🚀 ONDEMANDENV

Taming Distributed System Complexity Through Application-Centric Infrastructure

🌟 The Revolution

ONDEMANDENV transforms distributed system complexity into Application-Centric Infrastructure - enabling teams to manage their complete technology stack as a single, cohesive unit through Unified Cloud Stacks.

⚡ The Magic: Branch = Environment

# Create complete isolated environment for any feature
git commit -m "feature: new payment API

odmd: create@dev"

# Platform automatically provisions:
# ✅ AWS resources (S3, RDS, IAM roles)
# ✅ Kubernetes workloads and services  
# ✅ Cross-account network connectivity
# ✅ Security policies and monitoring
# ✅ Complete application stack

🔄 Traditional vs ONDEMANDENV

🏗️ Architecture Ecosystem

🎯 Three-Layer Innovation

📋 ContractsLib - Architecture as Code

Central “Congress” where teams negotiate service boundaries through code contracts

🏛️ Platform Services - Shared Infrastructure

Enterprise-grade services (Networking, EKS, Databases) consumed without operational burden

🚀 Applications - Unified Cloud Stacks

Real apps demonstrating AWS + Kubernetes unified in single codebases

🚀 Repository Ecosystem

🏛️ Foundation

• contracts-base - Abstract interfaces & validation
• contracts-sandbox - Reference implementation & coffee shop demo

🌐 Platform Services

• networking - IPAM, Transit Gateway, cross-account VPCs
• odmd-eks - Production EKS with IRSA security
• springcdk-rds - Database platform services

📱 Application Examples

• spring-boot-swagger-3-example - Unified Cloud Stacks demo
• coffee-shop--foundation - Shared microservice infrastructure
• coffee-shop--order-manager - Business service example

📚 Documentation

• ondemandenv.github.io - Comprehensive platform docs
• user-pool - Console authentication service

🎯 Core Innovation: Unified Cloud Stacks

Before: Fragmented Nightmare 😞

# infrastructure.yaml (CloudFormation)
Resources:
  MyBucket: { Type: AWS::S3::Bucket }

# app.yaml (Kubernetes) 
apiVersion: apps/v1
kind: Deployment
# ... manual secrets management ...

After: Unified Excellence 🚀

// Single CDK stack = Complete application
export class MyAppStack extends cdk.Stack {
  constructor() {
    // AWS Resources
    const bucket = new Bucket(this, 'AppBucket');
    const podRole = new Role(this, 'PodRole', {/* IRSA */});
    
    // Kubernetes Resources (cdk8s)
    const chart = new cdk8s.Chart(app, 'AppChart');
    new Deployment(chart, 'App', {
      containers: [{ 
        image: myImage,
        envVariables: { BUCKET_ARN: {value: bucket.bucketArn} }
      }],
      serviceAccount: { 
        annotations: {'eks.amazonaws.com/role-arn': podRole.roleArn} 
      }
    });
    
    // Platform deploys automatically
    new EksManifest(this, 'deploy', { manifest: chart });
  }
}
