Few, if any, industries escaped the effects of the COVID-19 pandemic. Even in the technology sector, where change is a normal part of business, many professional services and technology consulting firms struggled to cope with the disruption. That seems almost paradoxical given that organizations across just about every market sector had to embrace work-from-home operations […]

Almost all Wi-Fi is potentially vulnerable to flaws that date back to 1997 when it became commercially available, but even the person who discovered the weaknesses says some of them are difficult to exploit.
Mathy Vanhoef, a post-doctoral student at NYU Abu Dhabi, has created attacks—FragAttacks—that take advantage of the vulnerabilities, but in an academic paper about them, says the most widespread vulnerabilities can be exploited only under specific, rare conditions, and require either user interaction or highly unusual configurations to succeed.
The world stands on the brink of the fourth industrial revolution – the confluence of new technologies like cloud computing, big data analytics, and IoT have reached a tipping point where enterprises can successfully process workloads in the cloud like never before.
Indeed, 85% of enterprises will have deployed new digital infrastructure in the cloud by 2025, according to industry analyst IDC. In the US, the cloud migration rate of enterprises has exceeded 85% and in EU countries has reached 70%.
Governments are a key catalyst for this change, as they push whole economies to digitize to improve whole of society benefits and increase national productivity.
IDC research suggests that there will be more than 50 billion Internet-connected devices by 2025: 14 billion non-IoT devices and another 41 billion connected IoT devices. In addition to that, enterprises are relying on Internet-connected services more than ever; 80% of new revenue will come from digital services by next year, and those digital services will be delivered over complex cloud environments.
And yet, also according to IDC, 62% of enterprise IT leaders reported that they were only “somewhat satisfied” with the performance of their Wi-Fi environment, indicating that there is a lot of room for businesses to upgrade their Internet environments to take full advantage of the opportunities that these connected devices and cloud services provide.

For anyone who has lived in a dense apartment complex or building, multiple Wi-Fi routers close together competing for limited radio signal space can make accessing the Internet a challenging experience, to say the least. To address the problem, property managers are increasingly treating Wi-Fi as a fifth utility for large multifamily communities, not only to create a better overall online experience for residents but also to leverage a single network to better enable and implement smart home features designed to improve the convenience and comfort of tenants.
AMD saw another quarter of outstanding growth in sales of its server chips, giving the company its highest single-quarter gain for server CPUs since 2006 and eating into Intel’s most valuable market segment, according to the latest market report from Mercury Research.
We’ll get to the desktop segment later, but AMD’s server CPU share grew 1.8 percentage points from Q4 2020 to Q1 2021, from 7.1% to 8.9%. That is astonishing as server numbers just don’t move like that so quickly. In the same single-quarter period, Intel slipped 1.8 percentage points, from 92.9% to 91.1%.
There is seasonality in the server market, where it is normal for sales to go down in Q1, Dean McCarron, president of Mercury Research, told me. Cloud-server companies like AWS and Google go through a build/burn cycle where they buy a lot, then take time to deploy it all. Right now we are at the very bottom of build cycle where they buy the least amount, so if they are putting up these kinds of numbers during a low point, it will be even better when they start buying again.
VMware says its COO for products and cloud services, Raghu Raghuram, will be its next permanent CEO, a signal that the company’s board intends to keep VMware on its present course.
When Raghuram takes the reins in June, it will end a four-month interregnum, during which the company has been helmed by CFO Zane Rowe. Former CEO Pat Gelsinger became the CEO at Intel in February, returning to the company where he had worked for 30 years.
VMware is the unquestioned 800-pound gorilla of the enterprise hypervisor market and has pursued both internal technology development and a succession of strategic acquisitions to diversify its business. The company’s hypervisor business, buttressed by deals with AWS, Azure, Google Cloud and other hyperscalers to provide its core products as cloud services, is still the main revenue stream. But VMware also plays in security, containerization, and cloud-native applications.
A flurry of announcements from hardware vendors points to a change in how enterprises are purchasing servers, storage and networking resources for their data centers and edge deployments.
