Lean Spring Boot Applications for The Cloud


Patrick Baumgartner works as a passionate software crafter, technical agile coach, and trainer at 42talents. He works with people to create beautiful and simple solutions and enjoys building software for the cloud with Java, the Spring ecosystem, Neo4j and ElasticSearch and other open-source technologies.

Learning new stuff from others and with others is a thing Patrick enjoys very much. Because of this, he is actively involved in the software crafters, Java and Spring, and the agile community. He likes to make a difference, running experiments, and having discussions with a wee dram.


With the starters, Spring-Boot offers a functionality that allows you to set up a new software project with little effort and start programming right away. You don’t have to worry about the dependencies, since the “right” ones are already preconfigured. But how can you, for example, optimize the start-up times and reduce the memory footprint and thus better prepare the application for the cloud?

In this talk, we will go into Spring-Boot features like “spring-context-indexer”, classpath exclusions, lazy spring beans, and actuator. In addition, we’re also looking at switching to a different JVM and other tools.

Let’s make Spring Boot great again!
