The deployment of the Nexus 1000V on AWS often worked in tandem with the Cisco Cloud Services Router (CSR) 1000V. While the Nexus 1000V managed the Layer 2 switching and internal network segmentation, the CSR 1000V handled the Layer 3 routing and VPN connectivity back to the enterprise data center. Together, these two virtual appliances created a robust software-defined networking (SDN) stack within the cloud. This combination enabled enterprises to replicate complex network topologies, such as hub-and-spoke models or transit VPC architectures, using Cisco technologies that their staff already understood.
Essentially, it turns an AWS instance into a fully functional Cisco router, providing familiar command-line interface (CLI) control and feature parity with hardware counterparts. Key Features and Capabilities cisco 1000v aws
Before the advent of AWS Transit Gateway, the CSR 1000V was the primary engine for "Transit VPC" designs. It acts as a central hub, routing traffic between multiple VPCs and on-premises locations, providing a single point of management and auditing for all cloud traffic. 4.
