Use Amazon VPC Lattice to streamline and secure TCP resource connectivity across multiple AWS Accounts

This article provides a comprehensive guide to using Amazon VPC Lattice for establishing secure TCP resource connectivity across multiple AWS accounts in an AWS Organizations environment. The key highlights include:

• Creating a centralized service network in a dedicated networking account
• Sharing the service network with other accounts using AWS Resource Access Manager (RAM)
• Configuring cross-account RDS database access using VPC Lattice components
• Setting up resource gateways, resource configurations, and VPC endpoints
• Implementing strict security controls using security groups and network configurations

The step-by-step guide demonstrates how to: 1. Enable DNS settings across accounts 2. Create a service network in the networking account 3. Set up an RDS database in the databases account 4. Configure a service network endpoint in the applications account

The solution enables secure, scalable cross-account resource sharing with granular access controls and simplified network management.
