FluidCloud calls itself a cloud-cloning platform. In other words, the company can map and copy all the cloud infrastructure settings from one public cloud—including compute, storage, networking, and identity—and port those settings to a different public cloud. On today’s sponsored Day Two DevOps, Ned and Kyler talk with FluidCloud’s co-founders to understand how the platform... Read more »

Kyler Middleton, a software developer in the healthcare sector, builds and supports AI bots and AI agents that are now widely used inside the company where she works. Today on Packet Protector, Kyler stops by to talk about how and why she built these tools, how she (and her organization) address the risks these tools... Read more »

Take a Network Break! Guest commentator Tom Hollingsworth joins Drew for today’s episode. We start with a double Red Alert from Cisco for its Secure FMC software. On the news front, Cato Networks adds adaptive threat prevention to its SASE offering that looks for seemingly innocuous signals that could add up to an attack, Google... Read more »

Software Defined Networking (SDN) is a centralized architecture in which a controller, or a hierarchy of controllers, runs software that computes network-engineered paths and pushes that forwarding scheme into the network. It’s also very complex, which can lead to network failures. What if there was a way to keep the benefits of SDN while also... Read more »

Today’s learning adventure is an overview of multicast. Ethan and Holly have invited a guest to share his multicast expertise: Lenny Giuliano, Sr. Distinguished Systems Engineer at HPE Juniper Networks. Lenny guides them through multicast principles and shares examples of where and how it’s used in live networks. He also explains how the OSPF routing... Read more »

Engineers and developers are using AI like never before, including in production. That has potential consequences, both good and bad, for uptime, operations, security and risk management, and more. Today’s guest, Rich Mogull, guides us through the decision-making process of adding AI to your production lifecycle and possible ramifications. Rich is Chief Analyst at the... Read more »

Today we’re going to learn about the care and feeding of a three-headed dog named Kerberos. Developed at MIT and released in 1989, Kerberos is a free, open source authentication protocol that uses cryptographic keys to protect identity data as it crosses a network. Today, Kerberos is the backbone of Windows authentication. We’ll dive into... Read more »

Take a Network Break! We start with follow-up on the proper pronunciation of the US state of Nevada, and then sound the alarm about new research that gets around WiFi client isolation and could enable man-in-the-middle attacks. On the news front, AMD and Meta strike a massive deal in which AMD will sell its stock... Read more »

With the continued growth of data centers for clouds, neoclouds (especially AI model training), for carriers, and for the enterprise, it’s important to discuss data center network operations and issues. Scott is joined by Dr. Peter Welcher, a consultant, blogger, and Tech Field contributor. Together, they dive into how latency and the rise of AI... Read more »

Our topic today is the designing and building of high-performance networking hardware. If you assume the hardware details don’t matter, you’re missing the intentional engineering required to build truly reliable and quiet infrastructure. In this sponsored episode, we discuss Meter’s hardware philosophy with our guest, Joshua Markell, Head of Hardware at Meter. Joshua walks us... Read more »

Alexis and Kevin sit down with Mike Miller to discuss what brought him from the back of a garbage truck to his current position as a Virtual Chief Information Security Officer (VCISO). He breaks down how a VCISO differs from a CISO, and discusses the two types of clients looking for VCISO services: those looking... Read more »

Eric sits down with David Henderson, Principal Architect for NetDevOps at Presidio, to discuss the practical journey for network engineers transitioning from manual CLI operations to scalable NetDevOps and automation. They discuss how traditional networking knowledge and certifications are foundational, and suggest essential tools and habits for beginning your automation journey. David also shares a...

Traditional routing protocols like OSPF simply choose the “shortest” path. If the shortest path is full of traffic and there are alternate paths carrying nothing, OSPF can’t help you. Path Computation Element (PCE) along with Path Computation Element Protocol (PCEP) is a way to construct forwarding paths through the network based on factors that distributed... Read more »

Today, Ethan and Holly provide an overview of firewalls. While cybersecurity is a separate discipline from network engineering, much of what happens in cybersecurity is interesting at the packet level, so there’s a good deal of overlap. It’s likely that as a network engineer, you’ll be managing, or at least dealing with, firewalls in your... Read more »
