​
Overview

Multi-Cloud Manager provides unified network management across Azure and Google Cloud Platform. Create and manage virtual networks, subnets, and network configurations from a single interface.

​
Supported Cloud Providers

Azure VNets

Manage Azure Virtual Networks with address spaces and subnets

GCP VPCs

Create and configure Google Cloud VPC networks with custom subnets

​
Key Features

​
Unified Network Discovery

Automatically discover and list all virtual networks across your cloud accounts:
  • Azure: Lists VNets across all subscriptions and resource groups
  • GCP: Aggregates VPCs across all projects with subnet details

​
Network Creation

Create virtual networks with provider-specific configurations:
  • Azure VNets: Configure address spaces, location, and resource groups
  • GCP VPCs: Set routing modes (REGIONAL/GLOBAL) and subnet modes

​
Subnet Management

Define network segments with custom IP address ranges:
  • Create subnets within existing virtual networks
  • Configure IP CIDR ranges for network isolation
  • Manage subnet placement across regions

​
Network Architecture

​
Azure Virtual Networks

    └── Virtual Network (VNet)

        └── Subnets
            ├── Subnet 1: 10.0.1.0/24
            └── Subnet 2: 10.0.2.0/24

        └── Region us-east1: 10.0.2.0/24

​
Network Isolation

​
Azure Isolation

Virtual Networks in Azure provide network isolation through:
  • Subscription-level isolation: VNets are scoped to subscriptions
  • Resource group organization: Group related network resources
  • Address space segregation: Non-overlapping CIDR blocks
  • Subnet segmentation: Isolate workloads within VNets

​
GCP Isolation

VPC networks in GCP offer isolation via:
  • Project-level isolation: VPCs are project-scoped resources
  • Custom subnet mode: Manual control over subnet creation
  • Regional subnets: Geographic isolation of resources
  • Firewall rules: Network-level access controls

​
Connectivity Options

​
Within the Same Cloud

Azure:
  • VNet peering for VNet-to-VNet connectivity
  • VPN Gateway for encrypted connections
  • ExpressRoute for dedicated connections
GCP:
  • VPC peering for VPC-to-VPC connectivity
  • Cloud VPN for encrypted tunnels
  • Cloud Interconnect for dedicated connections

​
Cross-Cloud Connectivity

Connect networks across cloud providers:
  • Site-to-site VPN tunnels between Azure and GCP
  • Third-party SD-WAN solutions
  • Direct interconnect through co-location facilities

​
API Integration

Multi-Cloud Manager uses native cloud SDKs: Azure:
  • NetworkManagementClient from Azure SDK for Python
  • Authenticated using FlaskCredential with OAuth tokens
  • Reference: /workspace/source/project/backend/azure_modules/vnet.py:54
GCP:
  • compute_v1.NetworksClient from Google Cloud Compute API
  • Session-based credentials with refresh tokens
  • Reference: /workspace/source/project/backend/gcp/vpcs.py:102

​
