“Switching from Oracle JRE to Azul was as easy as it can get. It’s basically a drop-in replacement.”

Alexander Mueller, CTO

“We found it very easy to do business with Azul. Azul’s business model and terms were very flexible, and they helped to simplify our operations by removing constraints.”

Michihiro Okada, General Manager of Software R&D Division

“Azul provides a well-supported, reliable and secure Java JDK and runtime that we use in many of SAS Institute’s products and solutions. The satisfaction of thousands of SAS customers demonstrates the quality of the Azul Platform.”

Sam Penfield, Product Manager

Michael Thalhammer, Head of Software Development

“By adopting Azul Platform Core and teaming with Azul, we ensure that our customers always have access to secure, certified, and tested builds of Java.”
