Becoming a Cloud Architect: A Roadmap to the AWS Solutions Architect - Associate Certificate🏗️💡

Hello Everyone! 😄

What should you be expecting from the Article?

Here, I will be presenting all the tips and tricks I used to prepare myself properly and pass the exams of the AWS Solutions Architect - Associate certificate.

This is my first post, so an feedback is more than welcome!😁


There are 4 Sections

  1. General Information - Information about the AWS resources and exams.
  2. Courses - What you need to know and how to proceed.
  3. Practice Tests - How should you utilize your time and resources.
  4. Appendix - Useful Resources w/ Tips & Tricks.

0. General Information 📝

The AWS Solutions Architect - Associate (or SAA-C03) is considered as a rather challenging certificate. It is a process that could take as much time as you want/need. To be honest though, you should set a goal of N days/months and schedule the exams for a certain day. As the time passes, it gets more difficult to remember all the information you gained during your homework.
Don't forget we are talking about nearly 150 AWS services that are in the exams.


Questions are descriptive and could get long, presenting an architectural scenario, for which you are asked to provide the most well suited answer from a multiple choice format.

  • Since the AI/ML Solutions are now a hot topic, the SAA-C03 release of the exams assimilate more questions on AWS's AI/ML services.

  • In these 65 questions, 15 of them are Unscored Questions. These questions will not affect your score. AWS randomly uses them in the exams, to gather information from each candidate and assess the worth of each question for future use.

  • Every time, try excluding the answers that seem to be off. Usually, you'll find two answers that do not actually stick with the questions, and two answers that are similar.

  • Never leave a question unanswered. Even if it doesn't make sense to you, I suggest that you answer the question, Flag it and revisit it, once you are done with all 65 of them. This way you'll get plenty more time to evaluate the question without getting anxious about the time.

There are 4 domains in which you'll prepare yourself, as described in the table below. This is just good to know, it doesn't make any difference to you.

Domain % of Exams
Domain 1: Design Secure Architecture 30%
Domain 2: Design Resilient Architectures 26%
Domain 3: Design High-Performing Architectures 24%
Domain 4: Design Cost-Optimized Architectures 20%

🔒 Domain 1 : Design Secure Architecture

Secure Architecture means Access Control, Global Infrastructure, Federated Access and Identity Services and Best Practices.

Outstanding Services: VPN, AWS Direct Connect, NAT Gateways, AWS WAF, and Security Groups.

⚖️ Domain 2 : Design Resilient Architecture

Resilient Architecture means scalable, fault-tolerant and loosely coupled, and highly available architectures.

Outstanding Services: SQS, SNS, AWS Lambda, AWS Fargate, Load Balancers (ALB, ELB, GLB), Amazon API Gateway, Secrets Manager, Amazon ECS, Amazon EKS, AWS Step Function, DR Strategies, Amazon Route 53, AWS Regions and Availability Zones

⚡ Domain 3 : Design High-Performing Architectures

High Performing Architecture means scalable and elastic database, compute and network solutions.

💰 Domain 4 : Design Cost-Optimized Architectures

Cost Optimized Architecture means using the most appropriate infrastructure, providing the best performance with the least cost.

Outstanding Services: AWS Cost Explorer, Cost Allocation Tags, Comparing identical services (i.e. Nat gateway/instance), Network routing/peering/topology (AWS Transit Gateway, VPC peering, Site-to-Site VPN, AWS Direct Connection), Spot Fleets/Instances, Comparing AWS database services, Comparing storage types (EBS, EFS, FSx, S3), S3 Bucket Tiers.


1. Courses 📙

First of all, you need to pick the course that makes the best fit for you. For my case, the course Ultimate AWS Certified Solutions Architect Associate SAA-C03 offered by Stephane Maarek in Udemy was ideal. Descriptive, well organized, with a great flow and hands-on labs. This is a long course with 27 hours of lectures.

NOTE: You do not need to go over the hands-on labs. Time and Cost-wise (as you would need to provision some AWS infrastructure that might not be included in the Free Tier). There is not doubt that this will help you elevate your understanding in AWS, but it is not actually required to prepare you for the exams. Practice tests are the experience you are looking, just for the exams.

Tip: For me it was helpful writing down notes of the services I had issues understanding.

2. Practice Tests 🧪

Practice Tests are actually what will get you through the exams. Without these, it would be (and without any experience in these exams) extremely difficult for anyone to pass the exams.
This is the hands-on experience you are looking for the exams.

NOTE: in October 2022 AWS released the new version of the exams, moving into SAA-C03 (previous was SAA-C02).

TIP: There are no big differences between the two versions, but AWS has included new services in SAA-C03, focusing on the AI/ML ones.

3. Appendix 🍬

Here you'll find resources to help you out through your preparation for the certificate, but also for your career as a AWS Solutions Architect.

  • AWS Product List - FAQs 🆘 - This probably is one of the most important one. The best resource you may utilize to gain a better understanding is the FAQs page of the service itself. As an AWS Solutions Architect you need to have at least a good understanding of these questions for the most popular services.

  • Abdur's Notes - This is a great blog for you to use as a reference point when you want to go back and check specific resources or just to make a revision. Those could be a little outdated, but still will do the job for you.

  • AWS Solutions - This is an index of solutions provided by AWS, which follow good practice principles, and can be used as additional labs/exercises.

  • AWS Well Architected - This is a resource that will help you out build and maintain solutions on top of the six pillars of AWS for Cloud systems.

  • AWS Blog - Consider this as AWS newsfeed. From here, you may keep yourself up-to-date with the latest trends/news of AWS from AWS.


Hopefully this will get you started with your studies on the exams. Again, please share if you have any other suggestions, tips or tricks!
