How Does AWS Work?

AWS works by providing access to virtualized IT infrastructure over the internet. Here's a breakdown of its core functioning:

1. Infrastructure and Services:

   • AWS has data centres worldwide, divided into Regions and Availability Zones for redundancy and scalability.
   • Users can choose services based on location for low latency and data compliance requirements.

2. Services Categories: AWS offers numerous services, including:

   • Compute: EC2 (virtual servers), Lambda (serverless computing).
   • Storage: S3 (object storage), EBS (block storage), Glacier (archival storage).
   • Databases: RDS (relational database), DynamoDB (NoSQL database).
   • Networking: VPC (Virtual Private Cloud), Route 53 (DNS).
   • AI/ML: SageMaker, Rekognition, Translate.
   • Security: IAM (Identity and Access Management), Shield (DDoS protection).

3. Operation:

   • Customers interact with AWS services via a web interface, CLI (Command Line Interface), or APIs.
   • Services are billed based on usage (e.g., time, data transfer, or resource consumption).
   • Resources can be easily scaled up or down based on demand, offering flexibility and cost efficiency.

4. Reliability and Redundancy:

   • Built-in features like load balancing, failover, and multiple availability zones ensure high availability and reliability.
