Foundations

DevOps
A culture and set of practices uniting development and operations to deliver value continuously, improving flow from idea to production.
Why DevOps
It accelerates time-to-market, improves quality and stability, and enables faster feedback, supporting agility at scale.
Culture of Shared Responsibility
Development, operations, security, and business share responsibility for delivering and operating solutions.
Three Ways of DevOps
Flow (fast left-to-right delivery), Feedback (fast right-to-left learning), and continual experimentation and learning.

Pipeline

Continuous Delivery Pipeline
The workflow and automation delivering new functionality: continuous exploration, integration, deployment, and release on demand.
Continuous Integration (CI)
Frequently integrating, building, and testing changes so defects surface early and the system stays working.
Continuous Deployment (CD)
Automatically moving validated changes toward production, reducing time-to-market and deployment risk.
Release on Demand
Releasing value to users when the business needs it, decoupled from the development cadence.
Deployment vs. Release
Deployment moves code to production; release exposes features to users. Separating them enables safe, on-demand release.

Automation

Automation
Automating build, test, deployment, and monitoring to increase speed, repeatability, and quality.
Infrastructure as Code
Managing infrastructure through versioned code so environments are consistent and reproducible.
Test Automation
Automating tests so they run frequently, giving fast feedback and enabling continuous integration.
Continuous Testing
Building testing into every stage of the pipeline so quality is verified continuously.

Quality & Security

DevSecOps
Integrating security throughout the pipeline so it is built in continuously rather than added late.
Built-In Quality
Practices that keep quality high throughout development, reducing rework and enabling frequent releases.
Shift Left
Moving testing and security earlier so issues are found and fixed when cheap.

Flow & Measurement

Value Stream Mapping
Mapping the delivery pipeline to find delays, handoffs, and waste to remove.
Lead Time and Cycle Time
Measures of how long work takes to flow through the pipeline, used to target improvement.
DORA Metrics
Deployment frequency, lead time for changes, change failure rate, and time to restore — key measures of DevOps performance.
Feedback Loops
Fast feedback from monitoring and testing that lets teams detect and fix problems quickly.

Culture & Scale

Recovery and Resilience
Designing for low-risk releases and fast recovery so teams deploy frequently with confidence.
Breaking Down Silos
Aligning dev, ops, security, and business into shared goals and workflows.
Scaling DevOps
Extending DevOps practices across teams and value streams to accelerate the whole enterprise.
Continuous Improvement
Relentlessly measuring and improving the pipeline so flow, quality, and speed keep getting better.
