-- Stops a specific Amazon Lightsail instance that is currently running.
--
-- When you start a stopped instance, Lightsail assigns a new public IP
-- address to the instance. To use the same IP address after stopping and
-- starting an instance, create a static IP address and attach it to the
-- instance. For more information, see the
-- <https://lightsail.aws.amazon.com/ls/docs/en_us/articles/lightsail-create-static-ip Amazon Lightsail Developer Guide>.
--
-- The @stop instance@ operation supports tag-based access control via
-- resource tags applied to the resource identified by @instance name@. For
-- more information, see the
-- <https://lightsail.aws.amazon.com/ls/docs/en_us/articles/amazon-lightsail-controlling-access-using-tags Amazon Lightsail Developer Guide>.
