What is Kubernetes and how much does it cost?

Small to Medium Cluster (Development or Small Production Scale)

  • Nodes: 3-5 nodes, each with 2 vCPUs and 4 GB RAM.
  • Networking, Storage, and Additional Services: Basic setup with moderate network traffic, storage, and database usage.

Estimated Monthly Cost: $300 to $1000

Medium to Large Cluster (Medium Production Scale)

  • Nodes: 5-15 nodes, each with 4 vCPUs and 16 GB RAM.
  • Networking, Storage, and Additional Services: More extensive use of networking, higher storage requirements, possibly including managed databases, load balancers, and enhanced security features.

Estimated Monthly Cost: $1500 to $5000

Enterprise Level (Large Production Scale)

  • Nodes: 20+ nodes, each with 8 or more vCPUs and 32 GB RAM or higher.
  • Networking, Storage, and Additional Services: High network throughput, high storage and database requirements, advanced security, auto-scaling, multi-region deployment, and additional managed services.

Estimated Monthly Cost: $10,000 to $50,000+

Additional Considerations:

  • Cloud Provider Pricing Models: Different providers have different pricing models. AWS, Azure, and GCP are popular choices, each with unique pricing.
  • Managed Kubernetes Services: Services like Google Kubernetes Engine (GKE), Amazon EKS, or Azure AKS can reduce management overhead but may have additional costs.
  • Support and Maintenance: Depending on your team's expertise, you might need support plans or external consultants, which can add to the cost.
  • Scaling Costs: If your traffic is variable, you might benefit from auto-scaling features, but this will impact costs.
  • Storage and Networking: Higher or more sophisticated storage (like SSDs or distributed file systems) and networking demands will increase costs.

These estimates are very rough; actual costs depend on specific requirements, cloud provider pricing changes, and other variables. It's advisable to use cloud provider pricing calculators (like AWS Pricing Calculator, Azure Pricing Calculator, or Google Cloud Pricing Calculator) for a more accurate estimate based on your exact needs.
