On my serverless journey, I had a closer look at the technologies around. Since I have been implementing applications with Spring for many years, it was natural to try Spring Cloud Function. Let's have a closer look at how a serverless function running as Azure Function can be implemented with Spring.

Stripe uses webhooks to notify about events like successfully finished payments. While integrating Stripe for the first time, I asked myself how such webhooks can be tested properly without relying on Stripe during automated test execution. In this blog post you will learn how it works.

Azure Functions support several runtime environments including the Java Virtual Machine, which allows us to implement functions in programming languages like Java and Kotlin. Let's have a look at how a simple Azure Function can be implemented with Java.

The idea of an API-first approach is to treat APIs as first-class citizens by building the software product around APIs. Formal specifications serve as the contract and define, what the consumer can expect from the API. To ensure consistency of the contract and the implementation, some parts of the source code can be generated from the specification document.

A regular task in the life of a software developer is to choose appropriate tools for specific use cases. That's why I would like to have a short look at several tools which I already used for testing REST APIs. To be more concrete, it's about cURL, JMeter, SOAP UI, Swagger UI, Postman and IntelliJ Idea.
