Using the AWS CDK and AWS Transit Gateway Inter-Region peering to build a global network

An Amazon VPC is a logically isolated section of the AWS cloud. Some of our largest enterprise customers have global networks containing VPCs that need to communicate across different AWS Regions, even across different AWS accounts. While this can appear like a cumbersome and complex task, with AWS Transit Gateway Inter-Region peering, it can be […]

Using AWS Client VPN to scale your work from home capacity

Using AWS Client VPN to scale your work from home capacity

Traditional on-premises VPN services are fixed in capacity and difficult to scale up, or down, in a rapid and on-demand fashion. Hardware constraints, licensing, and bandwidth can all be factors that prevent traditional client VPN services from scaling to meet the needs of a rapidly growing mobile workforce. Fortunately, the elasticity of cloud and pay-as-you-go […]

Building an egress VPC with AWS Transit Gateway and the AWS CDK

Introduction With the introduction of AWS Transit Gateway, it is easier for customers to manage connectivity between many VPCs. Further simplification can be achieved by routing all outbound traffic through one shared egress VPC. This allows re-use of NAT Gateways and can improve overall network design and operational efficiency. This ‘egress VPC’ design pattern is […]

Scaling VPN throughput using AWS transit gateway

Scaling VPN throughput using AWS Transit Gateway

A virtual private network (VPN) is one of the most common ways that customers connect securely to the AWS Cloud from on-premises or data center environments. Customers establish VPN connectivity to AWS using AWS managed VPN solutions like AWS Site-to-Site VPN, transit gateways, or partner solutions running on Amazon EC2. In this post, we demonstrate […]

Securing VPCs Egress using IDS/IPS leveraging Transit Gateway

In a typical enterprise network, customers have VPCs across multiple accounts within an AWS Region to segment workloads. This segmentation can take different forms and depends on the company structure, security policy, business functions, and model. The drivers of the segmentation can vary. For example, segmentation could be driven by security and regulatory requirements, costs, […]

Automating AWS Transit Gateway attachments to a transit gateway in a central account

As IT environments grow, they can become more complex, with additional accounts, VPCs, and the networking between them. AWS Transit Gateway is a service that addresses networking complexity by building a hub-and-spoke network to simplify your network routing and security. With Transit Gateway, you can connect your Virtual Private Clouds (VPCs) that span multiple accounts […]

Creating a single internet exit point from multiple VPCs Using AWS Transit Gateway

In this post, we show you how to centralize outbound internet traffic from many VPCs without compromising VPC isolation. Using AWS Transit Gateway, you can configure a single VPC with multiple NAT gateways to consolidate outbound traffic for numerous VPCs. At the same time, you can use multiple route tables within the transit gateway to […]

Integrating AWS Transit Gateway with AWS PrivateLink and Amazon Route 53 Resolver

I want to take some time to dive more deeply into a use case outlined in NET301 Best Practices for AWS PrivateLink. The use case involves using AWS Transit Gateway, along with Amazon Route 53 Resolver, to share AWS PrivateLink interface endpoints between multiple connected Amazon virtual private clouds (VPCs) and an on-premises environment. We’ve seen […]

Centralized DNS management of hybrid cloud with Amazon Route 53 and AWS Transit Gateway

A successful hybrid networking strategy goes beyond private network connectivity. It often requires dealing with independent internal zones both in Amazon Virtual Private Cloud (Amazon VPC) and on-premises. Such a strategy needs Domain Name System (DNS) naming that spans the entire network. Typically, this is managed by providing name resolution services in the same place […]
