Serverless Architecture

Create serverless architecture diagrams showing functions, triggers, and managed services for AWS Lambda, Azure Functions, and Cloud Functions.

Serverless architecture diagrams document function-based applications, their triggers, and the managed services they integrate with. NeoArc Studio includes icons for all major serverless platforms.

Serverless Components

Serverless architecture diagrams typically show:

Creating Serverless Diagrams

Common Serverless Patterns

API Backend
API Gateway + Lambda + DynamoDB
Event Processing
EventBridge + Lambda + downstream services
File Processing
S3 trigger + Lambda + output storage
Scheduled Jobs
CloudWatch Events + Lambda
Workflow
Step Functions orchestrating multiple functions
Fan-out
SNS + multiple Lambda subscribers

Visual Conventions

Synchronous callsSolid arrows
Asynchronous eventsDashed arrows
Data labelsEvent names on connections

Best Practices

Show All Triggers
Document what invokes each function.
Document Data Flow
What data moves between components.
Include Error Handling
Dead letter queues, retry policies.
Group by Domain
One diagram per bounded context.
