Which solution meets these requirements?

Explanations:

While launching containers on EC2 with EC2 instance worker nodes is possible, it does not provide a managed orchestration solution, making it harder to maintain cloud agnosticism and uniformity in configurations and tools.

Amazon EKS is a managed Kubernetes service that supports open-source software and allows for cloud-agnostic configurations. It provides a consistent environment for deploying containers across different cloud platforms, fulfilling the requirement for the same configuration and tools across production systems.

Amazon ECS is a managed container orchestration service that is not based on Kubernetes, which may not meet the company’s requirement for cloud-agnostic solutions. Additionally, using AWS Fargate abstracts infrastructure management, which might not align with the desire for consistent configuration across production systems.

Similar to option C, Amazon ECS with EC2 instance worker nodes does not utilize Kubernetes, limiting its flexibility and cloud-agnostic capabilities. This solution does not support the need for the same configuration and administration tools across production systems as effectively as EKS would.
