Introduction In this post, we review advanced global routing scenarios with AWS Cloud WAN and AWS Direct Connect and dive into how you can control routing to build connectivity between AWS and on-premises locations. We also share best practices for optimizing routing in multi-Region hybrid networks and review common high-availability settings and failover scenarios. Customers […]

Many AWS customers use consolidated billing, and often need to allocate costs across their internal business units or accounts. This can be challenging when dealing with services that are shared by all accounts. For general chargebacks, some customers use cost allocation tags for this purpose. However, at the time of writing this post, there is […]

In April 2023, AWS increased several AWS Direct Connect quota limits, as you have asked for increased scale and capacity for hybrid cloud connectivity. With the new limits, you can now create up to four Transit Virtual interfaces (VIFs) per AWS Direct Connect dedicated connection. The maximum number of prefixes has increased to 200 for […]

Motional — a joint venture between Aptiv and Hyundai Motor Group — is developing and commercializing SAE (Society of Automotive Engineers) Level 4 autonomous vehicles (AVs) for autonomous ride-hail and delivery. Motional partners with major ride-hail companies, including Uber, Uber Eats, and Lyft to deploy its AVs on their networks. Motional operates vehicle garages in […]

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), […]

As new AWS Direct Connect locations become available, we recommend customers review their options to make sure they are using the best route to connect to AWS. Many times, moving a connection to a Direct Connect location that is geographically closer to your data centers (DCs) and branch locations can improve network performance, and might […]

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 on-premises environments. We work with many customers to build hybrid networks that connect their on-premises environments to Cloud WAN using AWS Direct Connect. This extends their […]

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 […]
