Evolution to Hybrid/Multi-Cloud
Public Cloud (IaaS, SaaS)
• Flexibility
• Economies of scale
• Peripheral apps
Managed Private Cloud
(IT Outsourcing)
• Traditional outsourcing model
• Easy to migrate
Self-Managed
Hybrid/Multi-Cloud
• Elasticity and cost
advantages of public cloud
• But: avoid lock-in
• Granular in-house control
Managed Multi-Cloud
as a Service
• Value-added services
• Outsourcing advantages:
Lower fixed costs and
economies of scale
2013 2019
Private Cloud (Self-Managed)
• Leveraging cloud architecture
• But in-house control
• Mission critical appp
• Lower cost for large ENTs

Cloudstack + OPENCONTRAIL
Improved Cloud Time-to-Value
 Make existing cloud deployments
more network capable and
scalable
 Extends existing network
investments to better support
cloud
 Accelerates business value by
bridging the gaps between
