DCAE provides the ability to detect anomalous conditions in the network. Such conditions, might be, for example, fault fault conditions that need healing or capacity conditions that require resource scaling. DCAE gathers performance, usage, and configuration data about the managed environment, such as about virtual network functions and their underlying infrastructure. This data is then distributed to various analytic micro-services, and if anomalies or significant events are detected, the results trigger appropriate actions. In addition, the micro-services might persist the data (or some transformations of the data) in the storage lake. In addition to supporting closed-loop control, DCAE also makes the data and events available for higher-level correlation by business and operations activities, including business support systems (BSS) and operational support systems (OSS).
