-- Requests remote access to a fleet instance. Remote access is useful for
-- debugging, gathering benchmarking data, or observing activity in real
-- time.
--
-- To remotely access an instance, you need credentials that match the
-- operating system of the instance. For a Windows instance, GameLift
-- returns a user name and password as strings for use with a Windows
-- Remote Desktop client. For a Linux instance, GameLift returns a user
-- name and RSA private key, also as strings, for use with an SSH client.
-- The private key must be saved in the proper format to a @.pem@ file
-- before using. If you\'re making this request using the CLI, saving the
-- secret can be handled as part of the @GetInstanceAccess@ request, as
-- shown in one of the examples for this operation.
--
-- To request access to a specific instance, specify the IDs of both the
-- instance and the fleet it belongs to. You can retrieve a fleet\'s
-- instance IDs by calling
-- <https://docs.aws.amazon.com/gamelift/latest/apireference/API_DescribeInstances.html DescribeInstances>.
