--
-- The /AddTagsToResource/ action adds up to 10 cost allocation tags to the
-- named resource. A /cost allocation tag/ is a key-value pair where the
-- key and value are case-sensitive. Cost allocation tags can be used to
-- categorize and track your AWS costs.
--
-- When you apply tags to your ElastiCache resources, AWS generates a cost
-- allocation report as a comma-separated value (CSV) file with your usage
-- and costs aggregated by your tags. You can apply tags that represent
-- business categories (such as cost centers, application names, or owners)
-- to organize your costs across multiple services. For more information,
-- see
-- <http://docs.aws.amazon.com/AmazonElastiCache/latest/UserGuide/Tagging.html Using Cost Allocation Tags in Amazon ElastiCache>.
