Tag is metadata of a resource; allow up to 50 tag per resource.

Why tagging resource

Reporting: in AWS console or billing reports
Management: tools like Stax use tags to group and classify your cloud data
Permissions: can restrict permission based on tag data
Filtering: AWS Resource Groups allow the console to be filtered based on tag
Automated Processes: used to drive scheduled shutdowns, backup policies, or AWS config policies
