AppMod Catalog Blueprints

Application Modernization (AppMod) Catalog Blueprints is a comprehensive library of use case-driven infrastructure solution blueprints built using AWS well-architected best practices. Designed as composable multi-layered building blocks using AWS Cloud Development Kit (CDK) L3 constructs, these blueprints offer use case-driven solutions with multiple implementation pathways and industry-specific implementations to accelerate serverless development and modernization on AWS.

Key Benefits:

• Use case-driven solutions: Purpose-built blueprints for common business scenarios like document processing, web applications, and AI workflows, with industry-specific implementations like insurance claims processing
• Multi-layered approach: Infrastructure Foundation → General Use Cases → Industry Examples, allowing you to start with proven patterns and customize as needed.
• Composable architecture: Mix and match independent components with standardized interfaces
• Enterprise-ready: Built-in security, compliance, and AWS Well-Architected best practices
• Multi-language support: Available in TypeScript, Python, Java, and .NET via JSII

Getting Started

Environment Setup

# Configure AWS credentials and region
aws configure
# OR set AWS profile: export AWS_PROFILE=your-profile-name

# Bootstrap your AWS environment (one-time setup)
npx cdk bootstrap

Quick Deploy (Complete Solutions)

Deploy working examples in minutes for immediate value:

# Clone the repository
git clone https://github.com/cdklabs/cdk-appmod-catalog-blueprints.git

# Deploy complete insurance claims processing solution
cd examples/document-processing/doc-processing-fullstack-webapp
npm install && npm run deploy
# Full AI-powered solution with web interface deployed

# Or deploy basic document processing
cd examples/document-processing/bedrock-document-processing
npm install && npm run deploy

Using Individual Constructs

Add to your existing CDK projects for custom solutions:

# Install the library
npm install @cdklabs/appmod-catalog-blueprints

# Use in your CDK code
import { AgenticDocumentProcessing, WebApp } from '@cdklabs/appmod-catalog-blueprints';

const docProcessor = new AgenticDocumentProcessing(this, 'Processor', {
  agentDefinition: {
    bedrockModel: { useCrossRegionInference: true },
    systemPrompt: myPrompt,
    tools: [myTools]
  }
});

Key Design Principles

AppMod Catalog Blueprints is built on Object-Oriented Programming (OOP) principles, providing a structured approach to infrastructure development through core design concepts:

Composable Architecture

Build complex enterprise systems by combining independent, reusable components with standardized interfaces.

• Independent components with clear interfaces and loose coupling for maximum flexibility
• Mix and match building blocks to create custom solutions across different contexts and use cases
• Scalable composition that maintains consistency while enabling incremental adoption and gradual modernization

Multi-Layered Building Blocks Architecture

Our blueprints use a multi-layered architecture that bridges the gap between business requirements and technical implementation:

| Layer | Implementation Type | Purpose | Key Features | |-------|-------------------|---------|--------------| | Infrastructure Foundation | Abstract base classes | Shared infrastructure components and common services | • Standardized interfaces and contracts• Extensible foundation for custom implementations | | General Use Case Implementation | Concrete implementation classes | Implementations for common patterns across industries | • Configurable parameters for different environments• Abstract method implementations with general-purpose solutions | | Industry-Aligned Implementation | Configured implementation examples | Pre-configured solutions for specific business domains | • Industry-specific validation rules and workflows• Built-in compliance requirements and domain expertise |

Security & Compliance

All components include enterprise-grade security by default:

• CDK Nag Integration: Automated security compliance checking
• AWS Well-Architected: Security, reliability, and performance best practices
• Encryption & IAM: At-rest/in-transit encryption with least-privilege access
• Compliance Reports: Generate reports with npm test -- --testPathPattern="nag.test.ts"
