Enterprises in regulated sectors like finance and healthcare face a constant tension: how to embrace cloud-native performance gains while meeting strict data privacy and compliance requirements. JVM optimization often raises concerns—if performance data is shared across environments, does it risk exposing sensitive information?

In this clip from Java Reloaded, John Ceccarelli, VP of Product Management at Azul, explains how Optimizer Hub addresses these concerns by design.
Not a SaaS Service
“The first thing that’s important is that Optimizer Hub is not a SaaS product,” Ceccarelli emphasized. Unlike cloud-hosted solutions that require sending code or data to external servers, Optimizer Hub runs inside the customer’s own Kubernetes cluster. Enterprises retain full control over deployment, typically setting up one hub per geo and routing workloads accordingly. High availability can be achieved either across geos or within a single environment.
Minimal Data Transmission
What actually flows between JVMs and the hub is minimal. “We’re really just talking about method names,” Ceccarelli said. The only theoretical risk of sensitive data exposure would come from constants required for compilation context—and even that is rare. The result is an extremely low probability of transmitting personally identifiable or regulated data.
Security Boundaries Intact
Because the hub runs within the enterprise’s own environment, none of this data crosses external firewalls. For organizations with stringent DMZ requirements, it’s even possible to set up multiple hubs to isolate workloads by group or domain.
Practical for Regulated Industries
For enterprises hesitant to adopt performance optimization due to compliance concerns, Optimizer Hub offers a middle ground: full optimization benefits, delivered securely inside the enterprise boundary. As Ceccarelli noted, customers across industries have already validated this model, and concerns about sensitive data exposure have been rare.
By eliminating warm-up delays while keeping all operations inside the customer’s Kubernetes environment, Optimizer Hub shows that performance and compliance don’t have to be at odds.
