Essays

Canonical arguments and analysis on decision quality under uncertainty. Each essay examines a specific question through explicit reasoning and structured evaluation.

Cross-Account AWS Costs Nobody Tracks

What categories of AWS costs emerge specifically from multi-account organizational structures - cross-account data transfer, shared service replication, organizational boundary overhead - that standard cost monitoring fails to capture, and why do these costs often represent 15-30% of total infrastructure spending?

How multi-account AWS structures create hidden cost leakage through cross-account data transfer that billing systems fail to capture (15-30% of spend).

Why Database Read Replicas Doubled Our Costs

Under what conditions do database read replicas - RDS read replicas, PostgreSQL replicas, MySQL replicas - deployed to distribute read load and improve performance create cost structures where replication overhead, connection management, and query routing complexity exceed the performance and cost benefits replicas provide?

How read replicas create cost structures where replication lag and routing complexity eliminate performance benefits while doubling infrastructure costs.

The $50,000 Logging Bill: Observability Cost Explosion

Why do observability systems - specifically logging, metrics collection, and distributed tracing - create cost structures that often exceed the infrastructure costs of the applications they monitor, and under what conditions does adding observability reduce overall system reliability?

How observability systems create cost structures where logging and monitoring overhead exceeds application infrastructure costs by 2-4x.
