● OSP is in sync with OpenStack upstream and follow the cadence.
● OpenStack comes with a lot of drivers
● Red Hat works with a large number of partners
● Partners want to prepare their solution before OSP GA
● Customers may also have complex topology
● Testing testing time
A Bit of context

3. 3
● Allows Partners and Customers to work on the latest Red Hat OpenStack builds
available, as soon as possible, in their own environment.
● Shortens the time and effort for RHOSP Certification since it can run the certification
test suite on every change.
● Simplifies the upgrade progress by testing incremental changes.
● Provides automated feedback to Red Hat with helpful logs.
● Focus debugging efforts on the subset of the code that has changed.
● Include RHOSP tests as well as Partner's and customer's specific tests.
● Gives customers the ability to continue to test RHOSP beyond GA.
WHY DISTRIBUTED CONTINUOUS
INTEGRATION?
DCI aims to change the way partners interact with Red Hat OpenStack.
