1. High Level Component Definition and Architectural Relationships

2. Template Component API definitions

Template Component provides the following interfaces:

Interface Name	Interface Definition	Interface Capabilities	Version	Status	Consumed Models	API Spec (Swagger)
HOLMESE-1	This is a set of rule management interfaces, which is mainly intended for the CRUD actions of the rules of Holmes.	Allows applications to create, update, delete, and query the rule entities.	1.0.0	production	Defined by Holmes	swagger.json
HOLMESE-2	Health check.	Allows other applications to perform healthcheck on Holmes.	1.0.0	production	-	swagger.json

Template Component consumes the following Interfaces:

Interface Name	Purpose Reason For Use	Version(s)	API Spec (Swagger)
POE-4	To send the closed control loop events to policy to trigger downstream actions.	-	Closed Loop Event Data Structure
Service Binding Service API	To retrieve default configurations (e.g. default rules and DMaaP configurations, etc.)	2.5.3	swagger.json
DMaaP-2	To retrieve VES events from DMaaP.	4.0.0	swagger.json
DMaaP-3	To send closed control loop events to DMaaP.	4.0.0	swagger.json
AAIE-1	To query resource information from A&AI.	v19	aai_swagger_v19.html aai_swagger_v19.yaml

A more detailed figure and description of the component.

Performance limitation: if it comes to high-performance scenarios, and A&AI happened to be needed for alarm analysis and correlation, there could be a performance bottleneck as all A&AI API calls are based on HTTP requests, which is considerably time-consuming.
