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 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 […]

AWS now supports IPv6 for AWS PrivateLink services and endpoints. PrivateLink support for IPv6 expedites IPv6 adoption by decoupling the service consumer and service provider IP protocol version. Even if a service provider has not started to support IPv6 for all their back-end services, service consumers can use IPv6 within their VPCs to access the […]

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 […]

Amazon CloudFront provides an easy and cost-effective way to distribute content with low latency and high data transfer speeds using a worldwide network of edge locations. To enable requests from CloudFront to access your origins (the source of your content, for example, Amazon Elastic Compute Cloud (Amazon EC2) instances, the security policies on your origin […]

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 […]

Large enterprises often deploy workloads on Amazon Web Services (AWS) using multiple accounts. This helps isolate workloads, manage permissions more easily, and simplifies cost allocation. However, managing a multi-account environment can make your network topology more complex and requires additional monitoring and automation. At Repsol, a global multi-energy company present throughout the entire value chain, […]

In this blog, you will learn how to use the Lambda Function URL feature to define a AWS Lambda Function as origin for Amazon CloudFront. Lambda Function URL capability provides a dedicated HTTPS endpoint for your Lambda function deployed in an AWS Region. Function URLs are a great fit for use cases where you must […]

Introduction Amazon CloudFront has recently announced a new feature, Server Timing headers, which provides detailed performance information, such as whether content was served from cache when a request was received, how the request was routed to the CloudFront edge location, and how much time elapsed during each stage of the connection and response process. Server […]

Many organizations need to review or audit networking information within AWS environments that contain multiple AWS accounts. At scale, questions such as “which accounts have Internet access enabled?”, “which account owns the Elastic IP 198.51.100.101?” and, “what are the IP addresses of my NAT gateways?” can be challenging to answer. Traditionally, within an individual account, […]
