AWS Global Infrastructure and Services Review

Practice flashcards covering AWS Global Infrastructure, location-based migration factors, cost optimization, and VPC components.

Data Residency & Compliance

Regulatory requirements that may mandate data stays within specific geographic boundaries, such as GDPR in Europe, HIPAA in the U.S., or data localization laws in India.

CloudPing.info

A tool used to test latency between different AWS regions.

AWS Region

A large geographic area where AWS has multiple data centers, isolated from one another for security and fault tolerance.

Availability Zone (AZ)

One or more physically separate, discrete data centers within an AWS Region, each with redundant power, cooling, and networking.

Regional Endpoint

The URL used to access an AWS service via the CLI or API, such as $https://dynamodb.us-west-2.amazonaws.com$ for Amazon DynamoDB.

AZ ID

A unique identifier used to accurately identify the same physical Availability Zone across different AWS accounts.

AWS Local Zones

Extensions of an AWS Region placed closer to major metropolitan areas to provide single-digit millisecond latency for applications like gaming or financial services.

AWS Edge Locations

Data centers used by Amazon CloudFront (CDN) to cache frequently accessed content (images, videos, etc.) closer to users.

Regional Edge Caches

Infrastructure that sits between the origin server and Edge Locations, featuring larger caches to store less frequently accessed content.

AWS Wavelength Zones

AWS infrastructure deployed inside telecommunications providers' data centers at the edge of $5G$ networks to provide ultra-low latency for mobile applications.

AWS Outposts

A service that extends AWS Cloud hardware, services, and APIs to on-premises data centers, co-location spaces, or facilities for a consistent hybrid experience.

AWS Global Accelerator

A service that uses Anycast IP addresses and the AWS global network to route users to the best and healthiest AWS Region.

AWS Shield

A security service specifically designed to protect applications from DDoS attacks.

AWS WAF

A Web Application Firewall that protects web applications from common web attacks.

Lambda@Edge

A feature that runs AWS Lambda functions at CloudFront Edge Locations for customizing content or manipulating HTTP headers.

Amazon Route 53

AWS's Domain Name System (DNS) service that translates domain names into IP addresses and supports health checks and traffic management.

Route 53 Resolver DNS Firewall

A feature that blocks DNS requests to known or suspected malicious domains while allowing trusted domains.

AWS Well-Architected Framework

A set of best practices provided by AWS for efficient cloud architecture and cost optimization.

Amazon VPC (Virtual Private Cloud)

A logically isolated virtual network in AWS that works like a private network in a traditional data center.

Subnet

A range of IP addresses within a VPC that exists in only one Availability Zone.

Internet Gateway (IGW)

A VPC component that provides a connection between the VPC and the internet.

VPC Peering

A networking connection that allows two VPCs to communicate with each other privately.

Transit Gateway

A central hub used to connect multiple VPCs, VPNs, and Direct Connect links.

VPC Flow Logs

A feature used to capture information about IP traffic entering and leaving a VPC for monitoring and security.

Elastic IP (EIP)

A static public IPv4 address assigned to an AWS resource.
