    Project Overview

    DCAE includes number of

  1. Project Overview

    DCAE platform includes components collectively fulfilling the role of Data Collection, Analytics, and Events generation for ONAP.  The  The architecture of DCAE targets flexible, plug-ableplugable, micros-service oriented, model based component deployment and service composition.  DCAE

    DCAE also support multi-site collection and analytics operations which are essential for large ONAP deployments. DCAE  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.

  6. What are the system limits

    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.
    Cloudify is 3rd party product;

    HA

    multi-site feature on community version will be available later in 2019; will be incorporated for E release.