To entice companies to keep workloads on premises, hardware vendors including Cisco, Dell, HPE, IBM, Lenovo and others are offering consumption-based pricing for data-center infrastructure. These pay-per-use products are designed to shorten procurement cycles, allow customers to scale up or down with demand, and more economically link hardware spending with usage.
HPE, for example, pledged to transform its entire portfolio to pay-per-use and as-a-service offerings by 2022, and last week, the company added to its GreenLake lineup with new data services and infrastructure. Dell, for its part, unveiled the first products in its Apex portfolio of managed storage, servers, and hyperconverged infrastructure.
Overall U.S. employment figures for April may have been dismal but not in the tech sector, which has grown steadily all year, adding 16,000 new jobs in April for a total of 60,900 so far this year.
That’s according to CompTIA‘s analysis of the U.S. Bureau of Labor Statistics’ (BLS) latest Employment Situation Summary. The overall jobs numbers, which came out last week, were dismal. The U.S. created just 266,000 new jobs in April when economists surveyed by Dow Jones and The Wall Street Journal had estimated 1 million new jobs.
However, there are signs of tech hiring slowing. Employers across all sectors of the economy reduced their hiring of IT workers by an estimated 234,000 positions. This was the first decline after four consecutive months of employment gains. For the year, IT hires have increased by 72,000 positions.
Linux commands offer a lot of flexibility. This post details some ways to make them even more convenient to use by making use of some clever tricks.
Using file-name completion
You can avoid typing a full file name by typing the beginning of its name and pressing the tab key. If the string uniquely identifies a file, doing this will complete the filename. Otherwise, you can enter another letter in the name and press tab again. However, you can also get a list of all files that begin with a particular string by typing the string and then hitting the tab key twice. In this example, we do both:
$ ls di<tab><tab> diff-commands dig.1 directory dig.2 dimensions disk-usage-commands $ cd dir<tab> $ pwd directory
Reusing commands and changing them
Reissuing recently used commands is easy in bash. To rerun the previous command, all you have to do it type !! on the command line. You can also reissue a command with changes. If you issued the first command shown below only to find that sshd wasn't running, you could issue the second command to start it. It simply replaces "status" with "start".
As TSMC charges to 5nm transistor designs and Intel struggles for 7nm, IBM has topped them all with the world’s first 2-nanometer node chip.
OK, it won’t come to market for four years, according to IBM, and they might not be the first name that comes to mind when you think of processor design, but they are the quiet power in the semiconductor world.
As far as commercial chips go, IBM makes two: the Power series for its Power line of Unix and Linux servers, and zArchitecture that is used in the z Series of mainframes. But IBM has its IBM Joint Development Alliance which is partnered with just about every semiconductor vendor out there—Intel, AMD, Nvidia, TSMC, Samsung, you name it.
As the enterprise edge expands to include semi-permanent remote workforces, IoT, and a range of applications like AI and M2M, they generate torrents of nonstop data that must be stored indefinitely and be available in near-real-time to users and applications.
Legacy storage architectures are failing to keep up with both data growth and user/application demand. While storage innovation is pushing more workloads into the cloud, many startups have found that the average enterprise is not yet ready for cloud-only storage. Legacy architectures and applications are experiencing extended shelf-lives due to tight IT budgets, and many enterprises still prefer to keep certain workloads on-premises.
The reliability of services delivered by ISPs, cloud providers and conferencing services (a.k.a. unified communications-as-a-service (UCaaS)) is an indication of how well served businesses are via the internet.
ThousandEyes is monitoring how these providers are handling the performance challenges they face. It will provide Network World a roundup of interesting events of the week in the delivery of these services, and Network World will provide a summary here. Stop back next week for another update, and see more details here.
I can’t tell you how many times one of my clients or contacts has complained about the difficulties associated with getting network-budget approval. If I’d never met a CFO in person, the description these people gave me would have led me to expect something like a troll or a zombie, bent on eating projects and maybe people, too. Do we wear garlic when we visit the CFO, or maybe do a chant before the meeting, or might there be a more practical approach?
