Introduction to AWS Transit Gateway and its use cases

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

Recipe Objective - Introduction to AWS Transit Gateway and its use cases?

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. Users' 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 users' networks 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 users' 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 uses cases of AWS Transit Gateway.

Use cases of AWS Transit Gateway

    • It provides a use case for delivering applications all around the world

AWS Transit Gateway enables you to create applications that span thousands of Amazon Virtual Private Clouds (VPCs). This means that new apps can be deployed without having to update enormous route tables to establish peering relationships. It's a lot easier to set up, maintain, and fix everything now.

    • It provides a use case for moving rapidly to the global scale

Everything connected to an AWS Transit Gateway is shared between AWS Regions using inter-Region peering. VPCs, DNS, Microsoft Active Directory, and IPS/IDS are all included.

    • It provides a use case for smoothly respond to demand increases

Without having to deal with complex connections or enormous routing tables, users can simply add Amazon VPCs, AWS accounts, VPN capacity, or AWS Direct Connect gateways to meet unexpected demand using AWS Transit Gateway.

    • It provides a use case for multicasting apps that can be hosted in the cloud.

Users can host multicast applications using AWS Transit Gateway's multicast capability without having to rewrite their application or change their on-premises network. Users can multicast applications grow based on demand, eliminating the need to purchase and maintain specialised hardware to handle peak demands.
