Assign custom metadata to your cluster using tags consisting of a key and a value, both of which you define. This is a convenient way to categorize your AWS resources in different ways (e.g. by purpose, owner, or environment). For example, you could define a set of tags for your account's clusters that helps you track each cluster's owner or identify a production cluster versus a testing cluster. It is recommended that you create a consistent set of tags to meet your organization requirements.





Your AWS region.

If enabled, Elastic IPs will be created for these servers.
