The JVM Ecosystem and Alternative JVMs
The JVM is the cornerstone of Java’s write once, run anywhere philosophy, enabling the execution of Java bytecode on diverse platforms. While the HotSpot JVM has long been the stalwart choice, the expansive JVM ecosystem extends far beyond, offering alternative implementations that cater to specific needs and performance considerations. In this chapter, we’ll explore the JVM landscape comprehensively, delving into alternative JVMs such as OpenJ9 and Correto. As we unravel their nuances, you will gain valuable insights into the diverse options available, each with unique features, optimizations, and trade-offs.
Our journey commences with an in-depth overview of these alternative JVMs, shedding light on their architectures and critical differentiators. Subsequent sections delve into the performance characteristics and benchmarks that distinguish these implementations, providing a nuanced understanding of how alternative JVMs stack...
