Cost-performance optimization
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
optimize cost and latency together, not separately.
Planned topics
- Use cost per transaction at a target latency as the common measure.
- Options: caching, right-sizing, batching, async processing, different storage tiers, reserved capacity.
- Every latency target has a price; ask the business what it is worth.
- Measure after a change; optimizations that save little at high complexity are not worth it.
Draft outline details
Demonstration
a curve sketch: cost per order against p99 latency, with the knee where extra speed becomes expensive, and a marked target.
