AWS Gameday with Red Hat Ansible
AWS GameDay is an interactive team-based learning exercise designed to give players a chance to put their DevOps skills to the test in a real-world, gamified, risk-free environment. Most importantly, it is an extremely fun way to learn more about working with cloud technology without the step-by-step instructions provided in workshops or classroom-style sessions. If you are seeking an open-ended, and at times ambiguous, style of training then GameDay is the perfect challenge for you.

Java code instrumentation for beginners
Curious about how profilers can estimate the time spent in each method or follow memory allocations?

One of the most common ways is to use instrumentation. Instrumentation is the addition of code to methods for the purpose of gathering data. Profilers inject code into the software under test and extract information for performance analysis. Agents and event loggers also use this strategy.

In this workshop we will go over the basics of JVM, Java bytecode, Java agents, and code instrumentation. By using the Java Instrumentation API, we will build a simple “profiler” that counts the number of times a particular method was invoked. You will learn how to inject code into a Java application and follow the path of the instrumentation to see in detail the way it works.

Basic knowledge of Java is required.
