AWS Global Infrastructure

Provides the physical and network foundation for delivering cloud services around the world

AWS Region

Is a separate geographic area in which AWS operates cloud infrastructure.

Regions

Are isolated from one another to support fault tolerance and stability

Availability Zone (AZ)

Is an isolated location within an AWS Region

This is designed for fault isolation and are connected to other Availability Zones in the same Region through high-bandwidth, lowlatency private networking.

AWS data centers

Are the physical facilities in which computing, storage, and network processing occur.

• Customers do not select a specific data center when deploying resources; the Availability Zone is generally the most granular infrastructure location that customers choose

AWS Points of Presence

Extend selected AWS services closer to end users. Unlike Regions and Availability Zones, ______ are designed primarily to reduce latency by bringing content and network services closer to users.

They include edge locations and Regional edge caches

Edge locations

Are used by services such as Amazon CloudFront and Amazon Route 53 to serve requests closer to end users and reduce latency

Amazon CloudFront

Is a content delivery network (CDN) that uses edge locations to deliver content with low latency and high transfer speeds

Regional edge caches

Provide an additional caching layer for content that is not accessed frequently enough to remain at an edge location

Foundational services

______ such as compute, networking, and storage use this infrastructure, while higher-level database, analytics, application, management, security, and other service categories build on those foundations
