Most companies treat deployment as an event. Something you plan, schedule people for, and hope goes well. Here it's a background process that happens every ten minutes, around the clock.
The agent detects a new commit, builds the backend and frontend, runs all 3,243 tests and deploys every component. Files are staged first and swapped into place atomically, so the live site never exists in a half-updated state. If any component fails, the pipeline retries next cycle; nothing is marked done that isn't actually done.
The result is a system where shipping is boring. Code that's merged is code that's live ten minutes later, verified by the same gates every single time. No deploy windows, no release managers, no Friday freezes.
