AWS Solutions Architect content domain outline

Domain 1: Design Resilient Architectures - 30%

1.1 Design a multi-tier architecture solution 1.2 Design highly available and/or fault-tolerant architectures 1.3 Design decoupling mechanisms using AWS services 1.4 Choose appropriate resilient storage

(SAA-C02) Exam Guide

The first domain requires you to understand how to build effective architectures using fundamental AWS services like EC2, VPC, RDS, S3, etc. Best practices are important to know when building these architectures, so it's good to understand the AWS Well-Architected Framework.

Domain 2: Design High-Performing Architectures - 28%

2.1 Identify elastic and scalable compute solutions for a workload 2.2 Select high-performing and scalable storage solutions for a workload 2.3 Select high-performing networking solutions for a workload 2.4 Choose high-performing database solutions for a workload

(SAA-C02) Exam Guide

The focus in this domain lies in building resilient architectures that make use of Scalability and Elasticity. You need to be able to understand the purpose of implementing Multi-AZ and Auto-Scaling to drive costs down and improve fault tolerance.

Domain 3: Design Secure Applications and Architectures - 24%

3.1 Design secure access to AWS resources 3.2 Design secure application tiers 3.3 Select appropriate data security options

(SAA-C02) Exam Guide

For the third domain, you're required to understand how to add security measures on four different levels: AWS resources, network-, application- and data-layer. The data layer can be distinguished into two parts, data in transit and data at rest. For data security encryption plays a primary role and for networking it's important to know access controls like Security groups, ACLs, etc.

Domain 4: Design Cost-Optimized Architectures - 18%

4.1 Identify cost-effective storage solutions 4.2 Identify cost-effective compute and database services 4.3 Design cost-optimized network architectures

(SAA-C02) Exam Guide

In the last domain, you need to know how to build cost-efficient architectures with scalability and resiliency taken into consideration. You'll also need to know how to select the right type of resource to effectively do the task at hand. And at last, it's important to know how to optimize your network design to transfer data the most efficiently from on-premise to the Cloud.

How to prepare for the exam?

In this section, I've bundled up some notes which can be of use when preparing for the AWS Solutions Architect Associates exam. Prior to this Blogpost, I've also released a guide for the AWS Cloud Practitioner exam technical preparation notes. This contains the foundational information which also helps for this exam, so I highly recommend reading the notes from there as well.

Moving on to the preparation, I’ve written some technical notes which highlight important details that are worth remembering. At last, I’ll be sharing my AWS Solutions Architect learning material list which contains a curated collection of high-quality content to help you study efficiently.

The learning material is divided into two parts:

  • Reading material
  • Visual material

For the readers, I'll be sharing my recommended books to read. For the visual learners, I'll provide the videos that will help you prepare for the exam.

Technical Preparation notes

The technical notes are a bundled package of dense information that helps you get insight into what technical services and details are being treated at the exams. I've divided it into the domains that you'll see at the exam.

Domain 1: Design Resilient Architectures

EC2 Storage types

  • Amazon Elastic Block Store (Amazon EBS) provides block-level storage volumes for use with Amazon EC2 instances. Three flavors: Magnetic, General purpose SSD, provisioned IOPS SSD. Snapshots can be created and are saved in S3.
  • Ephemeral storage (legacy) is temporary storage for your EC2 instance. Good to use as a scratch disk, not storing data! Data will be removed after the instance shuts down.

Elastic File System (EFS) It's highly durable storage that can be shared with EC2 instance (NFS protocol). A good use case for former stateful applications that need block storage but aren't scalable yet. This provides a good solution to make your application scalable whilst keeping the data intact.

Amazon Simple Storage Service (S3)

S3 is object storage which is highly durable 99.999999999% with virtually unlimited capacity. It contains different storage classes:

  • S3 standard
  • S3 Intelligent-Tiering
  • S3 Standard-Infrequent Access
  • S3 One Zone-Infrequent Access
  • S3 Glacier
  • S3 Glacier Deep Archive

Design decoupling systems using AWS services

Decoupling components becomes important when you're architecting in the cloud. Loose coupling isolates the layers and components of your application so that each component interacts asynchronously with the others. This is necessary if you want to enable scalability and want your system to become stateless.

Example of an order dispatcher decoupled system using SQS and Autoscaling

Elastic Load Balancer (ELB)

ELB's are a trivial part of high availability and scalability. It comes in 3 flavors:

Domain 2: Design High-Performing Architectures

Amazon RDS

For relational databases, Amazon RDS is the appropriate fit. The perks of RDS is that it can scale vertically (larger instance type + increase storage). Use RDS if you need complex queries or complex transactions.

