+  support any number of regions without complex configuration.
+  
+* **Service Mesh/Service Segmentation** - Consul Connect enables secure service-to-service
+  communication with automatic TLS encryption and identity-based authorization. Applications 
+  can use sidecar proxies in a service mesh configuration to establish TLS 
+  connections for inbound and outbound connections without being aware of Connect at all. 
+  
 * **Service Discovery** - Consul makes it simple for services to register
   themselves and to discover other services via a DNS or HTTP interface.
   External services such as SaaS providers can be registered as well.
