Make a workload elastic: no local state, scalable by adding instances, tolerant to losing one
Make a workload elastic: move state out of the instances, loose coupling between components, adding an instance behind the load balancer without changing the code, losing an instance with no client-side error, while telling elasticity and scalability apart.

Beyond the lessons
Assess, practise, pass the proof
Reading a lesson confirms nothing. A skill is confirmed by a passed quiz, practised in a guided lab, and put to the test by a challenge or a mission; an imported lab result is not verified by the site.
