Scalability is a measure that shows the ability of a system to expand its capabilities to handle an additional load. One of the strongest sides of Jenkins is that it has a scaling feature almost out-of-the-box. Jenkins scaling is based on the master/slaves model, where you have a number of agent instances (called slaves) and one main Jenkins instance (called master), which is responsible mainly for distributing jobs across slaves. Sounds simple right? 

Well, even if the scalability feature is available in Jenkins out-of-the-box, this doesn’t mean that the process of making Jenkins scalable will be fun and easy.

In this course i want to learn you how you can easily dynamical scale Jenkins slaves and save resources while Jenkins is idling.
