What is the difference between scaling and performance optimization?

Scaling refers to the ability of a system to handle increased load by adding resources, while performance optimization focuses on improving the efficiency of existing resources.

Can you give me an example of scaling?

Sure! An example of scaling is adding more servers to a web application to handle more users during peak traffic.

And what about performance optimization?

Performance optimization might involve refining code, optimizing database queries, or using caching to make the application run faster without adding more resources.

Which one should I focus on first?

It depends on your current situation. If your system is struggling to handle load, scaling might be necessary first. If it's running slowly, then performance optimization should be prioritized.
