Victor Morales
Senior Cloud Engineer

2. Agenda
• Problem statement
• CI/CD principles & practices
• Proposal
• XCI definition and goals
• Main Components
• Workflow
• Features

3. OPNFV - Problem statement
• Late integration – Takes months
for a feature/fix to be available
• Slow feedback – Takes months
to know if a feature/fix works
• Lack of visibility – Not easy to
see the current state
• Too fragmented – Many ways to
do the same thing

4. CI/CD Principles & Practices
• Fail fast, Fix fast
• Always have a working software
• Small and frequent commits
• Reduce the complexity
• Test early and often
• Avoid surprises

5. Proposal

6. Cross Community (XCI)
• It’s an additional OPNFV service that
enables
• Early integration – Works with master
• Faster and tailored feedback
• Reuse – Use of upstream tooling
• Better visibility.
• It aims to bring Continuous Delivery to
OPNFV
• Ensure composed platforms always work
