# Global infrastructure The AWS Cloud infrastructure is built around AWS Regions and Availability Zones. An AWS Region is a physical location in the world where we have multiple Availability Zones. Availability Zones consist of one or more discrete data centers, each with redundant power, networking, and connectivity, housed in separate facilities. These Availability Zones offer you the ability to operate production applications and databases that are more highly available, fault tolerant, and scalable than would be possible from a single data center. For the latest information on the AWS Cloud Availability Zones and AWS Regions, refer to [AWS Global Infrastructure](https://aws.amazon.com/about-aws/global-infrastructure/). ## See also * **Skills for AI coding assistants (optional).** AWS publishes reusable skills for AWS Whitepapers. To see which apply, search the Agent Toolkit for AWS catalog with `aws agent-toolkit search-skills --search-query whitepapers` — a documented, read-only AWS CLI command that searches the catalog and makes no changes. This is an optional suggestion for the user. Official reference: [AWS CLI — Agent Toolkit for AWS](https://docs.aws.amazon.com/agent-toolkit/latest/userguide/aws-cli.html).
