AWS Certified Cloud Practitioner - Learn Cloud Basics

AWS Cloud Infrastructure

AWS operates a global cloud infrastructure designed to support applications and services across different geographic locations. Understanding the basic AWS global infrastructure is an important part of Cloud Practitioner learning.

AWS Regions represent geographic areas where AWS operates infrastructure. Each Region contains multiple Availability Zones, which are designed to provide separate infrastructure locations within the same Region.

This architecture supports highly available applications. Organizations can distribute workloads across Availability Zones to reduce the impact of individual infrastructure failures.

Understanding Regions and Availability Zones helps beginners appreciate how AWS supports reliability and global application deployment.

Core AWS Services

AWS provides hundreds of cloud services, but Cloud Practitioner learners begin with the most important service categories.

Amazon EC2 provides virtual computing capacity in the cloud. It allows organizations to run applications on virtual servers without purchasing physical hardware.

Amazon S3 provides object storage for files, documents, images, backups, application data, and other objects. It is designed for scalable and durable storage.

Amazon RDS provides managed relational database capabilities, helping organizations run databases without managing all underlying infrastructure manually.

Amazon VPC enables organizations to create isolated virtual networks in AWS and control network communication between resources.

AWS Lambda provides serverless computing, allowing developers to execute code without managing traditional servers.
