-- | This operation creates a new vault with the specified name. The name of the
-- vault must be unique within a region for an AWS account. You can create up to
-- 1,000 vaults per account. If you need to create more vaults, contact Amazon
-- Glacier.
--
-- You must use the following guidelines when naming a vault.
--
-- Names can be between 1 and 255 characters long.
--
-- Allowed characters are a-z, A-Z, 0-9, '_' (underscore), '-' (hyphen), and
-- '.' (period).
--
--
--
-- This operation is idempotent.
--
-- An AWS account has full permission to perform all operations (actions).
-- However, AWS Identity and Access Management (IAM) users don't have any
-- permissions by default. You must grant them explicit permission to perform
-- specific actions. For more information, see <http://docs.aws.amazon.com/amazonglacier/latest/dev/using-iam-with-amazon-glacier.html Access Control Using AWS Identityand Access Management (IAM)>.
