7 years of open source: Cloud Foundry, Diffblue & Quest

As the Computer Weekly Open Source Insider blog approaches it’s 1000 post since first starting in June 2010, we feature a number of comments from movers (and hopefully shakers) in this space.

Looking back seven years, it was almost slightly hopeful to dedicate a whole column to open technologies, platforms, tools, software languages and wider open design principles.

Today, things are different, as we know… and even Microsoft ‘hearts’ Linux, right?

Let’s hear from the Cloud Foundry Foundation, coding tools startup DiffBlue and software management tools company Quest.

Cloud Foundry

Abby Kearns is executive director of the Cloud Foundry Foundation.

Looking at the macro-level progression of technologies across the seven year period in question, Kearns offers some insight into where open source ‘weight’ has been felt over what is most of a decade.

“In mid-2010, cloud computing was beginning to take hold. Amazon Web Services (AWS) was synonymous with the term. While AWS still holds a majority share, the companies growing and building the cloud are doing so on the back of open source technologies like Cloud Foundry, Kubernetes and the Open Container Initiative,” said Kearns. “To put it another way: open source had won the datacentre by 2010. In 2017, it has won the next generation of enterprise technology: the cloud.”


Daniel Kroening is professor of Computer Science at Oxford University and founder of Diffblue, a automated code quality testing and management tool.

“Throughout these past seven years, open source has been thoroughly embraced by companies – nine out of ten UK enterprises currently use open source software to reduce IT project costs by over £30,000, with 78% of companies using it. The community has earned a lot of trust. However, software developers often erroneously assume that open source components are reliable, patched and up to date but more than 50% of the Global 500 use vulnerable open source components,” said Kroening.

Kroening and team say that their goal with Diffblue is to automate ‘all traditional’ coding tasks: bug fixing, test writing, finding and fixing exploits, refactoring code, translating from one language to another and creating original code to fit specifications.


John Pocknell is senior product manager at Quest.

Pocknell says that since the turn of the decade, the open source movement has played a critical role in the evolution of technology and the way products or services are built.

“Innovation thrives on the contributions from the developer community and despite resistance in the early days, it’s given rise to open development platforms like GitHub and Docker, but also new toolsets for development, management, and migration of databases. Now companies who were built in the age of hardware can still thrive in the open, digital-first era, thanks to open source,” said Pocknell.
