OpenJDK is a free and open-source implementation of the Java Platform, Standard Edition. It is the result of an effort Sun Microsystems began in 2006. The implementation is licensed under the GNU General Public

Cognosys provides hardened and ready to run images of Open JDK on cloud ( AWS marketplace and Azure).

Deploy Open JDK securely on cloud i.e. AWS marketplace and Azure and Google Cloud Platform (GCP)

Major Features Of Open JDK

• Lambda Expressions, a new language feature, has been introduced in this release. They enable you to treat functionality as a method argument, or code as data. Lambda expressions let you express instances of single-method interfaces (referred to as functional interfaces) more compactly.
• Method references provide easy-to-read lambda expressions for methods that already have a name.
• Default methods enable new functionality to be added to the interfaces of libraries and ensure binary compatibility with code written for older versions of those interfaces.
• Repeating Annotations provide the ability to apply the same annotation type more than once to the same declaration or type use.
• Type Annotations provide the ability to apply an annotation anywhere a type is used, not just on a declaration. Used with a pluggable type system, this feature enables improved type checking of your code.
• Improved type inference.
• Method parameter reflection.
