This section describes a set of solutions and use case scenarios to modernize the CSP cloud infrastructure environment with Telco Cloud Infrastructure. Private Data Center TransformationTransform the cloud infrastructure in the CSP private data centers with the VMware Cloud Director IaaS layer together with the VMware core virtualization technologies. Workload AccelerationThe Telco Cloud Infrastructure platform supports accelerated data plane. Both control and user plane workloads can take advantage of this capability and achieve high throughput, reduced latency, and scale in performance. Multi-TenancyThe CSP can facilitate the transformation on a shared resource infrastructure environment with multitenant consumption models. The design of those tenant environments is outlined in this section. Distributed CloudsThe transformation in the private cloud spans the distributed topologies. For low latency and compute proximity, user plane functions such as Evolved Packet Core (EPC) gateways and IMS media move closer to the edge clouds. Control plane functions can be still centralized. Workload On-BoardingThe VNF onboarding process is typically a collaborative effort between the VNF vendor and the CSP. A prescriptive set of steps needs to be followed to onboard and deploy a VNF. The VMware Ready for NFV program is a good vehicle to onboard and certify the VNFs on the Telco Cloud Infrastructure platform to ensure smooth deployment in the CSP's environment. Availability and Disaster RecoveryBusiness continuity is supported by the Telco Cloud Infrastructure platform across its management, control, and data plane components. This section discusses the available designs and recovery considerations. NSX Data Center for vSphere Coexistence with NSX-T Data CenterAs NSX evolves from NSX Data Center for vSphere to its successor NSX-T Data Center, CSPs can deploy the Telco Cloud Infrastructure platform with two software-defined networking stacks simultaneously. CSPs can deploy NSX Data Center for vSphere along with NSX-T Data Center as part of Telco Cloud Infrastructure or as a complement to an existing VMware vCloud® NFV™ deployment. Telco Edge for Telco Cloud InfrastructureTelecommunication operators require a dis-aggregated and distributed virtual infrastructure that allows them to selectively place workloads closer to the subscriber, especially with the advent of 5G networks. These distributed mini or micro data centers are broadly termed Telco Edge sites. The geography of a country coupled with its population density can lead a typical Telco operator to deploy thousands of these Edge sites to cater to multiple use cases.
