Everyone wants the same thing: consistent, resilient DNS services that \u201cjust work\u201d everywhere. But when you start layering in multi-cloud topologies, global reach and the need for fast failover, Anycast DNS quickly shifts from \u201cnice to have\u201d to \u201chard to manage.\u201d <\/p>\n<p>That\u2019s where this story begins. In this blog, we\u2019ll walk through how Infoblox Universal DDI\u2122 and NIOS-X can be deployed natively in AWS, integrated with Cloud WAN and extended with Anycast DNS to provide global reachability. The magic is in combining Infoblox\u2019s centralized management and automation with AWS\u2019s global networking fabric so you can onboard apps faster, reduce operational overhead and deliver a DNS fabric that\u2019s both highly available and cloud ready. <\/p>\n<p>The lab we built demonstrates a practical design with two AWS regions, Frankfurt and Paris. Each region has Shared Services and Production virtual private clouds (VPCs), with Infoblox NIOS-X appliances delivering Anycast DNS. AWS Cloud WAN ties the regions together, optimizing routing and ensuring DNS requests seamlessly fail over when needed. <\/p>\n<p><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/blogs.infoblox.com\/wp-content\/uploads\/delivering-anycast-dns-in-aws-with-infoblox-universal-ddi-figure-1-scaled.jpeg\" alt=\"Figure 1.

These appliances act as the DNS engines for the environment and are centrally managed through the Universal DDI portal. Deployment leverages standard AWS EC2 workflows together with Infoblox join tokens for seamless onboarding. <\/p>\n<p>Deployment steps: <\/p>\n<ol>\n<li>Launch NIOS-X instances in each target region using the Infoblox-provided AMI from the AWS Marketplace.<\/li>\n<li>Apply join tokens during instance initialization so that appliances automatically register with the Universal DDI portal. <\/li>\n<li>Validate onboarding by confirming that the new NIOS-X instances appear under <em>Configure \u2192 Servers<\/em> in the Universal DDI portal.<\/li>\n<\/ol>\n<p>While this blog keeps the focus on architecture, the lab that follows goes further. There we\u2019ll show how the same deployment workflow can be integrated into a continuous integration (CI)\/continuous delivery (CD) pipeline so that NIOS-X appliances can be spun up, registered and configured automatically as part of your infrastructure-as-code process.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/blogs.infoblox.com\/wp-content\/uploads\/delivering-anycast-dns-in-aws-with-infoblox-universal-ddi-figure-2.png\" alt=\"Figure 2.

Universal DDI portal showing NIOS-X appliances registered and online (<em>Configure \u2192 Servers<\/em>) <\/p>\n<p><strong>Why This Matters:<\/strong> This automated onboarding workflow eliminates manual registration steps and ensures new appliances are consistently visible in Universal DDI across regions, reducing deployment time and human error. <\/p>\n<h3>AWS Infrastructure Setup<\/h3>\n<p>In each AWS region, we provisioned two distinct VPCs: <\/p>\n<ul>\n<li><strong>Shared Services VPC<\/strong> hosting Infoblox NIOS-X appliances and other foundational infrastructure services.<\/li>\n<li><strong>Production VPC<\/strong> hosting the application workloads that consume DNS and other shared services.<\/li>\n<\/ul>\n<p>This separation is not new. It\u2019s a classic networking design principle. In the data center, we always carved out a shared infrastructure domain: DNS, DHCP, Active Directory, logging, PKI, monitoring and other core services ran there, decoupled from individual app environments. Connectivity was enforced through virtual routing and forwarding (VRF) separation and route leaking, ensuring reachability while keeping lifecycles cleanly isolated. <\/p>\n<p>In the cloud, the same logic applies, only the mechanics change. Instead of VRFs and firewalls, you use VPCs, peering, Transit Gateway, Cloud WAN and security constructs provided by the cloud service provider (CSP). The architectural pattern stays the same: shared infrastructure delivers consistency while application environments consume those services over well-defined, secure pathways. <\/p>\n<p>As networking architects, we need to recognize that the move to cloud doesn\u2019t eliminate these design rules, it just translates them into new constructs. And at the global level, AWS Cloud WAN stitches those shared infrastructures together, providing the backbone that makes services like Anycast DNS available everywhere. <\/p>\n<p><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/blogs.infoblox.com\/wp-content\/uploads\/delivering-anycast-dns-in-aws-with-infoblox-universal-ddi-figure-3.png\" alt=\"Figure 3.

Create core network and select regions\/edge\/segments <\/p>\n<p><strong>Why This Matters:<\/strong> Defining edge locations and segments early provides a structured backbone that scales across multiple regions and simplifies traffic separation.<\/p>\n<h3>Attaching VPCs and Connect Attachments<\/h3>\n<p>With the Cloud WAN backbone in place, the next step is to attach the regional resources so that traffic can actually flow across the global fabric.

Troubleshooting is more straightforward, since routes exchanged over Cloud WAN are visible as native BGP sessions without additional encapsulation layers. The result is a cleaner design that\u2019s easier to scale and operate. <\/p>\n<p><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/blogs.infoblox.com\/wp-content\/uploads\/delivering-anycast-dns-in-aws-with-infoblox-universal-ddi-figure-5-1.png\" alt=\"Figure 5.

By integrating with AWS Cloud WAN, enterprises gain a single policy-driven backbone that makes DNS highly available, globally reachable and easier to operate at scale. <\/p>\n<p>What you get is more than just DNS resolution\u2014it is a cloud-native architecture that aligns with enterprise requirements for agility, security and reach while preserving the design principles you already know from on-prem networking. <\/p>\n<p>And this is only the beginning. The hands-on lab that follows goes further, showing how to speed up failover beyond default BGP timers, how to use Lambda functions to react to routing events and even how to tie these deployments into a CI\/CD pipeline for full automation.<\/p>\n<h3>Try It Yourself<\/h3>\n<p>To help you get started quickly, I\u2019ve published the complete Terraform code used to automate the setup. You can find it in the <a href=\"https:\/\/github.com\/iracic82\/CloudWAN\" target=\"_blank\"><strong>CloudWAN Terraform repository<\/strong><\/a>.<\/p>\n<h3>Part Two: Anycast on Azure<\/h3>\n<p>We\u2019re just getting started. In part two of this series, we explore how Infoblox Universal DDI and Anycast DNS can be deployed in Microsoft Azure using vWAN. The same principles apply, but the mechanics differ, and we dive into how Cloud WAN concepts translate into the Azure ecosystem. <\/p>\n<p><a href=\"https:\/\/www.infoblox.com\/blog\/company\/delivering-anycast-dns-in-microsoft-azure-with-infoblox-universal-ddi-and-virtual-wan\/\"><strong>Delivering Anycast DNS in Azure with Universal DDI and Virtual WAN<\/strong><\/a> <\/p>\n<style>\n.code-format {\n\tfont-family: 'Courier New';\n}\n.image-caption {\n    font-size: 12px;\n}\n.list-spacing li{margin-bottom:20px}\nol.list-spacing > li::marker {\n    font-weight: 700;\n}\n.entry-content ul.list-spacing ul > li {\n    list-style-type: square;\n}\n<\/style>\n<p><script>\njQuery('.single h1').html('Delivering Anycast DNS in AWS with <span class=\"gradient\">Infoblox Universal DDI\u2122<\/span> and <span class=\"gradient\">AWS Cloud WAN<\/span>');\n<\/script><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Introduction Over the past few months, in conversations I\u2019ve had with enterprises running workloads across multiple regions and hybrid clouds, one theme kept coming up: DNS keeps biting them.