RDS database engines:

  • Aurora
  • PostgreSQL
  • MySQL
  • MariaDB
  • Oracle
  • MsSQL

RDS backup features:

  • You can have up to 5 read replicas for MySQL and PostgreSQL
  • you can have read replicas in different regions for MySQL only
  • replication is asynchronous only
  • read replicas can be built off multi-az databases
  • you can have read replicas of read replicas but only for MySQL and will further increase latency
  • DB snapshots and automated backups cannot be taken off read replicas
  • synchronous replication is used for multi-az


DynamoDB is a fully managed NoSQL database service that provides fast and predictable performance with scalability. Use DynamoDB if you have applications that need consistent, single-digit millisecond latency at any scale, such as mobile, web, gaming, ad tech, IoT, and many other applications

DynamoDB provisioned throughput:

  • Eventual consistent reads (default)
    • Consistency across all copies of data is usually reached within a second. Repeating a read after a short time should return the updated data (best read performance)
  • Strongly consistent reads
    • A strongly consistent read returns a result that reflects all writes that received a successful response prior to the read.


Amazon ElastiCache is a web service that makes it easy to set up, manage, and scale distributed in-memory cache environments in the cloud. It allows you to improve the performance of applications and databases by offloading read-intensive requests to the in-memory stored cache of Elasticache. This improves the latency and throughput of your workloads.

Elasticache supports two engines: Redis & Memcached, here is a screenshot with the differences between both:

Table containing showing the differences between Redis and Memcached


CloudFront is a global Content Delivery Network (CDN) that's good for serving static content to the end-user through its global edge locations. YOu can deliver videos, images, etc.. with the lowest latency and high transfer speeds.

Some of the key features:

  • Caching content
  • Compatible origins: S3, EC2 + on-prem servers, and ELB.
  • DDOS mitigation (AWS Shield Standard and Advanced)
  • Lambda@edge

The following example shows how you can cache WordPress static content that originates from an S3 bucket. Depending on the request header, in this example /wp-admin, CloudFront is able to send your request to the ELB.

CloudFront caching example with WordPress


Domain 3: Design Secure Applications and Architectures

Shared responsibility model

You should be familiar with the shared responsibility model, the diagram can be found in the security domain of the AWS Cloud Practitioner guide, Domain 2: Security

AWS Identity and Access Management (IAM)

IAM Identities:

  • Users: That's an entity you create in AWS which you can use to login to the AWS console or access APIs through the AWS CLI using Access keys.
  • groups: That's a collection of IAM users.
  • Roles: This is an entity that can be assumed by another task, role, or person. It doesn't need a password or access key. The policy assigned to it can decide who or what services get permission to do the actions which you described. Roles are always better to manage than IAM users.
  • Policies: This is where you set the permission which gets assigned to a role or user, for example:
{ "Version": "2012-10-17", "Statement": { "Effect": "Allow", "Action": [ "s3:List*", "s3:Get*" ], "Resource": [ "arn:aws:s3:eu-west-1:123456789012:my_bucket", "arn:aws:s3:eu-west-1:123456789012:my_bucket/*", ] } }

AWS Key Management Service

AWS KMS Allows you to encrypt data within your own application using keys you create and control. There are three types of keys:

  • AWS Managed
  • Customer Managed
  • Customer Managed, imported key material

Key rotation for AWS managed keys:

  • Rotates automatically every 3 years
  • you cannot manage rotation yourself
  • managed keys cannot be deleted

Key rotation for Customer Managed Keys (CMK):

  • Once a year automatically (disabled by default)
  • on-demand manually
  • Create a new CMK and manually change your applications or aliases to use the new CMK
  • You control the rotation frequency
  • Keys can be deleted

Key rotation for imported key material:

  • No automatic rotation
  • You need to handle the rotation yourself
  • Create new CMK and update your applications to use the new CMK or key Alias


The AWS CloudHSM service is using a dedicated Hardware Security Module (HSM) instances within the AWS cloud to encrypt and protect your data.


This video gives a great walkthrough of the fundamentals of Amazon VPC. I highly recommend you watch it.


Domain 4: Design Cost-Optimized Architectures

You should know how to take cost into consideration when building your architectures in the Cloud.

Important takeaways:

  • Pricing is calculated based on Compute, Storage, and Data transfer.
  • Know the EC2 pricing model for instances including types e.g. Compute-optimized, Memory-optimized, Storage-optimized, etc.
  • You should know when to use reserved instances over on-demand or spot instances.
  • Workloads that don't need constant uptime can be changed to AWS Lambda for example
  • Know which data storage service (EBS, S3, RDS) and class to use.
  • Have a look at the pricing overview whitepaper below to see how prices are being calculated for the most used AWS services.
