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 […]

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 […]

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.

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 […]
