AWS Step Functions acts as a high-level layer, allowing us to seamlessly integrate with microservices.
AWS Step Functions is adaptable to various needs and integrates well with all AWS services. It is scalable, supports rate limiting, and simplifies microservices integration, though it has a challenging setup and declaratory language. Improvements are needed in data size limits, pricing, support, and clarity of the licensing model, which can increase costs as usage grows, creating a dependency on the Amazon ecosystem.
