Many network appliances define idle connection timeout to terminate connections after an inactivity period. For example, appliances like NAT Gateway, Amazon Virtual Private Cloud (Amazon 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 […]

Introduction With the increasing adoption of IPv6 on AWS, the need to create an easy-to-manage, hierarchical, and scalable IP addressing plan for Amazon Virtual Private Clouds (Amazon VPCs) becomes critical for customers. With IPv4, adding more CIDR blocks to a VPC was driven mainly by the need to increase the address space within a VPC. […]

Introduction: AWS Gateway Load Balancer (GWLB) is an Elastic Load Balancing (ELB) service that allows customers to insert third-party virtual appliances such as firewall, intrusion detection and prevention systems (IDS/IPS), network observability and others, transparently into the traffic path. Application Load Balancer (ALB) and Network Load Balancer (NLB) are reverse proxies and traffic is routed […]

Introduction Amazon Web Services (AWS) customers are continuously increasing the number of applications and workloads they run on AWS, driven by accelerated cloud adoption and environment expansion. An environment can be considered “Hyperscale” once it supports thousands of application endpoints and tens or hundreds of gigabits of traffic per second. Hyperscale environments on AWS favor […]

Traditionally, communication service providers (CSPs) in the telecom industry have used a Virtual Routing and Forwarding (VRF) technique to segregate their data center (DC) networks per each network domains; for examples of domain such as Operation, Administration & Management (OAM), signaling, roaming, and user traffic networks. Each VRF domain in the data center must also […]

In this post, we’ll discuss the considerations, recommendations, and approach for migrating AWS accounts between AWS Organizations from a networking perspective. We’ll explain the behavior of AWS networking resources when AWS accounts are moved between Organizations. We’ll also analyze the behavior from different viewpoints including service availability, management and governance, as well as commercial and operations. […]

Networks have grown larger and more complex with time, but they continue to be the foundation upon which applications and services run. This critical component has demanding requirements to keep up with a high velocity application development world. How can you enable your network to deliver these requirements with confidence? By adopting NetDevOps practices. This […]

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, Amazon Virtual Private Cloud (VPC) now allows you to create IPv6-only subnets in your dual-stack VPCs and launch […]

Network architects need the ability to gain insights into real-time traffic between different resources within their VPCs. Since the announcement of VPC Traffic Mirroring in 2019, the VPC feature has provided this by copying network traffic from elastic networking interfaces (ENIs) on customer’s instances as source, and then sending the traffic to a destination target […]

An update was made on October 15, 2024: With the release of Athena engine version 3, native support for IP address functions is available through the Trino project. This eliminates the need for the Lambda function approach outlined in this blog post. To take advantage of this new enhancement, it is necessary to update the […]
