Elements of AWS Architecture Diagram

Utilizing architecture diagrams is an excellent method for effectively conveying your design, deployment, and network structure. When it comes to AWS architecture diagrams, there exists an official assortment of AWS service icons, resource icons, supplementary assets, and guidelines. These resources serve as valuable tools in constructing AWS architecture diagrams that are customer-centric and maintain consistency.

Key elements of AWS architecture diagram:

  • Icons: In AWS architecture diagramming, icons play a vital role in visually representing various AWS services, resources, and components. These icons are specifically designed to depict the diverse range of services offered by AWS, making it easier to understand and communicate complex cloud architecture. By incorporating AWS icons into your diagrams, you can effectively illustrate the presence and functionality of different AWS services within your cloud infrastructureaws resouce and service icons
  • Groups: When creating an AWS architecture diagram, organizing related components and resources into groups is essential for clarity and structure. Groups allow you to logically categorize and visually group together components that belong to the same function, system, or layer within your cloud architecture (Ex. Region -> VPC -> Subnet hierarchy). This helps in presenting a clear and concise representation of your cloud infrastructure, making it easier to comprehend and analyzeaws groups
  • Lines play a crucial role in AWS architecture diagrams as they represent the connections and relationships between various components and resources. These lines depict the flow of data, communication, and dependencies between different elements in your cloud architecture.

Types of AWS Architecture Diagrams

The term "AWS architecture diagram" encompasses various diagram types that focus on visualizing connections and relationships within the AWS cloud. In most scenarios we can group AWS diagrams in two main groups:

  • AWS network diagrams, that provide a comprehensive overview of the network infrastructure within AWS. This includes diagrams such as the AWS VPC diagram, which illustrates the Virtual Private Cloud and its components and related resources such as subnets, gateways, routers, EC2 instances, load balancers etc. Additionally, the AWS serverless architecture diagram focuses specifically on showcasing the design and flow of serverless applications, highlighting AWS services like AWS Lambda, API Gateway, and event triggers. Additionally, it is worth mentioning that the AWS VPC diagram can be combined with an AWS serverless architecture diagram. This combination allows for a more comprehensive representation of the overall system architecture. By integrating both diagrams, you can visualize the networking infrastructure provided by the VPC along with the serverless components and their interactions within the architecture
  • Diagrams that are not primarily network related. These diagrams serve specific purposes such as security architecture diagrams, which aid in visualizing the different security measures employed within an AWS environment. They showcase elements such as IAM roles, security groups, encryption mechanisms, and monitoring solutions, offering a comprehensive overview of the security posture. Another example within this group is AWS Organizations setup, which involves organizing resources using organizational units and AWS accounts. Additionally, there are CI/CD related diagrams that illustrate the relationships between AWS deployment services such as AWS CodeBuild and CodePipeline, as well as AWS native code versioning services like AWS CodeCommit, or external ones like GitHub, GitLab, and others. These diagrams provide a visual representation of the CI/CD process, showcasing the integration of various tools and services involved in building, testing, and deploying applications on AWSAWS ci/cd pipeline diagram

Serverless Web Application Architecture

AWS serverless web application diagram

This diagram presents a high-level example of an AWS serverless web application architecture, showcasing the main steps involved in utilizing various AWS serverless services:

  1. Request is sent from browser for domain name
  2. DNS Resolver retrieves IP address from Route 53 (keep in mind that there are other DNS related queries before this) based on DNS record for domain
  3. Route 53 has A alias record pointing to CloudFront distribution
  4. Browser sends request towards CloudFront distribution to retrieve static content files. In order to serve content over HTTPS there is generated TLS certificate for in Certificate Manager and specified in CloudFront distribution configuration
  5. CloudFront requests static content files from S3 bucket and static content files are sent back to browser and processed there
  6. Browser sends new requests towards API Gateway to request necessary data (of course all the 1. and 2. steps are executed before in order to get IP address of API Gateway REST API)
  7. API Gateway sends request to Lambda for processing
  8. Lambda processes request and requests data from DynamoDB and then response is sent back all the way to browser
