Database driven applications in the cloud

 There are a lot of great tutorials out there on how to build applications based on AWS and in particular on Amplify. But I wanted to try out by myself how much effort it is, to build an application that is a bit closer to a real business desktop app meeting the following requirements: Serverless architecture Based on an RDBMS (relational database) Performing CRUD operations on entities Authentication and authorization Sound exception handling The result is an application serving currently one entity that can be queried and updated.

Then I was took the the role of an AWS solution architect to move an existing application to the cloud which also means an almost full re-implementation. In respect of AWS and data-driven applications, I encountered a lot of very interesting features. I will discuss some of them here in the blog in the near future, so please stay tuned!
