Edge computing is shaping up as the most practical way to manage the growing volume of data being generated by remote sources such as IoT and 5G devices.A key benefit of edge computing is that it provides greater computation, network access, and storage capabilities closer to the source of the data, allowing organizations to reduce latency. As a result, enterprise are embracing the model: Gartner estimates that 50% of enterprise data will be generated at the edge by 2023, and PricewaterhouseCoopers predicts the global market for edge data centers will reach $13.5 billion in 2024, up from $4 billion in 2017.

Enterprise software is likely to have the highest growth in 2022 at 11.5%, driven by infrastructure software spending. Global spending on devices grew over 15% as remote work, telehealth and remote learning took hold, and Gartner expects 2022 will continue that growth as enterprises upgrade devices and/or invest in multiple devices to support the hybrid work setting. “Enterprises will increasingly build new technologies and software, rather than buy and implement them, leading to overall slower spending levels in 2022 compared to 2021,” said John-David Lovelock, distinguished research vice president at Gartner.To read this article in full, please click here

The maximum transmission unit (MTU) is the largest number of bytes an individual datagram can have without either being fragmented into smaller datagrams or being dropped along the path between its source and its destination.For Ethernet frames—and many other types of packets—that number is 1500 bytes, and it generally meets the requirements of traffic that can cross the public internet intact.[Get regularly scheduled insights by signing up for Network World newsletters.]
So, if 2000-byte Ethernet packets arrive at a router, it will split their payloads in two and repackage them into two packets that are each smaller than 1500 bytes and so meet the MTU.To read this article in full, please click here
The xargs command on Linux can make it easier to build and execute commands. If you want to run the same command for a group of files or users, xargs can often make that process easier. Here's a very simple example of xargs that creates or updates the update time on some files.$ echo file1 file2 file3 | xargs touch
$ ls -l
total 0
-rw-r--r--. 1 shs shs 0 Oct 15 12:41 file1
-rw-r--r--. 1 shs shs 0 Oct 15 12:41 file2
-rw-r--r--. 1 shs shs 0 Oct 15 12:41 file3
The command below is similar, but creates a file with blanks in its name because the -d specifies the input termination character.To read this article in full, please click here
A new auction for enormously valuable mid-band spectrum and a rollback of availability for a different piece of it illustrates the uneven progress of 5G rollouts in the U.S. and represents a challenge for enterprises looking to take advantage of 5G technology.
5G resources
What is 5G? Fast wireless technology for enterprises and phones
How 5G frequency affects range and speed
Private 5G can solve some problems that Wi-Fi can’t
Private 5G keeps Whirlpool driverless vehicles rolling
5G can make for cost-effective private backhaul
CBRS can bring private 5G to enterprises
The mid-band is valuable because it’s in a “Goldilocks” zone of the wireless spectrum—its frequencies are high enough to support higher throughput, while also being low enough to propagate effectively across relatively large areas.To read this article in full, please click here

Microsoft has just made the Windows Subsystem for Linux (WSL) available in the Microsoft Store for Windows 11 systems. WSL is the application that allows Windows users to run a GNU/Linux environment directly on Windows without the overhead of a virtual machine or dual-boot setup.One good aspect is that it installs as a separate app, decoupled from the OS. This means that users can update the app without having to wait for Windows OS updates to become available.Summarizing your command-line usage on Linux
The app in the Microsoft Store is not a new version of WSL. It’s still WSL 2, but is a preview version that was added as an option for end users to get the latest features faster and more conveniently. The binaries will no longer be part of the Windows image.To read this article in full, please click here
Marvell has begun to sample the Octeon 10, a server microprocessor aimed at intelligent network management that has up to 24 Arm-compatible cores, making it as powerful as any server processor.Marvell refers to the Octeon processor line as data processing units (DPUs). They are designed to run high-throughput data in the cloud and on-premises. The DPU is more commonly called the SmartNIC because it can offload non-computational tasks from the CPU like network packet processing, data encryption and compression. That frees up CPU cores to run general-purpose applications.The Octeon 10 has a few firsts. It's the first processor made by TSMCs 5nm manufacturing process and the first processor to feature Arm’s Neoverse N2 core. The N2 core uses the new Armv9 architecture that the company claims can deliver 40% more single-threaded performance for a variety of workloads vs. the N1, but still retains the same level of power and area efficiency as N1.To read this article in full, please click here
The third-placed cloud vendor has announced a new set of options for customers that need to keep certain workloads in self-hosted environments or out at the edge.
VMware is in the process of spinning out from Dell Technologies, but the working relationship remains as strong as ever with a bunch of announcements from VMworld.All told, the pair made four significant announcements at the show, the first being that VMware Cloud will be sold on systems acquired through Dell's Apex pay-as-you-go program. The new Apex offering gives customers the ability to move workloads across multiple cloud environments and scale resources quickly with predictable pricing and costs.The new offering combines Dell’s hyperconverged infrastructure VxRail with VMware Cloud, VMware Tanzu for building cloud-native applications, and VMware HCX for application migration. Businesses can deploy the offering in their data center, at an edge location or a colocation facility with partners like Equinix.To read this article in full, please click here
You have to hand it to Larry Ellison, he is persistent. Or maybe he just doesn’t know when to give up. Either way, Oracle has shipped the latest in its Exadata server appliances, making some pronounced boosts in performance.Exadata was the old Sun Microsystems hardware Oracle inherited when it bought Sun in 2010. It has since discontinued Sun’s SPARC processor but soldiered on with servers running x86-based processors, all of them Intel despite AMD’s surging acceptance in the enterprise.When Oracle bought Sun in 2010, it was made clear they had no interest in low-end, mass market servers. In that regard, the Oracle Exadata X9M platforms deliver. The new Exadata X9M offerings, designed entirely around Oracle’s database software, include Oracle Exadata Database Machine X9M and Exadata Cloud@Customer X9M, which Oracle says is the only platform that runs Oracle Autonomous Database in customer data centers.To read this article in full, please click here
As technology extends deeper into every aspect of business, the tip of the spear is often some device at the outer edge of the network, whether a connected industrial controller, a soil moisture sensor, a smartphone, or a security cam.This ballooning internet of things is already collecting petabytes of data, some of it processed for analysis and some of it immediately actionable. So an architectural problem arises: You don’t want to connect all those devices and stream all that data directly to some centralized cloud or company data center. The latency and data transfer costs are too high.That’s where edge computing comes in. It provides the “intermediating infrastructure and critical services between core datacenters and intelligent endpoints,” as the research firm IDC puts it. In other words, edge computing provides a vital layer of compute and storage physically close to IoT endpoints, so that control devices can respond with low latency – and edge analytics processing can reduce the amount of data that needs to be transferred to the core.To read this article in full, please click here
Edge computing is gaining steam as an enterprise IT strategy with organizations looking to push storage and analytics closer to where data is gathered, as in IoT networks. But it’s got its challenges.
