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

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.

Bye Bye Windows Server 2008R2 It was a good time – Get Extended Support and think about a change

Today Windows Server 2008 (R2) / Windows 7 reaches her End of Live (14.01.20) date and doesn`t receive Security updates anymore.

I think it was a great time with Windows Server 2008. WS2008 launched Hyper-V, one of the most powerful hypervisor on the market and the foundation of today’s Azure infrastructure. With WS2008, the first version of the Server Manager, the pre-release version of Windows Admin Center, was released.

In this article, I will list some of your options to get extended support for available Windows Server 2008 (R2) – but I prefer to discuss new solutions to replace the outdated infrastructure. Use this date to consider a change to move your infrastructure to the same flexible and scalable environment you had when Windows Server 2008 was introduced.

I know the time is to short to demote the existing Windows Server 2008 R2 and migrate the workloads to a newer operating system. But now it’s time to modernize your landscape. See which solutions Microsoft offer to extend the time or to renew the infrastructure.

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.
