Azul Platform Core vs Free OpenJDK

5 Reasons to Choose Azul Platform Core

The comparison table below summarizes how Azul Platform Core offers significant advantages over free builds of OpenJDK.

Azul Platform Core provides a secure, stable, and affordable option for enterprises seeking to ensure operational stability, enhance security and compliance, achieve cost efficiencies, and guarantee their IP is free from contaminating software for their critical Java infrastructure.

Improved ​Security & Compliance

• Critical Patch Updates (CPUs) — updates whose only recent changes are security related — are delivered on a firm SLA. ​
• Only Azul and Oracle offer CPUs — this is a key benefit of commercial support​.
• CPUs provide protection from high-risk exposure that occurs when instability in a full update prevents the application of new security patches (this occurs in roughly 20% of quarterly releases).​
• Azul’s track record for timely delivery of CPUs goes back to 2014.​
• To date, Azul’s CPUs have never experienced a regression.
• Azul backports security fixes for all Azul supported versions, including Java 6 and 7. 
• Full updates also known as Patch Set Updates (PSUs) are available on a best-effort basis.​
• PSUs regularly require ​additional, out-of-cycle bug fixes to address issues introduced by new builds. These issues can interrupt business operations. For example, Hadoop clusters and Solr/Lucerne were unable to run after the 8u262 update.
