This lesson is planned. The outline below lists the topics it will cover. The full lesson has not been published yet.
In this lesson
treat cost as a design quality next to reliability and performance.
Planned topics
- Cost is shaped by architecture decisions: data movement, redundancy, always-on versus on-demand.
- Cost, reliability, and speed trade against each other; make the trade explicit.
- A merged platform (Shop plus FulfillCo) often duplicates services; duplication is a cost lever.
- Cost needs an owner and a regular review, like any other quality.
