Exploring Data Transfer Costs for AWS Network Load Balancers

In this post, we explore how Amazon Elastic Compute Cloud (Amazon EC2) data transfer costs apply to the communication between Network Load Balancer (NLB), clients, and targets in multiple scenarios, to help you optimize data transfer costs on Amazon Web Services (AWS). For Classic and Application load balancers, visit our post, Exploring Data Transfer Costs […]

Streamline DNS management for AWS PrivateLink deployment with Amazon Route 53 Profiles

An update was made on August 7, 2025: With the availability of the Amazon Route 53 Profiles and interface VPC endpoint integration, the below design approach can be greatly simplified and is no longer recommended. Instead we recommend to use of this new capability, as outlined in the blog post “Streamlining multi-VPC DNS management with […]

Network latency concepts and best practices for a resilient architecture

Network incidents can occur at times that may impact latency in AWS Regions , Availability Zones (AZs), and individual infrastructure components, such as server hardware. Users can also experience more latency because of the introduction of network appliances in their traffic path. This post explains some of the best practices that allow you to identify […]

How Northwestern Mutual optimized and improved efficiency with Amazon Route 53 Profiles

Managing DNS configurations across multiple Amazon Virtual Private Clouds (Amazon VPCs) and Amazon Web Services (AWS) accounts can be a daunting task for network administrators, especially in complex environments with numerous Private Hosted Zones (PHZs) and Amazon Route 53 Resolver rules. Traditionally, they relied on outbound and inbound Route 53 Resolver endpoints to transport DNS […]
