Architecture Decision Records (ADR)

ADR-001: Microservice vs Monolithic Architecture

Status: Accepted

Context: Need to decide between microservice and monolithic architecture for AlphaPulse.

Decision: Hybrid approach - monolithic core with service boundaries that can be easily extracted to microservices.

Consequences:

ADR-002: Time-Series Database Selection

Status: Accepted

Context: Need specialized time-series storage for market data.

Decision: TimescaleDB (PostgreSQL extension)

Consequences:

ADR-003: Message Queue vs Direct Communication

Status: Accepted

Context: Inter-service communication pattern selection.

Decision: Direct API calls with Redis pub/sub for real-time events

Consequences:

This document provides a comprehensive view of the AlphaPulse architecture using various diagramming techniques. The diagrams cover:

  1. C4 Model: System context, containers, and components
  2. Data Flows: How data moves through the system
  3. Sequences: Step-by-step interaction flows
  4. Deployment: Infrastructure and deployment topology
  5. State Machines: Order and system state transitions
  6. Entity Relationships: Database schema overview
  7. Architecture Decisions: Key design choices
  8. Performance: Latency-critical paths and caching
  9. Security: Security layers and controls
  10. Monitoring: Observability architecture

Each diagram provides a different perspective on the system, helping developers, operators, and stakeholders understand how AlphaPulse works at various levels of abstraction.
