The LocalDB instance starts automatically when your application establishes a connection and shuts down when connections close, reducing system footprint and administrative overhead.

Switch to SQLite to eliminate the need for a server engine entirely.

Running from a USB drive will result in low database performance.

If you need to move an entire SQL Server environment between different computers, Docker is the industry standard. By using a Docker container, you bundle the SQL Server engine, its configuration, and the data into a single image. The environment is identical on every machine.
