Customer responsibilities for Azure Spring Apps Standard consumption and dedicated plan in a virtual network
Note
The Basic, Standard, and Enterprise plans will be deprecated starting from mid-March, 2025, with a 3 year retirement period. We recommend transitioning to Azure Container Apps. For more information, see the Azure Spring Apps retirement announcement.
The Standard consumption and dedicated plan will be deprecated starting September 30, 2024, with a complete shutdown after six months. We recommend transitioning to Azure Container Apps. For more information, see Migrate Azure Spring Apps Standard consumption and dedicated plan to Azure Container Apps.

This article describes the customer responsibilities for running an Azure Spring Apps Standard consumption and dedicated plan service instance in a virtual network.
Use Network Security Groups (NSGs) to configure virtual networks to conform to the settings required by Kubernetes.
To control all inbound and outbound traffic for the Azure Container Apps environment, you can use NSGs to lock down a network with more restrictive rules than the default NSG rules.
The following tables describe how to configure a collection of NSG allow rules.
Note
The subnet associated with a Azure Container Apps environment requires a CIDR prefix of /23
or larger.
Protocol | Port | ServiceTag | Description |

UDP | 1194 |
AzureCloud.<region> |
Required for internal Azure Kubernetes Service (AKS) secure connection between underlying nodes and the control plane. Replace <region> with the region where your container app is deployed. |

- If you're running HTTP servers, you might need to add ports
80
and443
. - Adding deny rules for some ports and protocols with lower priority than
65000
may cause service interruption and unexpected behavior.
