What does "rollout" mean in programming?
rollout is one of the most common terms in software development. This guide explains what it means, how it is used in practice, and why it matters, with real examples from the developer world.
Definition
The process of gradually releasing a feature or change to users, often in stages (1%, 10%, 100%). A phased rollout allows monitoring for errors before full release and minimizes the blast radius of any problems.
Example
"We did a phased rollout — 1% of traffic first, then 10%, then full rollout after 24 hours with no errors."
