Day 3:Global infrastructure
AWS Cloud Practitioner with Neel Patel

Fault Tolerance
Fault tolerance refers to the ability of a system to continue operating in the event of the failure of some of its components. The scope of a fault domain can include:
Specific servers in a rack
An entire rack in a data center
An entire room in a data center
The entire data center building
The definition of a fault domain's boundaries is determined by the Cloud Service Provider (CSP), and AWS implements fault tolerance in various ways.
Amazon Region: Failure Zones
AWS regions are geographically isolated locations that contain multiple Availability Zones (AZs). By using Multi-AZ deployments, AWS ensures high availability and fault tolerance for your applications, allowing services to continue running even if one AZ goes down.
Amazon Global Network
AWS provides a vast, globally distributed network infrastructure to enhance performance, reliability, and fault tolerance for its users. Some key components include:
Points of Presence (PoPs)
AWS Points of Presence (PoPs) are strategically located facilities that host CloudFront edge locations and Route 53 DNS servers. PoPs enhance content delivery and reduce latency for end users worldwide.
Tier-1 Network
AWS's Tier-1 network refers to its status as a top-level Internet Service Provider (ISP). It is directly interconnected with all other Tier-1 networks, ensuring efficient and resilient global traffic routing.
AWS Direct Connect
AWS Direct Connect is a cloud service that establishes a dedicated, private network connection between your premises and AWS. This connection offers increased bandwidth throughput and a more consistent network experience compared to internet-based connections.
Global Infrastructure
AWS operates an extensive global infrastructure to support diverse use cases, ranging from low-latency applications to regulatory compliance.
Direct Connect Locations
AWS provides Direct Connect locations around the world where customers can establish dedicated network connections between their on-premises infrastructure and AWS, increasing bandwidth throughput and reducing network costs.
Local Zones
AWS Local Zones place compute, storage, and other select services closer to large population centers, industries, and IT centers, enabling low-latency applications for users in those areas.
Wavelength Zones
AWS Wavelength Zones embed AWS compute and storage services within telecommunications providers' data centers at the edge of the 5G network. This allows for reduced latency for mobile and connected devices.
Data Residency
AWS provides data residency solutions to help customers ensure their data remains within a specific geographic location to comply with regulatory and compliance requirements.
AWS for Government
AWS offers cloud services tailored for government customers, helping them achieve mission-critical objectives securely and efficiently.
GovCloud (U.S.)
AWS GovCloud (U.S.) regions are designed to host sensitive data and regulated workloads. These regions comply with government regulations such as ITAR and FedRAMP.
AWS China
AWS operates regions in China in partnership with local Chinese companies to comply with Chinese regulations, offering cloud services to customers within the country.
Sustainability
AWS is committed to sustainability, with a goal to power its operations with 100% renewable energy by 2025. AWS continuously works to improve energy efficiency and reduce its environmental impact.
AWS Ground Station
AWS Ground Station provides a fully managed service that lets customers control satellite communications, process data, and scale operations without having to build or manage their own ground station infrastructure.
AWS Outposts
AWS Outposts extends AWS infrastructure, services, APIs, and tools to virtually any data center or on-premises facility. This enables a truly consistent hybrid cloud experience for users who need both on-premises and cloud resource
