It would be useful to have a set of architecture principles and requirements to guide all Wikimedia engineering endeavors. Such principles and requirements should be derived from the Wikimedia movement's strategic direction and the Wikimedia Foundation's product strategy as well as established best practices of the software industry. They should be informed by past experience as well as present needs and constraints, and are expected to evolve when these needs and constraints change.
TechCom has been working on a draft of such principles since April 2018. This RFC proposes to adopt the Architecture Principles draft as official policy.
