This section covers solutions and use case scenarios to modernize the CSP cloud infrastructure environment with Telco Cloud Infrastructure OpenStack Edition. Private Data Center NFV TransformationTransform the cloud infrastructure in the CSP private data centers with the open-source OpenStack IaaS layer together with the VMware core virtualization technologies. Design ObjectivesThe private data center can be transformed by using a common shared pool of resources with multitenant compute, storage, and network isolation. Use the NSX-T Data Center advanced networking and acceleration capabilities for control and data plane workloads. Workload AccelerationThis version of the Telco Cloud Infrastructure OpenStack Edition 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 NFV transformation on a shared resource infrastructure environment with multitenant consumption models. The design of those tenant environments is outlined in this section. Distributed CloudsThe NFV transformations in the private cloud span distributed topologies. User plane functions such as EPC gateways, and IMS media moves closer to the edge clouds for lower latency and compute proximity. Control plane functions can be centralized. Workload On-BoardingThe VNF onboarding process is typically a collaborative effort between the VNF vendor and the CSP. A prescriptive set of steps must be followed to package and deploy a VNF. The VMware Ready for NFV program is a good vehicle to pre-certify the VNFs and the onboarding compliance with the Telco Cloud Infrastructure OpenStack Edition platform to ensure smooth deployment in the CSP's environment. Availability and Disaster RecoveryBusiness continuity is supported by the Telco Cloud Infrastructure OpenStack Edition platform across its management, control, and data plane components. This section discusses the available designs and recovery considerations.
