Customers frequently use on-premises DNS infrastructure to resolve DNS queries for internal domains. In 2018, we announced Amazon Route 53 Resolver endpoints, which enable customers to integrate Route 53 with their on-premises DNS infrastructure for hybrid DNS resolution. In 2023, we improved this integration by providing customers the ability to encrypt DNS queries and responses […]

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 […]

Today, on 30th August 2023, AWS launched a new enhancement to the Amazon Virtual Private Cloud (Amazon VPC) Ingress Routing feature. With this enhancement, customers can now specify a Gateway Load Balancer Endpoint (GWLBE) as the next-hop in the virtual private gateway (VGW) route table. This allows customers to inspect their traffic coming into AWS […]

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, […]

AWS Site-to-Site VPN is a fully-managed performant, scalable, secure, and highly-available way to connect your on-premises users and workloads to AWS. When using Site-to-Site VPN you can connect to both Amazon Virtual Private Clouds (Amazon VPCs) with two tunnels per connection for increased redundancy. For even greater performance with sites further from your AWS Region(s), […]

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 […]

We’ll also analyze the behavior from different viewpoints including service availability, management and governance, as well as commercial and operations. […]

Update 10/13/22: Added walkthrough with the AWS Management console and link to code in CDK and Terraform. One of the most common ways that customers connect securely to AWS from on premises is by using the AWS Site-to-Site VPN managed IPSec VPN solution. One key benefit our customers look for when using the service is […]

A common situation we see in customer networks is when there are resources with overlapping IP address ranges that must communicate with each other. Frequently this occurs when companies are acquired and have used the same private (RFC1918) address ranges. However, it can also occur when a service provider with a unique IP range must […]

Do you need to either demonstrate or learn more about using certificate-based authentication with AWS Site-to-Site VPN capabilities? In part 1 of this series, we showed how to use an AWS CloudFormation template to deploy the open source strongSwan VPN solution to implement the on-premises side of an AWS Site-to-Site VPN connection. The open source […]
