An Elastic IP address in AWS is defined as a static IPv4 address that is allocated for use with cloud computing environments. This address allows users to maintain a consistent public-facing IP address even if the underlying infrastructure changes, such as when an instance is stopped and started or if it needs to be re-assigned to different instances.

The significance of Elastic IP addresses lies in their ability to enhance the management of cloud resources. They provide reliability in communication with customers, as the public IP remains constant, enabling seamless connectivity for applications and services hosted on AWS.

The other options do not accurately describe the nature of Elastic IP addresses. For instance, a dynamic IP address assigned to instances is a different concept, typically associated with the automatic assignment of IP addresses by AWS, which can change when instances restart. Additionally, Elastic IP addresses function in the public cloud context and are not limited to private cloud operations. Lastly, while Elastic IP addresses can be used by instances running databases, they are not restricted solely to database connections; they serve any service or application needing a reliable public IP address.
