Section 1: AWS Global Infrastructure
- The AWS Global Infrastructure is designed and built to deliver a flexible, reliable, scalable and secure cloud computing environmnent with high-quality global network performance
AWS Region
An AWS Region is a geographical area
- Data replication across Regions is controlled by you
- Communication between Regions uses AWS backbone network infrastructure
- Each region provides full redundancy and connectivity to the network
- A region typically consists of two or more Availability Zone
Selecting a Region
- Might be legal requirements
- Local laws can restrict the Region
- Ex: European Union
- Latency
- Can test with Cloud Ping
- Not all AWS services are available depending on the region
Availability Zones
- Each Region has multiple Availabiity Zones
- Each Availability Zone is fully isolated partition of the AWS infrastructure
- 69 Availability Zones worldwide
- Availability Zones consist of discrete data centers
- Usually 3
- They are designed for fault isolation
- They are interconnected with other Availability Zones by using high-speed private networking
- Dedicated fiber
- You choose your Availability Zones
- AWS recommends replicating data and resources across Availability Zones for resiliency
- Protected for tornadoes, lightning, earthquakes…
AWS data centers
- AWS data centers are designed for security
- Data centers are where the data resides and data processing occurs
- Each data has redundant power, networking and connectivity, and is housed in a separate facility
- A data center typically has 50,000 to 80,000 physical servers
AWS uses custom netowrking equipment source from multiple ODMs.
ODM: Original Device Manufacturers
Design and manufacture product based on specifications from a second company. The second company rebrand the products for sale.
Points of Presence
- AWS provides a global network of 187 Points of Presence locations
- Consists of 176 edge locations and 11 Regional edge caches
- Used with Amazon CloudFront
- A global Content Delivery Network (CDN) that delivers content to end users with reduced latency
- Regional edge caches used for content with infrequent access
