 A service mesh specializes in the network management of services and the communication between services.
 The mesh is responsible for keeping track of services and their health status, IP address, and traffic routing and ensuring all traffic between services is authenticated and encrypted.
-Unlike API gateways, a service mesh will track all registered services' lifecycle and ensure requests are routed to healthy instances of the service.
+Unlike some API gateways, a service mesh will track all registered services' lifecycle and ensure requests are routed to healthy instances of the service.
 API gateways are frequently deployed alongside a load balancer to ensure traffic is directed to healthy and available instances of the service.
 The mesh reduces the load balancer footprint as routing responsibilities are handled in a decentralized manner.
 
 API gateways can be used with a service mesh to bridge external networks (non-mesh) with a service mesh.

 A service mesh can be connected to another service mesh in another data center or VPC to form a federated mesh.

 This topic provides configuration reference information for the ingress gateway configuration entry. An ingress gateway is a type of proxy you register as a service in Consul to enable network connectivity from external services to services inside of the service mesh. Refer to [Ingress gateways overview](/consul/docs/connect/gateways/ingress-gateway) for additional information.

+API gateways enable network access, from outside a service mesh, to services running in a Consul service mesh. The
+systems accessing the services in the mesh, may be within your organizational network or external to it. This type of
+network traffic is commonly called _north-south_ network traffic because it refers to the flow of data into and out of
+a specific environment.
+
+API gateways solve the following primary use cases:
+
+- **Control access at the point of entry**: Set the protocols of external connection
+  requests and secure inbound connections with TLS certificates from trusted
+  providers, such as Verisign and Let's Encrypt.
+- **Simplify traffic management**: Load balance requests across services and route
+  traffic to the appropriate service by matching one or more criteria, such as
+  hostname, path, header presence or value, and HTTP method.
