Phase 4 - Deliver on Demand | Scope: Org | Original content

Deploy on demand means that any change which passes the full automated pipeline can reach production without waiting for a human to press a button, open a ticket, or schedule a window. This page covers the prerequisites, the transition from continuous delivery to continuous deployment, and how to address the organizational concerns that are the real barriers.

Continuous Delivery vs. Continuous Deployment

These two terms are often confused. The distinction matters:

Progressive Rollout

Phase 4 - Deliver on Demand | Scope: Team | Original content

Progressive rollout strategies let you deploy to production without deploying to all users simultaneously. By exposing changes to a small group first and expanding gradually, you catch problems before they affect your entire user base. This page covers the three major strategies, when to use each, and how to implement automated rollback.

Why Progressive Rollout?

Even with comprehensive tests, production-like environments, and small batch sizes, some issues only surface under real production traffic. Progressive rollout is the final safety layer: it limits the blast radius of any deployment by exposing the change to a small audience first.

Experience Reports

Theory is necessary but insufficient. This page collects experience reports from organizations that have adopted continuous deployment at scale, including the challenges they faced, the approaches they took, and the results they achieved. These reports demonstrate that CD is not limited to startups or greenfield projects - it works in large, complex, regulated environments.

Why Experience Reports Matter

Every team considering continuous deployment faces the same objection: “That works for [Google / Netflix / small startups], but our situation is different.” Experience reports counter this objection with evidence. They show that organizations of every size, in every industry, with every kind of legacy system, have found a path to continuous deployment.
