Mark Heckler is a software developer & Principal Cloud Developer Advocate for Java/JVM Languages at Microsoft, conference speaker, Java Champion, and Kotlin Developer Expert focused on developing innovative production-ready software at velocity for cloud and edge computing platforms. He has worked with key players in numerous industries and public sector organizations to develop and deliver critical capabilities on time and on budget. Mark is an open source contributor and author of Spring Boot: Up and Running (https://bit.ly/springbootbook) and can be found on Twitter @mkheck.

In this session, you'll learn how to leverage proven patterns & open source software to rapidly build a robust portfolio of microservices that provide a solid foundation for your dynamic and growing microservice architecture, then learn how to make the cloud do it for you so you can focus on your customers' needs. This session addresses vital points such as:

+ Configuration services

+ Microservice registration and discovery

+ Features for system resilience

+ Intelligent routing

+ Secure secret keeping

And more, depending on time available

The presenter will demonstrate how to develop, deploy, and manage microservices with tools employed by industry leaders to build resilient, scalable, & available systems using Spring Cloud and Azure, but all concepts and constructs shown apply to various frameworks and cloud platforms.


Spring Boot streamlines Java and Kotlin development with its developer-first focus. By simplifying dependency management and deployment, providing unmatched autoconfiguration capabilities, and leveraging convention over configuration at every opportunity, developers can focus nearly all of their efforts on designing, developing, and delivering amazing software. This is the happy path, and it is wide.

Good developers write good code, but great developers can diagnose the inevitable issues that arise in complex software systems. When your code takes the road less traveled, how can you quickly identify, isolate, and resolve the problem, not the symptoms? How can you move from good to great?

In this session, the presenter will take you on a live-coding adventure(TM) into the hidden passageways of your Spring Boot application. Topics covered may include (but are not limited to) the following, depending upon time available:

  • Application startup, including autoconfiguration steps/process
  • Bean initialization and configuration
  • Debugging local apps via IDE
  • Remote debugging container applications
  • Tracing distributed apps
  • Debugging reactive code

Come to this session to get a deeper understanding of your Spring Boot apps and level up your debugging skills!


On the right corner, Quarkus, goes into his challenge against Micronaut the lightweight champion, and pound-for-pound with Spring Boot the best microservice framework in the world. Who will win the world “Cloud Native Java Runtime” title fight?

In this 3h long workshop you will bring your own laptop, install all the needed tools and be ready to develop from scratch three microservices: one written with Quarkus, one with Spring Boot and one with Micronaut. Add some business logic, access a database in a reactive and imperative manner, run them on HotSpot, compile them with GraalVM, containerize them with Docker and deploy them to the cloud. Then, add some load testing, scale and monitor them. At the end of this workshop you will know which of these microservices is the most appropriate in terms of performance, resource consumption, and startup time… or maybe you won’t ;o)

For this workshop you will need to install:

  • Git
  • Java 11, Java 17 and GraalVM
  • Your own IDE
  • Docker desktop
  • An HTTP client (cUrl, wget, Postman)
  • Have a Docker Hub account
  • Have a GitHub account
  • Have an Azure account (we will give you some credits)
