MSB:
1 High Level Component Definition and Architectural Relationships
The Microservice Bus function provides service registration, discovery and communication services for microservices as well as a gateway for internal & External communication for the services:
Register communication services
Discover communication services
Manage communication between microservices
OOM connects to MSB to register and update service information when it instantiates service endpoints.
Question: How do we differentiate between when to use MSB vs When to use DMaaP?
2. API definitions
MSB provides the following interfaces:
| Interface Name | Interface Definition | Interface Capabilities |
|---|---|---|
| MSBE-1 | Registration and Discovery interface | The registration and discovery interface provides the following capabilities:
|
| MSBE-2 | Service Request Interfaces | Provides the capability to deliver and recieve a service request and subsequent communication. |
| MSBE-3 | MSB Admin Interface | Provides the ability to administer policy and routing for the service requests. |
Note: xxxI interface is a Component internal interface. xxxxE interface is a component external interface
The current API documents can be found at:
MSB consumes the following Interfaces:
| Interface Name | Purpose Reason For Use |
|---|---|
| N/A | N/A |

4. known system limitations
MSB API gateway has been tested in this scenario:
- Client(wrk) --> MSB API gateway --> Test service(Tomcat)
- Test machine (client, msb and test service): 8 cpu Core, 8G memory
- Network 10000M
The test result is 50000 request per second.
5. Used Models
Clamp uses the following models:
- Service model (received from SDC)
- VNF model (received from SDC)
- Policy Model.
6. System Deployment Architecture
This needs to be updated, what should be here?
MSB consists of 5 containers:
- CLAMP container
- MariaDB container
- Kibana container
- E_Search container
- LogStash container
7. New Capabilities in this Release
This release, MSB adds the following Capabilities:
