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 Amazon 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 Amazon 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 Amazon Virtual Private Clouds (Amazon 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 […]

Introduction Since the launch of AWS Transit Gateway, customers have been asking to use transit virtual interface (Transit VIF) on sub 1 Gbps AWS Direct Connect hosted connections. In this post, we describe how to migrate an existing environment that uses sub 1Gbps Direct Connect hosted connections, Transit Gateway, and transit VPC for hybrid connectivity. […]

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, […]

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 […]
