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 HAQM VPC IP Address Manager (IPAM) integration that allows you to use predictable IP address blocks for your internet-facing ALBs. This feature helps […]

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

HAQM 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 […]

Use VPC IP Address Manager to manage subnet CIDRs

HAQM VPC IP Address Manager (IPAM) is a VPC feature that allows you to plan, track, and monitor IP addresses for your AWS workloads. Until now, VPC IPAM allowed you to allocate CIDR blocks and monitor them at the VPC level. With a recent feature enhancement in VPC IPAM, you can now manage CIDR allocations […]

Using NAT Gateways with multiple-HAQM VPCs at scale

Introduction HAQM Virtual Private Cloud (HAQM VPC) use Network Address Translation (NAT) so resources in private subnets can communicate with resources in the internet, other VPCs, on-premises networks, or even the same VPC using the NAT Gateway’s IP address. HAQM VPC NAT Gateway is managed by AWS and addresses this need while providing redundancy, scalability, […]

NetDevSecOps to modernize AWS networking deployments

NetDevOps orchestrates and automates network changes to shorten the network delivery lifecycle, treats the network as code to allow for version control, and tests changes to make sure of quality and stability. This increased speed helps organizations better serve their customers and compete more effectively in the market. The post NetDevOps: A modern approach to AWS […]

Implementing long-running TCP Connections within VPC networking

Many network appliances define idle connection timeout to terminate connections after an inactivity period. For example, appliances like NAT Gateway, HAQM Virtual Private Cloud (HAQM VPC) Endpoints, and Network Load Balancer (NLB) currently have a fixed idle timeout of 350 seconds. Packets sent after the idle timeout expired aren’t delivered to the destination. Some applications or […]

IP Address Management for AWS Control Tower

For many customers, governing and auditing IP address allocation for at-scale networks is a complex, time-consuming, and potentially error-prone task. This is because application workloads are rapidly migrating to the cloud. Traditionally, network administrators have resorted to using combinations of spreadsheets, home-grown tools, and scripts to track address assignments across multiple accounts, HAQM Virtual Private […]

Introducing IPv6-only subnets and EC2 instances

In June 2021, we announced our continued commitment and innovation towards the enablement of IPv6 on AWS. Today, we take a monumental step forward with the ability to create an IPv6-only architecture on AWS. With this launch, HAQM Virtual Private Cloud (VPC) now allows you to create IPv6-only subnets in your dual-stack VPCs and launch […]

Automated VPC prefix list population for cross-Region and in-Region security group referencing

AWS customers regularly use the ability to reference another security group in the same HAQM Virtual Private Cloud (VPC), or a peered VPC in the same Region, as a dynamic reference. This ability allows customers who have highly ephemeral workloads to adopt the practice of least privilege more easily. We do not currently support security […]
