The realm of network observability is changing quickly in the modern generative AI era as vendors embrace and integrate increasingly sophisticated intelligence. Network observability provider Kentik, which got its start back in 2014 as CloudHelix before being rebranded in 2015, has always been focused on helping networking professionals do their jobs, which can often include lots of repetitive ta…

Many companies — including IBM itself — demonstrated uses of quantum computers that went beyond what was possible with purely classical approaches this year. But none of these were clear, undisputable demonstrations of quantum superiority, reproducible, and applicable to more than just one cherry-picked use case. “The problem is that there aren’t standardized benchmarks for quantum computing yet,…

Microsoft is betting big on agentic AI to simplify and automate cloud operations by introducing an agentic mode to Azure Copilot that could surface insights and provide recommendations, but not take any actions. While the hyperscaler is pitching the upgraded Copilot as a tool that simplifies cloud operations at scale by taking actions on its own, as opposed to traditional management tools that wo…

The reliability of services delivered by ISPs, cloud providers and conferencing services is critical for enterprise organizations.

Enterprises running VMware’s vSAN storage platform may have spent significantly more on hardware than necessary. The company has acknowledged that its long-standing sizing recommendations were based on synthetic testing that did not reflect real-world conditions. VMware revealed that analysis of telemetry data from thousands of production vSAN clusters showed that “vSAN clusters use much less RAM…

Azure has blocked its largest DDoS attack to date, a 15.72 Tbps strike linked to the Aisuru IoT botnet that also surged to nearly 3.64 billion packets per second and targeted a single cloud endpoint in Australia, Microsoft said. “The attack involved extremely high-rate UDP floods targeting a specific public IP address, launched from over 500,000 source IPs across various regions,” the company wro…

Bragging rights are a staple in the Silicon Valley, and perhaps no one does it better than Nvidia. But its latest claim to fame is impressive . At this week’s Supercomputing 25 conference in St. Louis, Nvidia announced that more than 80 new science-oriented systems powered by its platform have been deployed around the globe in the last year, at a combined total of 4,500 exaFLOPs of AI performance…

At this week’s Supercomputing Conference, SC25 conference in St. Louis, Missouri Nvidia highlighted how it expects to accelerate computing to quantum processors in the future. Nvidia only in October introduced NVQLink interconnect to let lets GPUs and quantum chips to each other. The package is built on the NVLink interconnect for direct CPU-to-GPU communications. Nvidia might be getting ahead of…

Arm is hedging its AI networking bets, joining Nvidia’s NVLink Fusion ecosystem in addition to the rival UALink consortium that it joined last year.
