IDG Contributor Network: Winning together in the co-economy: a new mindset for the 21st century

During the late 20th century, industrial technology providers focused on delivering complete, turnkey solutions by themselves. The thought was that to effectively address highly specialized and complex environments, a vertically integrated approach would produce a better outcome.Today, that mindset has drastically shifted.The accelerated pace of technology innovation has driven end customers to question this single-vendor model. Now, customers are increasingly embracing the open model involving multiple partners developing solutions based on open standards and the latest technology. Such solutions are typically better future-proofed, more cost effective and agile.To read this article in full, please click here

IDG Contributor Network: To accelerate cloud application performance, start by mapping your apps

In the eternal words of Yogi Berra, “If you don't know where you are going, you'll end up someplace else.” So how does this sage advice apply to the new world of application performance and hybrid IT?As the pace of application migration to the cloud continues to accelerate, enterprise networking teams have turned to hybrid and SD-WANs as practical solutions to open up more localized internet access and direct routing to the cloud. So the theory goes that by deploying broadband and internet connections at the edge of the network, users can bypass the MPLS bottlenecks and avoid transiting the centralized data center internet egress points.So with the proliferation of hybrid and SD-WAN deployments, which according to most analysts is well past the tipping point and going mainstream, why is it that enterprise IT teams are still struggling with cloud application performance? User frustration with the performance of applications like Office 365, Salesforce, Workday, ServiceNow, and others is only growing, rather than waning.To read this article in full, please click here

Suddenly the server market is hot again

After years of shrinking sales, the server market is suddenly hot, very hot. According to the latest figures from IDC, worldwide server shipments increased 20.7% year over year to 2.7 million units in Q1 of 2018, and revenue rose 38.6%.This is the third consecutive quarter of double-digit growth, and it’s being driven by a number of factors. They include a marketwide enterprise refresh cycle, strong demand from cloud service providers, increased use of servers as the core building blocks for software-defined infrastructure, broad demand for newer CPUs, and growing deployments of next-generation workloads.Average selling prices (ASP) increased during the quarter due to richer configurations and increased component costs. The increased ASPs also contributed to revenue growth. Volume server revenue grew by 40.9%, to $15.9 billion, while midrange server revenue grew 34%, to $1.7 billion, and high-end systems grew 20.1%, to $1.2 billion.To read this article in full, please click here

IDG Contributor Network: When it comes to your IT infrastructure, visibility matters

CIOs everywhere are faced with a common question: do we have the right infrastructure for our business today and tomorrow? The question is complicated since there is no right answer – even though the major public cloud providers would say otherwise.Most large companies have hybrid infrastructures, comprising internal data centers, private clouds and at least one public cloud service. Increasingly, companies are using more than one public cloud service, as each one has something different to offer and prices are always changing. These choices provide needed flexibility and the potential for carving out the perfect environment for a company’s multifarious needs.To read this article in full, please click here

Cisco taps AMD to power a hyper-dense server for data centers, edge computing

Cisco this week broadened its server family with a high-density box aimed at handling compute intensive data center workloads and distributed edge computing environments.The Cisco C-Series C4200 multinode rack server is a 2RU box comprised of the C4200 chassis and C125 server nodes which Cisco says brings up to 128% higher processor core density and 33% more memory compared to its existing two-socket UCS M5 rack servers.  The C4200 chassis can house up to four server nodes.[ Now see who's developing quantum computers.] “As computing demand shifts from large, traditional data centers to include smaller, more distributed environments at the edge, the ability to mix form factors seamlessly in ‘micro data centers,’ and to manage and automate operations from the cloud becomes vitally important,” wrote Kaustubh Das, Cisco vice president of strategy and product development, storage in its Computing Systems Product Group in a blog about the new server.To read this article in full, please click here

AMD’s EPYC server encryption is the latest security system to fall

It’s a good thing AMD had the sense not to rub Intel’s nose in the Meltdown/Spectre vulnerability, because it would be getting it right back for this one: Researchers from the Fraunhofer Institute for Applied and Integrated Safety in Germany have published a paper detailing how to compromise a virtual machine encrypted by AMD's Secure Encrypted Virtualization (SEV).The news is a bit of a downer for AMD, since it just added Cisco to its list of customers for the EPYC processor. Cisco announced today plans to use EPYC in its density-optimized Cisco UCS C4200 Series Rack Server Chassis and the Cisco UCS C125 M5 Rack Server Node.To read this article in full, please click here

