Service networks in VPC Lattice
A service network is a logical boundary for a collection of services. Services associated with the network can be authorized for discovery, connectivity, accessibility, and observability. To make requests to services in the network, your service or client must be in a VPC that is associated with the service network.
The following diagram shows the key components of a typical service network within Amazon VPC Lattice. Check marks on the arrows indicate that the services and the VPC are associated with the service network. Clients in the VPC associated with the service network can communicate with both services through the service network.
You can associate one or more services with multiple service networks. You can also associate multiple VPCs with one service network. However, each VPC can be associated with only one service network.
In the following diagram, the arrows represent the associations between services and service networks, as well as associations between the VPCs and service networks. You can see that multiple services are associated to multiple service networks, and multiple VPCs are associated to each service network. However, the red x mark in the diagram shows that each VPC can have no more than one association to a service network.
