Our speakers for this evening:

⭐️Yan Cui (@theburningmonk) - "Lessons from running AppSync in production"

AppSync lets you build scalable and robust GraphQL API without having to worry about infrastructure. In this session, AWS Serverless Hero Yan Cui shares his personal experience of running AppSync in production - the good, the bad and some tips for dealing with common challenges such as testing VTL templates and overcoming the 500 CloudFormation resources limit.

⭐️Heitor Lessa (@heitor_lessa) - "Lambda Powertools",

AWS Lambda Powertools is a collection of utilities to help customers adopt Serverless best practices, as defined in the Well-Architected Serverless Lens. It eases the adoption of distributed tracing, structured logging, application metrics, idempotency, feature flags, and more. Lambda Powertools is available for Python, Java, and TypeScript (beta).

In this demo session, we'll introduce the core Lambda Powertools utilities, and briefly demonstrate how you can make your applications safer to retry with idempotency.

Heitor Lessa is a Principal Solutions Architect in the AWS Developer Acceleration team covering EMEA. He has spent the last 14 years in various roles focusing on IT infrastructure, cloud operations, business development, developer tooling, and modern application development. Since joining AWS in 2013, he’s been helping Fortune 500 and SMB companies across EMEA with digital transformations, and their respective engineering teams to design cloud native applications following industry-leading practices.

He's the lead author for the Well-Architected Serverless Lens since 2017, lead developer and PM for the AWS Lambda Powertools project, and previously live-streamed Build on Serverless & open_source.init() on AWS Twitch channel.

⭐️Aleksandar Simovic (@simalexan) - "Designing Testable Serverless Applications"

Testing serverless applications has evolved from the first days of serverless. Serverless changed the way we were planning, building, and deploying apps. But it also changed the way we were testing serverless apps. We learned that when using serverless functions we should introduce Hexagonal Architecture.

Hexagonal architecture enables us to design modular serverless functions that can be run and tested locally or in the serverless environment. It also allowed us to write unit tests without complex mocks, and write as many integration tests as you need. As a bonus, our code looks clean and it’s easy to maintain, and hexagonal architecture helps us fight vendor lock-in.

The main goal of this talk is to show how to design testable serverless functions. It starts with an explanation of hexagonal architecture and it’s importance for serverless apps, and it ends with real-world examples using Node.js.
