Startup Alkira has built a Network as a Service (NaaS) offering that extends from on prem to public cloud and multi-cloud. Today's sponsored episode of Heavy Strategy digs in to Alkira's capabilities in multi-cloud networking, security, automation, and cost transparency. Guest Manan Shah, SVP of Product at Alkira, explains how Alkira simplifies network management, enhances security, and provides flexibility for customers. We also discuss use cases, a new ZTNA capability, and security feature integrations. Listen here or wherever you get your podcasts - https://lnkd.in/gsr22hQg

This episode was recorded live at Security Field Day (XFD) 12 in October, 2024. As delegates at the event, Jennifer Minella and Andrew Conry-Murray heard presentations from DigiCert, Dell Technologies, SonicWall, and Citrix. These presentations covered topics including digital certificate management, post-quantum cryptography, supply chain security, recovering from ransomware, Zero Trust Network Access (ZTNA), and Secure Service Edge (SSE). We discuss the highlights of each presentation and our takeaways. Listen here or wherever you get your podcasts - https://lnkd.in/gVUZeFka

Take a Network Break! This week we discuss a new ZTNA offering from NaaS startup Alkira, a serious vulnerability in Fortinet's management software under active exploit, and a less-serious vulnerability in Cisco security software that's also being exploited. Gluware adds new AI copilots to its network automation software, a judge orders Broadcom to continue to support a VMware contract for AT&T as a lawsuit grinds through the legal process, and the FCC mulls a ban on ISP data caps. IBM sees revenues rise but misses Wall Street expectations, and BT experiments with a solar- and wind-powered mobile site. Listen here or wherever you get your podcasts - https://lnkd.in/grzeFm8a

Ethernet competes with InfiniBand as a network fabric for AI workloads such as model training. One issue is that AI jobs don’t tolerate latency, drops, and retransmits. In other words, AI workloads do best with a lossless network. And while Ethernet has kept up with increasing demands to support greater bandwidth and throughput, it was never designed to be lossless. ASIC makers, switch vendors, and industry groups aim to optimize Ethernet to make it a suitable network fabric for AI jobs. On today’s Heavy Networking we talk about those efforts, explore different optimization techniques, compare Ethernet and InfiniBand, and discuss general design considerations to be aware of if your organization decides to go down the Ethernet path for AI. Our guests are Chris Kane, Sr. Manager Systems Engineering at Arista Networks, and Pete Lumbis, Principal Engineer at Nvidia. Listen here or wherever you get your podcasts - https://lnkd.in/g8Eqf6Sf

Leadership has a huge impact on an organization's culture, including tech teams. On the positive side, leaders can foster healthy, productive environments. On the negative side, they can build hostile, blame-centric viper pits. Today's episode of Technically Leadership examines how to strive for the positive by shielding teams from internal politics, developing empathetic leadership, distinguishing between blame and accountability, and addressing toxicity. Host Laura Santamaria and guest Boyd Hemphill, CTO of VICTORY CTO, discuss the importance of empathy, transparency, and supportive team culture as the path to effective technical leadership.

Network optimization starts with observing, but how are networks observed and what tools are used? Joining the podcast today are the authors behind the book "Modern Network Observability." Eric Chou welcomes David Flores , Christian Adell, and Josh VanDeraa to help uncover practical strategies and real-world case studies for network observability.

Enterprise data is everywhere: on prem, at the edge, and across the public cloud. Storing and managing that data involves more than just SSDs and spinning disks; it's about building and operating a data infrastructure. On today's Day Two DevOps podcast, host Ned Bellavance explores the idea of data infrastructure with Jeff Baxter, VP of Product Marketing at NetApp. Jeff and Ned talk about the challenges of managing storage in the modern era of cloud and AI. They also discuss how cybersecurity and storage intersect, data gravity, and unified monitoring. NetApp is the sponsor of today's episode.
