Long lived Development is iterative and constant
Monolithic and built on a single stack Built from loosely coupled components
Deployed to a single server Deployed to a multitude of servers
Apps Have Fundamentally Changed

…in between, can be loaded and
unloaded, stacked, transported
efficiently over long distances, and
transferred from one mode of
transport to another
A standard container that is
loaded with virtually any
goods, and stays sealed until it
reaches final delivery.

19. This eliminated the NxN problem

20. The Right Approach to Containers Matters
• Separation of concerns
• Automation
• Efficiency
• Broad ecosystem

23. An Open Platform to Build, Ship, and Run Distributed Applications

24. Containers vs. VMs

25. Why are Docker containers lightweight?

26. What are the basics of the Docker system?

• Deploying and scaling more easily
• Achieving higher density and running more
workloads
