Migrating SD-WAN Appliances to AWS Transit Gateway Connect

Introduction Since its launch in 2020, AWS Transit Gateway Connect has provided a native way for you to connect third-party SD-WAN appliances to an AWS Transit Gateway. Connect attachments use Generic Routing Encapsulation (GRE) tunnels and Border Gateway Protocol (BGP) to exchange routes between the Transit Gateway and an appliance. Prior to Transit Gateway Connect, […]

Centralizing outbound Internet traffic for dual stack IPv4 and IPv6 VPCs

Organizations have been adopting IPv6 in their IPv4 environments to solve IP address exhaustion or meet compliance requirements. Since IPv6 isn’t backward compatible with IPv4, several mechanisms can facilitate communication between hosts that support one or both protocols. One common way is by using dual stack deployments. For architectures where dual stack deployments aren’t the […]

Learn how LambdaTest transformed its global hybrid network using AWS

LambdaTest, a leading omnichannel test orchestration and execution cloud platform was looking to scale their multi-Region and hybrid networks. LambdaTest’s existing hybrid global network used AWS Site-to-Site VPN to connect their locations and Amazon Virtual Private Clouds (VPCs) across multiple AWS Regions. LambdaTest is growing rapidly, helping over 2 million developers run over 500 million […]

How to use AWS Network Manager to visualize Transit Gateways across multiple accounts in the AWS Organization

When you migrate or build a new applications in AWS, you must connect multiple Amazon Virtual Private Clouds (Amazon VPCs) spread across different accounts and your on-premises systems with these VPCs. AWS Transit Gateway is one of the most popular and commonly used services in these scenarios. When you want communication/isolation between VPCs, and they also […]

Achieving traffic segmentation in multi-AWS Region environments using AWS Transit Gateway and AWS Cloud WAN

In June 2022, we announced AWS Cloud WAN in general availability, a managed wide area networking (WAN) service that makes it easy for you to build, manage, and monitor a global network connecting your resources across your AWS Regions and on-premises environments. With Cloud WAN, you have a central place to create and manage your […]

Designing hyperscale Amazon VPC networks

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 […]

Design patterns for interconnecting a telco data center to an Amazon VPC

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 […]

Migrating accounts between AWS Organizations from a network perspective

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. […]

Introducing VPC Flow Logs for AWS Transit Gateway

Since the launch of Amazon Virtual Private Cloud (Amazon VPC) Flow Logs in 2015, customers have utilized VPC Flow Logs to gain better visibility of network traffic patterns on AWS by providing network telemetry data regarding the IP traffic flowing to and from ENIs within a given VPC. As customers’ networks grew, customers began utilizing […]

AWS Cloud WAN and AWS Transit Gateway migration and interoperability patterns

Introduction At AWS re:Invent 2021, we launched a public preview of AWS Cloud WAN, a managed service for creating a global network using AWS global network infrastructure. Cloud WAN makes it easy to build and operate global wide area networks (WAN) to connect your data centers, branch offices, and Amazon Virtual Private Clouds (VPCs). Cloud […]
