Big Bang Deployment
Big Bang Deployment is a software release strategy where a new version of an application or system is deployed all at once, replacing the previous version entirely in a single, high-impact event. This approach involves shutting down the old system, deploying the new one, and then restarting operations, often resulting in significant downtime and risk. It contrasts with incremental deployment methods like canary releases or blue-green deployments, which aim to minimize disruption.
Developers should consider Big Bang Deployment when dealing with legacy systems that lack modular architecture, making incremental updates impractical, or for small-scale applications where downtime is acceptable and the simplicity of a one-time switch outweighs the risks. It is also used in scenarios with tight coupling between components, such as monolithic applications, where partial deployments could cause inconsistencies, but it is generally discouraged for critical production systems due to its high failure potential and user impact.
