Orchestrating backend services with AWS Step Functions

The problem

In many use cases, there are processes that need to execute multiple tasks. We build micro-services or server-less functions like AWS Lambda functions to carry out these tasks. Almost all these services are stateless functions and there is need of queues or databases to maintain the state of individual tasks and the process as a whole. Writing code that orchestrates these tasks can be both painful and hard to debug and maintain. It’s not easy to maintain the state of a process in an ecosystem of micro-services and server-less functions.
