🌩️ Multi-Cloud E-Commerce Demo

Welcome to the Multi-Cloud E-Commerce Demo developer documentation. This project provides a reference architecture for a distributed microservices system across multiple environments, demonstrating the practical application of Google Cloud networking, compute, and security products alongside multi-cloud integration.

🚀 Live Environment Hub

The entire platform is actively deployed and running natively on Google Cloud. You can directly interact with the live applications below, or jump straight into the cloud architecture using the Google Cloud Console.

🛍️ Online Boutique

The customer-facing frontend. Natively leverages Serverless Cloud Run and GKE under a Global Load Balancer.

💼 CRM Dashboard

Secure internal portal for managing orders over HTTPS. Built with Node.js and integrates Vertex AI Agents.

🛡️ Traffic Collector

Out-of-band Packet Mirroring dashboard tracking live security signatures asynchronously.

🎯 Educational Focus

This documentation is designed for Software Engineers (SWEs), Network Engineers, and Product Managers (PMs) to understand and evaluate advanced system design and network perimeters in practice.

By exploring this architecture, you will learn how to:

Apply Zero-Trust Networking: Understand the specific use cases for Private Service Connect (PSC) and Internal Load Balancing (ILB) to enforce strict boundaries.
Connect Serverless Workloads Securely: Compare Direct VPC Egress with Serverless Connectors.
Implement Multi-Cloud Integrations: Route secure communication across boundaries utilizing Dedicated Interconnects or HA VPNs.
Govern B2B External Access: Use Apigee API Management to precisely protect internal workloads.
Enable Event-Driven Operations: Utilize Google Cloud Pub/Sub and BigQuery for data pipelines.
Integrate AI & Intelligence: Build workflows utilizing Vertex AI Agent Engine and modern language proxies.
Network Observability & Security: Deploy Out-of-Band (OOB) Packet Mirroring for real-time Deep Packet Inspection.
