Today’s software production is increasingly distributed. Gone are the days of one-company, one-site projects; most industry developments involve teams split over locations, countries, and cultures. Software tools have not kept up; they provide too little support for this new reality of software development.
The idea of the CloudStudio project was born out of our experience with distributed software development, both in industry and at ETH. Such development involves many teams working on a common software project, but in different locations (often separated by several time zones) and with radically different backgrounds.
We found that today’s understanding of distributed software development is insufficient and traditional tools are insufficient for effective collaboration:
- A need for better scientific understanding. Today’s scientific understanding of the challenges of distributed software development is limited. In order to develop applicable solutions for today’s development problems we need a better understanding of the critical factors involved in distributed software development.
- Communication is a key challenge. Existing tools such as Skype, WebEx, Google Docs are useful but are not meant for software development.
- Configuration management, the key day-to-day practical issue, is a major hurdle. While configuration management is essential in any team effort, the tools, based on 20-year-old concepts, are heavy to use (requiring constant «update» and «commit» operations) and poorly adapted to modern distributed projects.
We have developed an experimental distributed software development environment, CloudStudio, which addresses the special needs of modern development. In particular:
- CloudStudio gives each developer the appearance of having her own copy of the project, but individual changes are constantly synchronized between all team members. The system automatically reconciles changes, requiring user confirmation only in rare cases. There is no need for traditional configuration management (check-out, check-in): it is all done in the background as a result of editing actions.
- Debugging, a development activity used to find programming mistakes, sometimes need to be done collaboratively by multiple developers. CloudStudio features a novel real-time collaborative debugger whose efficiency and effectiveness has been demonstrated in user studies.
- As part of the CloudStudio project, we have performed empirical studies on how communication is affected by geographical distribution of teams, how development processes influence the success of distributed software development project and how software evolves over long periods of time. Findings were published in peer-reviewed conferences and journals.
What is special about the project?
CloudStudio integrates practical yet revolutionary ideas of software development. The result is a working «proof of concept» that sparked vast interest in academia and industry to investigate more advanced tools for collaborative distributed software development.
