VMware licensing increase draws ire but is a logical move

VMware is increasing its CPU licensing prices for customers running CPUs with more than 32 physical cores. Effective April 2, if CPUs with more than 32 cores are deployed, then customers need to purchase additional CPU licenses.Such a change doesn't seem surprising. For the longest time, 32-core processors seemed like a pipe dream. Intel was hovering in the range of 20-odd cores, and AMD was a non-player. Then came the AMD Epyc with 32 cores in 2017, followed by Epyc 2 with 64 cores in 2019 . READ MORE: VMware’s ongoing reinventionTo read this article in full, please click here

VMware sees executive churn amid small layoffs

VMware is going through an annual ritual it calls “workforce rebalancing,” which has resulted in a few hundred employees being let go including with four senior executives, which might be concerning as executive churn is often a sign of trouble.On Jan. 25, the California Employment Development Department disclosed that VMware had cut 159 people in the Palo Alto office earlier in January. For a company of more than 22,000, that’s nothing, although there were likely cuts in other offices around the world as well.[Get regularly scheduled insights by signing up for Network World newsletters.] “We can confirm that there have been a limited number of changes to our workforce this month,” a VMware spokesperson said via email. “This is a part of regular workforce rebalancing that ensures resources across VMware’s global businesses and geographies are aligned with strategic objectives and customer needs. We have an active employee support program to ensure, where possible, impacted employees will be redeployed to open roles within VMware. We continue to recruit in areas of strategic importance for the company.To read this article in full, please click here

Top 10 underused SD-WAN features

Early SD-WAN products provided enterprises with a way to decommission expensive, inflexible MPLS links, connect branch offices directly to the cloud and optimize WAN traffic. But many of the initial SD-WAN offerings lacked features such as integrated firewalls, application-aware routing, and advanced data analytics.Over time, SD-WAN vendors have beefed up their products to encompass a robust set of additional features. However, many enterprises are not taking advantage of the full capabilities of the latest SD-WAN products and managed service options.

How bacteria could run the Internet of Things

Biologically created computing devices could one day be as commonplace as today’s microprocessors and microchips, some scientists believe. Consider DNA, the carrier of genetic information and the principal component of chromosomes; it's showing promise as a data storage medium.A recent study (PDF) suggests taking matters further and using microbes to network and communicate at nanoscale. The potential is highly attractive for the Internet of Things (IoT), where concealability and unobtrusiveness may be needed for the technology to become completely ubiquitous.To read this article in full, please click here

Intel denies reports of Xeon shortage

Intel has denied reports that its Xeon supply chain is suffering the same constraints as its PC desktop/laptop business. CEO Bob Swan said during the company's recent earnings call that its inventory was depleted but customers are getting orders.The issue blew up last week when HPE – one of Intel's largest server OEM partners – reportedly told UK-based publication The Register that there were supply constraints with Cascade Lake processors, the most recent generation of Xeon Scalable processors, and urged HPE customers "to consider alternative processors." HPE did not clarify if it meant Xeon processors other than Cascade Lake or AMD Epyc processors.To read this article in full, please click here

BrandPost: Scaling Secure SD-WAN Across Hundreds of Branch Offices

Digital Innovation at the Branch Requires SD-WAN Most organizations with multiple locations are in the process of implementing a distributed networking strategy that ensure that all branch offices and users are able to take advantage of ongoing digital innovation efforts. For true cross-organizational collaboration, productivity enhancement, and improved user experience, every user needs access to essential business applications. To achieve this, they need highly flexible and scalable access to cloud-based applications and resources, direct access to the internet, and on-demand connections to other users and devices.That’s simply not possible with traditional hub-and-spoke branch networking models built around WAN routers and a fixed MPLS connection. Business applications, especially those that deliver rich media or enable highly flexible collaboration between users and locations – such as unified communications, Office 365, and similar tools – require massive amounts of bandwidth. And in a traditional model, all of that traffic needs to be backhauled through the core network. Multiply that by scores of remote workers located in dozens of remote offices and you can quickly overwhelm internal servers, compute resources, and even security and inspection tools.To read this article in full, please click here

Cisco helps IT and DevOps troubleshoot hybrid-cloud apps

Cisco has taken the wraps off of new tools it says will boost on-premises or cloud application performance by helping IT and devops work together to automate and more quickly resolve software problems.The new tools include a package from Cisco AppDynamics that lets customers track the key components users interact with as they use enterprise applications. Cisco paid $3.7 billion for AppDynamics three years ago for its application-performance monitoring and problem-resolution automation technology.  The idea was to develop products and applications that would give customers better end-to-end visibility of the IT infrastructure, including cloud, devices, security, network, compute and applications.To read this article in full, please click here

Hybrid-cloud management requires new tools, skills

Hybrid cloud environments can deliver an array of benefits, but in many enterprises, they're becoming increasingly complex and difficult to manage. To cope, adopters typically turn to some type of management software. What soon becomes apparent, however, is that hybrid cloud management tools can be as complex and confounding as the environments they're designed to support.A hybrid cloud typically includes a mix of computing, storage and other services. The environment is formed by a combination of on-premises infrastructure resources, private cloud services, and one or more public cloud offerings, such as Amazon Web Services (AWS) or Microsoft Azure, as well as orchestration among the various platforms.To read this article in full, please click here

Congress weighs in on additional Wi-Fi spectrum

A Congressional committee is weighing in on a spat between the FCC and parts of the automotive industry over a plan to appropriate a piece of wireless spectrum set aside for connected-cars and instead designate it for Wi-Fi.The dispute centers on Dedicated Short Range Communications or DSRC, a point-to-point communication standard designated to let vehicles close to each other on roadways share information to improve safety. The go-to example is using it to warn a driver near-instantly if the car ahead suddenly slams on its brakes.[Get regularly scheduled insights by signing up for Network World newsletters.] DSR and its 75MHz of spectrum in the 5.9GHz band has been a relatively obscure technology until late last year when the FCC started considering that 45MHz of that spectrum should be made available for unlicensed wireless use such as Wi-FiTo read this article in full, please click here

BrandPost: Huawei CloudCampus Triumphs over Cisco DNA, Tolly Reports

With new technologies such as automation and artificial intelligence (AI) emerging all around us, enterprise digitalization is inevitable. But however much enterprises want to transform, there is a significant cost in terms of time and technological manpower to ensure the system runs smoothly. In particular, enterprises are often faced with a variety of human factors that can hamper digitalization projects, including organizational resistance to change, lack of a clear vision, and inability to gather and leverage customer data, to name just a few.On the technical front, the challenge is in finding the right products and services to overcome the inflexibility of technology stack and development processes. Therefore, picking the most suitable and flexible solutions to meet the transformation challenges is usually the key to success. The right solution not only streamlines deployment but also makes it easier for people who are involved in the exercise – the easier the jobs, the less reluctant the organization towards the changes.To read this article in full, please click here

Setting up passwordless Linux logins using public/private keys

Setting up an account on a Linux system that allows you to log in or run commands remotely without a password isn’t all that hard, but there are some tedious details that you need to get right if you want it to work. In this post, we’re going to run through the process and then show a script that can help manage the details.Once set up, passwordless access is especially useful if you want to run ssh commands within a script, especially one that you might want to schedule to run automatically.It’s important to note that you do not have to be using the same user account on both systems. In fact, you can use your public key for a number of accounts on a system or for different accounts on multiple systems.To read this article in full, please click here
