Distributed Management application Requirements / Considerations
Definitions
Day0 configuration: Configuration that is applied at the time of VNF instantiations (Example: Ether config-drive, config-init or config-map)
Day 2 configuration: on-going configuration after Day-0 configurations
(in VNFs, Day 1 configuration is treated as Day 2 configuration in the following table)
Management application: Can be ONAP component or equivalent component from third parties
Requirement Item | Priority | Added by | Modified by and modification | Mapping to requirements from DCAE team |
---|---|---|---|---|
Ability to onboard management applications, that are to be deployed in cloud-regions, in ONAP-Central. Shall not have any expectations that all management applications are onboarded as a single bundle. | high | Allow new MS/applications/components to be onboarded independently | ||
Ability to compose multiple management applications to be part of one management bundle and defining the dependency graph of applications belonging to a bundle | high | Allow Service assurance flow composition and deployment of individual or group of component | ||
Ability to deploy ONAP management applications in selected cloud regions that are owned by ONAP operator | high | Srinivasa Addepalli | Allow Service assurance flow composition and deployment of individual or group of component | |
Ability to deploy management applications that are ephemeral (example: Analytics applications) | high | Allow Service assurance flow composition and deployment of individual or group of component | ||
Ability to deploy ONAP management applications in selected cloud regions that are not owned by ONAP operator, but has business relationship (Examples: Public Clouds or Edge Clouds owned by some other organization) | medium | Srinivasa Addepalli | ||
Support for deploying management applications independent of each other when there are no dependencies (no expectation that all management applications are brought up together). | high | Allow Service assurance flow composition and deployment of individual or group of component | ||
Ability to deploy few management applications based on VNF instantiations and bring down when VNF is terminated | high | Dynamic deployment of MS based on xNF instantiation | ||
Ability to apply common configuration (Day0 configuration) of ONAP components management applications at the time of deployment | high | |||
Support for various Day0 configuration profiles | high | |||
Support for Day 2 configuration of single or multiple instances of ONAP components management applications in various cloud regions | high | Srinivasa Addepalli | ||
Support for management applications depending on other management applications - Support for configuration (Day2 configuration) of provider services when the consuming service is being instantiated and removal of the configuration on provider services when consuming service is terminated (Example: When analytics applications are brought up, analytics/collection framework need to be updated with additional configuration such as DB table, Kafka topic etc..) | high | Srinivasa Addepalli | Dynamic topics provisioning and role assignment for MS | |
Support for Day 2 configuration (add/delete) of appropriate management applications upon VNF instantiation/termination (Example: configuration of analytics & collection services when VNFs are brought up and removing the added configuration upon VNF termination) | high | Srinivasa Addepalli | Dynamic reconfiguration of MS based on xNF instantiations | |
Secure connectivity between central ONAP and ONAP management applications in cloud regions | high | |||
Support for various connectivity protocols (Kafka, HTTP 1.1, 2.0, GRPC etc...) between ONAP-Central and ONAP management components in cloud regions | high | |||
Monitoring and visualization of ONAP components management applications of cloud-regions along with ONAP components at the ONAP-Central | high | Complete view of MS and relation maintained at single/multisite K8S scenarios Healthcheck of all deployment component to be available for CLAMP/external system | ||
Scale-out of ONAP management application components at the cloud-regions & traffic (transaction) distribution | high | |||
Ability to upgrade ONAP management application components without loss of functionality | low | |||
High availability of ONAP component management applications in the cloud regions | high | |||
Support for third party management applications that provide similar functionality as ONAP management applications (Modularity) | high | |||
Support management applications as containers | high | @Srinivasa Addepalli | ||
Support management applications as VMs | low |
