+# Considerations for deployment in Azure public MEC Preview
+
+Azure public multi-access edge compute (MEC) Preview sites are small-footprint extensions of Azure. They're placed in or near mobile operators' data centers in metro areas, and are designed to run workloads that require ultra-low latency while being attached to the mobile network. This article focuses on the considerations that customers should plan for before they deploy applications in the Azure public MEC.
+
+## Prerequisites
+
+- If you don't have an Azure subscription, create a [free account](https://azure.microsoft.com/free/?WT.mc_id=A261C142F) before you begin.
+
+- Add an allowlisted subscription to your Azure account, which allows you to deploy resources in Azure public MEC. If you don't have an active allowed subscription, contact the [Azure public MEC product team](https://aka.ms/azurepublicmec).
+
+## Best practices
+
+For Azure public MEC, follow these best practices:
+
+- Deploy only the components of the application that are latency sensitive or need low latency compute at the Azure public MEC. Deploy all other components of the application that perform control plane and management plane functionalities in the parent region.
+
+- Because Azure public MEC sites are connected to the Telco network, accessing resources deployed in it over the internet isn't allowed. To access VMs deployed in the Azure public MEC, deploy jump box virtual machines (VMs) or Azure Bastion in a virtual network (VNet) in the parent region.
+
+- For compute resources in the Azure public MEC, deploy Azure Key Vault in the Azure region to provide secrets management and key management services.
+
+- Use VNet peering between the VNets in the Azure public MEC and the VNets in the parent region. IaaS resources can communicate privately through the Microsoft network and don't need to access the public internet.
+
+## Azure public MEC architecture
+
+Deploy application components that require ultra-low latencies in the Azure public MEC, and components that are non-latency sensitive in the Azure region.
+
+### Azure region
+
+The Azure region should run the components of the application that perform control and management plane functions and aren't latency sensitive.
+
+For example:
+
+#### Azure database and storage
+
+- Azure databases: Azure SQL, Azure Database for MySQL, and so on
+- Storage accounts
+- Azure Blob Storage
+
+#### AI and Analytics
+
+- Azure Machine Learning Services
+- Azure Analytics Services
+- Power BI
+- Azure Stream Analytics
+
+#### Identity services
+
+- Azure Active Directory
+
+#### Secrets management
+
+- Azure Key Vault
+
+### Azure public MEC
+
+Azure public MEC should run components that are latency sensitive and need faster response times from compute resources. To do so, run your application on compute services such as Azure Virtual Machines and Azure Kubernetes Service in the public MEC.
+
+## Availability and resiliency
+
+Applications you deploy in the Azure public MEC can be made available and resilient by using the following methods:
+
+- Deploy resources in active/standby, with primary resources in the Azure public MEC and standby resources in the parent Azure region. If there's a failure in the Azure public MEC, the resources in the parent region become active.
+
+- Use the [Azure backup and disaster recover solution](/azure/architecture/framework/resiliency/backup-and-recovery), which provides [Azure Site Recovery](/azure/site-recovery/site-recovery-overview) and Azure Backup features. This solution:
+  - Actively replicates VMs from the Azure public MEC to the parent region and makes them available to fail over and fail back if there's an outage.
+  - Backs up VMs to prevent data corruption or lost.
+
+>[!NOTE] The Azure Azure backup and disaster recover solution for Azure public MEC supports only Azure Virtual Machines.
+
+A trade-off exists between availability and latency. Failing over the application from the Azure public MEC to the Azure region ensures that the application is available, but might increase the latency to the application.

+# Key concepts for Azure public MEC Preview
+
+This document describes important concepts for Azure public multi-access edge compute (MEC) Preview.
+
+## ExtendedLocation
+
+All resource providers provide an additional field called [extendedLocation](/javascript/api/@azure/arm-compute/extendedlocation?view=azure-node-latest), which you use to deploy resources in the Azure public MEC.
+
+### Azure Edge Zone ID
+
+Every Azure public MEC site has an Azure Edge Zone ID. This ID is one of the attributes for `extendedLocation` to differentiate sites.
+
+### Azure CLI and SDKs
+
+SDKs for services supported in Azure public MEC have been updated. You can follow the [Python](tutotrial-create-vm-using-python-sdk.md), [Go](Tutorial-Crete-VM-using-GoSdk.md) and [Azure CLI](quickstart-create-vm-cli.md) documents that provide a guide on how to use them for deployments.
+
+### ARM templates
+
+You can use ARM Templates to deploy resources in the Azure public MEC. Here's' an example of how `extendedLocation` is used in an Azure Resource Manager (ARM) template to deploy a virtual machine (VM):
+
+```json
+{
+  ...
+  "type": "Microsoft.Compute/virtualMachines"
+  "extendedLocation": {
+    "type": "EdgeZone",
+    "name": <edgezoneid>,
+    }
+  ...
+}
+```
+
+## Parent region
+
+Every Azure public MEC site is associated with a parent Azure region. This region hosts all the control plane functions associated with the services running in the Azure public MEC. The following table lists all the active Azure public MEC sites, their Edge Zone ID and associated parent region.
+
+Telco Provider | Azure public MEC Name | Edge Zone ID | Parent region
+-------------- | --------------------- | ------------ | -------------
+AT&T | ATT Atlanta A | attatlanta1 | East US 2
+AT&T | ATT Dallas A | attdallas1 | South Central US
+
+## Azure services
+
+### Azure virtual machines
+
+Azure public MEC supports specific compute and GPU VM SKUs. The table below provides a list of all VM sizes supported:
+
+Type | Series | VM size
+---- | ------ | -------
+VM | D-series | D2s_v3, D4s_v3, D8s_v3
+VM | E-series | E4s_v3, E8s_v3
+GPU | NCasT4_v3-series | Standard_NC4asT4_v3, Standard_NC8asT4_v3
+
+### Public IP
+
+Azure public MEC allows users to create public IPs that can be then associated with resources such as Azure Virtual Machines, Azure Standard Load Balancer, and Azure Kubernetes Clusters. All the Azure public MEC IPs are the Standard public IP SKU.
+
+### Azure Bastion
+
+Azure Bastion is a service you deploy that lets you connect to a virtual machine by using your browser and the Azure portal. To access a VM deployed in the Azure public MEC, the Bastion host must be deployed in a VNet in the parent region of the Azure public MEC site.
+
+### Azure Load Balancer
+
+The Azure public MEC supports the "Standard" Load Balancer SKU.
+
+### Network Security Groups
+
+Network Security Groups should be created in the parent region, and then can be associated to resources created in the Azure public MEC.
+
+### Resource Groups
+
+Resource Groups should  be created in the parent Azure region, and then can be associated to resources created in the Azure public MEC.
+
+### Storage Services
+
+Azure public MEC only supports creating Standard SSD Managed DiskS. All other storage services are currently not supported in the public MEC.
+
+### Default outbound access
+
+Because [default outbound access](/azure/virtual-network/ip-services/default-outbound-access) isn't supported on the public MEC, use a method in the following table to manage your outbound connectivity:
+
+\# | Method
+--- | -----
+1 | Use the frontend IP addresses of a Load Balancer for outbound via outbound rules.
+2 | Assign a public IP to the VM.
+
+### DNS Resolution
+
+By default, all services running in the Azure public MEC use the DNS infrastructure in the Azure parent region.
