BellSoft built a business around the part of Java most companies would rather not think about. Its pitch is simple: one engineering team for the runtime, the Linux layer and the container - with fewer licensing surprises and fewer vulnerabilities to chase.
Azul is the largest independent Java vendor and a major contributor to OpenJDK. It builds production-grade Java runtimes - Azul Platform Core (certified OpenJDK builds) and Azul Platform Prime (a high-performance JVM) - plus the analytics-driven Intelligence Cloud. Companies use Azul to escape Oracle Java licensing costs, run lower-latency applications, and cut cloud spend.
