DRAFT PROPOSAL FOR COMMENTS
The content of this template is expected to be fill out for M1 Release Planning Milestone.
...
Microservices Bus provide key infrastructure functionalities to support Microservice Architecture ONAP microservice architecture including service registration/discovery, service gateway, service load balancer and service governance. It's a pluggable architecture so it can plugin service provider options like AAF to provide Authentication & Authorization for APIs. Microservices Platform also provides a service portal and service requests logging, tracing and monitoring mechanism, etc.
...
Service Router(Internal API Gateway)
Stretch Goal: Integrate with OOM so OOM can register service endpoints to MSB after deploying and starting an ONAP component/service.
Stretch Goal: Integrate with AAF so MSB API Gateway can work with AAF to provide centralized authentication and authorization for ONAP platform.
Stretch Goal: Integrate with for discovery of Dmaap topics in addition to RESTful API’s.
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.

Indicate at a high level the longer term roadmap. This is to put things into the big perspective.
Provide a high performance, high availability microservice infrastructure layer for ONAP platform, including service registration&discovery, service API gateway and service governance.
Release Deliverables
Indicate the outcome (Executable, Source Code, Library, API description, Tool, Documentation, Release Note...) of this release.
Deliverable Name | Deliverable Description | To fill out | To fill out|

Sub-Components
List all sub-components part of this release.
Activities related to sub-component must be in sync with the overall release.
Sub-components are repositories are consolidate in a single centralized place. Edit the Release Components name for your project in the centralized page.
ONAP Dependencies
- Integration: work with Integration project to integrate MSB with other ONAP components
- OOM: work with OOM team to register services to MSB after ONAP components are deployed and started by OOM
- AAF:work with AAF team to provide centralized authentication an authorization fro ONAP components. (It's just a proposed solution which is under discussion now)
Architecture
High level architecture diagram
...
Anyone reading this section should have a good understanding of all the interacting modules.
Sequence diagram
Service Registration & Discovery
User login flow with Auth service provider
(Note: API token may be used for the external systems such as OSS/BSS, however, the generation of API token is not considered to be relevant to MSB(External API Gateway))
External service request flow
(Assumption: the external system(OSS/BSS) or user agent(Browser) already get authenticated and allocated a token, it can be either a user token for ONAP user or an API token for OSS/BSS)
Internal service request flow
Option 1: Service consumer and service provider communicate with each other via Internal API Gateway
Option 2: Service consumer uses MSB client SDK to communicate with service provider directly
API Incoming Dependencies
...
Name | Description | Version |
---|---|---|
Consul | Consul is a distributed, highly-available, and multi-datacenter aware tool for service discovery, configuration, and orchestration. | 0.8.4 |
OpenResty | OpenResty® is a full-fledged web platform that integrates the standard Nginx core, LuaJIT, many carefully written Lua libraries, lots of high quality 3rd-party Nginx modules, and most of their external dependencies. It is designed to help developers easily build scalable web applications, web services, and dynamic web gateways. | 1.11.2.3 |
Redis | Redis is an in-memory data structure store, used as a database, cache and message broker. | 3.2.8 |
In case there are specific dependencies (Centos 7 vs Ubuntu 16. Etc.) list them as well.
...
Describe the plan to integrate and test the release deliverables within the overall ONAP system.
Confirm that resources have been allocated to perform such activities.
- Unit test: the goal is 50% coverage for Amsterdam Release.
- Functional test: Leverage the robot framework infrastructure to provide functional test.
- Integration test: Support integration team to provide the end to end integration test.
- All the above should be automation tests run on the LF Jenkins Infrastructure.
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.

MSB needs to work with OOM to register services to MSB service registry, given that OOM is a newly created project, there may be a risk that the cooperation job between MSB and OOM can't be done in the release 1. | Work with OOM team closely and try to put this job in the priority task list of OOM team. | MSB provide Restful APIs and UI Portal so ONAP services can be manually registered.To fill out |
