AWS Global Services Explained: Route 53 and IAM

Introduction

Most AWS services are regional, but some important services are global.

Regional vs Global Services

Route 53

Route 53 is AWS's DNS service. Because DNS operates globally, Route 53 is considered a global service.

IAM

IAM stands for Identity and Access Management.

IAM manages users, groups, roles, and permissions.

Because identities must work across Regions, IAM is a global service.

Key Takeaways

• Most AWS services are regional.
• Route 53 is a global DNS service.
• IAM is a global identity service.
• Global services do not require Region selection.
