AWS Lambda Finite State Machine Workflows

A framework for running Finite State Machine (FSM) Workflows on

1. AWS Lambda for code execution,
2. (Optionally) AWS ECS for long-running code execution,
3. AWS Kinesis for event dispatch
4. (Optionally) AWS DynamoDB for event dispatch
5. (Optionally) AWS SNS for event dispatch
6. (Optionally) AWS SQS for event dispatch
7. Support for primary and secondary event dispatch mechanisms
8. (Optionally) AWS DynamoDB for checkpointing
9. (Optionally) AWS DynamoDB for retries with backoff
10. (Optionally) AWS SQS for retries with backoff
11. (Optionally) Memcache for idempotency
12. (Optionally) AWS DynamoDB for idempotency
13. (Optionally) AWS CloudWatch for error and failure monitoring

The FSM implementation is inspired by the paper:
