AI-First Java Meets Enterprise Challenges

Azul Prime is a high-performance Java platform that provides superior speed, start-up and warm-up, and consistency vs. other OpenJDK distributions to increase responsiveness, optimize compute and boost operational efficiency – all without recompiling or changing application code.

prime-1

Application Performance & Latency Improvement  

Improve responsiveness, maintain consistency, and meet performance SLAs as load increases across custom code and the Java infrastructure it depends on, including Kafka, Cassandra, and Elasticsearch. 

  • Real-time code optimization: an LLVM-based JIT compiler that built to outperform standard OpenJDK 
  • Accelerate JVM Warm-up: instances run at full speed immediately, even under bursty, unpredictable traffic. 
  • 2x-5x Higher Throughput: more transactions on the same infrastructure, without pauses, jitters, or timeouts. 

No code changes. No recompiling. Full Java TCK compliance. 

prime-3

Cloud Cost Optimization 

  • Lower cloud compute costs by 20%+ for existing workloads from faster Java code execution, quicker warm-up and more efficient compute utilization 
  • Handle more transactions on the same infrastructure, allowing you to scale cost-effectively. 
  • 129% 3-year ROI with payback in under 6 months  
prime-2

Absorb Agentic AI Demand 

AI runs on GPUs but stresses existing systems based on Java. LLM calls, RAG retrieval, and agentic workflows are run against Java-based applications and infrastructure. 

  • Higher throughput per core, up to 50% fewer compute cores 
  • Faster & predictable tail latency under load 
  • Fast startup and warm-up for instant, elastic scale 
prime-4

Higher DevOps Efficiency & Code Velocity

Operational complexity from AI workloads, expanding cloud, and security demands keeps growing. AI codegen has hit mainstream production scale, generating code faster than runtime can keep pace. 

  • Simplifies JVM tuning and cuts operational tickets. 
  • Achieves the highest performance for verbose, allocation-heavy AI code

Forrester TEI Report 26 Zoom Team Background

Forrester Consulting: “Azul Prime Achieves 129% ROI.”

Forrester Consulting’s Total Economic Impact™ (TEI) study, commissioned by Azul in March 2026, examines how six enterprise Azul Prime customers reduced cloud compute instances and data center server counts, and improved developer productivity — all while driving down operating costs.

“Without Azul Prime, we would be running five times more infrastructure. Azul has allowed us to focus only on our applications. We don’t have to worry about performance.”

Cody Bayer, DevOps Engineer

“Now, our engineering team is able to ignore performance maintenance and spend all their time building features. Yet, we’re a thousand times faster than your typical payment transaction or website. Azul Prime is a big part of the reason for this.”

Brett Vasconcellos, CTO

“Having a product that I don’t have to adjust and change and modify and work with and turn a bunch of switches and dials, has been great, and the support has been excellent. The best that I’ve ever dealt with.”

Ted Boehm, Chief Platform Architect

“Azul Prime allows us to free up a lot of monetary resources to invest in other aspects of the company as well as other new upcoming products.”

Ariel Pisetzky, VP of IT

“I’m just as enthusiastic today about Azul Prime as when I started out with the product ten years ago as a performance engineer. Azul removes the toil in operations.”

Attila Bukta, Sr., Director of OMS Service Reliability Engineering
