GlassFish is an open-source application server framework first developed at Sun Microsystems (now part of Oracle) to support the Java EE (Enterprise Edition) platform. Designed to handle large-scale applications, GlassFish provides mature scalability and management features while using a small memory footprint. Its extensible core is based on OSGi Alliance standards. Doubling as a web server, GlassFish’s servlet container is an offshoot of Apache Tomcat. Its Grizzly component leverages Java New I/O (NIO) for greater scalability and processing power. In addition to its built-in features, GlassFish offers support for high availability clustering and load balancing, and comes with an intuitive Administrator Console for easy configuration and management. For developers and operations teams building and managing applications with the GlassFish application server, the AppDynamics platform provides a comprehensive solution for monitoring and managing the performance of your Java applications. With rapid installation and the most scalable architecture in the industry, AppDynamics solutions help you deploy your applications more quickly and with more confidence.
