This document discusses distributed continuous integration (DCI), which aims to change how partners interact with Red Hat OpenStack. DCI allows partners and customers to test the latest Red Hat OpenStack builds in their own environments. It shortens certification testing time and simplifies upgrades by testing incremental changes. DCI provides automated feedback to Red Hat to improve products based on partner and customer use cases.

● 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.

OBJECTIVES:
DCI aims to change the way Partners interact with Red Hat. The main objectives are
to:
● Improve the influence of key use cases in the development of the product by
enabling a mechanism to provide automated and actionable feedback on any
given release.
● Continuous certification.
● A path for fast adoption of new releases.
● Cross-product continuous integration.
