Side-by-Side Comparison Matrix

Metric	Node.js / MongoDB / RAG	Python / Postgres / Fine-Tuning
Market Share	Leader (broadest web developer ecosystem)	Second (strongest enterprise sales presence)
Container Services	ECS, EKS, AWS Fargate (Developer favorite)	AKS, Azure Container Apps
Database Options	DynamoDB, RDS, Aurora (highly optimized)	Cosmos DB, Azure SQL (highly integrated)
Enterprise Integration	Moderate (mostly cloud-native)	Excellent (Active Directory, Office 365 integration)
Pricing Structures	Complex (standard compute and database costs)	Enterprise-friendly (volume discounts, hybrid licensing)
