Who this course is for

Mid and Senior-level Engineers

The program is designed for specialists working with high-load Java systems, aiming to gain a deeper understanding of JVM behavior.

• Java developers and architects: For those who want to understand the internal mechanisms of JVM and write truly fast, stable, and scalable code.
• QA Performance Engineers: For those who strive to identify bottlenecks in applications before they reach production.
• SRE / DevOps Engineers: For those responsible for production stability and want to reduce the time taken to diagnose critical incidents.

Skills and learning outcomes

In-depth understanding of the JVM

• JVM Architecture: Threads, heap, metaspace, native memory, JIT, and HotSpot optimizations.
• GC mechanisms: Algorithms, types of collectors, pause analysis, and optimization for specific loads.

Practical optimization

• Garbage collection tuning: Reducing GC pauses, optimizing throughput and latency.
• Application scaling: Approaches that truly work when increasing load.

Professional data analysis

• GC logs: Learn to find causes of sharp pauses and latency spikes.
• Thread dumps: Identifying deadlock, contention, long-running operations.
• Heap dumps: Finding memory leaks, analyzing object states and their relationships.

Working with real cases

• Analysis of incidents from large companies: What happened, why, and how it was fixed.
• Diagnostic templates: Universal approaches applicable in any JVM environment.
• Identifying bottlenecks: Techniques for detecting “bottlenecks” in code and infrastructure.
