Domain Breakdown: AWS Certified Solutions Architect Associate (SAA-C03)
The SAA-C03 exam evaluates your ability to design solutions based on the AWS Well-Architected Framework. It is structured around four primary domains:
| Exam Domain | Domain Description | Weighting (%) |
|---|---|---|
| Domain 1 | Design Secure Architectures | 30% |
| Domain 2 | Design Resilient Architectures | 26% |
| Domain 3 | Design High-Performing Architectures | 24% |
| Domain 4 | Design Cost-Optimized Architectures | 20% |

Phase 1: Core Fundamentals & Cloud Principles
Time Required: 3 to 4 Weeks (8–10 hours/week)
Objective: Master core cloud concepts, global infrastructure design, fundamental security primitives, and basic compute/networking constructs.
Before designing complex cloud architectures, you must understand the foundational building blocks of Amazon Web Services. This phase focuses on global infrastructure—Regions, Availability Zones (AZs), Local Zones, and Edge Locations—along with core governance and compute options.
Key Concepts to Master
Tip: Do not write code or deploy production resources using your AWS Root Account. Immediately create an IAM user with administrative permissions, enable MFA on both Root and IAM accounts, and set up an AWS Billing Alarm via CloudWatch.

Phase 2: Intermediate Tools, Networking & Clean Infrastructure
Time Required: 5 to 6 Weeks (10–12 hours/week)
Objective: Master Virtual Private Clouds (VPC), relational and non-relational database architectures, decoupling mechanisms, and Infrastructure as Code (IaC).
Phase 2 transitions you into true architectural design. The centerpiece of the SAA-C03 study guide is Virtual Private Cloud (VPC) design. You must be able to design secure, isolated network topology using public and private subnets, NAT Gateways, Internet Gateways, Route Tables, and Network Access Control Lists (NACLs).

Important: Network Access Control Lists (NACLs) are stateless (return traffic must be explicitly allowed), whereas Security Groups are stateful (return traffic is automatically allowed). This distinction is a frequent topic on the exam.
