The five architectural pillars on which vCloud NFV OpenStack Edition stands are driven by VMware customer requirements and the individual component capabilities.

Carrier Grade
Variety of VMware customers from industries such as the large enterprise, health care, and finance are using the product components from the vCloud NFV OpenStack Edition platform. Carrier grade capabilities are continuously added to the platform to address the requirements of VMware CSP customers. With this release, improvements in high availability and performance are fundamental to the vCloud NFV design.
Modularity
vCloud NFV organizes distinct functions into pods. A pod is a grouping of compute, network, and storage that work together to deliver a function that the solution requires. Each pod has its own characteristics in terms of role, performance, and scale. This architectural best practice enables efficient resource management, creates a clear demarcation between resource providers and resource consumers, establishes security boundaries, and allows for the design of different levels of availability based on cluster workloads.
Service Life Cycle
The service life cycle design principle focuses on ease, and the speed at which the NFV platform consumes the VNFs, maintained over their life time, and deployed when needed. The VIM facilitates this approach and enables the CSP to perform common tasks to benefit from virtualizing network functions.
Tenant Based Architecture
The NFVI is shared between multiple entities, referred to as tenants of the NFVI. A fundamental aspect of the design is ensuring that multiple tenants remain logically isolated from each other, although the physical and virtual layers they use may be shared.
Integrated Operations Management
The multilayer, multi-vendor nature of the NFV environment can increase the operational management complexity. To resolve this complexity, vCloud NFV OpenStack Edition is integrated with a robust operational management system that monitors and analyzes components that are involved in the NFV environment. When the physical servers and switches include monitoring adaptors for the VMware operational management components, the entire system, including the virtualization layer and the VNF themselves, can be automatically discovered, monitored, and analyzed.
