| Exam Domain | Weight | Key Topics |
|---|---|---|
| Resilient Architectures | 30% | Multi-AZ, backups, decoupling |
| High-Performing Architectures | 30% | Caching, scaling, performance tiers |
| Secure Architectures | 30% | Encryption, IAM, security groups |
| Cost-Optimized Architectures | 10% | Spot instances, S3 tiers, RI |

Essential Services to Master
The AWS Solutions Architect exam requires deep understanding of numerous services. Here are the most critical services you must know thoroughly to pass the exam.
1. Amazon S3 (Simple Storage Service)
S3 is object storage built to store and retrieve any amount of data from anywhere on the web. It provides 99.999999999% durability and supports various storage classes including Standard, Intelligent-Tiering, Glacier, and more.
S3 Storage Classes
Understanding when to use Standard vs Glacier vs Intelligent-Tiering is crucial for cost optimization questions on the exam.
2. Amazon VPC (Virtual Private Cloud)
VPC lets you provision a logically isolated section of the AWS cloud where you can launch AWS resources in a virtual network that you define. You have complete control over your virtual networking environment.
3. Amazon RDS (Relational Database Service)
RDS makes it easy to set up, operate, and scale a relational database in the cloud. It supports popular engines like MySQL, PostgreSQL, Oracle, SQL Server, and Aurora.
4. Amazon EC2 (Elastic Compute Cloud)
EC2 provides scalable computing capacity in the AWS cloud. Understanding instance types, pricing models (On-Demand, Reserved, Spot), and placement groups is essential for the exam.
5. AWS Lambda
Lambda lets you run code without provisioning or managing servers. You pay only for the compute time you consume. This is key for building serverless architectures.
