AWS Global Infrastructure Explorer

AWS Regions Directory

Explore all AWS regions and their characteristics. Each region is designed to be completely independent, allowing you to choose where to deploy based on your requirements.

Choosing the Right Region

Latency: Choose regions closest to your users for best performance.

Compliance: Some regulations require data to stay in specific countries/regions.

Service Availability: Not all services are available in all regions immediately.

Pricing: Costs can vary between regions based on local infrastructure expenses.

Understanding AWS Infrastructure Concepts

Master the fundamental concepts that make AWS's global infrastructure reliable, scalable, and performant.

What is a Region?

A Region is a physical location around the world where AWS clusters data centers. Each Region consists of multiple, isolated, and physically separate Availability Zones within a geographic area.

• Fully independent and isolated from other regions
• Contains multiple Availability Zones (typically 3 or more)
• You choose which region to deploy resources in
• Data doesn't leave a region unless you explicitly transfer it
• Each region has its own pricing

What is an Availability Zone?

An Availability Zone (AZ) is one or more discrete data centers with redundant power, networking, and connectivity in an AWS Region.

• Each AZ is isolated from failures in other AZs
• Connected via high-bandwidth, low-latency networking
• Physically separated (miles/kilometers apart)
• Deploy across multiple AZs for high availability
• Each AZ has independent infrastructure

What are Edge Locations?

Edge Locations are AWS sites deployed in major cities and highly populated areas to cache content closer to end users via Amazon CloudFront CDN.

• Used for content delivery (CloudFront)
• DNS service delivery (Route 53)
• More numerous than regions
• Reduce latency for end users
• Don't run your EC2 instances

High Availability Architecture

Best Practices for High Availability

Deploy across multiple AZs: Always use at least 2 AZs for production workloads.

Use managed services: Services like RDS, ELB, and S3 automatically use multiple AZs.

Design for failure: Assume any component can fail and architect accordingly.

Multi-region for DR: For critical applications, replicate to another region for disaster recovery.

Local Zones and Wavelength Zones

Local Zones

AWS Local Zones place compute, storage, database, and other select services closer to large population centers and industry hubs.

• Extension of an AWS Region
• Single-digit millisecond latency to end users
• Located in metro areas (LA, Boston, Miami, etc.)
• Perfect for latency-sensitive applications
• Supports subset of AWS services

Wavelength Zones

AWS Wavelength embeds AWS compute and storage services within 5G networks, providing ultra-low latency for mobile edge computing.

• Deployed at telecom providers' 5G networks
• Sub-10 millisecond latency to mobile devices
• Ideal for mobile gaming, AR/VR
• Real-time video processing
• Connected to parent AWS Region

AWS Outposts

AWS Outposts brings native AWS services, infrastructure, and operating models to virtually any data center, co-location space, or on-premises facility.

• Fully managed infrastructure
• Run AWS services on-premises
• Same APIs and tools as AWS
• For data residency requirements
• Low-latency access to on-prem systems

AWS Edge Network

AWS operates a global network of edge locations and Points of Presence (PoPs) to deliver content and services with the lowest latency possible.

Services Using Edge Locations

Amazon CloudFront: Content Delivery Network (CDN) that caches content at edge locations for fast delivery.

Amazon Route 53: DNS service that routes users to the nearest edge location for low-latency name resolution.

AWS Shield: DDoS protection that operates at edge locations to absorb attacks before they reach your infrastructure.

AWS WAF: Web Application Firewall deployed at edge locations to filter malicious traffic.

Edge Location Benefits

Reduced Latency: Content is served from the geographically closest edge location to users.

Improved Performance: Static and dynamic content is cached, reducing load on origin servers.

DDoS Protection: Traffic is distributed across edge locations, absorbing attacks.

Cost Savings: Reduced data transfer from origin servers and bandwidth costs.
