Amazon Simple Queue Service enables the separation of the content processing workload from the user-facing platform by using a message queue. The user platform can submit video transcoding tasks to the queue, which the content processing component can consume and process independently, scaling according to the queue length. Amazon S3, being an object storage service, does not provide the messaging system for a decoupled architecture. Amazon Virtual Private Cloud is a networking service for isolated cloud resources and does not directly support application decoupling. AWS Lambda can process events but is itself neither a decoupling mechanism nor a queuing service, and it requires interaction with services like SQS to enable processing independent of the workload generation source.
