How To Use Transit Gateways To Monitor Traffic

Amazon Web Services ( AWS) cloud network connectivity is something many businesses have begun using, as it allows them to create run different network architectures. It has made migration of on premises services to the cloud a lot easier overall. 

In the past, businesses would need to use Virtual Private Cloud (VPC)  peering or Transit VPCs to create a system that allowed for connectivity between between on site centers and applications running in the cloud. This wasn't scalable though, and didn't allow for increased connectivity. 

Transit gateways are a new way of managing traffic through different VPCs and AWS accounts, making it a lot easier to use. Here's how the system works. 

What Is A Transit Gateway?

A transit gateway is a hub that connects up VPCs and on premises networks. It can support all kinds of attachments, from VPCs to VPN connections, SD-WAN network appliances, and AWS gateways too. 

There are several features a network gateway can offer you, so they're worth looking into:

Availability zone: A VPC attachment will create a network interface in the Availability Zone. When this has been enabled, you can use any subnet to route traffic through the transit gateway. 

Routing: You can handle complex routing needs with a transit gateway. You can have both dynamic and static routing tables, according to your needs. Static routes and black hole routes are available to uses, when you need to isolate attachments from each other. 

Inter region peering: Using an inter region attachment, you can peer transit gateways in different regions. This allows you to create global networks and take advantage of low latency communication, essential when your business is spread across different regions. 

Cross account connectivity: An AWS resource access manager can be used to share a transit gateway, and control communication between accounts. 

On premises connection: As a user, you can connect to the transit gateway by using a direct connect gateway. That allows you to connect while being on premises. It also allows for the creation of a backup, if needed. 

Multicast communication: A multicast protocol will allow you to deliver a single stream of data to several hosts at the same time. This is something that's highly useful in several fields, such as those working in video transcoding on the financial fields. 

How To Put Together Transit Gateway Topologies

One of the best things about a transit gateway is that there are lots of different ways you can use them, so you can create topologies according to your needs. Here are some examples you can use. 

Centralized router: This is one of the simplest ways to use a transit gateway. The gateway is used as a centralized router, which connects all attached VPCs, direct connects and so on. This allows all attachments to route packets to each other, and support transitive connectivity. 

Isolated VPCs: There are two different ways you can set up this topology. Firstly, you can use an isolated VPC with shared services. This gives you the addition of a shared services VPC. Each VPC can connect to on site services, but not each other. The other way is to use a peering transit gateways topology. The transit gateways used in different regions are peered together, allowing them to route traffic between them. You can also route traffic from an on site location to VPCs in different regions. 

Appliance shared services VPC: You can use this topology to host an appliance in a VPC, and have all your traffic routed through it. This is a good way to monitor traffic that's being used this way. 

Centralized outbound routing: This allows you to set up all outbound routing to go through a centralized VPC with an internet gateway attached. With this, you won't need an internet gateway for any other VPC that you use. This is often used for enterprise grade deployments. 

There are all kinds of ways you can use a transit gateway in your business. They allow you to change up your network in accordance with your needs, and allow for much easier working. They also help increase connectivity between on premises and cloud based systems. With all this information, you are now in a position set up a network that works for you.
