Stateful Functions Demystified: Manage Complex States in Serverless JavaScript

Your serverless functions are running, and are memory efficient, now you want to some state. But serverless generally doesn't have state. You know what to do, but how ? Where does JavaScript make it difficult to manage state and how to solve them?

This talk goes over all the questions above along with complex state management for serverless functions written in JavaScript. It starts with what are the use cases that actually needs state, how to deal with it, the commons patterns of state management you use in JavaScript and why they fail in serverless. But state management isn?t just about storage; it?s about consistency, reliability, and scalability all of these will be touched upon how they can be measured, and how to advance such strategies.

Some of the problems and solutions I will be tackling:

- What are the different ways to achieve state

- Performing distributed transactions and compensating state actions

- How to externalize state in serverless environments without sacrificing performance.

- Implementation of asynchronous operations on your state

- The JavaScript way of maintaining cache for state management

- Case studies and real-world examples of complex state management scenarios

- A roadmap for designing scalable, resilient stateful applications in the serverless era.

All of these will be explained with examples, keeping in mind the quirks of JavaScript and how they play well with these cloud based solutions. As the talk closes you will be leaving with advanced knowledge and application strategies for your applications as stateful applications become the future of serverless architectures.
