In the past 20 years I’ve been able to work with many developers. Together we’ve worked on very large to the tiniest of projects, from huge corporate applications to simple web forms that deliver enormous business value. From beautiful new ‘greenfield’ applications to software written long before I was born.

Concurrency in Kotlin: how coroutines make it easier

Concurrent software is hard to get right, as we’ve seen in the previous article, “When flows split”. Concurrency is even harder to express. Most concurrent code is being written in a way that makes our heads spin every time we need to read it. Let us see how Kotlin helps us write concurrent code that is clearer and more efficient from the start.

When working on microservices in the Java ecosystem, especially using Spring (Boot), you will notice the long start-up time that applications will have, let alone the high memory consumption they will have. The overhead of each single microservice will eventually take its costs on the system. Looking at a framework such as Micronaut could help out to reduce this overhead without loosing any developer’s productivity. Not only “classic” applications can be built using Micronaut, but also serverless applications, functions, can be built and deployed on a cloud environment or on Kubernetes using OpenFaaS. Let’s dive into it!
