What does it mean to be irreplaceable on a cloud infrastructure team when AI can write your Terraform, parse your logs, and troubleshoot your architecture — all before your second cup of coffee?
In this episode of The Pluralsight Podcast, Ned Bellavance — infrastructure engineer, Pluralsight author, and host of the Day 2 DevOps podcast — argues that the answer isn't about the tools you know. It's about the judgment, institutional knowledge, and operational experience that no model can replicate. From scripting VMware deployments on a three-person IT team to building reusable Terraform libraries across cloud clients, Ned traces how infrastructure as code evolved and why understanding what's happening underneath the tools has never mattered more.
We dig into where AI genuinely accelerates infrastructure work and where it introduces serious risk — overprivileged credentials, non-deterministic pipelines, and assumptions that only fail once you're in production. We also take a hard look at what leaders are getting wrong right now: cutting junior engineers to offset AI investment costs, undervaluing institutional knowledge that doesn't show up on a balance sheet, and handing AI agents access they were never designed to have responsibly.
Topics covered:
Infrastructure as code fundamentals and why declarative thinking changes everything
How Terraform shifted Ned's approach to infrastructure work
Where AI helps in IaC workflows — and where it creates real risk
Why LLMs should never run your deployment pipeline
The principle of least privilege applied to AI agents
Why institutional knowledge is the hardest thing to replace and the easiest to lose
The junior engineer pipeline problem leaders aren't seeing yet
Skills to prioritize right now: networking, identity, storage, compute, security, and observability
