Cloud Gateways

To those ends, VeloCloud’s architecture consists of three layers. The first layer are the cloud gateways. This layer includes VeloCloud’s worldwide network of cloud gateways that sit on top of the underlying transport. The cloud itself can be VeloCloud’s cloud or a private cloud. Private clouds can be run by the service provider or by an enterprise, who will be able to deploy the gateways in their PoP locations.

Service Delivery Layer

VeloCloud’s second layer is the services delivery layer. This layer includes VeloCloud’s network services, all of which resellers and service providers can provide to their own customers. Among these services are pre-prepared QoS and firewalls, which can be enabled or disabled. When offering VeloCloud as a service, service providers will be able to provide their customers with the VeloCloud dashboard and the ability to see who is using or abusing their network and whether their investment is paying off. VeloCloud also provides VPN (virtual private networks), which can be done edge to edge. Lastly, this layer allows service providers to easily build dynamic tunnels back to the data center or between edges.

Orchestration

VeloCloud’s third layer concentrates on orchestration,  as well as providing visualization, network services insertion, and business policy automation. Service providers leverage these capabilities to easily resell VeloCloud services to their customers while retaining control and monitoring abilities.

VeloCloud’s orchestrator provides visibility and QoS information, as well as an application-level policy and controlled QoS management from a single console. This is true even when the orchestrator is disconnected, regardless of whether an enterprise uses internet, VPN, or a hybrid WAN. Edge nodes are used to connect to gateways within a provider’s network, making expansion easy; the orchestrator automatically configures the new edge node and  updates routing information at existing edge nodes.

Service Providers

VeloCloud has made a strong play at selling through service providers and telcos. As service providers grow, they need to adapt to meet customer needs. Service providers need to give their customers advanced service and increased flexibility, while maintaining revenue as customers reduce their dependence on profitable MPLS networks.

VeloCloud provides service providers with the ability to offer elastic transport and performance for cloud applications, while integrating the new SD-WAN with existing networks. Service providers enjoy optimal and direct access to cloud-based applications, on-demand bandwidth, and improved operational automation.

To help service providers and telco carriers easily deliver SD-WAN services, VeloCloud  provides zero-touch deployment for easy installation, configuration, operations, and maintenance processes, thereby eliminating the need for service providers to visit each physical location to install.

For service providers, VeloCloud’s easy installation eliminates the need to to create separate VPN tunnels for each customer and manually manage each of them. Instead, service providers will be able to use the UI to create a customer profile. This profile will automatically build the appropriate tunnel.

Use of multi-tenant gateways and orchestrators mean VeloCloud scales horizontally, allowing a single orchestrator to manage several customers. This also provides the ability to light up specific VMs (virtual machines) to allow private head ends for customers who want the separation.

Types of SD-WAN models

VeloCloud offers two types of SD-WAN models: OTT (over the top) and network integrated. The difference between these two solutions is in how the overlay edge nodes are managed.

OTT

A “network integrated” solution offers SD-WAN overlay edge nodes as multi-tenant virtual gateways. These are then deployed in data centers and the service provider network. Hosted services are provided by deploying gateways at cloud data centers, and private MPLS networks use gateways deployed at provider edge POPs.

Network Integrated

In a network integrated solution, the orchestrator and controllers are deployed as either publicly accessible or within an enterprise’s individual network.

Service providers  benefit from VeloCloud’s network integrated architecture, which ensures all last mile circuits – including broadband internet – have access to the enterprise’s existing private MPLS network. These networks are especially valuable for long distance communications.

Network integrated architecture also eliminates the need for enterprise data center installations and ensures enterprise sites using the private network will be easily accessible via SD-WAN deployment. Connectivity from private MPLS networks to cloud data centers is possible at SD-WAN enabled branches.
