Glassfish features and specs

• Open Source
  GlassFish is open-source, allowing developers to access and modify its source code. This promotes collaboration and continuous improvement by the community.
• Enterprise Features
  It offers a range of enterprise-level features such as EJB, JPA, JMS, and web services, making it suitable for building complex applications.
• Java EE Reference Implementation
  GlassFish is the reference implementation of Jakarta EE (formerly Java EE), ensuring adherence to standards and compatibility with other Java EE technologies.
• Modular Architecture
  Using OSGi modules, GlassFish allows for a high degree of customization and the ability to deploy only necessary components, enhancing performance.
• Admin Console
  It features an intuitive and user-friendly administrative console, simplifying the management of server instances and deployed applications.

Possible disadvantages of Glassfish

• Performance Overhead
  Compared to other application servers, GlassFish might encounter performance issues under heavy load due to its extensive feature set.
• Complex Configuration
  Configuring GlassFish can be complex and time-consuming, especially for beginners, due to its numerous configurable options.
• Lower Adoption Rate
  It has a smaller user base compared to other application servers like Apache Tomcat or WildFly, potentially leading to less community support.
• Limited Commercial Support
  While there is commercial support available, it is limited compared to other leading application servers, which might deter enterprise users seeking robust support options.
• Resource Intensive
  GlassFish can be resource-intensive, requiring significant memory and processing power, which may not be ideal for smaller deployments.

Possible disadvantages of Payara Server

• Learning Curve
  For new users, there might be a steep learning curve in understanding Jakarta EE specifications and how Payara Server implements these functionalities.
• Performance Overhead
  It can have higher overhead compared to more lightweight, specialized solutions, especially in cases where full Jakarta EE stack is not required.
• Limited Niche Community
  While it is actively developed and supported, the community is smaller compared to other enterprise servers like WildFly or Apache Tomcat, potentially leading to fewer resources and community-driven extensions.
• Version Compatibility
  Some users may face challenges with compatibility when migrating from other application servers, requiring code adjustments to comply with Payara Server's configurations.
• High Support Costs
  While there's a free open-source version, the costs for commercial support can be high, which might be a consideration for smaller businesses.
