Best Application Server Software

Application servers provide a framework to build and deploy web applications and offer a variety of services when running such applications. These services include security, transactions, clustering for increased performance, and diagnostic capabilities, among others. These products can also include servers that strictly host web applications. Application servers are used by software developers who are trying to quickly build applications and have them supported by the server environment in which they are deployed. These products allow developers to focus on the application itself and spend less time focusing on outside issues, such as performance or security. Application servers can run in conjunction with relational databases and a variety of web frameworks.

To qualify for inclusion in the Application Server category, a product must:

  • Provide a software framework for building and deploying web applications
  • Offer services to support an application within the hosting server environment
