Optimizing Spring Boot Apps for Cloud
Two days optimizing Spring Boot applications for the cloud – lower memory and CPU usage, shorter startup times, higher throughput, and lean OCI containers.
Spring Boot simplifies the creation of new projects with its starters, eliminating the need to worry about dependencies – the right configurations are already pre-set. But how can you optimize an application for the cloud? This workshop presents various strategies to achieve efficient resource utilization, faster startup times, and improved performance in cloud environments. You will learn hands-on approaches that will enable you to optimize your Spring Boot applications specifically for cloud deployment.

More about Cloud Native Spring Boot
Optimizing Spring Boot applications for the cloud is a central topic in modern software development today. Technologies such as GraalVM Native Images, Virtual Threads (Project Loom), App CDS, and Project Leyden make it possible to drastically reduce startup times, minimize memory consumption, and maximize throughput. The goal is to run Spring Boot applications efficiently, scalably, and cost-effectively in cloud environments.Further resources:
History
The cloud-native trend emerged with the rapid adoption of container platforms like Kubernetes and the growing use of serverless architectures. Early Spring Boot applications suffered from long startup times and high memory consumption – characteristics historically accepted in the JVM ecosystem but that become cost drivers in cloud-native environments.
With the integration of GraalVM Native Image into Spring Boot 3.0 (November 2022), the framework gained first-class support for compilation into native executables that start in milliseconds. Complemented by Project Leyden, Virtual Threads, and Application CDS, Spring Boot continues to evolve into the preferred platform for high-performance, cloud-optimized Java applications.
