Description: A global resource in AWS CloudFormation refers to those resources that are accessible from any region within the Amazon Web Services infrastructure. This means that regardless of the region in which a CloudFormation template is deployed, the global resource can be used and referenced. Global resources are fundamental for architectures that require high availability and resilience, as they allow developers and solution architects to implement configurations that transcend geographical limitations. Examples of global resources include Amazon Route 53, which is a DNS service, and AWS IAM (Identity and Access Management), which allows for the management of users and permissions at a global level. The ability to access these resources from any region facilitates the creation of distributed applications and the implementation of disaster recovery strategies, thereby optimizing operational efficiency and the end-user experience. In summary, global resources in CloudFormation are essential for building scalable and robust solutions in the AWS cloud.