IDG Contributor Network: Compelling ways the C-level can leverage the IoT

Across a variety of industries, corporate IT and operations teams are rapidly deploying IoT to meet core business objectives. The aim of these deployments can vary greatly, from monitoring device health, to reducing operating costs, and increasing production volume. Yet there are a number of other areas throughout an organization, with initiatives of equal importance, where stakeholders have yet to leverage the value of connected device data to achieve their goals. One such example is the C-level. While generally not designed with executives in mind, IoT technology can provide value to the C-level that’s on par with the advantages their IT and operations counterparts stand to gain.To read this article in full, please click here

IDG Contributor Network: Houston, we have a networking problem

We’ve covered networking on our home planet. But what happens when we send signals where no man has gone before?Space networking is two-way communication between base stations on Earth, and unmanned space probes, planetary rovers, orbital satellites or manned spacecraft. These radio signals bring back messages, images and scientific discoveries. Someday they’ll be used to communicate between colonies on Earth and the moon or Mars.Of course, we can’t just “call” Mars. Networking in outer space is vastly different from what we experience on Earth.Communications travel at the speed of light. This means that it can take 20 minutes or more for a radio signal to reach a Martian planetary rover. It’s like going back to dial-up.To read this article in full, please click here

BrandPost: The Next SDN Leap: Automation and Intent-Driven Networking

Without an agile, flexible, and secure network infrastructure, organizations are in danger of falling behind competitors. That’s why many organizations are seeking to transform their businesses with cloud computing and hybrid cloud environments that are more adaptive and flexible. Software-defined networks (SDN) and network functions virtualization (NFV) can ease that path, but it requires automation along with intelligence that understands and can even predict what users and organizations want and need to do.Digital transformation has quickly moved beyond hype to become one of the top business imperatives. “Digital transformation is forcing companies to be agile and move with speed, and the network needs to be equally agile and fast,” writes industry analyst Zeus Kerravala. “The separation of control and data planes enables control to be abstracted away from the device and centralized so a network administrator can issue a change that is propagated instantly across the entire network.”To read this article in full, please click here

IDG Contributor Network: Internet testing results: why fixing the internet middle mile is essential for SD-WAN performance

It’s no secret that the public Internet is a quagmire of latency and packet loss problems. No wonder, many of clients are reluctant to trust Internet-based SD-WANs with VoIP and business-critical applications. After all, how can an SD-WAN running over Internet provide a predictable user experience if the underlying transport is so unpredictable?To answer that question, SD-WAN Experts recently evaluated the performance and stability of long-distance Internet connections. Our goal: to determine the source of the Internet's performance problems by measuring variability and latency in the last and middle miles.What we found was by swapping out the Internet core for a managed middle mile makes an enormous difference. Case in point is Amazon. The latency and variation between our AWS workloads was significantly better across Amazon’s network than the public Internet (see figure). Why that’s the case and how we tested is explained below and in greater depth from this post on our site.To read this article in full, please click here

Building IoT-ready networks must become a priority

The Internet of Things (IoT) era has arrived, and over the next few years, billions of devices will be connected to company networks. How many? ZK Research has forecast that by 2022, there will be 80 billion connected devices. (Note: I am an employee of ZK Research.) ZK Research Given many network managers struggle running today's networks, adding orders of magnitude more devices certainly won’t make life better. Even if it seems IoT may be a few years off, it’s critical that network professionals start prepping their network now.To read this article in full, please click here

The future of storage is here

Sometime in the past couple of years, Gartner introduced a term called “Shared Accelerated Storage” (SAS) to describe what’s next for the industry after all-flash arrays. I’m not sure when they first used the term, but it was the very first bullet in its 2017 Storage Hype Cycle, indicating its relative newness as a market category.In its Hype Cycle, Gartner has a rather long and complicated definition of what SAS is. The easy way to think about it is that it brings the benefits of network-based systems and direct-attached systems together by leveraging a number of new technologies, most notably Nonvolatile Memory Express— or NVMe, as its more commonly known.  To read this article in full, please click here
