Simplify ALB’s public IP address assignment with VPC IPAM

Application Load Balancer (ALB) operates at layer-7 of the OSI model and allows you to load balance HTTP and HTTPS requests to its backend targets. In March 2025, we launched ALB and Amazon VPC IP Address Manager (IPAM) integration that allows you to use predictable IP address blocks for your internet-facing ALBs. This feature helps […]

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 […]

Encrypt DNS queries using DNS-over-HTTPS (DoH) with Amazon Route 53 Resolver Endpoints

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 […]

Demystifying AWS Data Transfer services to build secure and reliable applications

For cloud users, evaluating data transfer services can be complex, especially when the internal engineering that manages security and delivers high availability and low latency is often abstracted. We are starting a series of posts intended to demystify AWS Data Transfer services and to clarify exactly what Amazon Web Services (AWS) users get when they […]

Using cross-zone load balancing with zonal shift

Today, we’re announcing Amazon Application Recovery Controller (ARC) zonal shift support for Application Load Balancers (ALB) with cross-zone load balancing enabled. This complements the support for Network Load Balancers (NLB) using cross-zone load balancing we announced previously. Now you can use zonal shift with both NLBs and ALBs, with or without cross-zone load balancing configured, […]

Migrate Amazon ECS service communication to Amazon VPC Lattice

Advanced L7 routing, authentication and authorization using IAM Policies, and deep observability are key capabilities offered by Amazon VPC Lattice. With VPC Lattice now integrated into Amazon Elastic Container Service (Amazon ECS), you can easily migrate service-to-service communication from using internal Elastic Load Balancing (ELB) to VPC Lattice. This allows you to benefit from VPC Lattice […]

Estimate AWS networking costs with a self-hosted calculator

Amazon Web Services (AWS) offers a wide choice of networking services. While these services enable AWS to meet more customer needs around networking, that variety increases the number of available options to consider in making architectural decisions when designing AWS and hybrid networking infrastructure. Cost is one of the main factors that drive architectural decisions […]

Networking best practices for generative AI on AWS

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 […]

Satellite communication on AWS: Thales cloudifies in-flight WiFi service

Amazon Web Services (AWS) has found widespread adoption in the satellite communication and aerospace sectors, serving not only as a platform for modernizing their overall IT infrastructure but also for delivering network connectivity solutions. One prominent example showcases how a leading satellite and aerospace company, Thales Avionics, used AWS to build a virtual data center […]

Introducing VPC Flow Logs for Elastic Container Services

Introduction Amazon Virtual Private Cloud (VPC) is the foundational networking construct used by customers to deploy workloads on AWS. To examine VPC traffic and gain insights into communication patterns, customers collect and analyze VPC Flow Logs, leveraging the capabilities and features AWS has continuously added since 2015. You can get started with Flow Logs by […]
