Day 42: Building and Managing NoSQL Databases with AWS DynamoDB

Weclome to Day 42. Today we will learn how to build and manage NoSQL Databases with AWS DynamoDB.

What is DynamoDB?

Amazon DynamoDB is a fully managed NoSQL database service provided by AWS (Amazon Web Services). It is designed to store and retrieve large amounts of data very fast, with high availability and automatic scaling, without you needing to manage servers.

🔹 Key Characteristics of DynamoDB

1️⃣ NoSQL Database

• Stores data as items (similar to rows)

• Uses key–value and document data models

• Schema is flexible (attributes can vary per item)

You don’t manage:

• Servers

• Operating systems

• Patching

• Backups

• Scaling

AWS handles all of this automatically.

3️⃣ Extremely Fast Performance

• Single-digit millisecond latency

• Designed for high-traffic applications

• Handles millions of requests per second

---

4️⃣ Highly Scalable

• Automatically scales read and write capacity

• Supports on-demand and provisioned capacity modes

---

5️⃣ High Availability & Durability

• Data is replicated across multiple Availability Zones

• Built-in fault tolerance

• Designed for 99.999% availability
