#70 - Continuous Architecture (Part 2) - Principles, Scalability, and Performance - Pierre Pureur

“Delay design decisions until it’s necessary. Architecture is an art, not a science. Don’t architect for things you don’t know. Your design decisions should always be built on facts, not guesses."

Pierre Pureur is the co-author of “Continuous Architecture in Practice” and an acclaimed software architect. In this second of a three-part series of “Continuous Architecture” episodes, Pierre shared his own perspectives on the 6 key principles of continuous architecture. We then discussed in-depth the two important quality attributes, which are the scalability and performance. For each quality attribute, Pierre described the attribute definition, why it is an important architectural concern, and some of the common tactics used to improve the attribute in the modern system architecture.
