AWS Microservice Architecture Diagramming Template

The AWS Microservice Architecture template shows you how to set up a super-flexible microservices application using key AWS serverless services. Imagine your app as many small, independent teams instead of one giant one. 

• API Gateway acts as the front door, handling all incoming requests. 

• Lambda functions are your efficient workers, running small pieces of code without you worrying about servers. 

• DynamoDB is your super-fast database for storing information. 

• AWS EventBridge is the communication hub, making sure all your microservices can talk to each other seamlessly through events. 

This design helps you build apps that are easy to scale and adapt. 
 

When and How to Use This Template?

The AWS Microservice Architecture template is a valuable asset for various scenarios, from initial planning to ongoing development: 

When to Use It: 

• Starting a New Serverless Project: Get a clear, pre-defined architecture when beginning a new microservices application on AWS. 

• Visualizing Complex Architectures: Easily understand and explain how API Gateway, Lambda, DynamoDB, and EventBridge interact in an event-driven microservices setup. 

• Transitioning from Monoliths: Use it as a blueprint for breaking down existing monolithic applications into smaller, manageable microservices. 

• Standardizing Deployments: Create a repeatable, consistent architecture for deploying new microservices or entire applications. 

• Team Collaboration & Onboarding: Facilitate discussions, align your team, and quickly onboard new members to your microservices design principles. 

• Stakeholder Communication: Present a clear, visual overview of your application's architecture to non-technical stakeholders. 

How to Use It in Cloudairy?

1. Find the Template: 

• Log in to your Cloudairy account. 
• Navigate to the Templates section. 
• Search for "AWS Microservice Architecture Diagram" or choose "AWS Microservices" from categories. 
• Click to open the template preview. 

2. Explore and Understand: 

• Examine the pre-built diagram to understand the connections between API Gateway, Lambda, DynamoDB, and EventBridge. 
• Trace the data flow for typical operations (e.g., how a user request flows through the system). 

3. Customize for Your Needs: 

• Select "Use Template" to open it for modification. 
• Define your APIs: Adjust API Gateway endpoints and methods. 
• Develop Functions: Detail the specific logic for your AWS Lambda functions. 
• Connect Databases: Specify your DynamoDB table structures or integrate other data stores. 
• Enable Event-driven Workflow: Design custom events and rules within EventBridge for your microservices' interactions. 
• Add or remove components to accurately reflect your unique application requirements. 

4. Collaborate and Plan: 

• Use the visual diagram during team planning sessions to ensure everyone is aligned on the architecture. 
• Share the customizable template with your team for real-time collaboration and feedback. 

5. Prepare for Deployment & Monitoring: 

• The template serves as a robust blueprint that can guide your actual AWS deployment (e.g., using Infrastructure as Code tools like CDK). 
• Reference the integrated CloudWatch Monitoring components to plan your observability strategy. 
   

The main components inside the Template

Here are the core components that make up your AWS Microservice Architecture: 

• AWS API Gateway: Your app's main entrance for web requests. 

• Lambda Functions: Serverless code that runs your app's logic. 

• DynamoDB Tables: Fast storage for your app's data. 

• Example Microservices: Like a "Basket Microservice" for shopping carts, a "Product Microservice" for inventory, and an "Ordering Microservice" for purchases, illustrating common microservice patterns. 

• Checkout Event: An example of how actions (like a completed order) can trigger other services via events. 

• AWS EventBridge: The central system for sending messages between your services. 

• SQS Queue: A queue for managing messages that need to be processed asynchronously. 

• CDK CloudFormation: Tools that help automate how your entire architecture is built in AWS. 

• Users: Represents end-user interactions with your application. 

• Security Groups: Rules that control network access for your services. 

• IAM Roles: Permissions that define what each service can do in AWS. 

• CloudWatch Monitoring: For keeping an eye on your system's health and performance. 

• Load Balancer: For distributing incoming traffic evenly across your services (if needed for specific microservice implementations).
   

Summary 

Easily map out your microservices with this ready-to-use template. See how each service like API Gateway, Lambda, and DynamoDB connects, works together, and scales — all in one clear, visual layout. AWS Microservice Architecture template helps you create applications that are resilient, communicate smoothly, and are cost-effective to run.
