 The Open Service Mesh (OSM) add-on integrates with features provided by Azure as well as open source projects.

 ## Ingress
 
-Ingress allows for traffic external to the mesh to be routed to services within the mesh. With OSM, you can configure most ingress solutions to work with your mesh, but OSM works best with [Web Application Routing][web-app-routing], [NGINX ingress][osm-nginx], or [Contour ingress][osm-contour]. Open source projects integrating with OSM, including NGINX ingress and Contour ingress, are not covered by the [AKS support policy][aks-support-policy].

 ## Metrics observability
 
-Observability of metrics allows you to view the metrics of your mesh and the deployments in your mesh. With OSM, you can use [Prometheus and Grafana][osm-metrics] for metrics observability, but those integrations are not covered by the [AKS support policy][aks-support-policy].

 You can also integrate OSM with [Azure Monitor][azure-monitor].

 ## Automation and developer tools
 
-OSM can integrate with certain automation projects and developer tooling to help operators and developers build and release applications. For example, OSM integrates with [Flagger][osm-flagger] for progressive delivery and [Dapr][osm-dapr] for building applications. OSM's integration with Flagger and Dapr are not covered by the [AKS support policy][aks-support-policy].

 ## External authorization
 
-External authorization allows you to offload authorization of HTTP requests to an external service. OSM can use external authorization by integrating with [Open Policy Agent (OPA)][osm-opa], but that integration is not covered by the [AKS support policy][aks-support-policy].

 ## Certificate management
 
-OSM has several types of certificates it uses to operate on your AKS cluster. OSM includes its own certificate manager called Tresor, which is used by default. Alternatively, OSM allows you to integrate with [Hashicorp Vault][osm-hashi-vault], [Tresor][osm-tresor], and [cert-manager][osm-cert-manager], but those integrations are not covered by the [AKS support policy][aks-support-policy].
