Capacity at product-area scale
On This Lesson 4 topics
This lesson is planned. The outline below lists the topics it will cover. The full lesson has not been published yet.
In this lesson
extend capacity planning from one service to a product area with many dependent services.
Planned topics
- One business event (an order) fans out into calls across many services; capacity is a chain.
- The bottleneck moves as load grows; plan the whole path, not each service alone.
- Capacity planning links business drivers, technical load, and spend on a calendar.
- Keep headroom for peaks and failure of a zone, not only average load.
