The carrier cloud is a new class of cloud that brings together the data center and the carrier network for a differentiated, much higher value end-to-end offer. However, to realize the potential, the operation of the carrier cloud needs to be industrialized and automated. This way, the set up times of a networked cloud service can be reduced from weeks to minutes. This is a presentation from the Network Automation Conference, Paris, June 19-21, 2012

6. INTRODUCING CLOUD
ORCHESTRATION AND AUTOMATION
• Orchestration
- Create higher level abstractions/actions
- Predefined workflows for cloud
management tasks
- Predefined error handling
- Internal or external – using APIs
• Automation
- Utilize computations algorithms
ORCHESTRATION
- Trigger automatic actions

14. ORCHESTRATION:
MULTI-OPCO APPLICATION DEPLOYMENT
• Deploy service provider applications
in a multi-opco private cloud
• Meet national constraints
• Flexibly centralize/decentralize apps
• Deployment templates
• Centralized software updates
• National configuration

15. COMPUTE AUTOMATION
COMPUTE RESOURCE PLACEMENT
• Placement of cloud resources in a legacy centralized cloud
- Well understood problem with available commercial solutions CONVENTIONAL
CLOUD
• Resource placement is more complex in networked cloud
- More choices where a requested resource can be placed
- More constraints to take into account CARRIER
CLOUD
- Geographic location preferences
- Cost limits
- Network distance and latency bounds
