployment. These may create instability in configuration and abilities when going live. Nomad utilizes a single, portable library that could be deployed on any environment to offer the same user experience across different platforms.
