– 1 GlassFish instance is capable of processing all requests

5. How GlassFish Can Improve
• JMS, EJB Timer, Caching (Java EE 7)
• Domain-specific standards: many companies, active in the same area,
can share “libraries” and focus on specific projects on top of these
libraries
• interaction between developers
• Share code and ideas
