Don't let this gap widen
Companies that ignore GraalVM lose up to 40% performance on startup times and consume twice as many cloud resources.
This inefficiency creates significant annual cost overruns and delays product launches.
Developers without these skills see their employability drop amid rising demand for native technologies.
Acting now avoids these concrete risks and secures your professional position.
Participants discover GraalVM in a professional context, install the environment, and compare performance with HotSpot. They complete practical exercises on business cases, generate initial native executables, and analyze key metrics to optimize startup times.
This day deepens native compilation with GraalVM. Learners use native-image on real projects, configure advanced options, and perform size reduction exercises. They produce measurable deliverables and integrate best practices for enterprise applications.
Trainees integrate GraalVM with major Java frameworks. They develop microservices, test compatibility, and optimize containerized images. Real business cases enable delivery of functional prototypes with measured performance.
This session trains participants in GraalVM diagnostic tools. Participants configure monitoring, analyze memory leaks, and use dashboards. They handle real scenarios and produce optimization reports for their professional projects.
Learners complete their training by deploying GraalVM applications in a production environment. They implement CI/CD pipelines, apply security rules, and measure gains. Each participant delivers a complete project optimized for the enterprise.
The Training GraalVM 2026 - Optimizing Java 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.
The trainer alternates between demonstrative, interrogative and active methods (through hands-on labs and/or scenarios). This pedagogical approach guarantees concrete learning that's immediately applicable at work.

Before, during, after: we frame the brief, introduce the trainer, tailor the content and measure impact. You stay in control from kickoff to wrap-up.
Each trainer is validated on three criteria: hands-on field expertise, proven pedagogy and alignment with your industry.
30-minute video call between you and the selected trainer to validate the fit, adjust content and clear any final doubts.
No recycled slides. The syllabus is reworked from your real cases: tools, constraints, vocabulary, ongoing projects.
Live evaluations, 30/90/180-day check-ins and a consolidation plan. If the impact misses the mark, we rework it.
A simple promise: you don't pay to discover the trainer on day one. Everything is validated upfront, by you.
