~2000 2014Long 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

o I worry about how

goods interact (e.g. coffee beans next to

spices)

Can I transport quickly

and smoothly

(e.g. from boat to train

to truck)

…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.

This eliminated the NxN problem

The Right Approach to Containers Matters

• Separation of concerns• Automation• Efficiency• Broad ecosystem
