Virginia Tech uses AWS Transit Gateway (TGW) for connectivity between VPCs on AWS and Virginia Tech campus. You can read more about AWS Transit Gateway. Network Engineering and Operations (NEO) manages this service. TGW is a regional service. NEO currently has a TGW in
In order to connect to the TGW, NEO must first share the TGW created in
vtnis-ss account with the customers. Customers must then accept the resource share. At this point customers can create TGW VPC attachments to the TGW and add campus routes in the route table pointing to TGW VPC attachment.
NEO has streamlined this process to reduce the workloads on customers having to manage the TGW Resource sharing, TGW VPC attachments and the route tables. Instead customers have to provide NEO with limited access to their accounts using an IAM role and tag resources appropriately, so automation manifests can recognize the resources. Below flowchart depicts this workflow:
Below are the customer requirements stated in the workflow above:
us-east-1is the only region NEO supports.
Tagging is very important for this workflow and will result in failures or errors if the resources are tagged with wrong keys and values.
Once the customer creates all the above requirements, they must a SN ticket with
NIS-Platform. This request collects the following details:
Once the request is received NEO will acknowledge the request and will reach out to the customer for more information if needed. If you have any queries related to AWS Transit Gateway or AWS VPC connectivity to VT campus please submit a 4help incident.
