Format
In Zürich, on-site at your office, or fully remote. We adapt exercises and tooling to your environment.
Spring Boot Performance Training
Take a measurement-led approach to performance in the Spring Boot services you operate. Profile startup and memory use, examine AOT and GraalVM native images, and practise tuning with Actuator and Micrometer rather than relying on assumptions.
One- to two-day in-house course for up to 12 participants. Delivered in Zürich, at your office across Switzerland or Europe, or fully remote; scope is focused on the performance questions and Spring Boot versions relevant to your team.
When This Training Is Worth Your Team's Time
For CTOs and engineering managers who have a specific Spring Boot performance or resource question and want the team to investigate it systematically.
-
Startup or Memory Is a Constraint
Service startup, memory use, or container resource limits are affecting deployment or operating decisions.
-
Native Images Are Under Evaluation
The team needs to understand GraalVM native image benefits, constraints, build changes, and maintenance trade-offs before choosing a direction.
-
Tuning Is Based on Assumptions
Engineers need shared profiling and observability techniques before changing framework, JVM, connection-pool, or thread-pool settings.
What You Will Learn
Participants measure where Spring Boot spends time and memory, then compare tuning options and their maintenance trade-offs.
-
Startup Performance
Measure and reduce startup time using lazy initialisation, Spring's AOT engine, class data sharing, and Spring Boot's build tools integration.
-
Memory Footprint
Profile heap and off-heap usage, reduce unnecessary bean creation, and configure JVM settings appropriate for containerised workloads.
-
GraalVM Native Images
Compile Spring Boot applications to native executables with GraalVM, measure the effect on startup and memory, and understand the trade-offs.
-
Observability & Tuning
Use Spring Boot Actuator, Micrometer, and structured logging to observe, measure, and continuously improve application performance in production.
Who Is This Training For?
This training is for teams running Spring Boot applications in production who want measurable improvements in performance and resource efficiency.
-
Backend Engineers
Developers responsible for the performance of their Spring Boot services who want to use profiling evidence to choose and verify tuning changes.
-
Platform & DevOps Teams
Teams optimising container images and resource budgets in Kubernetes or cloud environments where startup time and memory costs matter.
-
Architects
Engineers evaluating GraalVM native images or AOT compilation for their stack and needing a grounded, practical introduction to trade-offs.
