Trocar de provedor sem dor de cabeça: a importância de um domínio agnóstico

The article is a Portuguese-language developer piece on the challenge of switching service providers in fast-moving products. It notes that products often change due to new investors, customers, or stakeholder decisions. The author uses payment providers as an example, where a system built around one provider becomes tightly coupled to its vocabulary and code. Such coupling makes a later switch costly, with duplicated logic and repeated checks across the codebase. The author recommends designing a provider-agnostic model and code, illustrated by a translator per provider layer.
