-- | If specified, the deployment configuration name must be one of the
-- predefined values, or it can be a custom deployment configuration:
--
-- -   CodeDeployDefault.AllAtOnce deploys an application revision to up to
--     all of the instances at once. The overall deployment succeeds if the
--     application revision deploys to at least one of the instances. The
--     overall deployment fails after the application revision fails to
--     deploy to all of the instances. For example, for 9 instances, deploy
--     to up to all 9 instances at once. The overall deployment succeeds if
--     any of the 9 instances is successfully deployed to, and it fails if
--     all 9 instances fail to be deployed to.
-- -   CodeDeployDefault.HalfAtATime deploys to up to half of the instances
--     at a time (with fractions rounded down). The overall deployment
--     succeeds if the application revision deploys to at least half of the
--     instances (with fractions rounded up); otherwise, the deployment
--     fails. For example, for 9 instances, deploy to up to 4 instances at
--     a time. The overall deployment succeeds if 5 or more instances are
--     successfully deployed to; otherwise, the deployment fails. Note that
--     the deployment may successfully deploy to some instances, even if
--     the overall deployment fails.
-- -   CodeDeployDefault.OneAtATime deploys the application revision to
--     only one of the instances at a time. The overall deployment succeeds
--     if the application revision deploys to all of the instances. The
--     overall deployment fails after the application revision first fails
--     to deploy to any one instances. For example, for 9 instances, deploy
--     to one instance at a time. The overall deployment succeeds if all 9
--     instances are successfully deployed to, and it fails if any of one
--     of the 9 instances fail to be deployed to. Note that the deployment
--     may successfully deploy to some instances, even if the overall
--     deployment fails. This is the default deployment configuration if a
--     configuration isn\'t specified for either the deployment or the
--     deployment group.
--
-- To create a custom deployment configuration, call the create deployment
-- configuration operation.
