Machine learning in network management has promise, challenges

As part of the trend toward more automation and intelligence in enterprise networks, artificial intelligence and machine learning are increasingly in-demand because the ability to programmatically identify problems with the network and provide instant diagnosis of complex problems is a powerful one.Applying AI and ML to network management can enable the consolidation of input from multiple management platforms for central analysis. Rather than IT staff manually combing through reports from diverse devices and applications, machine learning can make quick, automated diagnoses of problems.To read this article in full, please click here

Verizon deals with Microsoft, Nokia aim at making private 5G easier

Verizon’s recent announcements of new partnership deals with Microsoft and with Nokia are designed to create a unified platform for businesses to use as they build their own edge deployments, according to experts.Those deals will see Verizon offer Azure integration natively on its 5G Edge networking platform, as well as partnering for private 5G delivery with Nokia, with the latter agreement focusing on areas where Verizon does not already have a public networking presence, like Europe and Asia-Pacific. The company already has partnerships in place with AWS and IBM, among other major edge technology players.To read this article in full, please click here

Gartner crystal ball: Look to neuromorphic computing, DNA storage

Gartner is taking a swing at predicting future trends in IT, flagging neuromorphic computing and DNA storage technologies, and an expanded responsibility for CIOs to deliver digital-business outcomes.Future technologies are resetting everything as current technologies are being stressed to their limits, and conventional computing is hitting a wall,  Daryl Plummer, distinguished research vice president and Gartner fellow told the virtual audience at the firm’s IT Symposium/Xpo Americas.The industry is on a roller-coaster ride that will lead the "reset of everything," Plummer said. The future technologies Gartner forecasts will impact the industry the most have three key common threads: they promote greater innovation and efficiency in the enterprise; they are more effective than the technologies that they are replacing; and they have a transformational impact on society, Plummer said.To read this article in full, please click here

Dell launches Apex, a per-use hardware-leasing program

All of the major IT hardware suppliers to one degree or other have adopted a consumption model, which is a fancy word for leasing. Rather than the outright purchase of hardware, customers lease it, usage is monitored, and the customer pays a monthly use fee.Now Dell Technologies has announced it is expanding its as-a-service capabilities with Project APEX, to simplify how customers and partners access Dell technology on-demand.APEX will cover an array of Dell products —storage, servers, networking, hyperconverged infrastructure, PCs, and broader solutions. Project APEX will unify the company’s as-a-service and cloud strategies, technology offerings, and go-to-market efforts previously sold under the On Demand monicker.To read this article in full, please click here

Gartner: IT spending to grow 4% in 2021

Worldwide IT spending is forecast to reach $3.8 trillion in 2021, an increase of 4% from 2020, according to research firm Gartner, but still shy of pre-pandemic levels. IT spending in 2020 is expected to total $3.6 trillion, down 5.4% from 2019.Certain industries facing prolonged lockdowns due to COVID-19, such as entertainment and air transport, have cut IT spending by more than 30% in 2020, according to Gartner, which delivered the current outlook for the global IT market at its virtual IT Symposium/Xpo 2020 Americas.   Learn more:To read this article in full, please click here

Disowning a process in Linux

When you want a process to continue running even after you log off a Linux system, you have a couple options.One of them is to use the disown command. It tells your shell to refrain from sending a HUP (hangup) signal to the process when you log off. So, the process continues running. This can be very handy whenever you start a process and then, for some reason, you can’t stay logged in and wait until it finishes.[Get regularly scheduled insights by signing up for Network World newsletters.] The disown command is a shell built-in. This means that you don’t have to install it to use it, but it also means that it won’t be available if you use a shell that doesn’t support it. For those of us using bash and related shells (zsh, ksh etc.), disown should be available and you can verify this with a command like this that lists shell built-ins and then looks for "disown":To read this article in full, please click here

How to enforce password complexity on Linux

Deploying password-quality checking on your Debian-based Linux servers can help ensure that your users assign reasonably secure passwords to their accounts, but the settings themselves can be a bit misleading.For example, setting a minimum password length of 12 characters does not necessarily mean that all your users' passwords will actually have 12 or more characters.Let's stroll down Complexity Boulevard and see how the settings work and examine some that are worth considering.[Get regularly scheduled insights by signing up for Network World newsletters.] The files that contain the settings we're going to look at will be:To read this article in full, please click here

Backing up databases is critical and complex

Databases, also referred to as structured data, are an essential part of any data center. While databases do not typically hold a high percentage of the terabytes housed in a given data center, they do hold a high percentage of mission-critical data. Understanding their unique structure and operation is key to backing them up.Structured data cannot be backed up like unstructured data due to three very big challenges. First, databases are typically stored in datafiles that are constantly changing as long as something is making updates to the database. This means you cannot just back them up like any other file.To read this article in full, please click here

The OSI model explained and how to easily remember its 7 layers

The Open Systems Interconnect (OSI) model is a conceptual framework that describes networking or telecommunications systems as seven layers, each with its own function.The layers help network pros visualize what is going on within their networks and can help network managers narrow down problems (is it a physical issue or something with the application?), as well as computer programmers (when developing an application, which other layers does it need to work with?). Tech vendors selling new products will often refer to the OSI model to help customers understand which layer their products work with or whether it works “across the stack”. [ Related: What is IPv6, and why aren’t we there yet? ] The 7 layers of the OSI model The layers are: Layer 1—Physical; Layer 2—Data Link; Layer 3—Network; Layer 4—Transport; Layer 5—Session; Layer 6—Presentation; Layer 7—Application.To read this article in full, please click here

AMD introduces Zen 3 architecture and pursues Xilinx acquisition

AMD had a busy week last week. It introduced the third generation of its Zen microarchitecture, which has been propelling the company’s comeback since 2017, and is the subject of reports it is looking to buy field-programmagle gate array (FPGA) maker Xilinx.Five years ago, AMD was a non-entity in the CPU market and only kept afloat by its GPU business. Intel had written the company off and considered Qualcomm its biggest competitor. Then the company came out with Zen, a whole new design. “We started with Zen from scratch, starting from a clean sheet of paper,” said CEO Lisa Su in a video announcement.The result is a nice comeback for a company that had been written off five years ago. It has 5.8% of the server market share as of Q2, 19.2% of desktop and 19.9% of mobile, according to Mercury Research, which specializes in semiconductor market share. The server share may seem low, but two years ago it was at zero and server turnover is slower than desktop.To read this article in full, please click here

How networking pros can help make better IT buying decisions

IT purchasing teams have a dismal track record, in part because they face a number of roadblocks. Undue influence of a few team members who only check in occasionally. Failure to include a diversity of stakeholders. Paying too much attention to what vendors say about their own products. Not giving security its due.
