# AWS Global Infrastructure

* AWS Regions are the main data centers in a particular geography.
* AWS Regions are further divided into availability zones by default that are there for fail-over and high availability. Example: ap-south-1 is Region Name and ap-south-1a is availability zone.
* AWS Local Zones can be said as an extension of AWS Region. They are just strategically located AWS data center which is well connected with main AWS Region Data Center.
* Outside of AWS Regions, specific points of presence elements exist. They are Edge Locations and Regional Edge Caches. Edge Locations are nodes used by Content Delivery Network service of AWS, named as Amazon CloudFront and their DNS service named as Amazon Route 53.
