Virtual Gateways simplify branch network deployments for organizations intending to migrate their infrastructure to cloud providers such as Amazon.
Aruba supports instantiating Virtual Gateways on Amazon Web Services Web services allow businesses to share and process data programmatically. Developers who want to provide integrated applications can use the API to programmatically perform actions that would otherwise require manual operation of the user interface. (AWS) Elastic Compute Cloud (EC2) virtualized environment. Network administrators can deploy an AWS EC2 instance with enhanced networking option that uses single root I/O virtualization (SR-IOV)-enabled Ethernet Ethernet is a network protocol for data transmission over LAN. Network Interface Card (NIC Network Interface Card. NIC is a hardware component that allows a device to connect to the network. ).
The AWS EC2 instance is created from OS images in Amazon Machine Image (AMI) format. The ArubaOS VMC image is used for creating and registering the Virtual Gateway AMI. To obtain the AMI for Virtual Gateway, contact your Aruba sales representative.
Aruba Central supports deploying and managing Virtual Gateways hosted on the Amazon AWS VPCs using one of the following methods.
- Orchestrated mode—In the orchestrated mode, Aruba Central enables administrators to deploy Virtual Gateways using the orchestrator application in Aruba Central. The Virtual Gateway orchestrator in Aruba Central imports VPCs from an AWS account, deploys, connects, and enables you to manage Virtual Gateways from Aruba Central. For step-by-step instructions on deploying Virtual Gateways in the orchestrated mode, see Deploying Aruba Virtual Gateways in AWS (Orchestrated Mode).
- Manual mode—In the manual mode, Virtual Gateways must be manually deployed and launched from the cloud provider console. Aruba Central enables you to generate user data for such deployments and manage Virtual Gateways from Aruba Central. For step-by-step instructions on deploying Virtual Gateway in manual mode, see Deploy Aruba Virtual Gateways in AWS.
