-The Cloud Free Tier interface works much in the same way as the Docker
-interface, although it doesn't support as many features. To start a
-server in the Cloud Free Tier, you use the following:
-
-.. sourcecode:: python
-
-
-   from singlestoredb.server import free_tier
-
-   s2db = free_tier.start()
-
-   with s2db.connect() as conn:
-       with conn.cursor() as cur:
-           cur.execute('SHOW DATABASES')
-           for line in cur:
-               print(line)
-
-   s2db.stop()
-
-Just as with the Docker interface, you can also use a Python
-context manager to automatically shut down your connection.
