Data Replication Strategies

DynamoDB Global Tables

• Replication Lag: <1 second typical
• Conflict Resolution: Last-writer-wins
• Cost: Standard DynamoDB pricing in each region
• Use Case: Real-time multi-region writes

S3 Cross-Region Replication (CRR)

• Replication Lag: <15 minutes typical
• Versioning: Required
• Cost: Data transfer + storage in secondary region
• Use Case: Static assets, backups, compliance

Aurora Global Database

• Replication Lag: <1 second typical
• RPO: <1 second
• RTO: <1 minute
• Use Case: Relational database workloads

Failover Procedures

Automated Failover (Route 53)

Trigger: Health check failure (3 consecutive failures at 30s intervals)
Detection Time: 90 seconds
DNS TTL: 60 seconds
Total Failover Time: <3 minutes

Manual Failover (Disaster Scenario)

# 1. Verify secondary region health
aws cloudwatch get-metric-statistics --region eu-west-1 ...

# 2. Update Route 53 to point to secondary
aws route53 change-resource-record-sets --hosted-zone-id Z123 ...

# 3. Verify traffic routing
curl -I https://example.com

# 4. Notify stakeholders
aws sns publish --topic-arn arn:aws:sns:us-east-1:123456789012:alerts ...

# Total Time: <5 minutes

## 8. Mermaid Diagram Standards

### 8.1 Required Diagram Types

Every FUTURE_ARCHITECTURE.md MUST include **minimum 8 diagrams**:

1. ✅ **C4 Context Diagram** (C4Context)
2. ✅ **C4 Container Diagram** (C4Container)
3. ✅ **Multi-Region Architecture** (graph TB/LR)
4. ✅ **Security Services Integration** (graph TB)
5. ✅ **Data Flow Diagram** (graph TB/LR)
6. ✅ **State Diagram** (stateDiagram-v2)
7. ✅ **Sequence Diagram** (sequenceDiagram)
8. ✅ **Deployment Pipeline** (graph LR)

### 8.2 Mermaid Diagram Quality Standards

#### 8.2.1 C4 Diagrams (Context & Container)

**Syntax:**
```mermaid
C4Context
  title [Descriptive Title]
  
  Person(id, "Role Name", "Description")
  System(id, "System Name", "Description")
  System_Ext(id, "External System", "Description")
  System_Boundary(id, "Boundary Name") { }
  
  Rel(from, to, "Action", "Protocol")
  BiRel(from, to, "Bidirectional action", "Protocol")
  
  UpdateLayoutConfig($c4ShapeInRow="3", $c4BoundaryInRow="1")

Requirements:

• Use UpdateLayoutConfig() for consistent layout
• Include protocol/technology in relationship labels
• Use BiRel() for bidirectional data flows
• Use System_Boundary() to group related components

8.2.2 Graph Diagrams (TB/LR)

Syntax:

graph TB
    subgraph "Group Name"
        Node1[Label]
        Node2[Label]
    end
    
    Node1 --> Node2
    Node1 -.->|Async| Node3
    
    style Node1 fill:#4caf50
    style Node2 fill:#2196f3

Requirements:

• Use subgraph to group related components
• Use solid arrows (-->) for primary flows
• Use dashed arrows (-.->) for secondary/async flows
• Include labels on arrows for clarity
• Apply color styling consistently

8.2.3 Sequence Diagrams

Syntax:

sequenceDiagram
    participant User
    participant Frontend
    participant API
    participant Database
    
    User->>Frontend: Click button
    Frontend->>API: POST /endpoint
    API->>Database: Query data
    Database-->>API: Return results
    API-->>Frontend: JSON response
    Frontend-->>User: Display data
    
    Note over API,Database: Async operation

Requirements:

• Use meaningful participant names
• Include request/response protocols
• Add notes for important details
• Use -->> for return messages

8.2.4 State Diagrams

Syntax:

stateDiagram-v2
    [*] --> Initial
    Initial --> Active: User action
    Active --> Processing: Submit
    Processing --> Complete: Success
    Processing --> Error: Failure
    Error --> Active: Retry
    Complete --> [*]
    
    note right of Processing: 30 second timeout

Requirements:

• Use stateDiagram-v2 for modern syntax
• Include transition labels
• Add notes for important timing/conditions
• Show all possible state transitions

8.3 Color Scheme Standards

Standard Color Palette:

Primary: #4caf50   /* Green - Active/Primary */
Secondary: #2196f3 /* Blue - Supporting */
Warning: #ff9800   /* Orange - Attention */
Danger: #f44336    /* Red - Critical */
Accent: #9c27b0    /* Purple - External */
Info: #00bcd4      /* Cyan - Information */
Neutral: #90caf9   /* Light Blue - Passive */

Color Usage Guidelines:

• Green (#4caf50): Primary components, active state, success
• Blue (#2196f3): Data stores, supporting services
• Orange (#ff9800): Security services, attention required
• Red (#f44336): Error states, critical alerts
• Purple (#9c27b0): External systems, third-party integrations
• Cyan (#00bcd4): Information, metadata
• Light Blue (#90caf9): Passive/standby components

8.4 Diagram Complexity Guidelines

Simple Diagrams (5-10 nodes):

• High-level overviews
• Executive summaries
• Single responsibility focus

Medium Diagrams (10-20 nodes):

• Technical architecture
• Component interactions
• Standard complexity

Complex Diagrams (20-30 nodes):

• Comprehensive system views
• Multiple subsystems
• Maximum recommended complexity

⚠️ Warning: Diagrams with >30 nodes become unreadable. Split into multiple focused diagrams instead.

8.5 Diagram Documentation Requirements

Every diagram MUST include:

1. Title: Descriptive heading above diagram
2. Focus Statement: 1-2 sentences explaining what the diagram shows
3. Legend/Key: If using custom colors or symbols
4. Highlights Section: Bullet points explaining key elements (after diagram)

Example:

## 🌐 Future C4 Context Diagram - AWS Serverless Ecosystem

**💼 Business Focus:** Illustrates how the enhanced platform serves multiple stakeholder 
roles with AWS-powered backend services supporting enterprise-scale security assessment.

**🔒 Security Focus:** Defines trust boundaries with AWS security services providing 
comprehensive threat protection across the entire stack.
