挑战

NetworkedAssets, a software house specializing in telecoms, faced challenges in streamlining their development processes to enhance efficiency and productivity. The team, working as a distributed agile unit, used the scrum template with two-week iterations. Continuous Integration was crucial, and they used Hudson for building applications and running unit tests after each commit. Despite these measures, the application redeploy time was significant, typically around 4-5 minutes, 2-3 times an hour, which added up and impacted productivity. The application, developed in Eclipse and built with Maven, included multiple frameworks like Spring, Hibernate, and Apache Camel, and was deployed on Apache Tomcat. The team needed a solution to reduce the redeploy time and improve their development velocity.

关于客户

NetworkedAssets is a seven-year-old company based in Berlin, with 26 employees working across Germany, Austria, Switzerland, and Poland. The company focuses on integrating processes and data for telecom companies with large IP networks, serving over a million users. NetworkedAssets is also an Expert Partner of Atlassian. The company develops applications primarily on Java and the JVM, using Unix and Linux platforms. Their solutions include network management and monitoring, provisioning network resources, distributing resources over access points, automating network management tasks, and on-demand IPTV solutions. The development team consists of 22 developers who work as a distributed agile team, emphasizing continuous integration and code quality monitoring.

解决方案

NetworkedAssets decided to integrate JRebel into their development process to address the issue of significant redeploy times. JRebel allowed developers to change code or framework resources and instantly view and test their changes without delays. The application, which included frameworks like Spring, Hibernate, and Apache Camel, was developed in Eclipse and built with Maven, where JRebel integrated directly with the build. The app, consisting of four modules and many libraries, was deployed on Apache Tomcat. By using JRebel, the team could significantly reduce the redeploy time, enhancing their development productivity. The team ran metrics to compare the velocity across iterations with and without JRebel. They performed eight sprints without JRebel and six sprints with it. The results showed a significant improvement in team velocity when using JRebel.
