1. Project Overview
DCAE project provides intelligence for ONAP to support automation (via open-loop and CL) by performing network data collections, analytics & correlation and trigger actionable rootcause events.
DCAE components are classified between platform and service components. DCAE Platform refers to the set of controller components which manages deployment and LCM of DCAE service components. The DCAE services components includes all the microservices - collectors, analytics and event processor which supports active data-flows and processing as required by ONAP usecases.
The platform includes components collectively fulfilling the role of Data Collection, Analytics, and Events generation for ONAP. The architecture of DCAE targets flexible, pluggable, micros-service oriented, model based component design and deployment and service composition. DCAE also offers support for multi-site collection and analytics operations which are essential for large ONAP deployments. DCAE components generally fall into two categories: DCAE Platform Components and DCAE Services Components.DCAE Platform refers the set of controller components which manages the deployment and LCM of the DCAE service components which include all the collectors, analytics and event processor MS.

Relies on k8s for loadbalancing and scaling. DCAE platform handles the control flow and do not carry the data/event; DCAE service components can be scaled and support state management through external DB and/or K8S state management.
Cloudify is 3rd party product; multi-site feature on community version will be available later in 20192020; will be incorporated for E G release.
