Understanding JVM Architecture

Understanding JVM architecture and how Java really works under the hood is an important learning for every Java developer in order to effectively make use of the Java ecosystem. This blog post series will provide you with a solid foundation on JVM internals and technologies around the Java ecosystem.

Background

Designed in 1995 by James Gosling for Sun Microsystems, Java is a multi-paradigm (i.e. object-oriented class-based, structural, imperative, generic, reflective, concurrent) programming language which is loved by millions of developers. On any given ranking index, Java becomes the most popular language for the past 15 years. Tens of thousands of enterprise applications developed in the last 15 years have been mostly written in Java, making it the language of choice for building enterprise-grade production software systems.

Even though I have been using Java since 2015, I recently realized the power of Java ecosystem while doing my final year undergraduate research on Java performance aspects and it motivated to dig deeper into the world of Java. I am planning to write a series of blog posts related to Java internals, performance profiling, server tuning, and many more interesting topics and kindly invite you to stay in touch with this blog. And that’s it for now. Let’s start from primers on Java fundamentals!

Java Environments

For almost any programming language, you need a specific environment which comprises of all the necessary…
