Memory management remains the primary factor for application performance in enterprise Java environments. Between 2017 and 2025, the ecosystem shifted from manual tuning to architectural selection. Industry data suggests that 60 percent of Java performance issues and 45 percent of production incidents in distributed systems stem from suboptimal Garbage Collection (GC) behavior. This guide provides a strategic framework for selecting collectors based on workload characteristics. It covers the transition from legacy collectors to Generational ZGC, analyzing trade-offs regarding throughput, latency, and hardware constraints with mathematical precision.

Java 8 to Java 17

Java, the widely-used programming language, as it continues to evolve with each new release I still see companies and projects hesitating to transition from Java 8 to Java 17, the latest long-term support (LTS) release. This leads them into either using unsupported Java 8 versions or paying a heavy fee for support or for the usage of an alternative VM like Azul. The transition from Java 8 to Java 17 has brought about numerous enhancements and features that developers can leverage to create more efficient and robust applications. In this article, we will delve into the new features introduced in Java 17, compare them with Java 8, and provide best practices for migrating from Java 8 to Java 17.
