AWS Global Infrastructure

A Look into AWS Global Infrastructure

The sources provide a detailed overview of the AWS Global Infrastructure, highlighting its key components and features.

The sources state that the AWS Global Infrastructure comprises Regions and Availability Zones:

Regions: These are separate geographical areas hosting multiple Availability Zones. They ensure low latency and data protection by offering services closer to users. For instance, India has the ‘AP South -1’ Region with Availability Zones in Mumbai and Hyderabad.
Availability Zones (AZs): AZs are distinct data centers within a Region. Each AZ is isolated with its own power, cooling, and networking to prevent service disruptions in case of failure in one AZ.

The sources emphasize the extensive reach and high availability of the AWS Global Infrastructure:

Worldwide Coverage: AWS Cloud spans 105 Availability Zones within 33 geographic regions across the globe. Plans are in place for 18 more Availability Zones and 6 more Regions.
High Network Availability: AWS claims to have the highest network availability among cloud providers, attributed to the isolated and fault-tolerant design of each Region with multiple AZs.

The sources highlight the robust security measures implemented by AWS:

Custom-Built Security Infrastructure: AWS has a custom-built security infrastructure designed specifically for the cloud. This infrastructure is monitored 24/7 to ensure data confidentiality, integrity, and availability.
Data Encryption: All data flow across the global network is encrypted, providing users with control over their data, including encryption, movement, and retention management.

The sources point out the flexibility and performance benefits offered by the AWS Global Infrastructure:

Choice and Control: AWS allows users to choose where and how they want to run their workloads, offering the same network, control plane, APIs, and services across its global infrastructure. This gives users the flexibility to choose the best location for their needs, considering factors like latency, cost, and compliance.
High Performance: The sources highlight the high-performance capabilities of AWS Global Infrastructure, mentioning its redundant 400 GbE fiber backbone that enables low latency, minimal packet loss, and excellent network quality.

The sources list some of the key components of the AWS Global Infrastructure:

AWS Data centers: Designed with robust security measures.
Availability Zones: Each region comprises multiple Availability Zones, designed for fault isolation.
Local Zones: Extend regions closer to end users, reducing latency.
CloudFront POPs: 600+ CloudFront Points of Presence (POPs) and 13 Regional edge caches contribute to content delivery optimization.

The sources outline key considerations for selecting a Region for deploying services, applications, and data:

Data Governance and Legal Requirements: Factors like GDPR compliance influence region selection.
Proximity to Customers: Reducing latency by choosing a Region closer to the target audience is crucial.
Available Services: The range of services offered within a Region impacts the choice.
Cost: Pricing variations across regions play a significant role in decision-making.
