EKS Standard:
- Control Plane:
- AWS manages the Kubernetes control plane.1
- Worker Nodes:
- You manage the worker nodes (EC2 instances).2 This gives you maximum control over the underlying infrastructure.
- You can use EKS Managed Node Groups for some automation, or manage them entirely yourself.3
- Use Cases:
- Ideal for applications requiring fine-grained control over EC2 instances.4
- Suitable for stateful applications and workloads with specific hardware requirements.5
EKS Fargate:
- Control Plane:
- AWS manages the Kubernetes control plane.
- Worker Nodes:
- AWS manages the underlying infrastructure.6 You deploy pods, and Fargate provisions the necessary compute resources.7
- Serverless operation: you don’t manage EC2 instances.8
- Use Cases:
- Best for stateless, event-driven, and serverless applications.9
- Simplifies operations by eliminating the need to manage worker nodes.10
EKS Anywhere:
- Control Plane & Worker Nodes:
- You manage the Kubernetes cluster on your own on-premises infrastructure.11
- Extends EKS to your data centers, providing a consistent Kubernetes experience.12
- Use Cases:
- For organizations with on-premises infrastructure or hybrid cloud requirements.13
- Enables consistent Kubernetes deployments across different environments.14
EKS Auto Mode:
- Control Plane:
- This mode is designed to further automate the management of the EKS control plane.15 It aims to reduce the operational burden of managing the control plane.16
- Worker Nodes:
- Worker nodes are still managed either by the user, or by managed node groups.
- Use Cases:
- Designed to simplify EKS operations.17
- Useful for those who want to reduce the amount of interaction they have with the control plane of their EKS clusters.
- It is designed to make EKS more hands off.18
Key Differences Summarized:
- Infrastructure Management: The primary difference lies in who manages the worker nodes. EKS Standard gives you full control, Fargate eliminates node management, and EKS Anywhere lets you manage clusters on-premises.19 EKS Auto mode, focuses on automating the control plane.
- Serverless vs. Managed: Fargate is a serverless option, while EKS Standard and EKS Anywhere involve managing infrastructure.20
- On-Premises vs. Cloud: EKS Anywhere extends EKS to on-premises environments.21
Here’s the corrected and updated comparison of EKS Standard, EKS Fargate, EKS Anywhere, and EKS Auto Mode as of March 2025:
Major Differences Between EKS Standard, EKS Fargate, EKS Anywhere, and EKS Auto Mode
| Feature | EKS Standard | EKS Fargate | EKS Anywhere | EKS Auto Mode |
|---|---|---|---|---|
| Deployment Model | Managed control plane with EC2-based worker nodes | Serverless Kubernetes pods running on Fargate | Self-managed Kubernetes clusters on on-premises infrastructure | Fully managed Kubernetes cluster with simplified infrastructure setup |
| Node Management | Users provision and manage EC2 instances as worker nodes | No node management, Fargate provisions compute resources automatically | Users manage physical/virtual nodes on their own infrastructure | AWS manages the cluster, but users must provide an existing VPC |
| Control Plane | AWS-managed control plane | AWS-managed control plane | Self-managed control plane | Fully managed by AWS |
| Worker Nodes | EC2 instances (managed by users) | No worker nodes, only Fargate pods | Self-managed nodes (bare metal, VMs, cloud) | Managed by AWS, automatically optimized |
| Use Case | Workloads requiring full control over EC2-based compute and networking | Serverless Kubernetes for lightweight and auto-scaling workloads | Hybrid cloud, on-premises Kubernetes deployments | Users who want to run Kubernetes without managing infrastructure |
| Cost Model | Pay for EC2 instances + control plane separately | Pay per pod running on Fargate (no EC2 costs) | Costs depend on on-prem infrastructure; AWS charges EKS Anywhere licensing fees | Pay only for running workloads, infrastructure cost is included |
| Scaling | User-defined scaling using EC2 ASG | Autoscaling based on Fargate pods | Scaling depends on on-premises capacity and user configurations | Fully automated scaling, AWS optimizes resources dynamically |
| Networking | Requires VPC setup and security group configuration | Uses AWS VPC with automatic networking | User-managed networking based on on-premises setup | Requires an existing VPC (AWS does not create it) |
| Security & IAM | Users configure IAM roles, security groups, and network policies manually | AWS manages IAM roles per pod and provides pod-level isolation | Self-managed security, integrates with on-prem security controls | AWS manages IAM roles and security at the Kubernetes level but does not configure VPC security |
| Storage | Supports EBS, EFS, FSx, and custom storage | Integrates with AWS storage but has some limitations on persistent volumes | User-managed storage solutions | AWS auto-configures storage, but users must define storage classes |
| Maintenance & Updates | Users responsible for cluster upgrades and node patching | AWS maintains infrastructure updates, users handle Kubernetes updates | Self-managed; updates and patches controlled by users | Fully managed, AWS handles all updates and patches |
| Integration | Works with EC2, ALB, ASG, IAM, and other AWS services | Deep integration with AWS services but limited workload flexibility | Works with on-prem infrastructure and edge computing | Fully integrated with AWS services, but less customizable |
| Customizability | High—users choose instance types, storage, networking, etc. | Low—AWS handles everything | High—tailored for on-premises needs | Limited—AWS optimizes everything for ease of use |
| Operational Overhead | Medium—users manage EC2 nodes, networking, and updates | Low—no node management, AWS handles infra | High—users handle everything (network, nodes, security) | Very Low—AWS fully manages Kubernetes and scaling |
Key Takeaways (March 2025 Updates)
- EKS Standard → Best for users needing full control over compute, networking, and security.
- EKS Fargate → Best for serverless Kubernetes, where users don’t want to manage EC2 instances.
- EKS Anywhere → Best for hybrid and on-prem Kubernetes, allowing full infrastructure control.
- EKS Auto Mode → Best for users wanting fully managed Kubernetes, but requires an existing VPC.
