The Twelve-Factor App methodology is a set of 12 best practices for building modern SaaS applications — created by Heroku engineers from patterns across thousands of production apps. This guide explains each factor (codebase, dependencies, config, backing services, build/release/run, processes, port binding, concurrency, disposability, dev/prod parity, logs, admin processes) with examples.

A deployment script (typically deploy.sh) automates the steps from a built artifact to a running production service — with rollback and health checks.

GitOps uses Git as the single source of truth for infrastructure and deployments. Learn the principles, see how push-based and pull-based models differ, and why you don't need Kubernetes to start.

Most deploys should be incremental — but sometimes you need to send everything. Here is when a full deployment is the right call, what it costs in time and bandwidth, and how to run one safely in DeployHQ.

Incremental deployments upload only the files that changed — turning a 4-minute full deploy into a 10-second push. See real benchmarks, learn how they differ from incremental rollouts, and get tips to make them even faster.
