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.
Since Jakarta release, DCAE Platform component centered around Cloudify has been deprecated; all Microservice orchestration and lifecycle management are handled through Helm/Kubernetes.
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 architecture of DCAE targets flexible, micros-service oriented, model based component design and deployment. DCAE offers support for multi-site collection and analytics operations which are essential for large ONAP deployments.
Following are the planned scope for Kohn release (more info on the commitment and supporting companies documented under DCAE R11 Kohn M2 Release Planning)
Following new service will be delivered for Kohn
Refer DCAE R11 Kohn M2 Release Planning#Scope for more details
DCAE MOD under assessment for EOL with London release
DCAE MOD was introduced in Frankfurt release to address following requirements:
With DCAE platform transformation feature, requirement #1 and #2 are less critical as the onboarding/deployment are easily managed through Helm-Charts and catalog supported through Chartmuseum (or any other registry). Also with Acumos project archived under LF (end of 2021), DCAE team will be assessing the need for continuation/support of DCAE MOD going forward.
Note: Certain MOD components are on java8 due to upstream dependency with Apache/Nifi project on java8 and have SECCOM exception currently.

DCAE Platform
DCAE Service Components
Deprecation Notice: Following Platform API's will be deprecated post Kohn release if no new usecase/driver is identified for ONAP releases. For the interim time, MOD component will be retained in deployment using Jakarta version (no new enhancement/updates are planned)
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.
As DCAE collectors are extensively used in all ONAP usecase, performace testing has been done on below collectors

PM-Mapper performance baseline
Datafile Collector (DFC) performance baseline results
