ISG Provider Lens™ report sees U.K. businesses exploring vendor-agnostic solutions and the advantages SDN technologies can provide

LONDON, Aug. 26, 2019 /PRNewswire/ -- Enterprises in the U.K. are looking to software-defined networking and related technologies as a way to become more agile and flexible while meeting the growing needs of critical applications, according to a new report published today by Information Services Group (ISG) (Nasdaq: III), a leading global technology research and advisory firm.

The 2019 ISG Provider LensNetwork – Software Defined Solutions and Services U.K. Report finds some U.K. enterprises embracing SDN technologies, even as others are hesitant due to the complexity and hype surrounding the technology. Many enterprises are seeking an agile and step-by-step approach to move from traditional to automated and, finally, autonomous networking technologies, the report says.

The report also sees data centers driving adoption of SDN-related technologies, focused more on mobility and agility than on business case. Still, some enterprises see challenges with architectural complexity, vendor restrictions, troublesome migration and application mobility and portability constraints when moving to SDN-related technologies, the report says.

Vendor lock-ins, in particular, are still plaguing the SDN market in the U.K., the report says. Some networking technology providers are exploring vendor-agnostic solutions, and this change will make it easier for customers to leverage their existing investments while exploring SDN technologies.

Many U.K. enterprises recognize the advantages of SDN and the related network function virtualization technology, the report says. SDN can improve the application hosting landscape because multi-cloud network collaboration is necessary to cater to new network collaboration environments. Vendors are crafting SDN solutions to provide networks that offer centralized controllers to support unified visibility into the entire network infrastructure.

"The network is moving toward virtualization," said Barry Matthews, partner and head of ISG U.K. "Virtual network functions are key to unlocking meaningful automation and orchestration, and SDN-related technologies improve agility by completely doing away with racking and stacking devices."

In addition, telecom service providers are using SDN technologies to address customer preferences for mobile network service over Wi-Fi, the report says. A move toward 5G mobile services is driving customers to consider SDN to reduce the time it takes to transition from 4G networking.

SDN also helps enterprise customers reduce costs by prioritizing applications based on the bandwidth required, the report says. SDN allows customers to re-route the required bandwidth needed to balance application priorities.

Many providers of networking products and services are involved in SDN-related pilot projects and are regularly converting them to production-level deployments, the report adds. Many networking vendors are embracing SDN products as a way to improve their positioning in the marketplace.

The 2019 ISG Provider LensNetwork – Software Defined Solutions and Services U.K. Report evaluates the capabilities of 51 providers across seven quadrants: Managed WAN Services; Mobile Network (4G/5G) Additional (non-core) Services; SDN Transformation Services (Consulting and Implementation); SD-WAN Equipment and Services (DIY); SDN Security Services; SD Network Technologies (Core), and SD Network Technologies (Mobile to Edge).

The report names IBM and Orange Business Services as leaders in all seven quadrants, and T-Systems and Vodafone as leaders in six. BT is named a leader in five quadrants, HCL a leader in four, and Cisco, Infosys and Wipro as leaders in three. TCS is named as a leader in two quadrants and Dell EMC, Tech Mahindra and VMWare are named leaders in one.
