☁️ Cloud Architecture

The platform is designed around Google Cloud Platform (GCP).

Each environment is isolated using a dedicated GCP project.

Environment Strategy

Environment	Purpose	GCP Project
🟢 DEV	Development & integration	`ecommerce-dev`
🟡 STAGING	Pre-production validation	`ecommerce-staging`
🔴 PROD	Production	`ecommerce-prod`

Current implementation: DEV environment is being established first. STAGING and PROD will be introduced after the DEV architecture and CI/CD pipeline are stable.

📦 Repository Architecture

The GitHub organization follows a repository-per-service/application strategy.

🔐 Security Model

Security is treated as a first-class component of the platform.

GitHub

Two-factor authentication
Protected main branch
Pull-request based development
CODEOWNERS
Required CI checks
GitHub Actions security controls
Secret management through GitHub/GCP
Least-privilege access

GCP

Dedicated projects per environment
IAM least privilege
Dedicated deployment identities
Workload Identity Federation
No long-lived service-account keys
Environment isolation
Artifact scanning

Secrets

Sensitive information must never be committed to Git.

❌ Passwords
❌ API keys
❌ Private keys
❌ Service account JSON
❌ Database credentials
❌ Access tokens

🌿 Git Branch Strategy

The project follows a controlled Git workflow.

 │
 ├── bugfix/*
 │
 ├── release/*

 └── hotfix/*

Hotfix Strategy

Production hotfixes are version controlled independently.

v1.1.1
v1.1.2
v1.1.3
...
v1.1.7

A specific release can be deployed without automatically deploying later changes.

Example:

STAGING → v1.1.10

PROD    → v1.1.1

HOTFIX  → v1.1.7

This allows controlled production deployments and rollback.

🏷️ Versioning Strategy

Deployable artifacts use semantic versioning.

MAJOR.MINOR.PATCH

1.1.7

Examples:

v1.0.0
v1.0.1
v1.1.0
v1.1.7
v2.0.0

Docker images are tagged using immutable version identifiers.

product-service:v1.1.7

The same artifact can then be promoted across environments:

DEV
 │
 ▼
STAGING
 │
 ▼
PRODUCTION

This prevents rebuilding different artifacts for each environment.

🐳 Container Strategy

Applications are packaged as Docker containers.

Docker Build
    │
    ▼
Docker Image
    │
    ▼
Security Scan
    │
    ▼
Artifact Registry
    │
    ▼
Cloud Run / Kubernetes

☸️ Runtime Strategy

The platform supports multiple container execution models.

Cloud Run

Used for lightweight, serverless container workloads.

     ▼
Artifact Registry
     │
     ▼
Cloud Run

Kubernetes

Used where advanced orchestration capabilities are required.

Docker Image
     │
     ▼
Artifact Registry
     │
     ▼
Google Kubernetes Engine

The runtime choice will depend on the workload and architectural requirements.

🔥 Frontend Platform

Frontend applications can be deployed using:

Angular
React
Vue

Deployment options include:

Firebase Hosting
        │
        ▼
Frontend Applications

Backend workloads:

Cloud Run / GKE

This keeps frontend and backend deployment responsibilities independent.

📊 Observability

The platform is designed to support:

Application Metrics
        │
        ├── Prometheus
        │
        └── Grafana

Distributed Tracing
        │
        ├── OpenTelemetry
        ├── Jaeger
        └── Zipkin

Centralized Logging
        │
        └── ELK / Cloud Logging

Observability will be introduced incrementally as the platform evolves.

📚 Engineering Standards

Development follows enterprise engineering practices.

SOLID principles
Design patterns
Static analysis

Phase 3 — GitHub Actions

Phase 4 — STAGING

Phase 5 — PRODUCTION

🎯 Current Focus

DEV Environment First

🤝 Engineering Philosophy

The platform is designed with the following principles:

Automate everything that can be automated.

Build once, promote the same artifact.

Secure by default.

Infrastructure should be reproducible.

Every deployment should be traceable and reversible.

DEV, STAGING, and PROD must remain isolated.
