Scope
What is this release trying to address?
MSB(Microservices Bus) provides key infrastructure functionalities to support ONAP Microservice Architecture(OMSA) in Amsterdam and Beijing. In Casablanca, MSB mainly focuses on the integration of Istio service mesh with ONAP to enhance OMSA, while keeping the Istio integration compatible with the existing MSB API Gateway approaches.
Integrate Istio with ONAP to provide a reliable, secure and flexible service communication layer (service discovery/retries/circuit breaker/route rule/policy)
Integrate with CNCF projects jaeger to provide distributed tracing Prometheus and Grafana for metrics collection and display
Add MSB Portal to control plane to provide service catalog, swagger UI of Restful API, service mesh configuration, etc
Use Cases
MSB is an infrastructure layer project to support ONAP microservices architecture, it means that MSB supports every ONAP use case without difference.
Minimum Viable Product
Meet the planned Casablanca platform maturity(S3P) requirements
Integrate Istio with at least one ONAP project to provide service-2-service communication, metrics collection and distributed tracing
Integration MSB with Istio to make service communication via MSB API gateway compatible with service communication via Istio service mesh
Functionalities
List the functionalities that this release is committing to deliver by providing a link to JIRA Epics and Stories. In the JIRA Priority field, specify the priority (either High, Medium, Low). The priority will be used in case de-scoping is required. Don't assign High priority to all functionalities.
Epics
Stories
Longer term roadmap
Run ONAP on top of Istio service mesh.
Leverage Istio to achieve closed-loop operation for ONAP system itself.
Release Deliverables
Indicate the outcome (Executable, Source Code, Library, API description, Tool, Documentation, Release Note...) of this release.
Deliverable Name | Deliverable Description |
|---|---|
API Gateway | Service API gateway which provides client request routing, client request load balancing, transformation, such as https to http, authentication & authorization for service request with plugin of auth service provider,service request logging,service request rate-limiting,service monitoring,request result cache,solve cross-domain issue for web application and other functionalities with the pluggable architecture capability. It can be deployed as external API gateway which is a transparent inter-service communication proxy or internal API gateway which exposes ONAP services to outside world. |
Service Discovery | Provides service registration and discovery for ONAP microservices, which leverage Consul and builds an abstract layer on top of it to make it agnostic to the registration provider and add the needed extension. |
JAVA SDK | Provides a JAVA SDK for rapid microservices development, including service registration, service discovery, request routing, load balancing, retry, etc. |
Swagger SDK | Swagger sdk helps to generate swagger.json and java client sdk during the build time, it also helps to provide the swagger.json at the given URI in the run time. |
MSB Istio Agent | MSB Istio Agent watches MSB services registration changes and automatically creates Istio routing rules which rewrite the requests to MSB internal API gateway to the service destination. |
Mesh Portal | A portal including mesh configuration, service catalog and API management. |
Istio Installation glue scripts | Glue scripts for installation: Istio control plane, Istio data plane and service backends(jaeger, Prometheus, grafana, etc.) |
Documentation | API documentation, tutorial and installation guide |
Sub-Components
List all sub-components part of this release.
Activities related to sub-components must be in sync with the overall release.
Sub-components are repositories and are consolidated in a single centralized place. Edit the Release Components name for your project in the centralized page.

API Incoming Dependencies
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.
Note: MSB project has no incoming dependency.
API Name | API Description | API Definition Date | API Delivery date | API Definition link (i.e.swagger) |
