Bootup
Noun · Development
Definitions
The startup phase of a system or application as it initializes state, loads configuration, opens dependencies, and becomes ready to serve work. Bootup behavior matters operationally because slow or fragile startup often causes problems during scaling, failover, and deploys.
In plain English: The process of a system or application starting up.
Example: "The service passed steady-state load tests, but bootup still took ninety seconds because it synchronously rebuilt caches before opening the health endpoint."
