You can integrate AWS Site-to-Site VPN with Transit Gateway, using the Transit Gateway VPN attachment. AWS managed VPN endpoints support automated redundancy and failover built into the AWS side of the VPN connection. With up to 100-Gbps port connectivity and MACsec encryption, you can secure and scale AWS hybrid connectivity architectures. AWS Site-to-Site VPN is fast to provision and supports encrypted connectivity. Direct Connect helps you to comply with regulations that mandate private network connectivity to the cloud, and may also lower your data transfer costs. Using AWS Direct Connect, you create a private connection between AWS and your data center, office, or colocation environment. This can increase bandwidth throughput and provide a more consistent network experience than internet-based connections. If you have such requirements, you can use AWS Outposts for consistent experience both on premises and in the cloud.ĪWS Direct Connect and AWS Site-to-Site VPN are two commonly used methods to interconnect and create a hybrid network. There could be requirements, such as low latency processing and/or data residency. With the other approach, you may intend to maintain IT resources both on premises and in the cloud and will continue to operate in a hybrid state for the long term. The first approach is to migrate all existing IT resources to the cloud and require short to medium-term hybrid connectivity to migrate assets before shutting down data centers. We see our customers adopting two types of approaches to hybrid connectivity to data centers. All traffic stays on the AWS backbone.įigure 1: Connectivity within AWS, focus area of network transformation highlighted in red.Ĭonnectivity to data centers: Provides hybrid connectivity by connecting data centers to the AWS Cloud. You can route traffic from any resource in one AWS Region to any resource in another AWS Region. Inter-Region connectivity is done using Transit Gateway peering. Each VPC within an AWS Region has optional access to interface VPC endpoints that are powered by AWS PrivateLink. VPCs are interconnected with Transit Gateway. In the following diagram (figure 1), we show a multi-VPC architecture in each AWS Region. This is recommended when you want to use services securely within the AWS network, with all network traffic staying on the global AWS backbone, without the need for an Internet Gateway (IGW) attached to your VPC. You can also securely access your applications in other VPCs using AWS PrivateLink.
