Introduction Amazon EC2 provides instance-level metrics that measure CPU, disk, and network performance. These metrics include bytes and packets in/out and collected by default and can be viewed in Amazon CloudWatch. Amazon EC2 has recently announced additional high-resolution instance level network performance metrics for Elastic Network Adapter (ENA). With these new metrics you can gain […]

This post guides you through setting up the networking layer for a multi-Region active-active application architecture on AWS using latency-based routing in Amazon Route 53 with Amazon CloudFront to deliver a low-latency, reliable experience for your users. Building active-active architectures using AWS networking services improves your application resiliency and performance. However, there can be cost and […]

Less than three years ago, we announced the 200th Point of Presence for Amazon CloudFront. Since then, we’ve continued to launch more Points of Presence to support more customers and provide them with enhanced content delivery performance. Today, CloudFront has over 400 Points of Presence in 90 cities and across 47 different countries. The expansion of our network […]

When I meet with customers and discuss AWS Gateway Load Balancer (GWLB), I often get asked for suggestions regarding integrating it with their existing Linux appliances. GWLB utilizes GENEVE encapsulation with some important custom metadata, which doesn’t natively work with either Linux or Linux’s GENEVE module (which is designed only for Ethernet (Layer 2) packets, […]

One of the most common ways that customers connect securely to AWS from on premises is by using the AWS Site-to-Site VPN managed IPSec VPN solution. One key benefit our customers look for when using the service is not having to manage 3rd-party or custom VPN solutions built using EC2 instances. The native service is […]

AWS Client VPN is a fully-managed, client-based Virtual Private Network (VPN) service used by your remote workforce to securely access resources within AWS and your on-premises network. It’s an elastic service that automatically scales up or down based on demand. In addition to the free, AWS-provided VPN client, you can also use a common Open […]

A common situation we see in customer networks is when there are resources with overlapping IP address ranges that must communicate with each other. Frequently this occurs when companies are acquired and have used the same private (RFC1918) address ranges. However, it can also occur when a service provider with a unique IP range must […]

In part one of our series on IPv6 for AWS and hybrid network architectures, we explored some of the most common dual stack designs: dual stack Amazon Virtual Private Cloud (Amazon VPC) and Amazon Elastic Compute Cloud (Amazon EC2) instances, Internet connectivity, Internet-facing Network Load Balancer and Application Load Balancer deployments, as well as VPC […]

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 […]

Amazon Route 53 is a highly available and scalable cloud Domain Name System (DNS) web service. Route 53 provides you with the ability to manage traffic to your public domains globally through a variety of routing types, including latency-based routing, geolocation, geoproximity, and weighted routing – all of which can be combined with DNS failover […]
