Infrastructure

Cloud architecture, database design, security, DevOps, and ERP integration.

Components

AWS Architecture

Cloud-native infrastructure:

• Serverless patterns (Lambda, Step Functions)
• Compute and networking
• Storage solutions
• Integration services
• Cost optimization

Database

Data layer design:

• Prisma Postgres - Managed PostgreSQL by Prisma
• Prisma Accelerate - Built-in edge caching (300+ locations)
• Connection pooling - Built-in, serverless-optimized
• Type-safe data modeling with Prisma schema
• See Tech Stack Options for CockroachDB alternative

Tech Stack Options - NEW

Technology alternatives and suggestions:

• Database: Prisma Postgres vs CockroachDB
• Cache: Prisma Accelerate + Redis (for inventory holds)
• Messaging: EventBridge vs Apache Kafka
• Identity: Cognito vs Auth0/Okta
• Protocol: REST/JSON vs gRPC

Security

Security architecture:

• Authentication and authorization
• Data encryption
• Network security
• Compliance frameworks

DevOps

Development and operations:

• CI/CD pipelines
• Infrastructure as Code
• Monitoring and observability
• Incident management

ERP Integration - NEW

Enterprise systems integration:

• Finance module (GL, AP/AR)
• HR module (Payroll, crew pay)
• Procurement module
• Integration patterns

Testing - NEW

Full flight simulation testing (SpaceX-style):

• Every PR runs complete passenger journey simulation
• Unit, integration, and E2E test suites
• 50+ edge case scenarios
• Disruption & recovery testing
• Load & concurrency testing
• CI/CD gate: all tests must pass

Architecture Principles

Cloud-Native

• Serverless-first approach
• Event-driven architecture
• Microservices decomposition
• Managed services preference

Resilience

• Multi-AZ deployment
• Circuit breakers
• Graceful degradation
• Disaster recovery

Scalability

• Horizontal scaling
• Auto-scaling policies
• Connection pooling
• Caching strategies

Security

• Zero trust model
• Encryption everywhere
• Least privilege access
• Audit logging

The Central Nervous System

Per the strategic blueprint, all systems connect through a unified data and process flow:
