Don't let this gap widen
Companies that ignore GraalVM lose up to 40% performance on their Java applications.
Statistics show that 65% of modern architectures demand drastic cuts in memory consumption.
Without these skills, developers risk significant professional setbacks against the competition.
Skipping this certification training exposes the company to unnecessary infrastructure costs and rapid technical obsolescence.
Participants explore GraalVM in depth with practical exercises on native compilation. They work with tools such as native-image, analyze concrete optimization cases and produce an initial deliverable of a converted Java application. The training emphasizes measurable performance gains for professional projects.
This day covers the polyglot use of GraalVM with JavaScript and Python. Learners perform integration exercises, optimize execution contexts and deliver a multi-language prototype. The pedagogical approach combines theory and concrete workshops tailored to the needs of modern enterprises.
Trainees master GraalVM's advanced profiling tools to identify bottlenecks. They work on real company cases, adjust configurations and produce detailed optimization reports. The training includes practical sessions to validate improvements in latency and memory consumption.
The final day focuses on the secure deployment of GraalVM applications in production. Participants configure containerized environments, test resilience and finalize a complete deliverable ready for enterprise use. Feedback and best practices conclude the certifying training.
The Training GraalVM - Optimizing Native Performance program is delivered onsite or remote (blended-learning, virtual classroom, remote presence). At Learni, an industry-certified training organization, every program is built to maximize skills acquisition regardless of the chosen format.
