In multi-Region AWS Cloud WAN deployments, customers deploy centralized architectures for use cases such as traffic inspection, hybrid connectivity (using AWS Transit Gateways and AWS Direct Connect), and internet egress. For internet egress, you may use a single egress VPC per AWS Region or per geography (collection of AWS Regions), for example, Americas (AMER GEO), […]

Introduction HAQM Virtual Private Cloud (HAQM VPC) use Network Address Translation (NAT) so resources in private subnets can communicate with resources in the internet, other VPCs, on-premises networks, or even the same VPC using the NAT Gateway’s IP address. HAQM VPC NAT Gateway is managed by AWS and addresses this need while providing redundancy, scalability, […]

Update: Jan 14, 2025 – AWS launched built-in support for Direct Connect attachments without requiring a TGW. For more information, please see the following launch blog AWS Cloud WAN is a managed wide-area networking (WAN) service for building, managing, and monitoring a unified global network, as well as connecting resources running across your cloud and […]

In this post, we provide recommendations to improve network performance on AWS and hybrid networks. In today’s enterprise networking environment, it is becoming common for customers to have multi-gigabit connectivity to AWS either through AWS Direct Connect or over the Internet. Although network bandwidth is fundamental, several other factors come into play for network performance, […]

Virtual Routing and Forwarding (VRF) is a traditional network feature which uses isolated logical routing domains (route tables/VRFs) to keep network traffic separated within the same physical infrastructure. Customers ask us how to combine the segmentation provided by AWS Cloud WAN and AWS Transit Gateway with VRF isolation when connecting their on-premises networks to AWS. […]

AWS Cloud WAN makes it easy to build and operate wide area networks that connect your data centers and branch offices, as well as your HAQM Virtual Private Clouds (VPCs). With Cloud WAN, you connect to AWS through your choice of local network providers, then use a central dashboard and network policies to create a […]

NetDevOps orchestrates and automates network changes to shorten the network delivery lifecycle, treats the network as code to allow for version control, and tests changes to make sure of quality and stability. This increased speed helps organizations better serve their customers and compete more effectively in the market. The post NetDevOps: A modern approach to AWS […]

This post presents recommendations and best practices when migrating your existing VPCs from HAQM Virtual Private Cloud (VPC) Peering to AWS Transit Gateway. It includes a migration walkthrough and considerations that you can address to improve your odds of a seamless migration. This post also details common networking testing and bench-marking tools such as iPerf […]

There are many things to consider when connecting your HAQM Virtual Private Clouds (HAQM VPCs) to third-party applications running in data centers outside AWS. You need connections that are secure and scalable, especially when the third-party vendor uses a multi-tenant architecture. With multi-tenant services, where they have many of their customers sharing the same system, […]

Introduction This blog will describe the recommended migration approach for migrating existing hybrid connectivity architectures with sub 1 Gbps AWS Direct Connect hosted connections to AWS Transit Gateway. It will provide you with a target architecture along with step-by-step prescriptive guidance on how to migrate from your existing state. Key benefits you can derive from […]
