-- | If specified, the deployment configuration name can be either one of the
-- predefined configurations provided with AWS CodeDeploy or a custom
-- deployment configuration that you create by calling the create
-- deployment configuration operation.
--
-- CodeDeployDefault.OneAtATime is the default deployment configuration. It
-- is used if a configuration isn\'t specified for the deployment or the
-- deployment group.
--
-- The predefined deployment configurations include the following:
--
-- -   __CodeDeployDefault.AllAtOnce__ attempts to deploy an application
--     revision to as many instance as possible at once. The status of the
--     overall deployment will be displayed as __Succeeded__ if the
--     application revision is deployed to one or more of the instances.
--     The status of the overall deployment will be displayed as __Failed__
--     if the application revision is not deployed to any of the instances.
--     Using an example of nine instance, CodeDeployDefault.AllAtOnce will
--     attempt to deploy to all nine instance at once. The overall
--     deployment will succeed if deployment to even a single instance is
--     successful; it will fail only if deployments to all nine instance
--     fail.
--
-- -   __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 is deployed to at
--     least half of the instances (with fractions rounded up); otherwise,
--     the deployment fails. In the example of nine instances, it will
--     deploy to up to four instance at a time. The overall deployment
--     succeeds if deployment to five or more instances succeed; otherwise,
--     the deployment fails. The deployment may be successfully deployed to
--     some instances even if the overall deployment fails.
--
-- -   __CodeDeployDefault.OneAtATime__ deploys the application revision to
--     only one instance at a time.
--
--     For deployment groups that contain more than one instance:
--
--     -   The overall deployment succeeds if the application revision is
--         deployed to all of the instances. The exception to this rule is
--         if deployment to the last instance fails, the overall deployment
--         still succeeds. This is because AWS CodeDeploy allows only one
--         instance at a time to be taken offline with the
--         CodeDeployDefault.OneAtATime configuration.
--
--     -   The overall deployment fails as soon as the application revision
--         fails to be deployed to any but the last instance. The
--         deployment may be successfully deployed to some instances even
--         if the overall deployment fails.
--
--     -   In an example using nine instance, it will deploy to one
--         instance at a time. The overall deployment succeeds if
--         deployment to the first eight instance is successful; the
--         overall deployment fails if deployment to any of the first eight
--         instance fails.
--
--     For deployment groups that contain only one instance, the overall
--     deployment is successful only if deployment to the single instance
--     is successful