CFOs aren’t just trying to mess up a good technology project (at least most of the time), they’re trying to validate two basic financial rules that govern technology procurements. Rule One is that any project must advance a company’s financial position and not hurt it. That seems logical, but it’s often difficult to assess just what the return on investment (ROI) of any project is. Rule Two is that you don’t want to buy equipment that you’ll have to replace before it’s been fully depreciated. The useful life of something should be at least as long as the financial life as set by tax laws.
A UK-based AI-chip startup is making its first moves into North American to take on Nvidia on its home turf in the enterprise with new channel and reseller partners.
Founded in 2016, Graphcore makes what it calls Intelligence Processing Units (IPUs) and shipped its first product—the Colossus GC2 “massively parallel, mixed-precision floating point processor”—in 2018. In July 2020, it released its second-generation processor called GC200, but news of that was drowned out by all the disruption caused by COVID-19.
In addition to chips, the company sells cards and racks. The IPU-M2000 is a 1U blade built around four Colossus GC200 IPU processors, capable of one petaFlop of AI compute. The IPU-POD64 is designed for large-scale deployments and offers the ability to run very large models across as many as 64 IPU processors in parallel.
Certificate-based authentication is a cryptographic technique that allows one computer to securely identify itself to another across a network connection, using a document called a public-key certificate.
A lot of the value built into Windows Admin Center has to do with it being a remote-management tool that can have a lot of upside in a modern IT shop, including implementing best practices by not logging directly into servers, bringing flexibility to the management architecture, and performing admin tasks from high-DPI or touchscreen devices.
Considered a complement to System Center, Admin Center is a free app, downloadable here, that runs in a browser and can manage Windows Server 2019, Windows Server 2016, Windows Server 2012 R2, Windows Server 2012, Windows 10, Azure Stack HCI through Windows Admin Center Gateway, software installed on Windows Server or domain-joined Windows 10.
IBM continues to tweak its venerable mainframe to keep the Big Iron among the talking points in hybrid cloud.
About a year ago the company changed its 20-year mainframe software pricing scheme to make it more palatable to hybrid cloud and multicloud users who might be thinking of moving workloads off the mainframe and into the cloud.
IBM has taken the wraps off a version of its Cloud Pak for Security that aims to help customers looking to deploy zero-trust security facilities for enterprise resource protection.
IBM Cloud Paks are bundles of Red Hat’s Kubernetes-based OpenShift Container Platform along with Red Hat Linux and a variety of connecting technologies to let enterprise customers deploy and manage containers on their choice of private or public infrastructure, including AWS, Microsoft Azure, Google Cloud Platform, Alibaba and IBM Cloud.
Juniper Networks has laid a key part of its Secure Access Services Edge (SASE) foundation with a cloud-based security-control service that provides a central way to control and protect on-premises or cloud-based enterprise resources.
Called Security Director Cloud, the service focuses Juniper's SASE efforts by providing a central point to manage enterprise security services including policy setting, and threat-detection and -prevention.
Juniper (like other key enterprise networking vendors such as Cisco, Hewlitt-Packard Enterprise (Aruba) and VMware, as well as service providers including Cato Networks, Akamai, and Zscaler) has pledged allegiance to growing SASE support in its product families.
Used frequently, bash aliases can make working on the Linux command line a lot smoother and easier, but they can also be complicated and hard to remember. This post examines how you might make your aliases work for you rather than vice versa.
In general, aliases are especially good for:
- simplifying commands that are long and overly complex
- remembering commands with odd or complicated names
- saving time using commands that you use very often
What you need to keep in mind is that:
- aliases can themselves be hard to remember
- giving an alias the same name as a regular command can be a good thing or a bad thing (more on this shortly)
How to create an alias
Use the alias command and remember to add it to your ~/.bashrc file so that it will still be waiting for you whenever you login.
You know Google has more money than it could ever spend when it invests in a custom chip to do one task. And now they’ve done it for the third time.
The search giant has developed a new chip and deployed it in its data centers to compress video content. The chips, called Video (Trans)Coding Units, or VCUs, do that faster and more efficiently than traditional CPUs.
In a blog post discussing the project, Jeff Calow, a lead software engineer at Google said the VCU gives the highest YouTube video quality possible on your device while consuming less bandwidth than before.
