3. Steps for a successful OpenStack PoC
• Identify a team.
• Define the use case, scope & success criteria.
• Define Reference Architecture
• Define the criteria for comparing distributions
• Identity workloads.
• Define test cases.
• Execute PoC.
• Plan for moving from PoC to Production

• Engineering/DevOps team with experience in
– Network
– Operating Systems
– Storage
– Python programming
• Project Co-ordination, Infrastructure sourcing
• Functional & Performance Testers
• Other Stakeholders
