Design Principles for Cost Optimization
In this section, we explore the balance between performance and cost—crucial for delivering optimal value. Here, value is defined as achieving high performance without overspending. The key design principles include:- Measuring overall efficiency.
- Avoiding excessive spending on non-differentiators.
- Embracing a model of variable consumption.

Always monitor your performance metrics to ensure that cost-cutting does not impact application performance negatively.
