LineSider's white paper on Network Services Virtualization elaborates on the challenges by bringing out the limitations of point2 products of the following types:
- Configuration Management and Automation Engines
- Inventory and Capacity Management
- Network Alarm and Correlation Management
What is the moral of the story? While it is important to create point technologies for the cloud, it is also important to think about their manageability in an 'end-to-end' scenario: The cloud subscriber is one of the ends, and the cloud provider is the other end, with all the devices in between — physical or virtual — associated with the cloud service in a persistent, auditable, manner.
