Level 3: Save money on cloud costs
##################################
**Audience:** Users who want to use the AWS cloud efficiently.

**Prereqs:** You must have finished :doc:`level 1 <../basic/build_a_lightning_component>`.

***********************************
Save money with these optimizations
***********************************
A Lightning component gives you fine-grain control over the cloud lifecycle of that component.

Here are a few features that will enable you save a lot on your cloud costs:

Next: Coordinate 2+ components
******************************
Now that you know how to organize arbitrary code inside a Lightning component,
learn to coordinate 2 or more components into workflows which we call Lightning apps.
