Solving concurrency challenges with AWS Step Functions

Asynchronous architectures are everywhere in modern cloud development, but they bring unique concurrency challenges that can trip up even experienced engineers. When your Step Functions are running wild and your downstream services are getting overwhelmed, you need practical solutions that actually work in production. In this episode we will cover: Why traditional SQS concurrency controls fall short with asynchronous Step Functions How to implement semaphore-based concurrency control using native AWS service integrations Managing workflow-level concurrency limits for protecting third-party dependencies Entity-level concurrency control to prevent simultaneous operations on the same resource Combining multiple semaphore strategies for complex real-world scenarios Known limitations and scaling considerations when using DynamoDB for concurrency control A practical coupon redemption example that demonstrates these patterns in action For more details check ⁠here⁠.
