AWS DynamoDB vs. RDS: When to Choose One Over the Other
AWS DynamoDB vs. RDS: Which One is Right for Your Application?

Introduction
When building applications in AWS, choosing the right database is critical for performance, scalability, and cost efficiency. AWS offers two powerful database services: DynamoDB and RDS (Relational Database Service). Both have distinct features and cater to specific workloads, but how do you decide which one is the best fit for your use case?
In this blog, we’ll compare DynamoDB and RDS, discuss their advantages and limitations, and explore real-world use cases. We’ll also include Terraform and CloudFormation templates to help you deploy these services seamlessly.
What is AWS DynamoDB?
DynamoDB is a fully managed NoSQL database service designed for key-value and document-based applications. It’s optimized for low-latency, high-throughput workloads.
Key Features of DynamoDB
- Serverless: No need to manage infrastructure.
- Auto-Scaling: Adjusts capacity automatically based on demand.
- Global Tables: Multi-region replication for high availability.
- Durability: Data is stored across multiple Availability Zones.