Dell is launching a new offering of managed storage, server, and hyperconverged infrastructure that can be deployed in a company's own data center, at edge locations or in colocation facilities, and enterprises pay for capacity as needed.
Dubbed Dell Apex, it includes storage, cloud services, and a console for streamlined management. The launch coincides with the kickoff of Dell Technologies World 2021, which is being held virtually this year.
Pay-per-use hardware models such as Dell Apex and HPE GreenLake are designed to deliver cloud-like pricing structures and flexible capacity to private data centers. The concept of pay-per-use hardware isn't new, but the buzz around it is growing. Enterprises are looking for alternatives to buying equipment outright for workloads that aren't a fit for public cloud environments.
Hewlett Packard Enterprise took a big step toward delivering on its “entire-portfolio-as-a-service” strategy this week by unveiling cloud-based storage and data service that will help manage storage needs in distributed IT enterpises.
HPE said in 2019 that by 2022 it wanted to remake itself into a more service-oriented company and announced plans to transition its entire portfolio to subscription based, pay-per-use, and as-a-service offerings. It has since made headway, for example, recently adding HPE GreenLake cloud services for HPC.
Cisco has taken the wraps off a technology package it says will utilize existing core wireless and wired systems to help enterprises better control their physical environments and enable a safer, more secure return to the office.
While supporting remote offices and branches of one—IDC says that post-COVID, more than 52% of workers will either remain remote or hybrid—they rest could return to an altered business space.
In these offices, sensors and devices that have been used to manage lighting and HVAC systems can be adapted to occupancy and density monitoring, air-quality testing, contact tracing, and in-room presence, according to Anoop Vetteth, vice president of product management with Cisco’s Enterprise Switching and Software Solutions group.
The perfect WAN?
Network technology is constantly evolving. You have more choices than ever when evaluating how to connect your offices, locations, data centers, and remote users.
One of the keys to deploying an optimal Wide Area Network (WAN) that uniquely fits your business is understanding the vast array of underlay and overlay options. Underlay offers connection or transport types such as Multiprotocol Label Switching (MPLS), internet, dedicated internet, fiber, and wireless broadband. Overlay options include Edge devices such as traditional IP routers, software based white boxes, and the vast array of software-defined WAN (SD-WAN) appliances.
The days are long past when a fast office Wi-Fi connection was a nice-to-have. These days it's essential for your business to provide clients and employees alike with a speedy, reliable wireless network.
Proper site surveying and maintenance are crucial for wireless networks, and especially so for networks with heavy traffic, such as Wi-Fi hotspots at public venues. The same is true when speed is vital, as when streaming video or voice over Wi-Fi.
Fresh off one of the strongest quarters in the company’s 25 year history where it hit double-digit, year-over-year revenue growth and a fourth consecutive quarter of growth, Extreme Networks is betting heavily on automation, AI and cloud management to keep the party going.
The National Science Foundation (NSF) is not inclined to wait for next-generation (NextG) networks. And who can blame it? NextG promises faster cellular, Wi-Fi, and satellite networks, all of which can be used to enhance data streaming, wireless communications, analytics, and automation.
For the NSF, this translates into improved national defense, education, public health and safety, transportation, and digital infrastructure. For enterprises, NextG means greater efficiency, flexibility, business insights, and more opportunities to replace human workers with robots. (I’m just sayin’.)
IT teams are dealing with rapid technology changes with increased retraining and skill development, according to a report by trade association CompTIA.
Seven in 10 HR professionals surveyed who work with IT personnel said they plan a substantially increased effort to help workers re-skill in the coming year, with larger firms reporting a particularly strong emphasis in that area. Nearly 80% of IT HR professionals employed at such companies rated re-skilling or up-skilling as “more important” for the coming year, in contrast to 68% at medium-sized firms and 52% at smaller businesses.
These numbers mark a changed relationship between employers and tech, according to CompTIA director of education and ed tech Stephanie Morgan, adding that the pandemic helped force companies to rethink the way they deal with their workers. “Businesses have realized they have to talk about people like they’re people, not like they’re assets,” she said.
