REST becomes the ultimate solution for text-based-integration over HTTP. This seminar details SpringMVC and Spring WebFlux for dealing with REST / Reactive REST and create unit tests for Web-Services.

Microservices allows to architecturally isolate each service and by that create an integrated applications in which pieces of code can be separately administrated, tested and enhanced. Serverless is a native avolution of SaaS to be more accurate via Function as a Service (FaaS) / Serverless. The seminar explores SpringCloud+Boot for implementing Microservices and for Serverless deployments.

GraphQL APIs with Java backend- Guest speaker

GraphQL is a technology for specifying and implementing rich and mature APIs. It was introduced by Facebook but has since been taken up by many software companies including GitHub, Twitter, PayPal and Atlassian. In this session we’ll explore the elements of GraphQL, map out considerations for a successful API and contrast GraphQL with with REST. To complete the picture we’ll go through the details of a Java implementation.
