Rules Engine for Azure Front Door and Azure CDN is now generally available

Today we are announcing the general availability of the Rules Engine feature on both Azure Front Door and Azure Content Delivery Network (CDN). Rules Engine places the specific routing needs of your customers at the forefront of Azure’s global application delivery services, giving you more control in how you define and enforce what content gets served from where. Both services offer customers the ability to deliver content fast and securely using Azure’s best-in-class network. We have learned a lot from our customers during the preview and look forward to sharing the latest updates going into general availability.

How Rules Engine works

We recently talked about how we are building and evolving the architecture and design of Azure Front Door Rules Engine. The Rules Engine implementation for Content Delivery Network follows a similar design. However, rather than creating groups of rules in Rules Engine Configurations, all rules are created and applied to each Content Delivery Network endpoint. Content Delivery Network Rules Engine also boasts the concept of a global rule which acts as a default rule for each endpoint that always triggers its action.

Use Azure Firewall for secure and cost-effective Windows Virtual Desktop protection

This post was co-authored by Pavithra Thiruvengadam, Program Manager, Windows Virtual Desktop

Work from home policies require many IT organizations to address fundamental changes in capacity, network, security, and governance. Many employees aren’t protected by the layered security policies associated with on-premises services while working from home. Virtual desktop infrastructure (VDI) deployments on Azure can help organizations rapidly respond to this changing environment.  However, you need a way to protect inbound or outbound internet access to and from these VDI deployments.

Windows Virtual Desktop is a comprehensive desktop and application virtualization service running in Azure. It’s the only VDI that delivers simplified management, multi-session Windows 10, and optimizations for Office 365. You can deploy and scale your Windows desktops and apps on Azure in minutes and get built-in security and compliance features. In this post, we explore how to use Azure Firewall for secure and cost-effective Windows Virtual Desktop protection.

Windows Virtual Desktop components

The Windows Virtual Desktop service is delivered in a shared responsibility model:

Customer-managed RD clients connect to Windows desktops and applications from their favorite client device from anywhere on the internet. Microsoft-managed Azure service handles connections between RD clients and Windows Virtual Machines in Azure

How Azure VPN helps organizations scale remote work
How Azure VPN helps organizations scale remote work

In the weeks and months we have all been grappling with the global pandemic, there’s no doubt about the impact it has had on the lives of people everywhere. A shift to remote work is one of the widespread effects of the global pandemic, and we heard from organizations around the world who are looking for ways to enable more of their employees to work remotely for their safety and that of the community. With this shift, we’re working to address common infrastructure challenges businesses face when helping employees stay connected at scale.

Common challenges for businesses expanding secure, remote access

One of the major challenges while setting up remote access is providing workers/employees access to key internal resources, which may reside on-premises or Azure, for example, healthcare or government organizations who have sensitive patient or tax information in on-premises datacenters and other sensitive information in Azure.

Another challenge that the businesses around the world now face is how to quickly scale an existing VPN setup, which is typically targeted at a small portion of an organization’s workforce, to now accommodate all or most workers. Even within Microsoft, we’ve seen our typical remote access at 50,000+ employee spike to as

Azure Container Registry Private Link support preview for virtual networks

Azure Container Registry announces preview support for Azure Private Link, a means to limit network traffic of resources within the Azure network.

With Private Link, the registry endpoints are assigned private IP addresses, routing traffic within a customer-defined virtual network. Private network support has been one of the top customer asks, allowing customers to benefit from the Azure management of their registry while benefiting from tightly controlled network ingress and egress.
  

Private Links are available across a wide range of Azure resources with more coming soon, allowing a wide range of container workloads with the security of a private virtual network.

Private Endpoints and Public Endpoints

Private Link provides private endpoints to be available through private IPs. In the above case, the contoso.azurecr.io registry has a private IP of 10.0.0.6 which is only available to resources in contoso-aks-eastus-vnet. This allows the resources in this VNet to securely communicate. The other resources may be restricted to resources only within the VNet.

At the same time, the public endpoint for the contoso.azurecr.io registry may still be public for the development team. In a coming release, Azure Container Registry (ACR) Private Link will support disabling the public endpoint, limiting access to

ExpressRoute Global Reach: Building your own cloud-based global backbone

Connectivity has gone through a fundamental shift as more workloads and services have moved to the Cloud. Traditional enterprise Wide Area Networks (WAN) have been fixed in nature, without the ability to dynamically scale to meet modern customer demands. For customers seeking to increasingly apply a cloud-first approach as the basis for their app and networking strategy, hybrid cloud enables applications and services to be deployed cross-premises as a fully connected and seamless architecture. The connectivity across premises is moving to utilize a more cloud-first model, with services offered by global hyper-scale networks.
