Connect and Secure Azure PaaS services to Virtual Networks with Private Link

2 Comments

Azure allows to use IaaS and PaaS solution together over the same network. But all Azure PaaS services using a public interface for connection. When configure the PaaS firewall to allow traffic only from internal VNETs the public interface still exists. With Azure Private Link there is a new service to disable the public interface and add a private endpoint to secure connect to PaaS from your own VNET.

When configuring the internal service Firewall to block all traffic from outside the VNET, the Firewall make a mapping from internal VNET traffic to the Public IP and block all other IP- Adress ranges – and here comes the new Azure Service Private Link into play. This blog post will cover how Private Link works and how to configure this service for your environment including own DNS solution to get a complete private based Azure VNET.

Update 2 on 26/04/2021

I updated the article based on the latest information around Azure Bastion. One big announcement is the support for peered VNETs for Azure Bastion – this is also integrated in this article. Please feel free to share and comment 🙂

Azure Bastion is a new service to reaches Azure VMs in a secure way without needing a Jump host in the same VNET or to publish an Public IP for a VM. Many customers using Public IPs to reach VMs (Windows and Linux) in Test and Dev environment. Please avoid managing Azure VMs over a Public IP, this is unsecure – use Azure Bastion.

Azure Bastion is in public preview since end of June 2019. Azure Bastion is General Available (since Microsoft Ignite 2019) and many limitations are gone. This article will short introduce the service, the new features and how easy is it to enroll the service in the environment to reach Azure VMs (Windows or Linux) over a secure way.
