Technical debt – the cost of an open source fork; an interview with Allison Randal

In this six minute interview Allison discusses technical debt.

When software is developed in open source, collaborators develop code in a central repository. If an individual or organization downloads the code, makes changes to the code and does not submit those changes to the central repository, they now have to maintain what is known as a “fork”. The longer the organization maintains their own version of the software code (red line in graphic below), the more expensive it becomes to move the code back into the upstream repository.

If an organization’s code is not part of the upstream repository they do not benefit from the collaboration, expertise and knowledge that takes place in the central code repository.

Introducing OpenCloudNow

Welcome to OpenCloudNow.

This series of blogs, podcasts and videos will cover how to build and use a cloud using open source software and why open source is a better alternative than closed source or proprietary software.

The views expressed in these blogs, and those of my guests are, our own.

The blogs will follow this outline, though this page will be updated with any changes.

Business value topics

  1. Why upstream matters.
  2. Software licenses, legal view points: open source vs closed source.
  3. Software purchase models: subscription vs license+support.
  4. Suites vs bundles vs products: how is software packaged.
  5. Security and compliance.
  6. Lock-in: What is lock-in and how to avoid it.

Technical topics

  1. Automation.
  2. Operating systems.
  3. Hypervisors.
  4. Compute.
  5. Networking.
  6. Storage.
  7. Cloud Management.
  8. Containers.

Looking forward to the discussion
