What is the meaning of wildcard in cloud computing?

In cloud computing, a wildcard is a character or string used in search queries or configurations to represent one or more unspecified characters or values. It allows for flexible matching in tasks such as filtering resources, managing access permissions, or defining patterns in data retrieval. For example, using an asterisk (*) as a wildcard can enable users to match multiple items in a cloud storage service or in firewall rules. This helps simplify tasks by reducing the need for explicitly listing every possible option.
