Explain the features of AWS Transit Gateway

In this recipe, we will learn about AWS Transit Gateway. We will also learn about the features of AWS Transit Gateway.

Recipe Objective - Explain the features of AWS Transit Gateway?

The AWS Transit Gateway is a widely used service and is defined as a central hub that connects the Amazon Virtual Private Clouds (VPCs) and on-premises networks. This streamlines the user's network and eliminates complicated peering relationships. It functions as a cloud router, establishing new connections only once. Inter-Region peering connects AWS Transit Gateways via the AWS global network as users expand globally. User's information is automatically encrypted and never sent over a public network. AWS Transit Gateway Network Manager has a unique view of your whole network, even connecting to Software-Defined Wide Area Network (SD-WAN) devices, thanks to its central location. This streamlines the user's network and eliminates complicated peering arrangements. It functions as a cloud router, establishing only one new connection at a time. Inter-Region peering uses the AWS global network to link AWS Transit Gateways as users expand internationally. Users' information is automatically encrypted before being sent over the internet. AWS Transit Gateway Network Manager also has a unique view of the user's whole network thanks to its central location, which allows it to connect to Software-Defined Wide Area Network (SD-WAN) devices.

Benefits of Amazon Transit Gateway

  • AWS Transit Gateway serves as a cloud router, making users' network design easier to manage. The complexity of maintaining incremental connections does not slow the down as their network increases. When developing worldwide applications, users can use inter-Region peering to connect AWS Transit Gateways and thus it provides easier connectivity. Users can simply monitor their Amazon VPCs and edge connections from a central console with AWS Transit Gateway Network Manager. AWS Transit Gateway Network Manager integrates with popular SD-WAN devices to enable you quickly discover faults and respond to events on their global network and thus provide better visibility and control. The traffic between an Amazon VPC and an AWS Transit Gateway is routed through the AWS global private network and not over the public internet. All traffic is encrypted via AWS Transit Gateway inter-Region peering, and there is no single point of failure or bandwidth bottleneck. This aids in the prevention of distributed denial of service (DDoS) assaults as well as other typical exploits and thus it improves security. Multicast capability in AWS Transit Gateway sends the same content to numerous particular destinations. This eliminates the need for costly on-premises multicast networks while also reducing the bandwidth required for high-throughput applications like video conferencing, media, and teleconferencing and thus provides a flexible multicast.

System Requirements

  • Any Operating System(Mac, Windows, Linux)

This recipe explains AWS Transit Gateway and its features of AWS Transit Gateway.

Features of AWS Transit Gateway

    • It provides Routing

Between Amazon Virtual Private Clouds (VPCs) and VPN, AWS Transit Gateways offers both dynamic and static layer 3 routings. Routes can point to an Amazon VPC or a VPN connection, and they decide the next hop based on the packet's target IP address.

    • It provides edge connectivity

VPN connections can be established between users of AWS Transit Gateway and on-premises gateways. Users can set up numerous VPN connections to broadcast the same prefixes and use Equal Cost Multipath (ECMP) between them. ECMP can boost bandwidth by load-balancing traffic across different channels.

    • It provides connectivity to the transit gateway

Software-Defined Wide Area Network (SD-WAN) appliances can be natively integrated into AWS via AWS Transit Gateway Connect. Customers can now use common protocols like Generic Routing Encapsulation (GRE) and Border Gateway Protocol to extend their SD-WAN edge into AWS (BGP). It gives customers additional benefits including greater bandwidth and dynamic routing with expanded route restrictions, eliminating the need for numerous IPsec VPNs between the SD-WAN appliances and the Transit Gateway.

    • It provides Interoperability as a feature of Amazon VPC.

When requested from Amazon VPCs that are also connected to the AWS Transit Gateway, the AWS Transit Gateway can resolve public DNS hostnames to private IP addresses. A NAT gateway, Network Load Balancer, AWS PrivateLink, and Amazon Elastic File System in other Amazon VPCs that are likewise connected to the AWS Transit Gateway can be accessed by an instance in an Amazon VPC.

    • It provides Monitoring

AWS Transit Gateway generates statistics and logs that are then used by Amazon CloudWatch and Amazon VPC Flow Logs, among other services. Users can use Amazon CloudWatch to collect bandwidth use, packet flow count, and packet loss count between Amazon VPCs and a VPN connection. On AWS Transit Gateway, you may also enable Amazon VPC Flow Logs to capture information on IP traffic routed through the AWS Transit Gateway. AWS Transit Gateway Network Manager has events and metrics for monitoring the quality of your global network, both in AWS and on-premises. Changes in topology, routing, and connection status are specified through event notifications. Metrics on up/down connections, bytes in/out, packets in/out, and packets dropped are also available. Gateway.

    • It provides excellent Management

To construct and administer the AWS Transit Gateway, users can use the command-line interface (CLI), AWS Management Console, or AWS CloudFormation. The number of bytes transferred and received between Amazon VPCs and VPNs, the packet count, and the drop count are among the Amazon CloudWatch metrics provided by AWS Transit Gateway. users can also use Amazon VPC Flow Logs with AWS Transit Gateway to collect data on IP traffic passing through the AWS Transit Gateway attachment.
