Where My AWS Journey Began

My journey into cloud computing didn’t begin with a computer science degree. In the mid of 2019, I completed a data science bootcamp that sparked my interest in cloud technology. Over the years I have worked with AWS extensively developing backend systems, building data pipelines and deploying scalable applications. These hands-on experiences gave me the confidence to attempt the AWS Certified Solutions Architect Associate (SAA-C03) exam.

Working daily with Amazon EC2, S3, RDS, Elastic Load Balancing and serverless tools such as AWS Lambda and API Gateway has been an important part of my professional routine. I also frequently used CloudFormation and IAM for automation and security management. This practical exposure helped me understand how AWS services integrate to form resilient, secure, and cost-efficient architectures.

After earning my AWS Certified Developer Associate certification I decided to deepen my architectural knowledge by pursuing the SAA-C03 certification. My long-term goal is to complete the AWS Solutions Architect Professional certification to expand my expertise in designing large-scale systems.

My Preparation Strategy

I began my preparation by watching the AWS Certified Solutions Architect Associate Course by Andrew Brown on YouTube. I found it through the FreeCodeCamp channel, which I’ve trusted for years. The course provided a structured approach that combined theoretical explanations with practical demonstrations. I replicated every hands-on lab in my own AWS account, staying within the free tier whenever possible.

After completing the course, I shifted my focus to practice tests to strengthen my problem-solving skills. For this I used Study4Exam’s free aws certified solutions architect associate exam practice questions​ which turned out to be one of the most valuable resources in my preparation.

What I liked about Study4Exam’s materials was how the questions were slightly more challenging than the actual exam. Each question came with detailed explanations, breaking down why each option was correct or incorrect. This approach helped me grasp the reasoning behind AWS architecture choices instead of relying on memorization.

Here’s how I organized my study routine:

1. Daily Learning Schedule: I dedicated two hours each morning to watch lectures or review AWS documentation followed by an hour of hands-on lab work.

2. Create Daily Flashcards: I created digital flashcards for every new service or architectural concept I encountered. Reviewing them daily helped reinforce important details such as service limits, pricing models and best practices.

3. Practice Tests Every Evening: I took at least one full-length test from Study4Exam each day. After every attempt I carefully reviewed the answers and studied the explanations until I fully understood the concepts.

Understanding the Exam Domains

The AWS Certified Solutions Architect Associate (SAA-C03) exam evaluates your ability to design secure, scalable and cost-efficient cloud solutions. It is divided into four key domains, and you need to score at least 720 out of 1000 to pass.

1. Domain 1: Design Secure Architectures

2. Domain 2: Design Resilient Architectures

3. Domain 3: Design High-Performing Architectures

4. Domain 4: Design Cost-Optimized Architectures

The most challenging area for me was Cost-Optimized Architectures. Choosing between Spot Instances, Savings Plans and Reserved Instances in different scenarios can be tricky. To master this I spent extra time reviewing AWS pricing documentation and re-taking related questions on Study4Exam until I became confident.

Key Lessons and Advice for Candidates

1. Take Your Time and Stay Consistent
If you’re new to AWS, don’t rush. I had prior AWS experience, which helped me prepare in about a month, but two to three months of consistent study is ideal. Consistency matters more than speed.

2. Focus on Hands-On Practice
You can watch as many lectures as you want, but nothing replaces practical experience. Create resources, configure IAM roles, deploy Lambda functions, and experiment with S3 and CloudFront. The more you practice, the more natural AWS feels during the exam.

3. Use Study4Exam for Practice
Study4Exam’s AWS Solutions Architect Associate Practice Tests are an excellent simulation of the real exam. The detailed explanations teach you how to think like an AWS architect rather than just memorize facts.

4. Learn the Why Behind Each Service
AWS questions often present multiple correct answers. The key is to choose the most appropriate one based on performance, cost, and fault tolerance. Always ask yourself why a particular service or design is better for a given scenario.

5. Keep a Healthy Study Routine
Preparing for the SAA-C03 can be intense. Take breaks, stay hydrated, and keep your daily routine balanced. Enjoy the learning process, because every new concept adds real-world value to your career.

My Exam Day Experience

On the day of the exam I felt prepared but slightly nervous. The actual questions were scenario-based, requiring deep understanding rather than memorized knowledge. I managed my time carefully, marking questions I wasn’t sure about for review. When I submitted the test, I felt confident and later that day, I saw the “Pass” result on my screen. It was one of the most satisfying moments of my AWS journey.

Final Thoughts

Passing the AWS Certified Solutions Architect Associate (SAA-C03) exam strengthened my ability to design secure and scalable solutions using AWS services. The certification not only boosted my confidence but also validated years of practical experience in the cloud.

If you’re preparing for this exam, I highly recommend using Study4Exam as your main practice platform. Their realistic exam questions and clear explanations provide the right level of challenge to get you fully ready for the real test.

Stay consistent, practice regularly and most importantly, enjoy the process. The SAA-C03 certification is not just a credential, it’s a meaningful step toward mastering AWS architecture.
