Kyndryl’s first year yields revenue challenges and a plan to make more

In the year since it spun out of IBM, Kyndryl has made a number of big strides in establishing itself as a core infrastructure service management player, but challenges remain.For example, while it has substantially expanded its partnerships and technology, its financial situation hasn’t shown a similar bump. Just this week the company reported  second quarter revenues of $4.2 billion, a year-over-year drop of 9%. The company has reported similar results in other recent quarters. “Currency and energy-costs impacts are superseding the operational progress we’re making,” Kyndryl CFO David Wyshner told Wall Street analysts during the firm’s 2Q 2023 call this week. “And while the risk of a global recession has clearly increased, we continue to see broadbase demand for digital transformation in infrastructure services.”To read this article in full, please click here

BrandPost: The New Gold Standard: How AIOps Is Transforming Network Capability

You know it better than anyone: the network has become essential infrastructure for any successful enterprise. COVID-19, migration to multicloud, and new application requirements have only amplified pressure on enterprise IT to deliver high-availability, secure network services anywhere, anytime, and on any device.This isn’t a passing fad. Several key trends will drive network growth and complexity for years to come, including: The growing popularity of hybrid and fully remote work models Resource gaps exasperated by the great resignation Dramatic growth in video and cloud meetings An increase in data security regulations To address these challenges and best position themselves for the future, enterprises must implement more intelligence in the network. Modern AIOps uses artificial intelligence and machine learning to assist IT in managing, troubleshooting, and fixing network problems. As a result, AIOps is becoming a key success factor in managing modern enterprise networks.To read this article in full, please click here

AMD posts operating loss, but solid growth for data center, embedded segments

AMD announced third quarter results this week, and while it posted a $64 million loss in terms of overall operating income—mainly due to its acquisition of Xilinx—but large gains in the company’s data center, embedded and gaming segments provided an encouraging note.Total revenue rose by 29% for the third quarter of 2022, to $5.56 billion from $4.31 billion one year ago. Gross profit also rose in year on year terms, from $2.08 billion in last year’s third quarter to $2.35 billion for the past three months. The decline in operating income was caused by much higher operating expenses, which more than doubled in the third quarter, rising from $1.14 billion a year ago to $2.42 billion in the most recent figures.To read this article in full, please click here

Cisco, Red Hat team to streamline hybrid-cloud container management

Cisco and Red Hat have expanded their partnership to include a new combination that lets customers more easily turn-up and manage bare-metal containerized workloads.The companies have integrated Cisco’s cloud-operations management platform, Intersight, and Red Hat OpenShift Assisted Installer, which controls OpenShift clusters, to handle the complex and time-consuming process of networking a containerized environment.Nearly 80% of enterprises have adopted containers in production environments, and containers are especially effective when they are migrated across different hybrid-cloud domains—on-premises data centers, colocation facilities, network edge, and public clouds, wrote Dhritiman “DD” Dasgupta, vice president of  product management for Cisco’s Cloud and Compute team in a blog about the integration. To read this article in full, please click here

NetApp unifies its storage offerings under a new BlueXP roof

NetApp announced Tuesday that its on-premises and cloud storage offerings are now unified under the umbrella of a single platform, called BlueXP, which serves as a control plane for each of its products and simplifies the management of enterprise storage for organizations.BlueXP—which is a free upgrade for its customers—is a reaction to the reality that more and more companies’ storage environments are hybrids these days, combining cloud and on-premises storage, according to NetApp. Businesses of almost any size that have been in operation for more than a decade or so are, more often than not, involved in digital transformation efforts that move at various paces, said company senior vice president and general manager for cloud storage Ronen Schwartz.To read this article in full, please click here

OCP spec for silicon security could help reduce vendor lock-in

A new specification from the Open Compute Project could mean more choices for IT pros when it comes time to replace server cards.The spec defines a block of code that, when used in processors, establishes root of trust (RoT) boot security. Because the spec is open, any chip maker can use it, and it will provide interoperability with chips made by other chip makers that also use it. This can help eliminate being locked into a single vendor because of proprietary RoT code.By standardizing on OCP hardware, for example, it’s possible to replace a bad smartNIC from one vendor with one from another vendor, says Bill Chen, general manager of server product management at Supermicro, an OCP member.To read this article in full, please click here

BrandPost: MSP or DIY: What Is the Best Option for Your SD-WAN Deployment?

The rate of SD-WAN adoption is quickly rising to the point of ubiquity. In an era of distributed environments — including applications, employees, cloud, Edge, and data centers — navigating network complexity has become an increasing common challenge.Recent ESG research found that 54% of survey respondents felt restrained by network complexity in terms of both operational efficiency and user experience. Impacted companies have two solutions for deploying SD-WAN: Do It Yourself (DIY) and or via Managed Service Providers (MSP). It’s up to IT leaders to choose the approach that will most effectively manage their deployments.To read this article in full, please click here

Extreme earnings report: Wireless and cloud gains temper record backlogs

Despite problems getting parts and a gigantic backlog of orders to fill, Extreme Networks landed a record-setting first-quarter FY23 of nearly $300 million, up 11% year-over-year, and 7% quarter-over-quarter.The  backlog CEO Ed Meyercord referred to during the company’s quarterly earnings call this week sits at $555 million, also a record. To put it in perspective, that's nearly three full quarters of product revenue in backlog, mostly due to supply-chain issues. Concerns about the economy are also in the mix, but Meyercord said that when it comes to investing in networks, things look bright.To read this article in full, please click here

Counting individual characters on Linux

Determining how many characters are in a file is easy on the Linux command line: use the ls -l command.On the other hand, if you want to get a count of how many times each character appears in your file, you’re going to need a considerably more complicated command or a script. This post covers several different options.Counting how many times each character appears in a file To count how many of each character are included in a file, you need to string together a series of commands that will consider each character and use a sort command before it counts how many of each character are included.To do that, you can use a command like this one:To read this article in full, please click here

Finding and fixing typos on Linux

If you want to check a text file for typos, Linux can help.It has a couple of tools and a number of commands that can point out the errors including aspell and enchant, and I’ll share a script that I put together recently that looks for typos using the system's words file.Using aspell aspell is very clever tool that will point out typos and make it surprisingly easy to fix them. When used to make changes to a single file, it reverses the text and background colors to highlight misspelled words. You would start it with a command like this:$ aspell check myfile If aspell detects no typos, it simply exits. Otherwise, it will open with a display that contains the file text (or just the top lines depending on the length of the file) followed by a list of suggested replacement words and, below that, a list of the commands that you can run. The first typo (or suspected typo) will be displayed with the text and background colors reversed as shown below.To read this article in full, please click here

IoT security strategy from those who use connected devices

Freeman Health System has around 8,000 connected medical devices in its 30 facilities in Missouri, Oklahoma, and Kansas. Many of these devices have the potential to turn deadly at any moment. "That’s the doomsday scenario that everyone is afraid of," says Skip Rollins, the hospital chain's CIO and CISO.Rollins would love to be able to scan the devices for vulnerabilities and install security software on them to ensure that they aren't being hacked. But he can't."The vendors in this space are very uncooperative," he says. "They all have proprietary operating systems and proprietary tools. We can't scan these devices. We can't put security software on these devices. We can't see anything they're doing. And the vendors intentionally deliver them that way."To read this article in full, please click here
