Before you run the pod deployment wizard, verify that your environment satisfies these prerequisites. You must have the following items so that you can provide the requested values in the pod deployment wizard and proceed through the wizard.
Prerequisites for All Deployments
- Verify that all of the preparatory tasks are completed, as described in Preparing to Deploy a Horizon Cloud Pod Into Microsoft Azure.
- Verify that you have the subscription information, as described in Subscription-Related Information for the Horizon Cloud Pod Deployment Wizard.
- Verify that you have an existing virtual network in your Microsoft Azure subscription, and in the region in which you are deploying the pod, as described in Configure the Required Virtual Network in Microsoft Azure.
Important: Not all Microsoft Azure regions support GPU-enabled virtual machines. If you want to use the pod for GPU-capable desktops or remote applications, ensure that the Microsoft Azure region you select for the pod provides for those NV-series VM types that you want to use and which are supported in this Horizon Cloud release. See the Microsoft documentation at https://azure.microsoft.com/en-us/regions/services/ for details.
- Verify that your VNet is configured to point to a DNS that can resolve external addresses. The pod deployer must be able to reach external addresses in the Horizon Cloud control plane to securely download the pod software into your Microsoft Azure environment.
- Verify that the pod deployer's DNS, ports, and protocols requirements are met, as described in DNS Requirements for a Horizon Cloud Pod in Microsoft Azure and Ports and Protocols Requirements for a Horizon Cloud Pod at the September 2019 Release's Manifest or Later.
- If you require use of a proxy for outbound Internet access, verify you have the networking information for your proxy configuration and the authentication credentials it requires, if any. The pod deployment process requires outbound Internet access.
- Verify that you have the information for at least one NTP server that you want the pod to use for time synchronization. The NTP server can be a public NTP server or your own NTP server that you set up for this purpose. The NTP server you specify must be reachable from the virtual network you configured. When you plan to use an NTP server using its domain name instead of a numeric IP address, also ensure that the DNS configured for the virtual network can resolve the NTP server's name.
- If you do not want the deployer to automatically create the subnets it needs, verify that the required subnets have been created in advance and exist on the VNet. For the steps to create the required subnets in advance, see In Advance of Pod Deployment, Create the Horizon Cloud Pod's Required Subnets on your VNet in Microsoft Azure and When Using Existing Subnets for a Horizon Cloud Pod in Microsoft Azure.
Caution: The subnets you manually create on your VNet in advance for the pod deployment must remain empty. Do not put any resources on these subnets or otherwise use any of the IP addresses. If an IP address is already in use on the subnets, the pod might fail to deploy.
- If you are going to have the deployer create the required subnets, verify that you know the address ranges you are going to enter into the wizard for the management subnet, desktop subnet, and DMZ subnet. The DMZ subnet is required when you want the external Unified Access Gateway configuration. Also verify that those ranges do not overlap. You enter the address ranges using CIDR notation (classless inter-domain routing notation). The wizard will display an error if the entered subnet ranges overlap. For the management subnet range, a CIDR of at least /27 is required. For the DMZ subnet range, a CIDR of at least /28 is required. If you want to keep the management and DMZ subnet ranges co-located, you can specify the DMZ subnet range similar to the management subnet with an IP specified. For example, if the management subnet is 192.168.8.0/27, a matching DMZ subnet would be 192.168.8.32/27.
Important: The CIDRs you enter in the wizard's fields must be defined so that each combination of prefix and bit mask results in an IP address range having the prefix as the starting IP address. Microsoft Azure requires that the CIDR prefix be the start of the range. For example, a correct CIDR of 192.168.182.48/28 would result in an IP range of 192.168.182.48 to 192.168.182.63, and the prefix is the same as the starting IP address (192.168.182.48). However, an incorrect CIDR of 192.168.182.60/28 would result in an IP range of 192.168.182.48 to 192.168.182.63, where the starting IP address is not the same as the prefix of 192.168.182.60. Ensure that your CIDRs result in IP address ranges where the starting IP address matches the CIDR prefix.
- If you are going to have the deployer create the required subnets, verify that subnets with those address ranges do not already exist on the VNet. In this scenario, the deployer itself will automatically create the subnets using the address ranges you provide in the wizard. If the wizard detects subnets with those ranges already exist, the wizard will display an error about overlapping addresses and will not proceed further. If your VNet is peered, also verify that the CIDR address spaces that you plan to enter in the wizard are already contained in the VNet's address space.
Prerequisites When Creating a Workspace ONE Access Cloud Tenant During Pod Deployment
The pod deployment wizard has an option to create a Workspace ONE Access tenant in the Workspace ONE Access Cloud service as part of the pod deployment. With that option selected, the pod deployment process creates and configures a tenant in the Workspace ONE Access Cloud service. After some post-tenant-creation configuration steps, you can use that Workspace ONE Access tenant with the pods you deploy in Microsoft Azure using the same Horizon Cloud account.
If you plan to use this option in the wizard, verify that you know:
- The name of the Workspace ONE Access data center region in which you want the Workspace ONE Access tenant created. In the pod deployment wizard, you will select this data center region from a drop-down menu.
- The name you want to use for your Workspace ONE Access tenant.
- A user name that you want for the tenant's admin account.
- Email address. The email address you enter in the wizard will be associated with the tenant's admin account. The welcome email is sent to that email address when the system has created the Workspace ONE Access tenant.
A best practice is to use the same email that is the one reflected in the My VMware account that is associated with your VMware Horizon Cloud Service on Microsoft Azure customer account record. This best practice provides for the welcome email about the new tenant going to the same email address where the ones from Horizon Cloud are sent. That is, when you log into the Administration Console to deploy your first pod, you log in with a My VMware name in the form of
email@example.com described in Start the Pod Deployment Wizard. Using that same name as the email address for the Workspace ONE Access tenant can make the initial experience easier.
