Amazon EC2 Container Service vs Amazon EKS vs Docker Datacenter: What are the differences?

<Write Introduction here>

1. **Control Plane Management**: 
Amazon EC2 Container Service requires users to manage their own EC2 instances, whereas Amazon EKS automates the management of the Kubernetes control plane for better efficiency. On the other hand, Docker Datacenter provides a centralized management platform for containers which includes control plane management features similar to Kubernetes.

2. **Pricing Structure**:
Amazon EC2 Container Service is priced based on the underlying EC2 instances and other resources being utilized, while Amazon EKS has a separate pricing structure that includes a fee for the EKS service. Docker Datacenter also has its pricing model based on the number of nodes and support level chosen by users.

3. **Cluster Scalability**:
Amazon EC2 Container Service clusters have a limit on the number of instances that can be run per account, whereas Amazon EKS allows for scaling of clusters to a larger extent and automatically manages the infrastructure. Docker Datacenter's cluster scalability is flexible but may require manual intervention for larger scale operations.

4. **Compatibility with Kubernetes**:
Amazon EKS is specifically designed to be fully compatible with Kubernetes, allowing users to seamlessly run Kubernetes workloads without any modifications. In contrast, Amazon EC2 Container Service requires users to adapt their Kubernetes configurations to run on the platform. Docker Datacenter supports Kubernetes but may not offer the same level of compatibility as Amazon EKS.

5. **Security Features**:
Amazon EKS comes with built-in security features such as IAM authentication and encryption at rest for enhanced security of containerized workloads. Amazon EC2 Container Service requires users to set up their security measures separately. Docker Datacenter offers security features like access control and vulnerability scanning, but users may need to configure additional security layers.

6. **Ease of Deployment**:
Amazon EKS provides a more streamlined deployment process for Kubernetes clusters, as it automates many of the tasks involved in setting up and managing the infrastructure. Amazon EC2 Container Service and Docker Datacenter may require more manual configurations and setup steps, potentially increasing deployment time and complexity.

In Summary, Amazon EKS differentiates itself from Amazon EC2 Container Service and Docker Datacenter by offering automated control plane management, Kubernetes compatibility, enhanced security features, flexible cluster scalability, and streamlined deployment processes.
