    • Set of commands describing how to run your app
    
    
    • Write once, run anywhere
    
    
    • The "ABCs" of your Cloud journey

13. Docker – The Why
    • Imagine buying a new computer
    
    
    • You set it up and install apps
    
    
    • Run system updates, etc.
    
    
    • Software:
