Join us for an intensive, practical workshop exploring Amazon & AWS's proven strategies for modernizing Java applications at scale. Drawing from real-world experience migrating thousands of Java applications, this session will demonstrate how organizations can successfully transition from JDK 8 to modern Java versions and also more advanced migrations and modernization challenges.

You will transform a Java 8 to Java 21 using step-by-step migration and full automated agent transformation and also optional hands-on lab for frameworks migration and paradigm shift creating MCP tools for existing codebases.

Key Learning Outcomes:

Understand the business case for Java modernization, including concrete examples of 40% memory reduction and 90% improvement in cold start times
Prepare your codebase creating lacking documentation, dependency mapping and leadership reports using AI
Master different migration approaches, from simple runtime switches to frameworks migration and paradigm shifts like REST to MCP
Learn to leverage opensource and AI-powered tools for code transformation
Gain hands-on experience with practical modernization tools including OpenRewrite, Amazon Q CLI and AI transformation agents

Workshop Highlights:

Live demonstrations of legacy code analysis and transformation
Practical guidance on monolith refactoring and dependency management
Best practices for future-proofing Java applications

"Friends don't let friends to run JDK8!"
