Learn how to connect AEM as a Cloud Service with your VPN to create secure communication channels between AEM and internal services.
Virtual Private Network (VPN) allows an AEM as a Cloud Service customer to connect the AEM environments within a Cloud Manager Program to an existing, supported VPN. This allows secure, and controlled connections between AEM as a Cloud Service and services within the customer’s network.
A Cloud Manager Program can only have a single network infrastructure type. Ensure that Virtual Private Network is the most appropriate type of network infrastructure for your AEM as a Cloud Service before executing the following commands.
Please note, connecting the build environment from Cloud Manager to a VPN is not supported. If you must access binary artifacts from a private repository, you must set up a secure and password-protected repository with a URL that is available on the public internet as described here.
The following are required when setting up Virtual Private Network:
For more details watch the following walkthrough for how to setup, configure, and obtain Cloud Manger API credentials, and how to use them to make a Cloud Manager API call.
This tutorial uses curl
to make the Cloud Manager API configurations. The provided curl
commands assume a Linux/macOS syntax. If using the Windows command prompt, replace the \
line-break character with ^
.
Start by enabling the Virtual Private Network on AEM as a Cloud Service.
First, determine the region in which the Advanced Networking is needed by using the Cloud Manager API listRegions operation. The region name
is required to make subsequent Cloud Manager API calls. Typically, the region the Production environment resides in is used.
Find your AEM as a Cloud Service environment’s region in Cloud Manager under the environment’s details. The region name displayed in Cloud Manager can be mapped to the region code used in the Cloud Manager API.
listRegions HTTP request
$ curl -X GET https://cloudmanager.adobe.io/api/program/{programId}/regions \
-H 'x-gw-ims-org-id: <ORGANIZATION_ID>' \
-H 'x-api-key: <CLIENT_ID>' \
-H 'Authorization: Bearer <ACCESS_TOKEN>' \
-H 'Content-Type: application/json'
Enable Virtual Private Network for a Cloud Manager Program using Cloud Manager APIs createNetworkInfrastructure operation. Use the appropriate region
code obtained from the Cloud Manager API listRegions
operation.
createNetworkInfrastructure HTTP request
$ curl -X POST https://cloudmanager.adobe.io/api/program/{programId}/networkInfrastructures \
-H 'x-gw-ims-org-id: <ORGANIZATION_ID>' \
-H 'x-api-key: <CLIENT_ID>' \
-H 'Authorization: Bearer <ACCESS_TOKEN>' \
-H 'Content-Type: application/json'
-d @./vpn-create.json
Define the JSON parameters in a vpn-create.json
and provided to curl via ... -d @./vpn-create.json
.
Download the example vpn-create.json. This file only an example. Configure your file as required based on the optional/required fields documented at enableEnvironmentAdvancedNetworkingConfiguration.

Wait 45-60 minutes for the Cloud Manager Program to provision the network infrastructure.
Check that the environment has finished Virtual Private Network configuration using the Cloud Manager API getNetworkInfrastructure operation, using the id
returned from the createNetworkInfrastructure HTTP request in the previous step.
getNetworkInfrastructure HTTP request
$ curl -X GET https://cloudmanager.adobe.io/api/program/{programId}/networkInfrastructure/{networkInfrastructureId} \
-H 'x-gw-ims-org-id: <ORGANIZATION_ID>' \
-H 'x-api-key: <CLIENT_ID>' \
-H 'Authorization: <YOUR_BEARER_TOKEN>' \
-H 'Content-Type: application/json'
Verify that the HTTP response contains a status of ready. If not yet ready recheck the status every few minutes.
Enable and configure the Virtual Private Network configuration on each AEM as a Cloud Service environment using the Cloud Manager API enableEnvironmentAdvancedNetworkingConfiguration operation.
enableEnvironmentAdvancedNetworkingConfiguration HTTP request
$ curl -X PUT https://cloudmanager.adobe.io/api/program/{programId}/environment/{environmentId}/advancedNetworking \
-H 'x-gw-ims-org-id: <ORGANIZATION_ID>' \

nonProxyHosts
declares a set of hosts for which port 80 or 443 should be routed through the default shared IP address ranges rather than the dedicated egress IP. nonProxyHosts
may be useful as traffic egressing through shared IPs may be further optimized automatically by Adobe.
For each portForwards
mapping, the advanced networking defines the following forwarding rule:
Proxy host | Proxy port | External host | External port | |
---|---|---|---|---|
AEM_PROXY_HOST |
portForwards.portOrig |
→ | portForwards.name |
portForwards.portDest |
If your AEM deployment only requires HTTP/HTTPS connections to external service, leave the portForwards
array empty, as these rules are only required for non-HTTP/HTTPS requests.
For each environment, validate the vpn routing rules are in effect using the Cloud Manager API’s getEnvironmentAdvancedNetworkingConfiguration operation.
getEnvironmentAdvancedNetworkingConfiguration HTTP request
$ curl -X GET https://cloudmanager.adobe.io/api/program/{programId}/environment/{environmentId}/advancedNetworking \
-H 'x-gw-ims-org-id: <ORGANIZATION_ID>' \
-H 'x-api-key: <CLIENT_ID>' \
-H 'Authorization: Bearer <ACCESS_TOKEN>' \
-H 'Content-Type: application/json'
Virtual private network proxy configurations can be updated using the Cloud Manager API’s enableEnvironmentAdvancedNetworkingConfiguration operation. Remember enableEnvironmentAdvancedNetworkingConfiguration
is a PUT
operation, so all rules must be provided with every invocation of this operation.
Now you can use the Virtual Private Network egress configuration in your custom AEM code and configuration.
With the Virtual Private Network enabled, AEM code and configuration can use them to make calls to external services via the VPN. There are two flavors of external calls that AEM treats differently:
HTTP/HTTPS requests from AEM on standard ports (80/443) are allowed by default but they will not use the VPN connection if not configured appropriately as described below.
When creating HTTP/HTTPS connections from AEM, when using VPN, HTTP/HTTPS connections are automatically proxied out of AEM. No additional code or configuration is required to support HTTP/HTTPS connections.
See AEM as a Cloud Service’s Virtual Private Network documentation for the full set of routing rules.
![]() Java™ code example making HTTP/HTTPS connection from AEM as a Cloud Service to an external service using HTTP/HTTPS protocol. |
When creating non-HTTP/HTTPS connections (ex. SQL, SMTP, and so on) from AEM, the connection must be made through a special host name provided by AEM.
Variable name | Use | Java™ code | OSGi configuration |
---|---|---|---|
AEM_PROXY_HOST |
Proxy host for non-HTTP/HTTPS connections | System.getenv("AEM_PROXY_HOST") |
$[env:AEM_PROXY_HOST] |
Connections to external services are then called through the AEM_PROXY_HOST
and the mapped port (portForwards.portOrig
), which AEM then routes to the mapped external hostname (portForwards.name
) and port (portForwards.portDest
).
Proxy host | Proxy port | External host | External port | |
---|---|---|---|---|
AEM_PROXY_HOST |
portForwards.portOrig |
→ | portForwards.name |
portForwards.portDest |
