RHEL 8.5 caters to multicloud, predictive analytics, containerization
Red Hat has rolled out version 8.5 of its main-line branch of Red Hat Enterprise Linux (RHEL), which upgrades its support for containerization, predictive analytics, and multicloud.Red Hat Insight, the company’s predictive-analytics service—available through most RHEL subscriptions—now has more robust abilities in the areas of vulnerability identification, compliance, and remediation, the company said.Containerization is upgraded with RHEL 8.5 to make containerized applications easier to deploy and manage, according to Red Hat. The company introduced the ability to create containerized images faster through rootless use of the OverlayFS filesystem. OverlayFS is “union file system,” which allows users to overlay one file system over another, enabling multiple users or applications to access it at the same time.To read this article in full, please click here

A $1.9B FCC fund to replace banned 5G telco gear might be too little
The Federal Communications Commission has opened up a $1.9 billion fund to help smaller, rural US telcos replace the 5G and other gear in their networks that is made by China-based Huawei and ZTE, whose equipment has been banned since the telecom providers bought it.The Secure and Trusted Communications Networks Reimbursement Program will help service providers remove, replace, and dispose of the equipment, but it's not likely to cover all their costs. “It’s hard to say what the gap is, but what I’m hearing from the rural wireless carriers and the others impacted by this, it won’t be enough,” said IDC research manager Patrick Filkins.The fund is open only to carriers with 10 million or fewer subscribers, and that means mostly rural providers who were attracted to the Chinese companies at least in part because of their less expensive product lines.To read this article in full, please click here

Red Hat Enterprise Linux 9 drops in beta version
Red Hat Enterprise Linux version 9 released today as a beta, bringing about a dozen major new features focused on security and compliance, simplified management and automation. But the biggest news might be the lack of changes to the management and administration tools from the previous version, which could make adoption fairly painless.The key new management features include enhanced web-console performance metrics for easier diagnosis of problems, live kernel patching without the need for downtime, and an easier way to create new OS images.[Get regularly scheduled insights by signing up for Network World newsletters.] Many of those features make RHEL 9 better-suited to use in edge environments, according to IDC vice president Dave McCarthy, who noted that automation seemed to be a particularly important focus in the new version.To read this article in full, please click here

Gartner: SD-WAN, SASE biggest drivers of WAN edge infrastructure
The past several years have seen a large-scale shift from traditional MPLS-based customer edge routers to SD-WAN technology, according to Gartner’s 2021 Magic Quadrant for WAN Edge Infrastructure. Overall spending on WAN edge will grow by 2.6% per year through 2025, according to the report. The increased sales of WAN edge technology in general is driven by SD-WAN equipment designed to support work-from-home and in-office environments are slightly dampened by the fact that sales of traditional branch office routers are sharply down as a consequence, Gartner says. As the world shifts from working from home to working from anywhere, companies have begun to shift away from the VPN as the main tool for keeping remote workers secure, and towards more-fully featured SD-WAN technologies, with the idea of eventually implementing zero-trust network access for maximal security, Gartner’s report noted.To read this article in full, please click here

Report: The chip shortage’s next victim is data-center switching
Enterprise looking to buy data-center switches face longer lead times and lack of stock over the course of the next year or so as demand continues to substantially outpace supply, according to a report from the Dell’Oro Group.Sameh Boujelbene, leader of the analyst firm’s campus and data-center research team, said that one canary in the coal mine was Broadcom’s announcement earlier this year that 90% of its total chip output for 2021 had been spoken for as early as March. That’s the result not just of material shortages that have affected the semiconductor market as a whole, but of human behaviors that arose in response.Chip shortage will hit hardware buyers for months to years Whether they’re smaller enterprises or big hyperscalers building out capacity, IT decision makers tend to rush into pre-orders whenever headlines about shortages appear, Boujelbene said, and Dell’Oro projects that will true in 2022.To read this article in full, please click here

What is firewall as a service?
So what’s firewall as a service? Firewall as a service, or FWaaS, relies on technology in the cloud. A user or application connects to the FWaaS via the internet, and the service applies domain rules, URL filtering, and other security that physical firewall appliances use. The idea is to replace the multitude of hardware firewalls you’d need to secure all of your business’ traffic from all of its different operational sites with secure internet connections to the service.What’s wrong with firewall appliances? Possibly nothing. Physical firewalls are still quite popular, particularly for businesses without a lot of different locations and without a lot of remote workers. They even have some advantages over FWaaS, like different cost profiles. On-prem firewalls are a capex expenditure up-front but tend to be cheaper over time. They also have lower latency.To read this article in full, please click here

Feds’ demand for software standards could boost enterprise security
Enterprises can look for more transparency from software vendors after the Biden Administration’s recent mandate that software bills of materials be provided by companies attempting to do business with the federal government.Software bills of materials, frequently abbreviated to SBOMs, aren’t a new concept. The idea comes from the manufacturing sector, where it’s often crucial for buyers to fully understand the components and materials that were used to make a particular piece of equipment.The 10 most powerful companies in enterprise networking 2021 For example, a train engine might contain parts that aren’t rated for certain levels of vibration stress, making it unsuitable for use on a particular type of track. The goal of an SBOM is similar, listing all the proprietary, open source, and licensed components being used in a particular piece of software, so that a buyer can review it and check whether any of those components are outdated or insecure.To read this article in full, please click here

Wi-Fi 6E: Don’t let hype push you off your refresh cycle
Despite the inarguable advantages of operating Wi-Fi in the 6GHz frequency range, analysts say that the smart time to buy Wi-Fi 6E is whenever an organization would ordinarily make an upgrade – and not before.Wi-Fi 6E is mostly identical to Wi-Fi 6, but the key difference is the 6E standard’s ability to take advantage of the 6GHz spectrum that was made available for unlicensed use by the U.S. last year. It’s a great deal of new bandwidth, enabling larger channels and consequently higher data rates, as well as being a much less busy area of the spectrum compared to the heavily used 2.4GHz and 5GHz bands.To read this article in full, please click here
