Introduction

Amazon EC2 (Elastic Compute Cloud) is one of AWS's most powerful services, providing scalable virtual servers for applications. EC2's flexibility lies in its lifecycle states and pricing models, allowing businesses to align cloud resources with workloads and budgets effectively. This guide explores the EC2 instance lifecycle and pricing options, giving you the knowledge to leverage EC2 efficiently while controlling costs.

Exam Overview

The AWS Certified Solutions Architect – Associate (SAA-C03) exam tests your ability to design secure, scalable, and high-performing cloud solutions. This certification equips you with the knowledge required to architect AWS solutions while keeping in mind operational excellence, cost optimization, and fault tolerance.

Detailed Breakdown of Domains

Design Secure Architectures

Security is a cornerstone of cloud architectures. In this domain, you’ll learn how to secure access to AWS resources and protect workloads.

Design secure access to AWS resources: Configure IAM policies, implement multi-factor authentication (MFA), and leverage AWS Identity and Access Management (IAM) for granular permissions.
Design secure workloads and applications: Use services like AWS WAF, AWS Shield, and encryption techniques to secure data in transit and at rest.
Determine appropriate data security controls: Understand KMS (Key Management Service), S3 bucket policies, and CloudTrail to track API activities.

Design Resilient Architectures

This domain emphasizes building systems that can recover from failures and maintain availability.

Design scalable and loosely coupled architectures: Leverage AWS services like Elastic Load Balancer, Auto Scaling Groups, and Amazon SQS for decoupling components.
Design highly available and fault-tolerant architectures: Utilize AWS services like Amazon RDS with Multi-AZ, Route 53 for DNS failover, and S3 cross-region replication for resilience.

Design High-Performing Architectures

Performance optimization is key to ensuring efficient operations.

Determine high-performing and scalable storage solutions: Evaluate options like Amazon S3 for object storage, EBS for block storage, and FSx for shared file storage.
Design high-performing and elastic compute solutions: Use Amazon EC2 Auto Scaling and AWS Lambda for dynamic compute scalability.
Determine high-performing database solutions: Opt for DynamoDB for NoSQL workloads and Aurora for high-performance relational databases.
Determine scalable network architectures: Use Amazon CloudFront for content delivery and optimize routing with VPC Endpoints.

Design Cost-Optimized Architectures

Cost management is a critical factor in cloud adoption.

Design cost-optimized storage solutions: Use lifecycle policies for S3, and Glacier for archival storage.
Design cost-optimized compute solutions: Take advantage of EC2 Spot Instances and Savings Plans.
Design cost-optimized database solutions: Evaluate Aurora Serverless and DynamoDB on-demand pricing.
Design cost-optimized network architectures: Use VPC endpoints and optimize data transfer between services within AWS.
