Finding Your Abstraction Sweet Spot
summary
Argues that abstractions are the third hard problem in software and defines abstraction as encapsulated complexity, contrasting strong vs weak abstractions with concrete infra milestones: physical servers → VMs → containers → PaaS → serverless. Says the right level is a tradeoff of flexibility vs ease-of-use, warns of measurable harms (frequent breaking changes, long-lived tech debt, user confusion), and prescribes practical choices: pick audience and platform, state lifespan or beta, start at one end and iterate while planning how to pay down debt.
