What is Laravel zero-downtime deployment strategy?

Zero-downtime deployment ensures users experience no service interruption during releases.

Laravel zero-downtime deployment is achieved using strategies like atomic deployments, shared storage, symlink switching, and tools like Envoyer or Deployer. A new release is prepared in a separate directory, dependencies are installed, migrations are run carefully, and then a symlink is switched to point to the new release. This ensures uninterrupted traffic flow. Proper handling of caches, queues, and database migrations is critical.
