Aruba chief: Enterprises must adjust to new normal of remote working

When HPE bought Aruba in 2015, Aruba’s then-president and CEO Dominic Orr said that his company had effectively acquired HP Networking. Aruba’s performance since then has largely borne out Orr’s bullish prediction, as the company has become the driving force behind HPE’s enterprise networking efforts and dramatically grown its market share, expanding beyond its roots as a primarily mid-sized campus networking provider to become a leading competitor to the market’s 800-pound gorilla, Cisco.With HPE’s most recent earnings reports showing the Aruba division having posted $806 million in revenues for the first fiscal quarter of 2021, up 12% year-over-year, Keerti Melkote, president and founder of Aruba, sat down with Network World to talk about network architecture, competing technologies and more.To read this article in full, please click here

Comcast: Internet usage spiked in 2020 as working from home doubled

Overall Internet traffic on Comcast’s network spiked substantially at the beginning of the pandemic in the U.S. in March 2020, but normalized over the subsequent months, according to a report released today by the internet service provider.As the largest individual home ISP in the U.S., Comcast’s data on Internet usage represents a useful snapshot into overall home connectivity during the pandemic.[Get regularly scheduled insights by signing up for Network World newsletters.] Nearly two-thirds of Americans--62%--reported working from home at some point during the current crisis, double the figures for the previous March, the report found. And 93% of households with school-age children reported that those children engaged in distance learning.To read this article in full, please click here

Linux server certifications becoming a must-have for IT pros

Linux certification is increasingly significant for tech workers as the public cloud and software-defined networking become ever more important. A Linux cert can set IT professionals apart from the herd and potentially put a lot more money in their bank accounts.Once these certifications were a gauge of reliability, according to CompTIA chief tech evangelist James Stanger. “Twenty years ago, Linux tended to attract people who were a little edgier,” he said. “So certification was traditionally used in the Linux side just to find people you can work with—will they show up on time?”Now, these certifications are a demonstration not only of proficiency but also dedication to self-improvement. “You can’t go wrong with a certification,” said Joe Faletra, director of infrastructure services at Modis, a technology staffing and consulting firm. “I’ll lean towards certs over experience [in hiring], because this person has put the effort into learning and passing the exam.”To read this article in full, please click here

Report: IT employment improves in January

More than 18,000 new IT jobs sprang up in January as the overall outlook for tech hiring substantially improved over the past several months, according to figures from the Bureau of Labor Statistics and research firm Janco Associates.Between that new hiring and adjustments made to the job market totals in the latest BLS numbers, the IT sector has now recouped 53,600 of the roughly 100,000 jobs it lost due to the COVID-19 crisis, according to Janco principal M. Victor Janulaitis.[Get regularly scheduled insights by signing up for Network World newsletters.] What’s more, the upward trajectory seems likely to continue, as the changing IT jobs market grows and changes, according to his projections. “IT job-market growth will expand by almost 11% in the post-COVID era,” he said. “Most of the growth in the IT job market will be with software developers, quality assurance, and testers. This will be driven by [work from home] as it is embraced by more enterprises in normal operations and internet-centric applications are developed and deployed.”To read this article in full, please click here

Network slicing: Wireless virtualization to build 5G services and conserve spectrum

Network slicing technology has large parts of the wireless networking community excited, and it’s easy to understand why: It can deliver multiple logical networks over a single physical infrastructure and give each network the unique set of characteristics required to meet specific user needs.The idea of re-using scarce radio-frequency spectrum to create more value for providers that own the infrastructure, in addition to the ability to offer over-the-top services beyond mere connectivity, has the telecom giants interested, particularly those deploying 5G cellular services.To read this article in full, please click here

Will carriers use 5G to provide edge services?

US mobile carriers see an opportunity to broaden their role in the enterprise marketplace as the rush to deploy 5G continues, but it’s unclear whether their strategy will be sufficient to achieve that goal, according to industry analysts. 5G resources What is 5G?

IT workforce suffering under COVID-19, waiting on herd immunity for rebound

For the first year since the dot-com bubble popped, IT salaries were largely flat in 2020, and tens of thousands of jobs were lost in 2020, according to a report from independent management consultants Janco Associates.Hardest-hit were middle management jobs at both large enterprises and smaller companies, where salaries actually dropped by about 0.08%, while executive and staff-level jobs remained steady or grew by a similarly small amount.“What’s been hard hit, mostly, are IT organizations and SMBs,” said Victor Janulaitis, the CEO of Janco, which published the report. “That’s where the majority of the IT jobs are in the marketplace today.”To read this article in full, please click here

Deloitte: 5G to drive edge, open RAN to the forefront in 2021

Edge computing is flagged as a key networking technology for 2021 as well as open radio-access framework, both of which are fundamentally driven forward by mobile data carriers and their rush to deploy 5G, according to Deloitte.The EdgeEdge computing, including compute workloads being handled on or close to endpoints deployed outside the data center, will be among the biggest technological growth areas in 2021. Deloitte predicts that the global market for edge products will rise to $12 billion in 2021, and will continue to grow at a rate of 35% per year thereafter. Close to three-quarters of all businesses, by 2023, will deploy some form of edge computing, the researchers said.To read this article in full, please click here

Wide-open spaces: Big spectrum gains to boost Wi-Fi capability in 2021

Two recent FCC decisions will dramatically increase the capabilities of new Wi-Fi systems in the coming year, providing badly needed breathing room to the unlicensed wireless world.The first allocation, announced in April, will throw open the entirety of the 6GHz spectrum range for unlicensed use, and the second, rolled out late last month, adds a small but critical amount of spectrum to the 5GHz band.Both of these decisions are important to future Wi-Fi deployments because they directly affect the amount of spectrum available for Wi-Fi to operate in. More bandwidth means larger channels, which translates directly into improved throughput for users.To read this article in full, please click here
