Not all SD-WAN products were designed for managed services
Enterprises are increasingly looking for cost-effective and simpler alternatives to WAN connectivity and sprawling branch networks. Software-defined WANs (SD-WAN) are an evolving solution that addresses many enterprise requirements around WAN costs, simplified operations and improved application performance.
For service providers building SD-WAN offerings, however, the majority of managed service operational and cost challenges can still exist — the need to deploy proprietary hardware/software at both the branch office and head-end for every end customer, as well as the lack of capability or simple integration with critical security functions like firewalls and secure web gateways.
Versa SD-WAN: designed for agile and efficient managed services
Versa’s VNF-based SD-WAN solution allows service providers to deliver a comprehensive, cost-effective managed SD-WAN service that includes advanced connectivity and security functions.
Based on Versa networking and security VNFs, coupled with commodity hardware, the Versa SD-WAN solution includes key managed service capabilities such as multi-tenancy, multi-service, elasticity and zero-touch provisioning. Multi-tenancy, both at the data center/cloud and branch site, improves service agility when provisioning new customers, as well as significantly lowers capital and operating costs. Multi-service capabilities and service chaining ensure that providers can include critical security functions like next-generation firewall and secure web gateway in their managed service and have them automatically integrate with other networking functions.
With Versa's multi-function VNF, service providers can rapidly design a customized SD-WAN service that combines the primary network functions of application-aware routing, CGNAT and VPN, along with any incremental security functions needed – in a matter of days or weeks, not months or years as hardware-based solutions normally require.
The Versa managed SD-WAN solution has built-in service chaining to easily integrate with existing third party network and security functions in the branch office, further accelerating deployment time and agility.
With the Versa managed SD-WAN solution and its broad set of VNFs, providers can build rich SD-WAN offerings that combine networking and security to yield greater business impact than basic VPN or connectivity-only SD-WAN services.
Because Versa-based SD-WAN services utilize automatic service chaining, providers can initially sell a basic SD-WAN service to customers and up-sell security or other functions over time. The result is higher overall service revenue and customer loyalty.
The Versa SD-WAN solution combines software-based VNFs and low-cost commodity hardware with pay-as-you-use pricing, resulting in much lower capital costs than traditional WAN hardware or hardware-based SD-WAN solutions.
The Versa solution includes full multi-tenancy so Capex is much lower at scale, as additional SD-WAN infrastructure and management is not required at the head-end for each new customer.
Operational costs are minimized through zero-touch provisioning and centralized management, which together eliminate truck rolls and greatly simplify ongoing operations.
Versa gives service providers the ability to create richer managed services that combine SD-WAN capabilities with a range of security functions – all using Versa VNFs.
For example, a provider can integrate SD-WAN functions with a branch-based firewall and URL filtering to create an MPLS + broadband service with secure direct Internet access to cloud apps and resources.
The result is incremental revenue, much better differentiation and less price sensitivity than connectivity-only service offerings.
