Improving security and performance with additional DNS resource record types in Amazon Route 53

DNS is a key component of modern computing, a phone book for IP addresses. It is distinct from other protocols in the application stack. Because it is queried early in the request by a client, DNS is well suited to relay application-specific information back to a client as early as possible. This additional data can […]

Migrating your multi-account DNS environment to Amazon Route 53 Profiles

Introduction Large enterprises have a centralized networking team for configuring and managing baseline DNS settings across a multi-account, multi-VPC environment. Amazon Route 53 Profiles provides an ability to simplify management of DNS configuration across multiple VPCs and AWS accounts. Before this feature, users needed to perform the association of Private Hosted Zones (PHZ) and Route […]

Use AWS Global Accelerator to improve application performance

In the dynamic landscape of web applications and APIs, ensuring fast, reliable, and secure access for all your customers is crucial. With traditional implementations, though, users of global applications often face latency and reliability challenges because of delays and uneven performance due to the complexity of the global internet infrastructure. AWS Global Accelerator enables you […]

Active Directory Domain Services integration with Amazon Route 53

Anyone who has worked with Microsoft Active Directory Domain Services (AD DS) and domain-joined workloads in the past likely knows how critical proper DNS resolution is to healthy operations. Even if you haven’t worked with AD DS workloads, if you are reading this post, you have likely heard of some outage that was caused by […]

How to achieve DNS high availability with Route 53 Resolver endpoints

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 […]

DNS best practices for Amazon Route 53

Most web services rely on DNS to resolve names to IP addresses and sometimes other pieces of information. Amazon Route 53 provides highly available and scalable recursive DNS resolution, domain registration, and authoritative DNS-hosted zones that include health check capabilities and a broad array of routing capabilities. When using Amazon Route 53, you can scale […]

Introducing dual-stack without public IPv4 Application Load Balancer

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 […]

Scaling strategies for Elastic Load Balancing

Elastic Load Balancing (ELB) offers four types of load balancers, all featuring high availability, automatic scaling, and robust security support for your applications: Application Load Balancer (ALB), Network Load Balancer (NLB), Gateway Load Balancer (GWLB), and Classic Load Balancer (CLB). ELB automatically scales up and down, and scales in and out in response to traffic […]

Using Amazon Route 53 Profiles for scalable multi-account AWS environments

Amazon Web Services (AWS) customers implement multi-account strategies so that multiple teams can deploy workloads in separate organizational units (OUs) and AWS accounts. Cloud administrators are using this practice through offerings such as AWS Control Tower and AWS Organizations. These services help them get things done using individual accounts while maintaining centralized control for governance […]
