DCAE MOD under assessment for EOL with London release
DCAE MOD was introduced in Frankfurt release to address following requirements:
...

Green color → Target level ( details see Platform Maturity below)
Performance: Level 1
Stability: Level 2
Resiliency: Level 2
Security: Level 1+
Scalability: Level 1
Manageability: Level 1+
Usability: Level 1+
...
As DCAE transformation is underway, two different deployment options will be available. The MVP of DCAE will vary based on deployment choice and will include the necessary subcomponents supporting the primary objectives: meeting platform maturity goals and supporting the use cases.
Helm Deployment (dcaegen2-services)
VESCollector
  TCA-gen2
PRH
HV_VES
DCAE-MOD deployment is optional and will include following component (controlled via helm chart configuration under OOM)
Genprocessor
MOD/NiFI UI
Distributorapi
Runtimeapi
Onboardingapi
Note: DCAE-MOD is possible candidate for retirement with London release.

Area	Actual Level	Targeted Level for current Release	Comments
Performance	1	1	Level 0: no performance testing done Level 1: baseline performance criteria identified and measured (such as response time, transaction/message rate, latency, footprint, etc. to be defined on per component) Level 2: performance improvement plan created Level 3: performance improvement plan implemented for 1 release (improvement measured for equivalent functionality & equivalent hardware)
Stability	2	2	Level 0: none beyond release requirements Level 1: 72 hour component-level soak test (random test transactions with 80% code coverage; steady load) Level 2: 72 hour platform-level soak test (random test transactions with 80% code coverage; steady load) Level 3: track record over 6 months of reduced defect rate
Resiliency	2	2	0 – none 1 – manual failure and recovery (< 30 minutes) 2 – automated detection and recovery (single site) 3 – automated detection and recovery (geo redundancy)
Security	1	1+	Level 0: None Level 1: CII Passing badge Including no critical and high known vulnerabilities > 60 days old Level 2: CII Silver badge, plus: All internal/external system communications shall be able to be encrypted. All internal/external service calls shall have common role-based access control and authorization using CADI framework. Level 3: CII Gold badge

List the API this project is expecting from other projects. Prior to Release Planning review, Team Leads must agreed on the date by which the API will be fully defined. The API Delivery date must not be later than the release API Freeze date.

Prior to the delivery date, it is a good practice to organize an API review with the API consumers.

Testing and Integration Plans
- - Unit Test addition will be enforced part of new code submission; all components are required to maintain 55% codecoverage at the minumum.
    https://sonarcloud.io/organizations/onap/projects?search=dcaegen2
  - Functional test plan
    DCAE R12 London Testplan
  - CSIT tests will continue to be supported for existing components and new components
    DCAE has number of CSIT - https://jenkins.onap.org/view/CSIT/; these will be continued to be validated during course of development for this release.
  - Pairwise testing will be done in the WindRiver Dev lab; below wiki page captures the test planned
    DCAE R12 London Pairwise Test
  - DCAE also has number of Smoke test (Example - https://logs.onap.org/onap-integration/daily/onap_daily_pod4_master/01-18-2021_08-01/) enabled for several components/flows; these test are validated part of gating for new container releases

Gaps

This section is used to document a limitation on a functionality or platform support. We are currently aware of this limitation and it will be delivered in a future Release. List identified release gaps (if any), and its impact.

...

Risk identified

Mitigation Plan

Contingency Plan

Due to upstream dependency on NIFI project, some of MOD (NiFI) components (designtool/gen-processor/nifi-registry) will remain in java 8

Request exception for SECCOM.

Assess migration to use new MOD2 standalone components for onboarding (based on community resource/support)

MOD retirement under assessment
