AWS Lambda vs ECS: Which is Better for My Project?

What are the main differences between AWS Lambda and ECS?

AWS Lambda is a serverless compute service that runs code in response to events, while ECS (Elastic Container Service) is a container orchestration service that allows you to run and manage Docker containers.

When should I use AWS Lambda instead of ECS?

Use AWS Lambda for event-driven applications with short execution times and when you want to avoid managing servers. ECS is better for long-running applications and when you need more control over the environment.

Can I use both AWS Lambda and ECS in the same project?

Yes, you can use both services together. For example, you might use Lambda for processing events and ECS for running microservices.

What are the cost implications of using AWS Lambda vs ECS?

AWS Lambda charges based on the number of requests and execution time, while ECS costs depend on the underlying EC2 instances or Fargate usage. Lambda can be cheaper for low-traffic applications.
