Kelvion New Plate Heat Exchanger

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, stated Information Services Group (ISG) in its latest report. These findings match other SDN networking forecasts, and also for example IaaS hosting provider WorldStream’s plans to launch an elastic global SDN networking platform by Q1 2020.

“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.”

The ISG report, ‘2019 ISG Provider Lens Network – Software Defined Solutions and Services U.K. 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.

ISG’s study results are confirmed by Technavio’s report on SDN that was published last month. According to Technavio, the global software-defined networking market is expected to post a CAGR of close to 24% during the period 2019-2023.

WorldStream Elastic Network

Vendor lock-ins, in particular, would still be plaguing the SDN market in the United Kingdom, stated ISG in its report. Some networking technology providers are exploring vendor-agnostic solutions, and this change would make it easier for customers to leverage their existing investments while exploring SDN technologies.

WorldStream is a good example of a global IaaS hosting and network services provider, a fast-growing one we noticed with currently more than 15,000 dedicated servers under management and company-owned data centers in the Netherlands, that is currently developing vendor-agnostic SDN capabilities – with new, fully flexible hosting deployment features. WorldStream’s new to develop SDN network will be called WorldStream Elastic Network and is expected to be officially launched in Q1 2020. The in-house engineered software-defined architecture will add an elastic network platform on top of WordStream’s existing high-bandwidth global network backbone.

“This new elastic SDN-based network on top of the WorldStream global backbone will significantly reduce capital expenses for our customers when coping with ultimate redundancy requirements – such as within healthcare, finance, government, and enterprise markets,” said Tim Vollebregt, Network Director at WorldStream and mastermind behind the soon to release WorldStream Elastic Network.

This in-house engineered WorldStream Elastic Network is intended to bring the company’s global client base ultimate flexibility and tons of added functionality with regard to their hybrid IT infrastructure deployments and data center resource allocation. WorldStream’s new network will come with a comprehensive suite of SDN-enabled new features and interconnection options. It will provide the flexibility to vary connectivity deployments at the local edges of the network real-time based on actual demand. For WorldStream’s service provider customer base this will allow the establishment of new on-demand go-to-market business models including pay-per-use (cloud) hosting service delivery. The software-defined network platform will be cloud-enabled and equipped with the ability to connect to multiple top cloud providers through public cloud onramps.

A key factor driving the global software-defined networking market size is the increasing demand for cloud solutions, stated Technavio in its report. The adoption of cloud solutions is increasing significantly owing to benefits such as the facility to easily scale-up or scale-down the workload. Moreover, there would be a growing need for better infrastructure to handle the increasing network traffic and to address the demand for higher bandwidth requirements. Software-defined networking (SDN) is considered as a potential solution to meet this challenge and is increasingly being adopted by enterprises. Thus, the increasing demand for cloud solutions is expected to stimulate the growth of the SDN market during Technavio’s forecast period, 2019-2023.

Telecom and Enterprise Market

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

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

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

“SDN technology will allow for plug-and-play multi data center setups and twin data center concepts as well,” said Tim Vollebregt, Network Director at WorldStream and mastermind behind the soon to release WorldStream Elastic Network. “It will enable our clients to easily create data center presence at all facilities contained in the WorldStream network backbone, whether WorldStream’s company-owned data centers in the Netherlands are concerned or any of the other data centers worldwide where our server and network equipment reside. This will significantly reduce capital expenses for our customers when coping with ultimate redundancy requirements such as within healthcare, finance, government, and enterprise markets.”

ISG’s ‘2019 ISG Provider Lens Network – 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).
