Graceful Shutdowns:
A graceful shutdown is the process of shutting down a service or application in an orderly and controlled manner, ensuring that any in-progress operations or tasks are completed before the service terminates. This approach aims to prevent data loss and corruption, improve the user experience, and prevent unexpected application states. This process is flexible and tailored to fit the specific needs of an application.

How it typically works:
1. The service receives a signal indicating it should shut down (e.g., a SIGTERM signal on Unix systems).
2. The application stops accepting new requests or tasks.
3. The application waits for ongoing tasks or operations to be completed.
4. Resources like connections are released from memory.
5. The application terminates.
