When is Amazon EC2 a good fit?

Amazon EC2 provides resizable virtual servers when an application needs control over its operating system, instance configuration, or long-running server environment.

AWS Lambda runs code in response to events without requiring you to manage servers, making it suitable for short-lived tasks such as processing an uploaded file.

Amazon ECS orchestrates containers using AWS’s container orchestration service; Amazon EKS is a managed Kubernetes service for workloads that use Kubernetes.

What does AWS Fargate manage for ECS or EKS containers?

AWS Fargate provides serverless compute for containers used with ECS or EKS, so you do not manage the underlying servers.
