Reported reasons for not adopting Prime or for churn include:
Sources:
The vendor announced a large-scale Optimizer Hub deployment across a very large number of JVMs with reported cloud cost reductions (vendor press release). This is a vendor-reported result; detailed workload baselines and customer-identifying information were not included, limiting independent verification.

Critical evaluation: Case studies and press releases provide directionally useful information; procurement teams should request named references, workload details, and reproducible benchmark methodology prior to relying on these results.

The organization cannot execute disciplined benchmarking and rightsizing to capture infrastructure savings; without measurement and operational capability, a subscription may add cost without realized benefit.
Minimal tolerance for proprietary dependencies: Prime includes vendor-specific GC/JIT behaviors that can affect portability and migration options.
Developer workflows require native Windows or macOS production parity without additional tooling; Prime is distributed with native Linux support.
Strict requirement for transparent list pricing during initial procurement; Prime pricing is commonly quote-driven and may require sales engagement.

TrustRadius: Prime is listed with an average rating reported on the platform (example: a moderately high score with a small review footprint). Review content on these platforms may require site interaction to view full details.
G2: Prime (Zing) is listed and has reviews; detailed content may require site access.
Gartner Peer Insights: a listing and limited review snippets are accessible; full Gartner content may be restricted in some contexts.
PeerSpot: review summaries indicate generally positive ratings with some reports of production issues in specific cases.
Note: These vendor-supplied statements are included on the product site and are subject to selection bias. Buyers should validate results with independent references and in-house testing.

The vendor support knowledge base documents at least one migration scenario where startup time increased substantially after switching from a different Azul runtime; this demonstrates that migrations can surface regressions that require tuning.
Independent review summaries note that stability can be strong once Prime is properly installed and sized, but that some customers report production issues in certain environments.
Common decision drivers reported across vendor materials and review summaries include:
Sources:
Azul cites commissioned Total Economic Impact (TEI) studies reporting multi-year ROI figures (e.g., older TEI figures and reporting of a newer TEI). These studies use composite organization models and vendor-commissioned interviews; they provide a structured ROI framework but are not direct evidence that a given buyer will realize the same results.
Methodology cautions:
Sources:
Azul Platform Prime (formerly Azul Zing) is a commercial JVM distribution based on OpenJDK and optimized for performance-sensitive Java workloads. Azul positions Prime to reduce garbage-collection-induced latency spikes, improve throughput, shorten warmup, and improve infrastructure efficiency for large or latency-sensitive Java systems. Typical migrations do not require source-code changes or recompilation, although validation is recommended.
Key components/features described by the vendor include:
Note: Vendor performance and ROI assertions should be validated with in-house benchmarks and references.

Typical target organizations are:
Prime is positioned as a commercial, performance-focused offering relative to supported OpenJDK distributions (Azul Platform Core / Zulu, Eclipse Temurin, Amazon Corretto, Microsoft Build of OpenJDK, Red Hat builds), which generally emphasize compatibility and support lifecycle rather than vendor-specific performance features.
