s. AIC is deployed in dozens of geographically dis- tributed locations, each known as an "AIC site." Within each site, typically located in a city, resides one or more "AIC zones." An AIC zone is the term used to describe the collective set of AIC hard- ware that is managed as a single unit within an AIC site. At the heart of each zone is a collective set of hardware that creates the shared infrastructure platform for the hosting tenant of application virtual machines (VMs), virtual networks, and virtual storage used to provide carrier-grade enterprise and network workloads. The zones may have differ- ent reference models or cloud offerings. For example, datacenter, mobility, and compact. Datacenter-used to automate typical manual data center operations Mobility-similar to a "datacenter," but the support is focused on mobility-related network functions Compact-provides network functions to customers in various market areas and is gener- ally a central office or another location near the customer location AIC zones and reference models are built using a local control plane (LCP) and a distributed control plane (DCP). Each LCP is local to the AIC site. Within the LCP is a set of control serv- ers, VMs, and control applications, including OpenStack (virtual infrastructure manager [VIM]), ONAP (orchestrator), etc., as well as the managed components, such as, servers, switches, and storage. There are no proximity requirements between LCPs and the managed components. For Network Functions Virtualization Infrastructure instance, two compute servers that are in the same rack and connected to the same leaf switches, can be managed by different LCPs. LCPs provide a variety of functions: API management Orchestration Image management Automation Authentication The DCP is a collection of orchestration management servers that control or provide services to multiple AIC locations. Redundant DCPs host centralized components of AIC that are integrated with back office systems to provide information technology (IT) provisioning. Th
