BrandPost: Network Essentials: SD-WAN and Zero Trust

2:43
In the world of business, what is considered essential changes over time. Most businesses haven't used paper accounting ledgers, fax machines, or phone books for years, for example. And now, in many cases, office space isn't even essential. The move to remote work caused by the pandemic led many organizations to invest in modern networking and security technologies. And protecting digital assets is becoming increasingly urgent as security threats such as ransomware continue to escalate at the...

BrandPost: 5 Keys to Creating a Zero-Trust Security Foundation

15:49
By Jon Green, Vice President and Chief Security Technologist Recent high-profile attacks have disrupted global commerce across the world, bringing home the critical importance of maintaining a robust IT security program. The recent ransomware attacks on the Colonial Pipeline , the largest petroleum pipeline in the US, and meat supplier JBS , highlight the cascading, society-disrupting havoc these types of attacks can create.

Intel unveils new type of network accelerator chip

15.June
Intel on Monday expanded its network processor roadmap with the announcement of the Infrastructure Processing Unit (IPU). Think of it as the next step in the SmartNIC market, because Intel does. The announcement was made at the Six Five Summit 2021, where Navin Shenoy, the head of Intel's Data Center Group, announced its intention to create the new processor family specifically for cloud workloads. There has been a move toward dedicated networking chips, called SmartNICs, that offload the wor...

Cisco bolts together enterprise and industrial edge with new routers

15.June
Cisco has extended its family of Catalyst networking gear with routers designed to integrate remote, industrial-edge network resources. The new Catalyst 5G Industrial Router family includes three modular routers and a gateway that run Cisco's core operating system, IOS XE, and support a variety of network access technologies such as SD-WAN , Wi-Fi 6 , 5G, 4G, Private LTE, FirstNet and Wi-SUN.

BrandPost: Delivering the Highest Quality of Experience in a Multi-Cloud World

15.June
The global pandemic has accelerated enterprise IT teams’ desire to simplify the management of complex multi-cloud and edge environments and operate them holistically as a single WAN. It is also driving IT requirements for delivering the highest levels of application performance for all their cloud-hosted business applications, from any network in the emerging post-pandemic environment. This shift is intensifying the urgency to transform conventional data center and MPLS-centric and VPN-based ...

A startup makes IoT sensors, no batteries necessary

15.June
A startup founded by two MIT grads says that it can deploy self-powering sensors to handle low-intensity IoT tasks, eliminating the need for batteries or wired electrical supplies, adding a new level of flexibility to IoT deployments. Ben Calhoun and Dave Wentzloff are the founders of Everactive, an IoT-device manufacturing startup whose sensor modules can create their own power from a variety of sources, including indoor solar, thermal gradient differential, and vibrations. The sensors can m...

The great cloud computing surge

14.June
Driven in part by the pandemic, cloud computing adoption has reached new heights. These five articles take a close look at the implications.

IoT cloud services: How they stack up against DIY

14.June
Eager to cash in on the massive potential for IoT-based data storage and analytics, public-cloud vendors are diving headlong into the IoT market, offering enterprises everything from individual building blocks to fully managed services and every combination in between. The amount of data that is expected to be generated by IoT devices is staggering. IDC predicts that by 2025, there will be 55.9 billion connected devices worldwide, 75% of which will be connected to an IoT platform. IDC estimat...

NetApp makes big hybrid-cloud push

11.June
NetApp is making a major effort to support hybrid cloud with a batch of software announcements around storage products, converged infrastructure, and cloud-management services. The main news was the release of the latest version of its flagship ONTAP software, as well as updates to other products designed to help organizations build a better hybrid-cloud strategies. ONTAP is the operating system for NetApp’s FAS (hybrid flash-disk) and AFF (all-flash) storage arrays. The latest version, 9.9, ...

Rescuing a Linux system from near disaster

11.June
The more you know about how Linux works, the better you'll be able do some good troubleshooting when you run into a problem. In this post, we're going to dive into a problem that a contact of mine, Chris Husted, recently ran into and what he did to determine what was happening on his system, stop the problem in its tracks, and make sure that it was never going to happen again. Disaster strikes It all started when Chris' laptop reported that it was running out of disk space--specifically that ...

Sunlight aims at more efficient virtualization

10.June
Virtualization software is dated and does not take full advantage of modern hardware, making it extremely power-inefficient and forcing data centers to overprovision hardware to avoid poor performance. That’s the pitch of Sunlight, a virtualization -software vendor whose products take advantage of technologies that didn’t exist when Xen, KVM, VMware and Hyper-V were first developed. “The cloud infrastructure or virtualization stacks have been designed and built 15 to 20 years ago,” said Koste...

Cisco upgrades intent-based-networking performance, security, analytics

10.June
Cisco brought new features to its DNA Center network-control platform that promise to improve performance, management analytics and security for its enterprise network customers. The new software features integration of a ThousandEyes agent that bulks-up the platform’s network-intelligence monitoring, a two-fold increase in the number of clients the system can support, and improved security and operational capabilities. DNA Center is the heart of Cisco’s intent-based networking strategy and i...

New NVMe spec brings new support for hard drives

9.June
The new NVM Express 2.0 has been released and with it a surprise: The non-volatile memory express protocol—best known for handling SSD speeds—is now offering full-blown support for traditional hard-disk drives. This is quite unexpected because SSDs are orders of magnitude faster than traditional HDDs. The first flash-based SSDs used SATA/SAS physical interfaces borrowed from existing hard drive-based enterprise server/ storage systems. However, none of these interfaces and protocols were desi...

Why the cloud will never eat the data center

9.June
Sometimes it’s hard to see gradual changes in technology paradigms because they’re gradual. Sometimes it helps to play “Just suppose…” and see where it leads. So, just suppose that the cloud did what some radical thinkers say, and “absorbed the network”. That’s sure an exciting tag line, but is this even possible, and how might it come about? Companies are already committed to a virtual form of networking for their WAN services, based on VPN s or SD-WAN , rather than building their own WANs f...

What you can find out asking which, whereis and whatis in Linux

7.June
The which , whereis and whatis commands on a Linux system provide information about commands. They provide related but not identical information. In this post, we’ll check out the differences and provide a script for getting information that’s available from all three commands. We’ll also explore some sample commands for looking at secondary (i.e., not section 1) man pages. which The which command will show you the file-system location for a command’s executable. This is the file that is read...
