Customers frequently use on-premises DNS infrastructure to resolve DNS queries for internal domains. In 2018, we announced Amazon Route 53 Resolver endpoints, which enable customers to integrate Route 53 with their on-premises DNS infrastructure for hybrid DNS resolution. In 2023, we improved this integration by providing customers the ability to encrypt DNS queries and responses […]

This post assumes a certain level of technical knowledge, including familiarity with DNS terminology, Wireshark, and Amazon Route 53 Resolver endpoints. Introduction The Domain Name System (DNS) is a critical service underpinning nearly the entire internet. As nearly every application begins with DNS resolution, a highly available and performant DNS architecture is crucial for application […]

In May 2024, Amazon Web Services (AWS) launched a new feature for internet-facing Application Load Balancers. This enhancement allows you to provision an internet-facing Application Load Balancer without needing public IPv4 addresses, enabling clients to connect using only IPv6 addresses. To connect, clients resolve the AAAA DNS records assigned to the Application Load Balancer. The […]

An update was made on April 11th, 2024, outlining deployment procedure. This post guides you through setting up the networking layer for a multi-Region active-active application architecture on AWS using latency-based routing in Amazon Route 53 with Amazon CloudFront to deliver a low-latency, reliable experience for your users. Building active-active architectures using AWS networking services improves […]

Public IPv4 addresses have been a scarce resource going all the way back to 2011, when the Internet Assigned Numbers Authority (IANA) distributed the last block of unallocated public IPv4 addresses. Alongside, the private IPv4 range carved out by RFC1918 has also been too small for large networks and deployments, like containers that consume a […]

Earlier this year, we released technical guidance regarding three advanced design patterns for highly available applications using Amazon CloudFront and Amazon Route 53. In this post, we dive deeper into CloudFront origin failover, Amazon Route 53 DNS failover, and the hybrid origin failover approach to further enhance the availability of your web applications. We also […]

Organizations require methods to restrict access to content to adhere to compliance and regulatory requirements, sanctions, privacy laws, territorial ownership rights, security controls, etc. One way that companies restrict access is by Geo-blocking – restricting access to a website or another piece of content based on a user’s location. A popular method of geo-blocking content is […]

Introduction Customers use multi-region architecture to achieve application resiliency such as Active-Active or Disaster Recovery (DR). Depending on DR strategy, customers may need to have failover from one region to the next. DR strategies are covered off in detail in a prior AWS Blog. DR strategies include either an Active/Passive or Multi-Site Active/Active approaches. Active/Passive […]

As organizations grow, they must often serve geographically dispersed users with low latency, prompting them to have a distributed global infrastructure in the cloud. In this article, we describe how to deploy global API endpoints to reduce latency for end-users while increasing an application’s availability. By using the AWS Global Network and Amazon CloudFront to deploy applications into multiple […]

We’ll start by outlining how AWS services provide reliability using control planes and data planes, then share high-level design principles for creating a failover mechanism. Finally, we’ll explain the features of Route 53 that make your DR approach more effective.
