“Switching from Oracle JRE to Azul was as easy as it can get. It’s basically a drop-in replacement.”
“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.”
“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.”
“Azul was a drop-in replacement and migration has taken less than three months. Had we known how seamlessly and smooth the process would be, we would have switched from Oracle Java to Azul Java much earlier on.”
“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.”
