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 […]

In today’s interconnected world, businesses of all sizes rely on secure and efficient network connectivity to operate seamlessly across multiple locations. Amazon Web Services (AWS) Site-to-Site Virtual Private Networks (Site-to-Site VPN) offer a reliable way to extend a private network across public infrastructure such as the internet, enabling organizations to securely connect their offices, data centers, and Amazon Virtual […]

Introduction As generative artificial intelligence (generative AI) continues to evolve, the demand for more powerful and efficient computing resources grows, along with the need to manage exponentially increasing amounts of data. Datasets used for training generative AI models are typically measured in terabytes (TB), orders of magnitude bigger than traditional machine learning (ML) datasets whose […]

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 this blog post, we present an augmented approach of managing AWS Cloud WAN segments in a secure, scalable, and on-demand way. When your organization increases the number of AWS accounts and AWS Regions in use, operational and security complexities related with admitting new user-created virtual private clouds (Amazon VPCs) to the network also increase—from […]

When a load balancer or proxy cannot preserve the client’s original IP address, it may rewrite the IP address or use its own IP address for routing purposes. In this scenario, common practices such as inserting the original IP address into the request headers (for example, X-Forwarded-For) or utilizing Proxy protocol are widely used to […]

While website performance issues are a common occurrence, pinpointing their root causes can be a challenging task. In this post, you will learn how to simplify the performance troubleshooting process by unlocking the potential of the Server-Timing header. This header allows backend components to communicate timing metrics and other insights relevant to performance monitoring in […]
