Apps modernization strategy: a light at the end of the tunnel by Karina Varela

Think of that one legacy service in production. Well, you've just been asked to add new functionalities to it. You can already predict the pain in this modernization:

code changes are ineffective and error-prone, and rewriting may ask for insane amounts of work;
you can't move it to cloud environments due to high predictable costs;
if creating new services, you must overcome the challenges of handling data in distributed systems (e.g., dual-write, eventual consistency, distributed transactions)

Luckily, you can join this talk and see the way out!

In this session, we'll explore a modernization strategy with the outbox pattern. Event-driven technologies and cloud adoption boosts this architecture's solution through enterprise data integration patterns - consequently opening new possibilities for your use cases deliveries.

Let's run through an actual implementation to learn how change data capture (CDC) allows extending apps by immersing them - with zero code changes - within a cloud-based event-driven microservice architecture. This CDC on steroids relies on cloud-native technologies like Kafka, Kafka Streams, Quarkus, Camel, and OpenShift.

Best of all: You can leave this session with extra architectural knowledge, a complete architectural technical guide, a step-by-step guide to trying the solution and getting your hands dirty, and finally, feeling confident to apply it in your context when needed.

It's time to gear up and extend your existing tech stack!
