PHILADELPHIA, April 02, 2019 (GLOBE NEWSWIRE) -- On the eve of the Cloud Foundry Summit in Philadelphia this week, source{d}, the data platform for your software development life cycle, released the results of its analysis of the Cloud Foundry codebase, revealing a platform with significant breadth and depth with high release velocity.

The analysis leverages source{d} Engine to retrieve and analyze all Cloud Foundry Foundation’s git repositories through SQL queries to get insights into the project codebase history, as well as emerging trends. 

The analysis found:

  • Large number of repositories (853 repositories across three GitHub organizations) revealing the breadth and depth of the platform distributed across myriad small projects and components.
  • High release velocity with an average of 98 project releases per month and three major phases in history: Cloud Foundry core in 2013, Diego container runtime in 2015 and Cloud Foundry deployment in 2018.
  • The number of files over time (just under 400,000 at the beginning of 2019) reveals an exponential growth from 2011 to 2017 which seems to have slowed down in 2018, a sign of maturity and stability.
  • The number of files over time per repository shows the importance of buildpacks, and in particular of the dotnet-core-buildpack repository which highlights the enterprise nature of the application workloads running on the Cloud Foundry platform.
  • The dominant programming language by number of files is by far Ruby with almost 50% of the total, followed by YAML and Go.
  • The top repositories by number of commits are public-buildpacks-ci-robots and relint-ci-pools, two continuous integration repositories which reveals a strong focus on stability. Also included in the top five are BOSH and Stratos, two projects focused on the virtual infrastructure management layer and providing a user interface to the Cloud Foundry Application Runtime, another sign of maturity.

“The source code analysis shows a mature but extraordinarily active, complex project,” said Francesc Campoy, vice president of product and developer relations at source{d}. “The sheer breadth and depth of the project combined with the volume and number of commits paint a picture of extremely robust technology.”

The source{d} analysis included:

  • Release schedule over the past three years (“release velocity”)
  • Number of commits per month
  • Top repositories and number of commits
  • Number of files over time

“The analysis provided by source{d} gives us a fascinating view into one of the world’s largest and most active open source initiatives,” said Chip Childers, CTO, Cloud Foundry Foundation. “To actually pull all this data together in easy-to-understand charts gives us a unique view into both the history and the forward trajectory of our community.”

source{d} Engine provides engineering observability for organizations focused on IT modernization, talent management and the adoption of DevOps best practices at scale.
