Enterprise SDN Spend to Reach $10 Billion by 2019

As more multinational companies plan for their digital transformation, most are assessing their communication network capabilities. Meanwhile, the enterprise software-defined networking (SDN) market is maturing, and increasing adoption indicates that it's gaining momentum.

SDN early-adopters are completing proof-of-concept trials and shifting to production deployments, which will transition into mainstream market adoption between now and 2020, according to the latest worldwide market study by Technology Business Research (TBR).

"SDN will become a substantial contributor to the overall network infrastructure market," said Krista Macomber, data center analyst at TBR.

Production deployments have started within large-scale enterprise environments, and will spread as international standards bodies finalize their work and SDN vendors expand into new use cases.

According to the TBR assessment, previously a small number of large vendors dominated networking standards, but openness and collaboration around SDN innovation has included a variety of companies -- including start-ups that have developed new technologies.

With the support of industry alliances, such as the Open Networking Foundation (ONF), and participation from vendors of open-source technologies, SDN now includes security and mission-critical application availability.

Deployment considerations will increasingly include business benefits as enterprises validate the reliability and performance of SDN architectures. Besides, a primary advantage of SDN is the promise of lower-cost infrastructure, by combining savings from open source hardware.

TBR believes that customers recognize the potential of software-defined architectures in solving pressing traditional IT pain points, such as management complexity and workload inflexibility.

However, some barriers to adoption remain -- including internal IT organization resistance to change and industry immaturity. For vendors, proving the performance and reliability of solutions is a critical first step in their market development.

The rise of SDN architectures is altering the vendor landscape. As hardware becomes a commodity, software-centric vendors and vendors of industry-standard hardware may be able to take market share from the traditional enterprise networking industry incumbents.

As software-centric vendors enable customers to reduce expensive and complex hardware installations, they will stress the value of SDN optimization for overlay capabilities and also to improve the performance of IT workloads.

Digital Transformation Growth Defies Market Volatility

The forward-looking CEO's commitment to ongoing investment in Information Technology (IT) is persistent. Worldwide IT spending is forecast to total $4.4 trillion in 2022 -- that's an increase of 4 percent from 2021, according to the latest worldwide market study by Gartner, Inc.   "This year is proving to be one of the noisiest years on record for CIOs," said John-David Lovelock, vice president at Gartner . Regardless, digital transformation remains a high priority across the globe. Geopolitical disruption, inflation, currency fluctuations, and supply chain challenges are among the many market volatility factors vying for attention, yet contrary to what Gartner saw at the start of 2020, enterprise CIOs are accelerating IT investments in 2022. Digital Transformation Market Development As a result, purchasing and investing preferences will be focused on areas including data analytics, cloud computing, seamless customer experiences, and IT security. Inflation impacts on

IoT Device Management Demand Gains Momentum

More forward-thinking CIOs and CTOs are focused on the adoption of the Internet of Things (IoT). Management challenges are top of mind for those who have already deployed a large number of sensors and associated network edge devices. Device management services are evolving in response to a greater breadth of new device technologies such as edge intelligence and related connectivity solutions, as well as the customer scalability and security of IoT deployments. But forward-looking suppliers are also preparing for a world where 41.3 percent of the connected devices will be using some form of Low Power Wide Area (LPWA) technologies by 2026. IoT Device Management Market Development Since IoT customers increasingly need to manage a larger fleet of connected devices, ABI Research now forecasts that IoT device management services will exceed $36.8 billion in revenues by 2026. Standardization is beginning to play a bigger role in device management services, as more connected devices use LPWA t

Anywhere, Anytime Workplace Demand for SASE

The ongoing adoption of flexible working models within the enterprise market has significant implications for typical IT organizations that must now support knowledge workers and front-line employees that operate outside the corporate network perimeter. The global COVID-19 pandemic created IT networking and security challenges. The expansion of the distributed workforce, an increasing reliance on cloud computing infrastructure, and the requirement to securely connect online employees -- wherever they choose to work, at any given moment in time. Legacy IT solutions that have rigid network underlays and a requirement for on-premises infrastructure cannot adequately deal with these trends. This 'Anywhere, Anytime Workplace' led to demand for new Secure Access Service Edge (SASE) solutions, with networking and security delivered as-a-service.
