2026 Java strategy is actually an AI strategy connects Java modernization with AI growth, cloud savings, and runtime efficiency.
I’ve been working with Java since JDK 1.0 in 1996, and I’ve watched the platform absorb every major shift in enterprise computing, from client-server to cloud-native to microservices. But what’s happening right now may be the most consequential transformation yet. According to Azul’s 2026 State of Java Survey & Report, based on responses from more than 2,000 Java professionals worldwide, three forces are converging to reshape the enterprise Java landscape: the migration away from Oracle, the push to control cloud costs, and the rapid integration of AI into production systems. For most companies, these three threads are becoming a single strategic conversation.
The Oracle Exodus Has Momentum
Our survey found 92% of respondents are concerned about Oracle’s Java pricing, and 81% have already migrated, are currently migrating, or plan to migrate their Oracle Java estate to a non-Oracle OpenJDK distribution.
What matters is the mechanism behind that acceleration. When Oracle changed its licensing model, the impact didn’t hit everyone at once. Organizations have multi-year contracts, and what we’re seeing is a rolling wave as those contracts come up for renewal at dramatically higher prices. Some customers received one-year extensions on their previous terms, but those reprieves are now expiring as well. The result is a steady, accelerating flow of enterprises looking for alternatives.
The good news: 84% of those who have migrated say the process went as planned or was easier than expected, and 72% completed their migrations within a year. But the real significance isn’t just the cost savings — it’s what migration unlocks. Organizations that spent years managing licensing uncertainty are now redirecting that budget and attention toward modernization, cloud optimization, and AI. The migration is the starting line, not the finish.
Java: The Production Engine of Enterprise AI
Most people assume AI development means Python. In my experience, the reality on the ground is more nuanced. Our 2026 report found that 62% of organizations now use Java to code AI functionality, up from 50% last year.
When I’m asked why Java is gaining ground here, my answer is scale and integration. Python makes perfect sense for prototyping and model training. Data scientists reach for it because it’s approachable and backed by mature machine-learning frameworks. But when AI moves from the lab to the enterprise, you’re suddenly dealing with massive data volumes, thousands of concurrent users, and the need to embed AI functionality into existing systems — CRM, ERP, accounting, web services — that were built in Java. The developers who already know those systems have the domain expertise to extend them with AI capabilities rather than rebuild from scratch.
Our survey bears this out: 31% of respondents say more than half of the Java applications they build now include AI functionality. That’s a structural shift in how enterprise software gets built.
Cloud Cost Is a Performance Problem, Not Just a Budgeting Problem
Cloud cost optimization is now a universal mandate, with 97% of survey participants taking action to reduce spend, and 41% identify a high-performance Java platform as a top strategy. But the more revealing number is that 74% of organizations have more than 20% of their compute capacity sitting unused. That level of waste has a specific technical cause.
In microservices architectures, individual services need to come online quickly as load fluctuates. But Java applications require warm-up time between cold start and peak performance — a hidden penalty that means they can’t react instantly to demand spikes. To compensate, teams keep spare instances running in the background as insurance: idle but ready. Those standby instances are the unused capacity showing up in the data. Organizations are essentially paying a readiness tax on servers that exist only to avoid performance dips.
This is a solvable problem. Technologies like CRaC (Coordinated Restore at Checkpoint, which Azul contributed to OpenJDK) allow you to freeze a running application at a specific point and restore it almost instantaneously. We’ve demonstrated this with Spring Boot applications where the time to first transaction dropped from four seconds to roughly 40 milliseconds. When you can bring services online that fast, you stop paying for just-in-case capacity and start paying only for actual work.
Dead Code: The Hidden Drag on Everything
Java’s 30-year success means there are production applications that have been maintained and extended for decades. New functionality gets added, but old functionality almost never gets removed, because nobody is confident they can delete legacy code without breaking something. Our survey found 63% of respondents say dead and unused code meaningfully impacts their DevOps team’s productivity, and the security consequences compound the problem.
Dead code expands the attack surface. With 56% of enterprises dealing with Java-related CVEs daily or weekly (up from 41% in 2025), and 30% of teams spending more than half their time on false positives, the burden is substantial. In my experience, these false positives often stem from scanners flagging vulnerabilities in code paths that never actually execute in production. If you can distinguish a real threat from a phantom one at the runtime level, you give your DevOps teams their time back.
The solution requires runtime visibility, not static analysis. Because the JVM controls class loading and method execution, it can track precisely which code runs in production over weeks or months — giving developers the confidence to safely remove what’s dead and dramatically reduce both the maintenance burden and the security noise.
The Year of Decisions
If I had to offer one piece of advice to a CIO or CTO evaluating their Java strategy in 2026, it would be this: look at how efficiently you’re using your resources across your cloud infrastructure, your applications, and your development teams.
The convergence of AI workloads, Oracle migration, and cloud cost pressure means the choice of Java platform carries more strategic weight than it has in years. But most of the gains are available now, at the runtime level, without rewriting a single line of application code. The organizations that move decisively by modernizing their Java estates, eliminating dead weight in their codebases, and reclaiming the capacity they’re already paying for, will be the ones positioned to scale AI without scaling their cloud bills alongside it.
