CI/CD -OpenSource v.s.Enteprise software development
The light side• Apache Libcloud•Multi-cloud abstraction API for Python• 190k downloads per month• 181 contributors• CII 100% best-practice
The dark side• Enterprise Software
Development team • 90 developers, 4 SCRUM
masters, AGILE (SaFE)• C#.NET 4.5 Business
Application (SaaS)
“Bleep boop boop”- R2D2
• Large number of contributors• Mixed platforms• No verbal communication – varied
language skills• Typically only tested on 1
platform (e.g. Mac OSX, Python 2.7)
• Contributors vary from noobs to gurus
If you want to use the latest stable version, clone trunk
“Great, kid. Don’t get cocky.”

"The dark side of the Force is a pathway to
many abilities some consider to be
unnatural."• Small team 8 developers, 2 QA• Single Platform• Sit next to each other (but don’t talk)• Tested on 1 platform. Deployed on 1
platform• Highly skilled engineers
And yet..
IF you want to use the latest stable version, you wait for the end of the sprint release and the ”definition of done” is completed and QA has passed (and bugs have been fixed).
Tooling shootout?

It’s a trap!

At which point do you realize this change doesn’t work on Safari?
How long does it take to get there?
How many people does it take to spot it?
What is your level of confidence that what comes out of this process is ready for production?
Your mistakes, much time they have cost you
