How SD-WAN Will Improve Managed Network Services in 2020 and Beyond?

By Enterprise Networking Mag | Monday, February 17, 2020

With network operators providing more improved SD-WAN services in 2020, the demand for managed services will see some significant changes in size, feature sets, and management.

FREMONT, CA: Organizations have maintained their network infrastructure. But, from the time operators initially started offering VPN services, the organizations have adopted the managed network services to the relief of operations burdens. That same driver will continue and expand in 2020.

Managed services have been the chief vehicle for SD-WAN delivery from the initial stage onwards. The sites where the MPLS VPNs are impractical are the same sites where it's difficult for organizations to maintain network support. Local labor pools hardly contain the skills needed, for instances, and branch locations don't present personnel realistic career paths. Even in areas that can provide the necessary skills, the cost of staffing these locations is relatively high because of the personnel can't serve other missions in small offices.

SD-WAN's initial value proposition was the ability to expand VPN to locations where MPLS VPNs were unavailable or very expensive. In previous years, SD-WAN technology modernized and developed the VPN model. The growth of broadband internet, even in the areas with restricted business populations, makes sure of further expansion in this year.

SD-WAN leverages the excessive bandwidth of relatively not secured internet connections, potentially exposing branch locations and edge devices to security attacks and breaches. As a result of this, SD-WAN deployments need additional security to make sure that the corporate policy is forcing at distributed locations. Security features should comprise of traffic visibility, policy controls, and protection against direct threats and attacks.

In 2020, managed network services will extend to cover network support to the on-site systems and users. That means that the on-site networking tools will frequently be considered extensions of the company VPN and be tying to VPN technologies, especially SD-WAN. That needs end-to-end network awareness at all levels of the network from desktop to phone to the data center.

The first change regarding managed services is a reduction in MPLS VPN pricing, which initially affects the low end of currently supported sites. This reduction is an operator reaction to the risk of displacing MPLS sites with internet-connected SD-WAN, and it will gradually minimize small-site costs for VPN connectivity by as much as a third. There will be a general trend via lower MPLS VPN pricing, even beyond 2020, because SD-WAN will motivate operators to minimize the immediate financial benefit of shifting to SD-WAN. This will result in a smaller, but coordinated reduction in pricing for SD-WAN managed services.

SD-WAN is integral to IT infrastructure, so it must seamlessly scale to hundreds or thousands of locations and play well with the existing network- and application-management platforms. SD-WAN providing companies have a long way to go before they give the promise of complete automated, intent-based WANs.

At present, the SD-WAN providing companies will improve the ability to aid to identify the cause of application-performance slowdowns or outages easily, quickly connect IoT devices, view the status of the network and unify multiple management consoles. SD-WAN platforms offer pre-set, high-priority policies for real-time applications like unified communications and video. In 2020, SD-WAN providers will ceaselessly improve the automation of policies designed to deliver appropriate QoS to critical SaaS applications without IT intervention.

 To date, 4G/LTE wireless has typically confined to WAN back-up or limited entirely to first turn-up use cases due to bandwidth limitations and cost considerations. In 2020, the enterprises can see the constraints addressed on both the technology front, with 5G, and on the business front with service providers providing attractive pricing for an expanding range of SD-WAN use cases that leverage wireless connectivity.
