What’s new in Azure Firewall
What’s new in Azure Firewall

This post was co-authored by Anitha Adusumilli, Principal Program Manager, Azure Networking. 

Today we are happy to share several key Azure Firewall capabilities as well as update on recent important releases into general availability (GA) and preview.

Multiple public IPs soon to be generally available Availability Zones now generally available SQL FQDN filtering now in preview Azure HDInsight (HDI) FQDN tag now in preview Central management using partner solutions

Azure Firewall is a cloud native firewall-as-a-service offering which enables customers to centrally govern and log all their traffic flows using a DevOps approach. The service supports both application and network level filtering rules and is integrated with the Microsoft Threat Intelligence feed for filtering known malicious IP addresses and domains. Azure Firewall is highly available with built-in auto scaling.

Multiple public IPs soon to be generally available

You can now associate up to 100 public IP addresses with your firewall. This enables the following scenarios:

DNAT – You can translate multiple standard port instances to your backend servers. For example, if you have two public IP addresses, you can translate TCP port 3389 (RDP) for both IP addresses. SNAT – Additional ports are available for outbound SNAT connections, reducing

Announcing the preview of Microsoft Azure Bastion

For many customers around the world, securely connecting from the outside to workloads and virtual machines on private networks can be challenging. Exposing virtual machines to the public Internet to enable connectivity through Remote Desktop Protocol (RDP) and Secure Shell (SSH), increases the perimeter, rendering your critical networks and attached virtual machines more open and harder to manage.

RDP and SSH are both a fundamental approach through which customers connect to their Azure workloads. To connect to their virtual machines, most customers either expose their virtual machines to the public Internet or deploy a bastion host, such as jump-server or jump-boxes.

So today, I’m excited to announce the preview of Azure Bastion.

Azure Bastion is a new managed PaaS service that provides seamless RDP and SSH connectivity to your virtual machines over the Secure Sockets Layer (SSL). This is completed without any exposure of the public IPs on your virtual machines. Azure Bastion provisions directly in your Azure Virtual Network, providing bastion host or jump server as-a-service and integrated connectivity to all virtual machines in your virtual networking using RDP/SSH directly from and through your browser and the Azure portal experience. This can be executed with just two clicks and

Taking advantage of the new Azure Application Gateway V2

We recently released Azure Application Gateway V2 and Web Application Firewall (WAF) V2. These SKUs are named Standard_v2 and WAF_v2 respectively and are fully supported with a 99.95% SLA. The new SKUs offer significant improvements and additional capabilities to customers:

Autoscaling allows elasticity for your application by scaling the application gateway as needed based on your application’s traffic pattern. You no longer need to run application gateway at peak provisioned capacity, thus significantly saving on the cost. Zone redundancy enables your application gateway to survive zonal failures, offering better resilience to your application Static VIP feature ensures that your endpoint address will not change over its lifecycle Header Rewrite allows you to add, remove or update HTTP request and response headers on your application gateway, thus enabling various scenarios such as HSTS support, securing cookies, changing cache controls etc. without the need to touch your application code. Faster provisioning and configuration update time Improved performance for your application gateway helps reduce overall cost

We highly recommend that customers use the V2 SKUs instead of the V1 SKU for new applications/workloads.

Customers who have existing applications behind the V1 SKUs of Application Gateway/WAF should also consider migrating to the V2

Integrating Azure CNI and Calico: A technical deep dive
Integrating Azure CNI and Calico: A technical deep dive

This post was co-authored by Andy Randall, VP of Business Development, Kinvolk Gmbh

We are pleased to share the availability of Calico Network Policies in Azure Kubernetes Service (AKS). Calico policies lets you define filtering rules to control flow of traffic to and from Kubernetes pods. In this blog post, we will explore in more technical detail the engineering work that went into enabling Azure Kubernetes Service to work with a combination of Azure CNI for networking and Calico for network policy.

First, some background. Simplifying somewhat, there are three parts to container networking:

Allocating an IP address to each container as it’s created, this is IP address management or IPAM. Routing the packets between container endpoints, which in turn splits into: Routing from host to host (inter-node routing). Routing within the host between the external network interface and the container, as well as routing between containers on the same host (intra-node routing). Ensuring that packets that should not be allowed are blocked (network policy).

Typically, a single network plug-in technology addresses all these aspects. However, the open API used by Kubernetes Container Network Interface (CNI), actually allows

Rewrite HTTP headers with Azure Application Gateway
Rewrite HTTP headers with Azure Application Gateway

We are pleased to share the capability to rewrite HTTP headers in Azure Application Gateway. With this, you can add, remove, or update HTTP request and response headers while the request and response packets move between the client and backend application. You can also add conditions to ensure that the headers you specify are rewritten only when the conditions are met. The capability also supports several server variables which help store additional information about the requests and responses, thereby enabling you to make powerful rewrite rules.

Figure 1: Application Gateway removing the port information from the X-Forwarded-For header in the request and modifying the Location header in the response.

Rewriting the headers helps you accomplish several important scenarios. Some of the common use cases are mentioned below.

Remove port information from the X-Forwarded-For header

Application gateway inserts X-Forwarded-For header to all requests before it forwards the requests to the backend. The format of this header is a comma-separated list of IP:Port. However, there may be scenarios where the backend applications require the header to contain only the IP addresses. One such scenario is when the backend application is a Content Management System (CMS) because most CMS are not able

Azure Front Door Service is now generally available
Azure Front Door Service is now generally available

Every internet facing web application, whether serving a large audience or a small set of users in a single region, is by default a global application.  Whether you are running a large news website with millions of users across the globe, running a B2B application for managing your sales channels or a local pastry shop in a city – your users are distributed/roaming across multiple locations, or your application demands deployment into multiple locations for high availability or disaster recovery scenarios.  As a global application, your distributed users and/or application deployments place demands on you to maximize performance for your end users and ensure the application is always-on across failures and attacks.

Today I am excited to announce the general availability of Azure Front Door Service (AFD) which we launched in preview last year – a scalable and secure entry point for fast delivery of your global applications. AFD is your one stop solution for your global website/application and provides:
