Congratulations! We've reached the end of the course! It's been a long journey, but since we've started, you've learned so much. From that first Salt install to our orchestration state that provisions a full LAMP stack, we've written formulas, run execution modules, learned how to use the event system for self-healing, responsive infrastructure, and got deep into just how Salt does the things it does. You have the skills to pass the SSCE and to manage Salt in the real world.
If you're interested in further expanding your Salt skills, I suggest taking a look at our Python 3 course, Python 3 For System Administrators. Salt, as we know, is written in Python, and if you want to venture into writing custom execution modules other features, learning Python is the right place to start.
