State Management and Fault Tolerance: - AWS Step Functions is a service that allows you to coordinate multiple AWS services into serverless workflows. It manages the state and execution of your tasks, ensuring that each step is completed in sequence. If a step fails, Step Functions can retry the failed step or handle errors based on the defined retry policies or error catchers. This means that only the failed steps will be reprocessed, rather than starting from the beginning. Decoupling and Scalability: - Using AWS Lambda functions in combination with Step Functions allows you to run each step of the process as a separate Lambda function. This provides scalability and makes it easier to handle compute-intensive tasks as they can be distributed across multiple Lambda invocations.

Operational Efficiency: - AWS Step Functions abstracts much of the complexity involved in managing the state and flow of tasks. This leads to a more operationally efficient solution, as you don't have to manually handle retries, error states, or intermediate results.
