5. 1. The CSP provides infrastructure only. So, it is end customer‟s responsibility to deploy and
manage applications and other services like WAN Optimization
2. The CSP provides infrastructure and services like WAN Optimization. In this case, the end
customer will have to choose the WAN Optimization vendor as provided by the CSP
3. The CSP provides infrastructure and WAN Optimization service. However, end customer wants
to use their own WAN Optimization. For example, customer may have their „enterprise‟ license
from the WAN Op vendor. So, there is no need for them to pay separately to use CSP provided
WAN Optimization VM/service.
