Secure customer resource access in multi-tenant SaaS with Amazon VPC Lattice

This article discusses how to securely access customer resources in multi-tenant SaaS architectures using Amazon VPC Lattice and Resource Gateways. The key insights include:

• Two main architectural approaches for multi-tenant resource access:
  • One service network per tenant
  • Single shared service network
• VPC Lattice enables secure communication between applications across multiple accounts and VPCs
• Resource Gateways allow direct connectivity to resources without complex networking configurations
• Recommended to use Service Network Endpoints (SNEs) for most multi-tenant architectures
• Provides implementation guides for both architectural approaches

The solution offers SaaS providers a flexible and secure method to access customer resources across different network environments while maintaining strong isolation and security controls.
