AWS DevDay Berlin 2019 - Simplify your Web & Mobile apps with cloud-based serverless backends

Designing, deploying and maintaining APIs for your mobile application is a challenge. In between authentication, authorization, data access, notifications, offline devices and the usual non functional requirements of availability, scalability and shrinking budgets.During this session, I will show you how to deploy a GraphQL API, without requiring to be an API expert. I will show you how to easily integrate an authentication wall, with minimal coding. By attending this session you will be able to accelerate the development of your web & mobile applications by using simplified backends in the cloud.