Prerequisites When Deploying With a Unified Access Gateway Configuration
If you are planning to have the pod use a Unified Access Gateway configuration, you must provide:
- The fully qualified domain name (FQDN) which your end users will use to access the service. If you are going to deploy the pod with both the external and internal Unified Access Gateway configuration types and you want to use the same FQDN for both, you must determine how to route the incoming end-user client traffic to the appropriate load balancer. In this scenario, you need to set up the routing so that client traffic from the Internet is routed to the Microsoft Public Load Balancer and client traffic from your intranet is routed to the Microsoft Internal Load Balancer.
Important: This FQDN cannot contain underscores. In this release, connections to the Unified Access Gateway instances will fail when the FQDN contains underscores.
- A signed SSL server certificate (in PEM format) based on that FQDN. The Unified Access Gateway capabilities require SSL for client connections, as described in the Unified Access Gateway product documentation. The certificate must be signed by a trusted Certificate Authority (CA). The single PEM file must contain the full entire certificate chain with the private key. For example, the single PEM file must contain the SSL server certificate, any necessary intermediate CA certificates, the root CA certificate, and private key. OpenSSL is a tool you can use to create the PEM file.
Important: All certificates in the certificate chain must have valid time frames. The Unified Access Gateway VMs require that all of the certificates in the chain, including any intermediate certificates, have valid time frames. If any certificate in the chain is expired, unexpected failures can occur later as the certificate is uploaded to the Unified Access Gateway configuration.
- If you are deploying with an external Unified Access Gateway configuration, you must specify a DMZ (demilitarized zone) subnet. You can provide for this DMZ subnet by one of two ways:
- Creating the DMZ subnet in advance on the VNet. With this method, you also have to create the management and desktop tenant subnets in advance. See the steps in In Advance of Pod Deployment, Create the Horizon Cloud Pod's Required Subnets on your VNet in Microsoft Azure.
- Having the deployer automatically create the DMZ subnet during deployment. With this method, you must have the address range you are going to enter into the wizard for the DMZ subnet and verify that the range does not overlap with the ranges for the management and desktop tenant subnets. You enter the address ranges using CIDR notation (classless inter-domain routing notation). The wizard will display an error if the entered subnet ranges overlap. For the DMZ subnet range, a CIDR of at least /28 is required. If you want to keep the management and DMZ subnet ranges co-located, you can specify the DMZ subnet range the same as the management subnet with an IP specified. For example, if the management subnet is 192.168.8.0/27, a matching DMZ subnet would be 192.168.8.32/27. Also see the important note in Prerequisites for All Deployments about ensuring the IP address range has a combination of prefix and bit mask that results in the range having the prefix as the starting IP address.
- If you are deploying with an external Unified Access Gateway configuration and you want to disable having a public IP address for the configuration's load balancer, you must specify an IP address that you have mapped in your DNS settings to the FQDN which your end users will use for PCoIP connections in their Horizon clients.
For more information about the PEM file considerations required by Unified Access Gateway, see Convert a Certificate File to the PEM Format Required for Pod Deployment.
Prerequisites When Deploying With an External Unified Access Gateway Configuration Using its Own VNet or Subscription Separate from the Pod's VNet or Subscription
Along with the above prerequisites when deploying with a Unified Access Gateway configuration, these prerequisites are specific to the use case of deploying the external gateway in its own VNet or own subscription. Using its own subscription is a special case of using its own VNet, because the separate subscription must have its own VNet, because VNets are scoped to a subscription.
- The VNet for the gateway must be peered with the pod's VNet.
- Verify that either the required subnets have been created in advance and exist on the VNet, or that the CIDR address spaces that you plan to enter in the wizard are already contained in the VNet's address space. Because the VNets are peered, the deployer will not be able to expand the VNet automatically if you enter into the wizard CIDR address spaces that are not already contained in the VNet's address space. If that happens, the deployment process will fail.
Tip: The best practice is to create the subnets in advance. For the steps to create the required subnets in advance, see In Advance of Pod Deployment, Create the Horizon Cloud Pod's Required Subnets on your VNet in Microsoft Azure and When Using Existing Subnets for a Horizon Cloud Pod in Microsoft Azure.
- If you are using a separate subscription for the external gateway, verify that you have the subscription information, as described in Subscription-Related Information for the Horizon Cloud Pod Deployment Wizard.
Prerequisites When Deploying With a Two-Factor Authentication Configuration
If you are planning to use the two-factor authentication capability, or use it with an on-premises two-factor authentication server, verify that you have the following information used in your authentication server's configuration, so that you can provide it in the appropriate fields in the pod deployment wizard. If you have both a primary and secondary server, obtain the information for each of them.
- IP address or DNS name of the authentication server
- The shared secret that is used for encryption and decryption in the authentication server's protocol messages
- Authentication port numbers, typically the 1812 UDP port.
- Authentication protocol type. The authentication types include PAP (Password Authentication Protocol), CHAP (Challenge Handshake Authentication Protocol), MSCHAP1, MSCHAP2 (Microsoft Challenge Handshake Authentication Protocol, version 1 and 2).
Note: Check your RADIUS vendor's documentation for the authentication protocol that your RADIUS vendor recommends and follow their indicated protocol type. The pod's capability to support two-factor authentication with RADIUS is provided by the Unified Access Gateway instances, and Unified Access Gateway supports PAP, CHAP, MSCHAP1, and MSCHAP2. PAP is generally less secure than MSCHAP2. PAP is also a simpler protocol than MSCHAP2. As a result, even though most RADIUS vendors are compatible with the simpler PAP protocol, some RADIUS vendors are not as compatible with the more secure MSCHAP2.
