Serverless Bytes

30-minute virtual workshop for serverless applications

Learn how to build a weather app with AWS AppSync, GraphQL & AWS Lambda


Are you looking to get started building apps without managing servers? And do you love to code?

Join a 30-minute live stream on Twitch and get a hands-on intro to serverless applications by building a weather app which provides weather information for popular travel destinations. We will use AWS AppSync to fetch location data from a DynamoDB table. With the query result we will trigger an AWS Lambda function and pull current weather data for the respective locations through an open weather API.

Our Senior Developer Advocate, Chris, and Specialist Solutions Architect, George, show you how to use AWS Developer tools like AWS Cloud9 and answer your questions in real-time.

AWS services you will use


Develop, test, and deploy your serverless application in the IDE of AWS Cloud9.


Specify data requirements and request data from the cloud with GraphQL.


Use AWS Lambda for serverless data processing.


Host your web application's static assets on Amazon S3.


Save data in a NoSQL database with Amazon DynamoDB.

What is Serverless Computing?


Serverless computing allows you to build and run applications and services without thinking about servers. Serverless applications don't require you to provision, scale, and manage any servers and you can build them for nearly any type of application.

AWS Lambda is one of the main services in serverless apps. You just need to upload your code and Lambda takes care of everything required to run and scale your code.

The AWS Twitch experience


Serverless experts Chris and George will show you how to develop the serverless app in our AWS Cloud9 IDE. You can ask questions through the Twitch live chat which our presenters and chat moderators will answer you in real-time.

The series "Serverless Bytes" provides short, getting started workshops for basic serverless topics. You can find further episodes and other series on our AWS Twitch channel >>
