AI for Infrastructure Engineers

Fifth post in the series. In the previous one, we went inside the GPU. This time we automate everything around it. Understanding GPUs is useful. Provisioning them consistently and at scale is where infrastructure engineering actually meets AI. The $4,000 typo I started the week with a win. I manually provisioned a GPU cluster in East US 2 for an ML experiment: AKS with a Standard_NC6s_v3 node pool, accelerated networking, GPU drivers, correct taints. It took most of a day, but it worked. ...

Fourth post in the series. In the previous one, you learned which GPU VMs to provision and how to connect them. This time we look inside the GPU so you can troubleshoot better and talk to the ML team without guessing. The 2 AM ticket Slack fires at 2 AM. The ML team’s training job crashed again. The error is a single line: CUDA out of memory. Tried to allocate 2.00 GiB The data science lead is frustrated: “The model has 7 billion parameters in FP16. That’s only 14 GB. The A100 has 40 GB of memory. There should be 26 GB to spare. What’s going on?” ...

Third post in the series where I translate AI into the language of people who live and breathe infrastructure. In the previous post, we talked about the storage bottleneck nobody notices until it hurts. This one is about compute. Spoiler: it is not enough to buy the most expensive GPU. You need the right GPU, connected the right way. The story you don’t want to live The ML team asks for “a GPU cluster for training.” You do what any infra engineer would do under time pressure: provision eight Standard_D64s_v5 VMs. Sixty-four vCPUs each, 256 GiB of RAM, Premium SSD. On paper, it looks respectable. ...

This is the second post in the series where I translate AI into the language of infrastructure engineers. In the first post, I showed that AI is just another workload and that your infra skills already prepare you more than you think. Now for the bottleneck everyone ignores: storage. It is the hidden villain behind performance problems in almost every AI project I’ve seen. The midnight call You did everything right. The ML team asked for a GPU cluster and you delivered: eight NVIDIA A100s across two nodes, high-bandwidth networking, CUDA drivers up to date. Clean deployment. The team kicked off their first training job Friday at 6 PM and you went home feeling good. ...

This is the first post in a series where I’ll translate the world of AI into the language that infrastructure engineers already speak. If you’re the kind of professional who configures VMs, builds CI/CD pipelines, and gets woken up at 2 AM when Nagios fires, this content is for you. The series is based on my open-source book AI for Infrastructure Professionals, adapted and expanded here on the blog. The Monday morning message It’s 8:47 AM on a Monday. You’re halfway through your coffee, reviewing a Terraform plan for a network redesign, when a Slack message lights up your screen. It’s from the data science team lead: ...
