Cisco vEdge Cloud is a software router platform that supports an entire range of capabilities available on the physical vEdgerouter platforms. The vEdge Cloud router is offered as a virtual machine that can be deployed in the variety of private, public, and hybrid cloud computing environments. It is supported on all major hypervisor platforms.
Cisco vEdge Cloud router uses the Intel DPDK infrastructure to help ensure the most optimal performance on x86 platforms. The software is also capable of using the AES-NI encryption offload technology available on most Intel platforms. AES-NI offers optimized IP security (IPSec) performance when using AES encryption algorithms.
The vEdge Cloud router targets the following main deployment use cases:
1. Extending SD-WAN overlay into public cloud environments
2. Virtualized WAN router
1. Extend SD-WAN Overlay into Public Cloud Environments
Hybrid cloud is now the new norm for enterprises. With hybrid cloud, certain enterprise workloads remain within the boundaries of the private data centers, while others are hosted in the public cloud environments, such as Amazon Web Services (AWS) and Microsoft Azure. This approach provides enterprises with the utmost flexibility in consuming compute infrastructure as required.
With the Cisco Software-Defined WAN (SD-WAN) solution, you can extend ubiquitous connectivity, zero-trust security, end-to-end segmentation, and application-aware Quality-of-Service (QoS) policies of the organizational WAN into the Infrastructure-as-a-Service (IaaS) public cloud environments.
The transport-independent nature of the Cisco SD-WAN solution allows use of a variety of connectivity methods in the active-active fashion by securely extending SD-WAN fabric into the public cloud environment across all underlying transport networks. These include Multiprotocol Label Switching (MPLS), broadband, 3G/4G LTE, satellite, and point-to-point links.
With the traffic segmentation policies, you can create multiple VPNs on top of a single fabric to functionally segregate different types of traffic between the private and public cloud environments. This behavior results in the end-to-end segregation. Application-aware topologies and intelligent selection of the best performing path toward the public cloud, in accordance with desired Service Level Agreements (SLAs), help ensure optimal overall Quality of Service (QoS). Extensive QoS mechanisms present in Cisco vEdge Cloud software router result in differentiated service for application traffic.
The following figure illustrates how Cisco vEdge Cloud router securely extends organizational WAN into the public cloud environment.

2. Virtualized WAN Router
A branch network consists of a number of elements. Operating, maintaining, and connecting these elements can be simplified by adopting a generic x86 platform on which discrete Virtual Network Functions (VNFs) are instantiated. This form of service delivery is also known as the virtual customer premises equipment or the vCPE. With vCPE, the vEdge Cloud router assumes the role of the WAN router VNF, providing secure WAN connectivity from and to the remote office.
The following figure illustrates Cisco vEdge Cloud router solution elements.
Solution elements of the Cisco vEdge Cloud router
The Cisco SD-WAN solution supports numerous intelligent in-line and off-path methods of integrating the vEdge Cloud router with the rest of the virtual Customer Premises Equipment (vCPE) elements. This integration includes routing, policy-based routing, bridging, and service insertion methods.
Cisco vEdge Cloud routers can be deployed as a redundant active-active pair using either OSPF or BGP protocols for routed environments or VRRP for bridged environments. This deployment helps to ensure a higher degree of connectivity resilience and uptime for the remote offices.
Cisco vEdge Cloud routers can be deployed on a variety of x86 platforms. The following table lists minimum x86 platform requirements.
