• Building & Scaling LLM Infrastructure

  Understand how large language models are actually trained and served at scale: what the hardware physically constrains, why serving systems are designed the way they are, how to size and cost a deployment from first principles, and where the security boundaries sit. Written for a learner with strong mathematics and general computing ability but no hands-on experience of GPUs, clusters, orchestration or inference servers — so every tool and piece of infrastructure is named and explained before it is used, and every quantitative claim is shown as an explicit calculation with units. Build from the physical machine upward through memory and bandwidth arithmetic, distributed training, inference mechanics, serving at scale, reliability, and security, ending able to size a deployment, read a vendor benchmark critically and diagnose a degraded system.
