That scales beyond your dreams!

11. Technical Forum
We know what’s required
§ Decouple hardware stacks
§ Simplify network designs
§ Abstract HW and topology from
software
§ Automated provisioning,
orchestration

Introducing CloudVision
§ Abstraction of hardware and topology from orchestration
• Ability to flex and adapt northbound and southbound
§ Turnkey core services
• Template driven provisioning/replacement
• Ongoing configuration management and compliance
• Network-wide upgrades and rollbacks
• Inventorymanagement

18. Technical Forum
There is a lot at stake
§ Faster service delivery
