Agenda

With mock-server you can do just that. Mock-server lets you mock any http service, making you independent of other teams building those services. And the best part is, you can use it with the tools you already know like JUnit, Maven and Docker and do all the things you already know from your favorite Java mocking framework. You can run mock-server locally, as part of your Maven build or as a Docker image in your cloud environment. In this session I will show you exactly how you can use mock-server for your tests.

But nowadays, the Cloud is becoming ubiquitous. Containerization is the way to go to alleviate some of the vendor lock-in issues. Kubernetes is a de facto platform. If a container needs to be killed for whatever reason (resource consumption, unhealthy, etc.), a new one needs to replace it as fast as possible. In that context, the JVM seems to be a dead-end: its startup time is huge in comparison to a native process. Likewise, it consumes a lot of memory that just increase the monthly bill.

What does that mean for us developers? Has all the time spent in learning the JVM ecosystem been invested with no hope of return over investment? Shall we need to invest even more time in new languages, frameworks, libraries, etc.? That is one possibility for sure. But we can also leverage our existing knowledge, and embrace the Cloud and containers ways with the help of some tools.

In this talk, I’ll create a simple URL shortener with a “standard” stack: Kotlin, JAX-RS and Hazelcast. Then, with the help of Quarkus and GraalVM, I’ll turn this application into a native executable with all Cloud/Container related work has been moved to the build process.

The audience will take away why, how, and where to use the new language features like Sealed Classes and Interfaces, Records, Text Blocks, Pattern Matching for instance of and much more that will transform your everyday coding experience. You’ll see for yourself if it is worthwhile adopting all these new features.

Spring Boot has revolutionized the Java space and continues to do so, evolving constantly to increase developers' superpowers and advance the state of production-grade software development.

Presenting a dynamic technology before vastly different audiences often limits what can be proposed & presented. Let’s fix that!

This session is an omakase, a "chef’s choice" of key points and latest/coolest capabilities for developers in the Spring Boot ecosystem. Known by French chefs as m’étonner ("Astonish me!"), the goal is to combine useful patterns and new possibilities in one fast-paced live-coding adventure from which everyone leaves with something tasty to chew on. Come for the apps, stay for dessert, leave satisfied & excited for the next "course" of production software!

You are also invited to take our technical Masterclass quiz, which will be active for only 2 hours, starting at 12:00 AM. The winners will be announced at 15.00 PM. You can win one of  1500 lei Emag vouchers or 3* 500 lei Emag vouchers. The Quiz is available here: http://www.quiz-maker.com/QC5DA57YQ 

A few years ago in order to solve this problem, R2DBC specification was created, which is based on reactive stream specification types and allows non-blocking, backpressure-aware database access. Since then an ecosystem has started to appear and evolve around it.

In this talk, I will show what R2DBC specification and the surrounding ecosystem can offer and share our experience of building a solution based on R2DBC and delivering it to the production.

When, additionally, you're part of the telecom world, choosing the right technology is important to ensure a stable development baseline, for a longer period of time, able to provide the required stability and performance (tier 1, millions of end-customers, up-time in the high 9s, etc).
