This lesson explores the AWS services deployed across core accounts and their roles in supporting e-commerce use cases. It highlights best practices, their roles within the account, and how they interact with various layers of an e-commerce architecture, such as presentation, business logic, and data layers.

SharedServices Account

This account hosts shared infrastructure components used across all environments, ensuring reusability, cost efficiency, and streamlined management.

• AWS CodePipeline,

• CodeBuild

• CodeDeploy

• Amazon ECR

• Amazon S3, AWS CodeArtifact

SecurityTooling Account

This account centralizes security monitoring, compliance, and threat detection tools.

• Amazon Security Hub

• Amazon GuardDuty

• Amazon Macie

• AWS Config

LogArchive Account

Central repository for logs from all accounts, critical for audit and analysis.

• AWS CloudTrail

• Amazon S3 (Logs Storage)

• Amazon OpenSearch and QuickSight

Workload Accounts

These accounts host application workloads segregated by environment.
