This week on Pop Goes the Stack, we crack open the next frontier of enterprise infrastructure: DPUs (Data Processing Units). AI factories aren’t just stressing your network—they’re setting it on fire. With east-west traffic exploding and inference storms growing by the day, CPUs and legacy firewalls just can’t keep up. Enter the DPU: purpose-built to offload, secure, and accelerate the chaos. 

We break down:

- Why AI workloads are crushing traditional networking and security architectures 

- How DPUs deliver line-rate telemetry, policy enforcement, and microsegmentation 

- Where companies like NVIDIA (BlueField-3), AMD (Pensando), Intel, Marvell, Fungible, Microsoft (Azure Boost), and Cisco (Hypershield) are racing to redefine infrastructure 

- Why financial institutions, hospitals, and hyperscalers are already deploying DPUs at scale 

- What this means for your observability, east-west controls, and AI agent governance 

The $5.5B DPU market isn’t a footnote—it’s a warning shot. If your stack isn’t built to segment, inspect, and enforce in real-time, it’s not ready for AI. And the next wave of agentic systems isn’t going to wait.
