 1. Use a D2v2 or higher SKU for the primary node type. It is recommended to pick a SKU with at least 50 GB hard disk capacity.
 1. Production clusters must be [secure](service-fabric-cluster-security.md). For an example of setting up a secure cluster, see this [cluster template](https://github.com/Azure-Samples/service-fabric-cluster-templates/tree/master/7-VM-Windows-3-NodeTypes-Secure-NSG). Use common names for certificates and avoid using self signed certs.
 1. Add [resource constraints on containers and services](service-fabric-resource-governance.md), so that they don't consume more than 75% of node resources. 
-1. Understand and set the [durability level](service-fabric-cluster-capacity.md#durability-characteristics-of-the-cluster). Silver or higher durability level is recommended for node types running stateful workloads.
-1. Understand and pick the [reliability level](service-fabric-cluster-capacity.md#reliability-characteristics-of-the-cluster) of the node type. Silver or higher reliability is recommended.
+1. Understand and set the [durability level](service-fabric-cluster-capacity.md#durability-characteristics-of-the-cluster). Silver or higher durability level is recommended for node types running stateful workloads, and required for production.

 1. Load and scale test your workloads to identify [capacity requirements](service-fabric-cluster-capacity.md) for your cluster. 
 1. Your services and applications are monitored and application logs are being generated and stored, with alerting. For example, see [Add logging to your Service Fabric application](service-fabric-how-to-diagnostics-log.md) and [Monitor containers with Azure Monitor logs](service-fabric-diagnostics-oms-containers.md).
