What are the differences between 'mongodb://' and 'mongodb+srv://' URI schemes?

The 'mongodb://' scheme requires you to provide username, password, and the database name directly in the URI. The 'mongodb+srv://' scheme uses a connection string that includes the cluster hostname, database name, and authentication details. 'mongodb+srv://' is often preferred for cloud deployments as it abstracts away the underlying infrastructure and provides a more secure and convenient way to connect to MongoDB Atlas or other cloud-based MongoDB clusters.
