Who Should Assure


Private Cloud Performance? THE RESPONSIBILITY IS ON YOU, SO HERE’S A “HOW-TO”


18 BY TOM NOLLE Accommodate New


Traffic Patterns The starting point for private cloud performance


assurance is the question of how much traffic patterns and volumes are likely to change as a result of the private cloud technology used to augment or displace traditional data center hosting of applications. If we assume that the private cloud generates the same traffic as the older data center configuration, then no special issues would arise. In most cases, though, there will be some differences in traffic associated with private cloud deployment, and these differences will have to be accommodated to stabilize application QoE through the transition.

Connectivity Requirements The primary question for user-to-cloud performance


assurance is whether the private cloud introduces new data center connectivity requirements. No matter how many data centers might be used in a private cloud,


Public cloud services are most likely to be accessed over the Internet where users have little control over their experience. For most private cloud computing environments, the cloud will inherit the WAN technology already used to connect users with conventional data centers. This scenario will give enterprises more control and more responsibility for network performance assurance.
