BrandPost: Your Roadblock to Becoming Digital: A 1990s Server Room

Digital transformation is fundamentally changing businesses of every size. Larger enterprises no longer have a unique advantage based purely on their scale. Small and midsize businesses (SMBs) can utilize new applications and services that allow them to compete toe to toe against a business or organization of any size. Not only do your customers want the latest and greatest, but employees demand it as well. If your employees can’t get the digital tools they need to be successful, they’ll go where they’re available.The focus of management and employees today is on exciting new apps and services. However, without the appropriate IT infrastructure to support them, an organization will not be able to move forward on the digital transformation journey. New apps and new devices are dependent on the servers, storage, and network gear that provide the data and back-end services.  Unfortunately for many SMBs, IT equipment is stored in a 1990s server room that may be a repurposed conference room, cubicle, or spare office that cannot provide the physical environment the IT hardware needs to support a 21st century organization.To read this article in full, please click here

Startup ZincFive makes old battery technology new again

A startup called ZincFive is set to launch a modular uninterruptible power supply (UPS) for data center computers using the venerable nickel-zinc technology, which it claims is more efficient than lithium-ion.Nickel-zinc batteries were invented by Thomas Edison in 1901 but fell out of favor to newer designs due to their limitations, such as a low number of charge cycles and their inability to hold a charge for long.On the plus side, the batteries could hold a stronger charge and didn’t use toxic metals like other batteries that make them difficult to recycle. And they are not flammable, something lithium-ion batteries certainly can’t claim.To read this article in full, please click here

IDG Contributor Network: What to understand about health care IoT and its security

IDG Contributor Network: IoT security: whose job is it anyway?

It’s been nearly two decades since the coining of the term “Internet of Things,” yet we are still asking the same question: “Whose responsibility is it to secure the billions of IoT devices?” Given the market’s progress of late, you would think we’d have it figured out by now; but, it’s not that simple.Although IoT security has long been a hot topic of discussion, it has become more important—and more challenging – than ever. First, gone are the days when operational technology (OT) was single-handedly responsible for securing IoT, often taking a “security by obscurity” approach by physically separating production operations and industrial networks from enterprise networks and the Internet. Although enterprises are realizing the need to converge IT with OT to drive new use cases, enable an open flow of data between networks and applications, support better business decisions, lower costs, and reduce complexity, new attack surfaces are arising between the gaps in IT and OT practices.To read this article in full, please click here

IDG Contributor Network: Submarine cable boom fueled by new tech, soaring demand

It’s been 160 years since the world’s first submarine cable linked a remote corner of Trinity Bay, Newfoundland, with Valentia Island on the west coast of Ireland in 1858. That telegraph cable failed after three weeks, but a new method for transoceanic communications had been established, and today submarine cables are a critical piece of digital infrastructure that’s fast expanding in prevalence and prominence globally – though not yet quickly enough to meet voracious demand for capacity.Between 2013 and 2017, the subsea cable industry has added an average of 32 percent of capacity annually on major submarine cable routes, according to the industry magazine SubTel Forum. Still, the industry needs to do more. “It will have to increase activity to stay ahead of demand,” SubTel Forum said in its annual report this year.To read this article in full, please click here

IDG Contributor Network: Digital transformation of cities: Creating smart and engaged communities with IoT

What makes a city a “smart city?” Some would argue that it has to do with the degree to which the city is staying abreast of technology advancements, but that is too one-dimensional. Smart cities require an integrated approach to IoT, connectivity, AI, distributed computing and other technologies.To truly capitalize on smart city technology, technologists must understand the immediate and long-term pain points for city governments; the procurement framework including budgetary and funding issues; and the overall bureaucratic and legislative processes.An integrated approach to technology implementation – cutting across all departments in the city – can help alleviate specific challenges such as parking management, traffic management, street lighting, energy consumption (and demand response), and public safety.To read this article in full, please click here

BrandPost: What Is an Autonomous Network?

Automation itself, and the idea that technologies could be self-provisioning, self-diagnosing, and self-healing, has been around for some time. But with advances in Artificial Intelligence (AI) and cloud technologies, such fanciful notions are quickly becoming realities.Nowadays, most of us use AI-enabled apps when we ask Apple’s Siri or Amazon’s Alexa for help with a task. And even streaming services like Netflix help us pick movies and TV shows using AI.WHITE PAPERIntroducing the Adaptive Network VisionTo read this article in full, please click here

Companies ready to spend on IT hardware again

In-house IT hardware spending has been on hold thanks to executives flip-flopping on whether to move to cloud computing. It hasn't been because they've actually shifted to cloud services.The problem has been merely inertia caused in companies by "decision-making around the cloud," says Morgan Stanley in a new financial research note published this week. The financial services firm suggests that once enterprises complete their cloud assessments, their checkbooks will open once more.Also read: Top 10 data center predictions: IDC In fact, Morgan Stanley, which advises people on industry investments, says investors could see double-digit earnings growth from the IT hardware sector in 2018.

Leveraging Windows Server 2016 for hyperconvergence

With the release of Microsoft Windows Server 2016 a couple years ago, Microsoft directly entered the hyperconverged infrastructure (HCI) platform space that has been served by organizations like Nutanix, Scale, Cisco, HP, Dell, and others — only Microsoft comes at it with a fully software-defined platform rather than hardware and applicances.The underpinnings HCI environments are based on the following: Scalable and Shared Compute: The ability to aggregate processing power beyond a traditional “server” with two or four sockets spanning a finite 24, 32, 64 cores to an array of multiple servers where the core processing capabilities brings together four, eight, 16, or more servers with hundreds of cores that can be shared and allocated to workloads as needed. Scalable and Shared Storage: The core storage component of HCL is very similar to the traditional Storage Area Network (SAN) model of the past decade where dozens of drive subsystems are spanned for high performance and capacity and allocated to workloads as needed. Flexible and Customizable Networking: The networking component of HCI provides virtual networks that isolate traffic and shape communications to optimize the workload to workload communications for performance and security purposes HCI compute on Windows Server 2016 — based Continue reading

Super Bowl LII set football and Wi-Fi network records

Super Bowl LII was played about a month ago, and much to the chagrin of New England Patriots fans, the team lost despite a number of records being set by Tom Brady and his team. In a losing effort, the QB threw for over 500 yards, something that had never been done before. Also, no losing team has ever had as many yards or points. It was certainly one of the most memorable games in recent history, particularly for the long-suffering Philadelphia Eagles fans.Records were also set in the stands with new highs in Wi-Fi network usage. For the fifth consecutive year, Extreme Networks was the Official WiFi Analytics provider of the Super Bowl, and its ExtremeAnalytics (formerly known as Purview) captured all the data transferred over the stadium Wi-Fi network. (Note: Extreme is a client of ZK Research.) The NFL and its individual teams have been using the data to better understand what fans do on their mobile devices during games in hopes of creating an overall better experience. Some of the highlights from the big game are listed below.To read this article in full, please click here
