What is loosely coupled and tightly coupled in AWS?

Unlike tightly coupled architecture which runs thousands of parallel processes or cores that are dependent on one another to perform a calculation, loosely coupled architecture runs smaller jobs in large numbers on a single node with parallelization occurring within the node.

Which AWS service supports loose coupling?

Loosely coupled simulations can be deployed with end-to-end services and solutions such as AWS Batch and AWS ParallelCluster, or through a combination of AWS services, such as Amazon Simple Queue Service (Amazon SQS), Auto Scaling, AWS Lambda, and AWS Step Functions.

What is a benefit of the AWS design concept loose coupling?

The goal of a loose coupling architecture is to reduce the risk that a change made within one element will create unanticipated changes within other elements. Limiting interconnections can help isolate problems when things go wrong and simplify testing, maintenance and troubleshooting procedures.
