This is a second video on Azure Private Endpoints and DNS. Previously, we reviewed options for DNS name resolution with Private Endpoint that included a forward lookup zone for the privatelink.file.windows.core.net zone. However, that option required manually adding hosts to the DNS zone. This video reviews a hub-and-spoke configuration leveraging a forwarder server in Azure and conditional forwarding in Windows DNS. Although slightly more complicated, this option does not require manually adding hosts to the DNS lookup zone.Continue reading “Private Endpoints and DNS Part Deux: Azure Private DNS Zones”
Azure services are publicly available over the internet by default. That works for many services, but sometimes we need to limit access to internal networks only. Private Endpoints provide a local, internal connection to resources in Azure. It does this by adding a virtual NIC to a subnet. From there, the NIC gets a private IP address where it can be accessed from the internal network. This video goes over the configuration options to create a new storage account with an Azure File Share Private Endpoint as well as update an existing storage account with a private endpoint.
Private Endpoints in Azure provide a secure way to access resources over the private, internal network. But the options for configuring DNS for Private Endpoints is not as straight forward. This video goes over the options available for DNS with Private Endpoints. We start by crating a storage account with a Private Endpoint, the review the default DNS configuration. We look at The WireServer and how it can be used with a Conditional Forwarder as well as using Forward Lookup Zones for name resolution.Continue reading “Private Endpoints and DNS in Azure”
I’ve been sitting on this topic for a while. I typically like to pass along information that helps people better understand Azure and other Microsoft products absent of my option. However, this post is slightly opinionated, an opinion that was formulated after seeing problems users ran into while trying to use Azure AD as a replacement for Windows AD.Continue reading “Don’t Use Azure AD Domain Services to Replace Windows Domain Controllers”
This video goes over two Azure IP addresses used for Azure VM’s. The WireServer IP of 184.108.40.206 and the Azure Instance Metadata Service (IMDS) IP address 169.254.169.254. In the video, I go over what each is used for and then give a demonstration on using the WireServer IP address to query DNS. After that, I use the IMDS REST Endpoint to pull metadata including the Azure environment and scheduled events.Continue reading “Two Azure IP Addresses You Need to Know About”
Azure Files SMB Access with Windows AD allows you to access file shares in Azure with NTFS access control. By default, that access won’t extend to an on-prem network over VPN or Express Route. This video shows how to extend access to an Azure Files share with Windows AD to an on-premises network using Private Endpoints.Continue reading “Azure Files SMB Access On-premises with Private Endpoints”
This video goes over two ways of restricting access to Microsoft Azures PaaS services; Service Endpoints and Private Endpoints. Both are used to restrict access to PaaS serviced, but work differently. The video gives an overview if the differences and then does a walkthrough of deploying Service Endpoints and Private Endpoints using an Azure Storage account as an example.Continue reading “Azure Virtual Networking Service Endpoints and Private Endpoints”
Azure Traffic Manager is a global DNS service hosted in Azure. It extends the functionality of DNS beyond simple name to IP resolution, adding load balancing and advanced resolution features such as geo-fencing, weighted priority, performance, and source IP based name resolution.
Just as important to what it is, is what it is not. It is not an IP based Global Load Balancer. Traffic Manager does not handle IP session data, BGP or any other routing protocols. It is only an External DNS solution, it won’t work as an internal DNS solution. Continue reading “Azure Traffic Manager”
