Ice Rule Engine Architecture Design

In-depth understanding of Ice rule engine's technical architecture and core components

Ice Rule Engine Overall Architecture

Ice rule engine adopts Client-Server architecture design, achieving separation of rule configuration and business execution, supporting hot rule updates and dynamic orchestration.

Core Components

IceServer - Rule Management Platform

  • Positioning: Visual configuration management center for Ice rule engine
  • Core Capabilities:
    • Provides web visual rule configuration interface
    • Stores and manages all rule configuration data
    • Supports rule version management and history rollback
    • Real-time push of rule configuration changes to Client
    • Multi-application (App) isolation management

IceCore - Rule Execution Engine

  • Positioning: Business execution core of Ice rule engine
  • Core Capabilities:
    • Pulls and caches rule configurations from Server to memory
    • Monitors rule configuration changes and updates in real-time
    • Provides high-performance rule execution interface
    • Supports multiple node types and orchestration modes
    • Pure in-memory computation with millisecond response

BaseNode: The base class of all ice nodes, providing common node operations, such as node valid time, etc.

BaseRelation: The base class of all relation nodes, used for business flow control.

BaseLeaf: The base class of all leaf nodes, the leaf nodes are the nodes that actually execute the business.
