Study Notes

AWS Global Infrastructure

AWS infrastructure is designed for high-quality global network performance, reliability, scalability, and security.
An AWS Region is a geographical area.
Data replication between regions is managed by the user.
Communication between regions uses AWS backbone network infrastructure.
Each region offers complete redundancy and connectivity with high-speed private networking.
A Region typically includes two or more Availability Zones.
When selecting a region consider factors like data governance laws, customer proximity for reduced latency, availability of specific services, and cost.
Each Availability Zone is a completely separate AWS infrastructure partition.
There are currently 69 Availability Zones globally.
Availability Zones consist of distinct data centers.
Data centers are interconnected by high-speed private networking, ensuring fault isolation.
Data centers have redundant power, networking, and connectivity, housed in separate facilities.
Data centers hold data and process data, typically containing 50,000-80,000 physical servers.
AWS has a global network of 187 Points of Presence (PoPs).
176 edge locations enable end-user access to AWS services.
11 regional edge caches store frequent content close to users, utilizing Amazon CloudFront (CDN).
CloudFront securely delivers data, videos, applications, and APIs with fast speed and low latency using a developer-friendly environment.

AWS Infrastructure Features

Elasticity and scalability: Adapts to capacity and growth needs.
Fault-tolerance: Continues operation during component failure due to built-in redundancy.
High availability: Maintains high operational performance with minimal downtime, requiring no human intervention.

AWS Services and Service Category Overview

AWS has 23 different product or service categories.
The provided text focuses on common/foundation services.

AWS Storage Services

Amazon Simple Storage Service (S3): Object storage service known for scalability, availability, security, and performance.
Amazon Elastic Block Storage (EBS): High-performance block storage suitable for use with Amazon EC2, optimized for throughput and transaction-intensive workloads at any scale.
Amazon Elastic File System (EFS): Scalable NFS file system for use with AWS Cloud services and on-premises resources.
Amazon Simple Storage Service Glacier: Secure, durable, and cost-effective cloud storage for data archiving and long-term backups.

AWS Compute Services

Amazon EC2: Secure, scalable compute capacity in the cloud.
Amazon EC2 Auto Scaling: Ensures application availability; automatically adjusts EC2 instances based on defined conditions.
