Building cost-effective AWS Step Functions workflows


Builders create AWS Step Functions workflows to orchestrate multiple services into business-critical applications with minimal code. Customers are looking for best practices and guidelines to build cost-effective workflows with Step Functions. This blog post explains the difference between Standard and Express Workflows. It shows the cost of running the same workload as Express or Standard Workflows.
