Docker and the Three Ways

The First Way: Systems Thinking

Left to Right Flow• Variety!

• Determine your variety of offerings based on operational efficiency and market demand!

• Velocity!• Maintain a steady flow through all

processes of the supply chain!• Variability!

• Manage inconsistencies carefully to reduce cost and improve quality!

• Visibility!• Ensure the transparency of all

processes to enable continuous learning and improvement

Left to Right Flow•Variety

• Lean Startup

• Minimal Viable Product

• Build Measure Learn

• Customer Development Methodology

Left to Right Flow

• Velocity!

• Developer Flow

• Integration Flow

• Deployment Flow

Left to Right Flow

• Variation

• Converged Isolation

• Immutable Infrastructure

• Immutable Delivery https://en.wikipedia.org/wiki/Standard_deviation

@bglpe

“The least-cost way to ensure that the behavior of any two hosts will remain completely identical is always to

implement the same changes in the same order on both hosts.”

Order Matters

Management Methods

• Divergence

• Convergence

• Congruence

Left to Right Flow

• Visibility!

• Containerization

• Microservices

• Data Gravity

Case Studies

The Second Way: Amplify Feedback Loops

Right to Left Flow

• Variety

• Velocity

• Variation

• Visualization

The Third Way: Culture of Continuous Experimentation and Learning

( Invisible )

I have no idea how to answer

that question. It would literally

never occur to me not to do it!

We are what we repeatedly do. Excellence, then, is not an

act, but a habit. !

Data Science

• Capital One

• Analytics and Sports

• Containers as a Service

Faster, Cheaper Safer• Agile, Lean and Rugged

• You Build it you Run it

• Change One Thing at a Time

• Fail Early Fail Often

• Developer Defined Infrastructure
