What is this release trying to address?

MSB(Microservices Bus) provides key infrastructure functionalities to support ONAP Microservice Architecture(OMSA), which includes:

  • Provides RESTFul API for service registration/discovery
  • Provides JAVA SDK for service registration, discovery and inter-services communication
  • Provides a transparent service registration proxy with OOM-Kube2MSB
  • Provides a transparent service communication proxy which handles service discovery, load balancing, routing, failure handling, and visibility by Internal API Gateway(Current implementation) and Mesh sidecar(WIP)
  • Provides an External API Gateway to expose ONAP services to the outside world

Note: The current name MSB(Microservices Bus) can't  well explain the project anymore, we're considering to change to a new name which can better reflect the scope and functionalities of this project.

Use Cases

MSB is an infrastructure project, it means that MSB supports every ONAP use case with no difference.

Minimum Viable Product

  • Meet the planned Beijing platform maturity(S3P) requirements
  • Reach out to help other projects integrate with MSB 


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.

Longer term roadmap

  • Investigate service mesh(Istio) and integrate Istio into OMSA when it's production ready.
  • Work together with Microservice subcommittee and other projects such as OOM/AAF/Logging to achieve OMSA(ONAP Microservice Architecture) to support carrier-grade ONAP platform.

Release Deliverables

Indicate the outcome (Executable, Source Code, Library, API description, Tool, Documentation, Release Note...) of this release.

Deliverable NameDeliverable Description
API GatewayService 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 DiscoveryProvides 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.

Provides a JAVA SDK for rapid microservices development, including service registration, service discovery, request routing, load balancing, retry, etc.

Swagger SDKSwagger 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.
DocumentationAPI documentation, tutorial and installation guide


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.


High level architecture diagram

This diagram shows how MSB project fits in the ONAP Architecture in a very high-level view.

If we take a closer look at ONAP Microservice Architecture, we get this diagram. The yellow blocks are currently in this project.

Please note that this diagram is a functional view of OMSA, which is not mapped to specific projects. So some of the blocks are currently implemented in this project, some of the blocks are implemented in other projects such as OOM and DMaaP, and other blocks may not exist yet, which need to be implemented or integrate with opensource projects to provide these functionalities. MSB will work with the related projects to provide all the OMSA functionalities to support a reliable, resilient and scalable ONAP Microservice Infrastructure.

MSB will provide service mesh as a transparent service communication layer which handles service discovery, load balancing, routing, failure handling, and visibility.

  • 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.
