DPUs and SmartNICs are the hidden third processor in every major cloud server. Here is how AWS Nitro, Azure Boost, NVIDIA BlueField, and Google Titanium work, what they offload, and why it changes how you think about cloud performance guarantees.
A deep dive into Envoy's xDS APIs, filter chain model, threading architecture, and why it became the universal data plane powering Istio, AWS App Mesh, and Kubernetes Gateway API.
BGP was designed for trust, not security. Twenty years into my career, I've watched route hijacking incidents take down services that no application-layer defense could stop. Here's how RPKI changes that.
Learn how BGP anycast routing lets a single IP address be served from hundreds of global locations at once, powering CDNs, DNS infrastructure, and DDoS mitigation at scale.
Cloud egress fees silently drain budgets because most engineers model compute and storage costs but ignore data movement. Here is how the pricing actually works, which architectural patterns create the worst bills, and how to engineer your way to a dramatically lower number.
How AWS Direct Connect, Azure ExpressRoute, and Google Cloud Interconnect work, when to use each, and how to design hybrid cloud connectivity that actually holds up in production.
VPC Peering, Transit Gateway, PrivateLink, and VPC Lattice solve different connectivity problems. Here is how each one works, when to use it, and the decision framework I use with every client who has more than a handful of VPCs.
WireGuard's simple cryptographic model, blazing performance, and native Kubernetes integration make it the VPN protocol cloud infrastructure teams should be running. Here's how it actually works and how to deploy it.
SD-WAN and SASE are reshaping how enterprises connect offices, clouds, and remote workers. Here's what they actually are, how they differ, and when each makes sense.
A practical guide to eBPF: how it works at the kernel level, why Cilium replaced iptables for Kubernetes networking, and how eBPF powers next-generation observability without sidecars.
Learn CIDR notation, subnet masks, and how classless addressing replaced the old Class A/B/C system. Practical examples for cloud VPC design and network planning.
Practical deep dives on infrastructure, security, and scaling. No spam, no fluff.
