Hands-on Lab: No
Assignment: No
πΌ Business Value
Section titled βπΌ Business ValueβAs organizations grow, a single AWS account becomes difficult to manage.
Different teams require different permissions, billing needs, compliance requirements and security controls.
To solve these challenges, AWS provides AWS Organizations, allowing enterprises to securely manage multiple AWS accounts under a single management account.
This enables:
- Better security
- Centralized governance
- Cost management
- Regulatory compliance
- Operational scalability
π’ In the Company
Section titled βπ’ In the CompanyβCloudNova Technologies started with a single AWS account.
As the business expanded, new teams began deploying cloud workloads:
- Development
- QA
- DevOps
- Security
- Data Engineering
- AI Engineering
Soon, everyone was sharing the same AWS account.
This created several problems:
- Production resources mixed with development resources.
- Developers accidentally modifying production infrastructure.
- Difficult cost tracking.
- Shared IAM permissions.
- Increased security risks.
The Cloud Security Team decided to redesign the environment using AWS Organizations and a multi-account strategy.
Throughout this module, you will help build CloudNovaβs enterprise AWS environment.
π What Youβll Learn
Section titled βπ What Youβll LearnβDuring this module you will learn:
- Why enterprises use multiple AWS accounts.
- AWS Organizations fundamentals.
- Organizational Units (OUs).
- Service Control Policies (SCPs).
- AWS Control Tower.
- Enterprise governance.
- Multi-account architecture.
Rather than configuring individual IAM users and roles, you will focus on how large enterprises organize and secure hundreds of AWS accounts.
