Monolithic and built on a single stack Built from loosely coupled components

Deployed to a single server Deployed to a multitude of servers

…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

a lightweight, portable, self-
