A Change We Deliberately Kept Manual
A real production change that looked automatable—but wasn’t. This article explains why keeping it manual preserved insight, control, and better future decisions.
-
Blast Radius Is a Design Choice
Blast radius determines how far failures propagate in production systems. This article explains why blast radius is shaped by automation and design decisions, not accidents.
-
How to Validate a Network Design Before Approving It
Most network designs look correct on paper but fail under real conditions. This article explains how experienced engineers validate network designs by examining failure behavior, traffic patterns, dependencies, and operational…
-
Reversibility Is the First Automation Constraint
Reversibility comes before speed in automation decisions. This article explains why the ability to undo outcomes is the first constraint in safe production automation.
-
Why AI-Generated Network Designs Look Convincing (But Often Miss Critical Constraints)
AI-generated network architectures often look correct during early reviews but miss critical operational constraints. This article explains why experienced engineers still rely on human design validation.
-
When Automation Is the Wrong Answer
Automation is a choice, not a default. This article explains when not automating is a deliberate engineering decision to control risk in production systems.
-
7 Hidden Red Flags in Enterprise Network Design Proposals
Enterprise network designs often appear correct during architecture reviews. These seven warning signs help identify proposals that may behave unpredictably in real production environments.
-
What to Automate — and What to Leave Manual (For Now)
Not everything benefits from automation. This article explains how to decide what to automate in production and what to keep manual to control operational risk.
-
Why Network Design Proposals Fail in Production
Enterprise network designs often look correct during review but develop operational issues after deployment. This article explores why otherwise reasonable network proposals struggle in real production environments.
-
Where Automation Actually Works in Production
Automation works best in production when it stays within clear boundaries. This article explores where automation reliably delivers value without increasing operational risk.
