Networking Is Fast Enough

Without looking up the specs, can you tell me the PHY differences between Gigabit Ethernet and 10GbE? How about 40GbE and 800GbE? Other than the numbers being different do you know how things change? Do you honestly care? Likewise for Wi-Fi 6, 6E, and 7. Can you tell me how the spectrum changes affect you or why the QAM changes are so important? Or do you want those technologies simply because the numbers are bigger?

The more time I spend in the networking space the more I realize that we’ve come to a comfortable point with our technology. You could call it a wall but that provides negative connotations to things. Most of our end-user Ethernet connectivity is gigabit. Sure, there are the occasional 10GbE cards for desktop workstations that do lots of heavy lifting for video editing or more specialized workflows like medical imaging. The rest of the world has old fashioned 1000Mb connections based on 802.3z ratified in 1998.

Wireless is similar. You’re probably running on a Wi-Fi 5 (802.11ac) or Wi-Fi 6 (802.11ax) access point right now. If you’re running on 11ac you might even be connected using Wi-Fi 4 (802.11n) if you’re Continue reading

Heavy Networking 696: EVPN Fundamentals (And Some VXLAN) With Tony Bourke

EVPN/VXLAN is our topic on today's Heavy Networking. What is it? What’s it for? Should you deploy it? Since you’ve probably already got a network, how do you add EVPN to it? Do you need special hardware? How does EVPN impact your security design? And what are the fundamentals? Our guest with the answers is IT instructor Tony Bourke.

Generative AI dominates VMware Explore news

There were some cloud announcements this week at VMware Explore in Las Vegas, but AI was the star, as it has been at nearly every tech company lately. Vendors have been rushing to add generative AI to their platforms, and VMware is no exception.The biggest AI features to emerge from the conference – VMware Private AI Foundation and Intelligent Assist – won't be fully available for months. VMware Private AI Foundation is a joint development with Nvidia that will enable enterprises to customize models and run generative AI applications on their own infrastructure. Intelligent Assist is a family of generative AI-based solutions trained on VMware’s proprietary data to automate IT tasks.To read this article in full, please click here

What shortage? Nvidia blows past expectations in second quarter

Nvidia exceeded all expectations for its second fiscal quarter of 2024 with revenue of $13.51 billion, a 101% jump from the same quarter last year. Net income came in at $6.74 billion, or $2.48 per diluted share, which is up 854% from a year ago and up 202% from the previous quarter.Analysts had expected revenue to come in at $11.04 billion with earnings per share totaling $2.07, according to data from Bloomberg.And it’s all thanks for enterprise sales. Last quarter, enterprise sales accounted for 60% of total revenue. This quarter, $10.3 billion of the $13.5 billion in total revenue – 76% – came from data center sales.“A new computing era has begun. Companies worldwide are transitioning from general-purpose to accelerated computing and generative AI,” said Jensen Huang, founder and CEO of Nvidia, in a statement. “Nvidia GPUs connected by our Mellanox networking and switch technologies and running our CUDA AI software stack make up the computing infrastructure of generative AI.”To read this article in full, please click here

Hedge 192: Addiction Recovery

Addiction and addiction recovery are not a “normal” Hedge topic, but addiction afflicts many people in Information Technology. We’re all “hard driven” types, who feel failure keenly, and we tend to spend more time working than is probably healthy for us. Brett Lovins has been through addiction and recovery, and joins Tom Ammon, Russ White, and Eyvonne Sharp to talk about this high impact topic.

Cisco, Kyndryl step up partnership to cut enterprise security threats

Cisco and Kyndryl have expanded their partnership to offer new services that are aimed at helping enterprise customers better detect and respond to cyber threats.Specifically, Kyndryl will be integrating its own cyber resiliency offering with Cisco’s overarching Security Cloud platform that includes security components such as Cisco’s Duo access control, extended detection and response features, and Multicloud Defense, which orchestrates security and policy across private and public clouds.Security Cloud operates as a layer on top of the infrastructure across a customer’s cloud services – including Azure, AWS, GCP and private data-center clouds – to protect core applications, Cisco said. It features a unified dashboard, support for flexible trust policies, and open APIs to encourage third-party integrators. By correlating data and employing artificial intelligence and machine learning, Cisco Security Cloud can detect and remediate threats quickly throughout an organization, Cisco says.To read this article in full, please click here

Carriers vs. aggregators: How to select the optimal mix of network transport providers

Enabled by SD-WAN, internet-first networking strategies are now the order of the day for wide-area connectivity and have been for some time. While MPLS used to be the de facto choice for enterprise-grade network transport, companies today are using internet-based transport technologies such as dedicated internet access, business broadband, cellular broadband as well as other niche network technologies like microwave.Best practices call for companies to work with multiple suppliers to get competitive prices, maximize service coverage, and secure better service delivery performance. But which suppliers should an enterprise select? How do you figure out the best fit for an enterprise’s needs, and what are some of the challenges and gotchas of a multi-supplier portfolio approach?To read this article in full, please click here

Star your favorite websites in the dashboard

Star your favorite websites in the dashboard

We’re excited to introduce starring, a new dashboard feature built to speed up your workflow. You can now “star” up to 10 of the websites and applications you have on Cloudflare for quicker access.

Star your websites or applications for more efficiency

We have heard from many of our users, particularly ones with tens to hundreds of websites and applications running on Cloudflare, about the need to “favorite” the ones they monitor or configure most often. For example, domains or subdomains that our users designate for development or staging may be accessed in the Cloudflare dashboard daily during a build, migration or a first-time configuration, but then rarely touched for months at a time; yet every time logging in, these users have had to go through multiple steps—searching and paging through results—to navigate to where they need to go. These users seek a more efficient workflow to get to their destination faster. Now, by starring your websites or applications, you can have easier access.

How to get started

Star a website or application

Today, you can star up to 10 items per account. Simply star a website or application you have added to Cloudflare from its Overview page. Once Continue reading

OpenELA group pushes for bug compatibility with RHEL

A dramatic disagreement in the enterprise Linux community has some distributions scrambling to keep their code compatible with Red Hat, as the acknowledged biggest player in the space cracks down on source code distribution.The core issue is the existence of several “downstream” Linux distributions based on Red Hat Enterprise Linux. Those distributions were historically based on CentOS, a free RHEL clone developed originally for the purposes of testing and development. The downstream distributions in question, however, are supported by companies like CIQ and Oracle – which sell support services for their “clones” of RHEL. This has led to a long-running tension between those companies and Red Hat, whose supporters argue that the downstream companies are simply repackaging Red Hat’s work for profit, while detractors say that Red Hat is violating the sprit – if not, technically, the law – of open source.To read this article in full, please click here
