    The perimeter has shifted

    The perimeter isn’t where you left it. Agents are on the move, APIs are on fire, and your infrastructure is about as ready for this as a fax machine is for a DDoS. In this week's episode, Lori, Joel and F5 Field CISO, Chuck Herrin, are talking guardrails—real ones—for the age of agentic AI.   Because while your dashboards were busy sipping metrics, the vendors got serious. Recent product launches show a clear pivot toward AI-specific defenses and infrastructure support like: an AI firewall, AI runtime protection, semantic observability, and AI policy and rule generation.    Turns out, stateless APIs weren’t built for recursive agents with infinite retries and zero chill. If your architecture still thinks AI means ‘autocomplete,’ you’re going to want to tune in for actionable steps to stay ahead in an AI-dominated future. It’s not just about security. It’s survival. Let’s go.

    Old is New Again: Bandwidth will be the AI bottleneck

    AI doesn't just chew up compute—it eats your network for breakfast. In this episode of Pop Goes the Stack, F5's Lori MacVittie, Joel Moses, and Ken Arora dig into the pressing issues surrounding AI workloads and networking. Everyone's worried about GPUs and cooling, but nobody’s talking about the lateral east-west traffic explosion, the rise of inter-agent comms, or the operational strain on DCN fabric and interconnects. Our experts discuss the importance of upgrading data center networks to accommodate AI demands, examining the differences between training and inferencing workloads. The conversation also covers the necessity of high-performance networking, the relevance of latency, data gravity, and the potential expansion of data centers. Tune in to get valuable insights into the challenges and solutions shaping the future of AI-driven applications.

    Fine-tuning on a Budget

    Big models, tight budgets? No problem. In this episode of Pop Goes the stack, hosts Lori MacVittie and Joel Moses talk with Dmitry Kit from F5's AI Center of Excellence about LoRA (Low-Rank Adaptation), the not-so-secret weapon for customizing LLMs without melting your GPU or your wallet. From role-specific agents to domain-aware behavior, we break down how LoRA lets you inject intelligence without retraining the entire brain. Whether you're building AI for IT ops, customer support, or anything in between, this is fine-tuning that actually scales. Learn about the benefits, risks, and practical applications of using LoRA to target specific model behavior, reduce latency, and optimize performance, all for under $1,000. Tune in to understand how LoRA can revolutionize your approach to AI and machine learning.
