 1. **Compute Isolation:** Isolated Image Builds perform major portion of image building processing in Azure Container Instances resources in your subscription instead of on AIB's shared platform resources. ACI provides hypervisor isolation for each container group to ensure containers run in isolation without sharing a kernel.
 2. **Network Isolation:**  Isolated Image Builds remove all direct network WinRM/ssh communication between your build VM and Image Builder service. 
-    - If you are provisioning an Image Builder template without your own Virtual Network, then a Public IP Address resource will no more be provisioned in your staging resource group at image build time.
-    - If you are provisioning an Image Builder template with an existing Virtual Network in your subscription, then a Private Link based communication channel will no more be set up between your Build VM and AIB's backend platform resources. Instead, the communication channel is set up between the Azure Container Instance and the Build VM resources - both of which reside in the staging resource group in your subscription.

 3. **Transparency:** AIB is built on HashiCorp [Packer](https://www.packer.io/). Isolated Image Builds executes Packer in the ACI in your subscription, which allows you to inspect the ACI resource and its containers. Similarly, having the entire network communication pipeline in your subscription allows you to inspect all the network resources, their settings, and their allowances.
 4. **Better viewing of live logs:** AIB writes customization logs to a storage account in the staging resource group in your subscription. Isolated Image Builds provides with another way to follow the same logs directly in the Azure portal, which can be done by navigating to Image Builder's container in the ACI resource.
