Multi-Cloud Connectivity & Integration Guide

AI-Assisted Documentation

The Practitioner's Guide to Enterprise Cloud Integration

About This Documentation

This comprehensive guide provides detailed technical documentation for implementing enterprise-grade multi-cloud connectivity architectures, combining GCP Vertex AI, Azure SASE, and Cisco SD-WAN Cloud OnRamp in production environments.

Project Scope

This documentation covers the complete design, implementation, and validation of a multi-cloud hybrid architecture:

  • GCP Vertex AI Platform — AI-powered Webex Contact Center (WxCC) analytics for 175 agents
  • Azure SASE Platform — Secure Access Service Edge for Office 365 and global user access
  • Cisco SD-WAN Cloud OnRamp — Automated cloud connectivity for SaaS, IaaS, and SASE integration
  • 19-Site Enterprise Network — 6 hub sites + 13 branch locations across APAC, EMEA, and Americas
