IT'S NOT MICROSERVICE OR MONOLITH; IT'S COGNITIVE LOAD YOU NEED TO UNDERSTAND FIRST

Summary from the TLDR Web Dev newsletter

A monolithic architecture with a focus on cohesive and modular designs to match the team's cognitive load may be favorable for single teams. Conversely, for multiple teams, microservices or similar architectures allow for independent work but require well-designed APIs to mitigate extraneous cognitive load. Software architecture is ideally designed to fit the maximum team cognitive load to avoid overstretching teams and ensure alignment between organizational capacity and architectural decisions.
