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.

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 […]

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, […]

As enterprises move to the Cloud, having a reliable network connection to their on-premises data centers is fundamental. In this post, I show how to monitor your AWS Direct Connect links and initiate remediation (including automatic failover) when degradation in end-to-end path quality (packet loss, high latency) is detected. Multiple Direct Connect links at separate […]

SiteLink, a new feature of AWS Direct Connect (DX), makes it easy to send data from one Direct Connect location to another, bypassing AWS Regions. Once you have made connections at two or more Direct Connect locations, you can turn on (or off) the SiteLink feature on Private/Transit VIFs and in minutes, a global, reliable, […]

SiteLink, a new feature of AWS Direct Connect (DX), makes it easy to send data from one Direct Connect location to another, bypassing AWS Regions. If you recall, Direct Connect is a cloud service that links your network to AWS, bypassing the internet to deliver more consistent, lower-latency performance. Prior to SiteLink, it was not […]

Introduction This blog post is a continuation of Introduction to Network Transformation on AWS – Part 1. To recap, as your organization begins to embrace cloud, you extend your network to AWS using a hybrid connectivity architecture. When we work with customers, we see that their network traffic patterns have been changing as more applications […]

Many AWS customers like to use their existing Software Defined Wide Area Network (SD-WAN) devices when connecting their on-premises networks to an AWS Transit Gateway. When doing this, a large number of prefixes must be advertised to and from AWS Transit Gateway. In this post, we show how to use the Transit Gateway Connect feature […]
