Purpose
Notes for Amazon VPC Lattice service-to-service connectivity, authorization, and observability across VPCs/accounts.
Key Concepts
- A service network is the logical boundary for services and resource configurations.
- Clients reach the network through VPC association or a service-network VPC endpoint.
- Use auth policies and observability deliberately; do not treat connectivity as authorization.
When To Consider
- Microservices that span VPCs/accounts and need simpler application networking.
- Modernization paths where service discovery, connectivity, and monitoring should be centralized.
