A recent research report on the current state of the application server market found that 36% of Oracle WebLogic and IBM WebSphere users are likely to move to a different primary production application server within two years. According to the study, a joint effort by MuleSoft and Computerworld, IT and business leaders cited vendor lock-in, high cost, and difficulty of management as the top three reasons they are dissatisfied.
The findings indicated that Apache Tomcat (the most widely deployed open source application server, according to the study) eliminates some of the primary issues respondents have with the legacy JavaEE app servers. However, IT administrators, architects, and developers overwhelmingly agreed on important areas of improvement for Tomcat, including:
- Server group administration and control (94%)
- Simplified integration with data sources (94%)
- Performance monitoring and diagnostics (82%)
- Application configuration automation (78%)
- Better integration with developer tools such as Eclipse or Maven (74%)
- Application deployment and release management (73%)
Respondents cited the current state of these features as barriers to deploying Tomcat in production. In fact, only 31% of Tomcat users claimed to have deployed it as their primary production application server.
