This is an example of an ACL using Go.
Let's say we're modernizing a legacy e-commerce system, where we need to integrate a modern microservice with a legacy monolithic order management system.
graph TD
subgraph "Modern Microservice Architecture"
MS[Modern Order Service]
ACL[Anti-Corruption Layer]
TR[Translation Layer]
AD[Adapter Layer]
end
subgraph "Legacy System"
LS[Legacy Order System]
end
Client[Client Application] -->|Modern REST API| MS
MS -->|Modern Domain Model| ACL
ACL -->|Translation| TR
TR -->|Adaptation| AD
AD -->|Legacy SOAP/XML| LS
style ACL fill:#f9f,stroke:#333,stroke-width:4px
style MS fill:#bbf,stroke:#333,stroke-width:2px
style LS fill:#fbb,stroke:#333,stroke-width:2px
Each layer serves a specific purpose:
ModernOrderService: Provides clean interface for modern applications
LegacyOrderAdapter: Handles communication with legacy system
OrderTranslator: Manages data format conversions
LegacyOrderService: Represents the external legacy system
