This is an extended version of the talk I gave at Serverless Days TLV

Serverless is a a very convenient way to quickly write and deploy code, but not having a server with shared memory and/or disk storage makes stateful flows hard to implement and analyze.
This session will provide an overview on the different approaches for achieving this (queues, orchestration services, etc.) and go in depth into one of them - AWS’s Step Functions.
We will see how state, scaling, error handling and parallelization can be achieved via configuration and also discuss drawbacks and which use cases are a good fit for Step Functions.
