A Carrier grade PaaS aims to bring the network and application together. That means that application can easily deployed on multiple sites on different physical location as if it was one big data centre. Unlike regular cloud environment where application need to explicitly handle multi-zone deployments with Carrier PaaS the application workload and availability is handled through policy driven approach. The policy describes the desired application SLA and the Carrier PaaS maps the deployment of the application resources on the cloud node that best fit the latency, load or availability requirements.
