AWS Console and DynamoDB setup

Introduction

We use the AWS Console to create and manage DynamoDB tables easily. DynamoDB stores data in a fast and scalable way without managing servers.

You want to store user data for a web or mobile app.

You need a database that can handle lots of requests quickly.

You want a database that automatically scales with your app.

You prefer a simple way to create and manage databases without coding.

You want to try AWS services using a visual interface before coding.

Syntax

DynamoDB

1. Sign in to AWS Console
2. Search for DynamoDB service
3. Click 'Create table'
4. Enter Table name and Primary key
5. Choose settings (like capacity mode)
6. Click 'Create'

The Primary key uniquely identifies each item in the table.

Capacity mode can be 'On-demand' (pay per request) or 'Provisioned' (set capacity).

Examples

This creates a table named 'Users' where each user is identified by a unique UserID.

DynamoDB

Table name: Users
Primary key: UserID (String)

This creates a table named 'Products' where each product is identified by a unique number.

DynamoDB

Table name: Products
Primary key: ProductID (Number)

Choose this to pay only for the requests you make, good for unpredictable traffic.

DynamoDB

Capacity mode: On-demand

Choose this to set fixed capacity, good for steady traffic and cost control.

DynamoDB

Capacity mode: Provisioned
Read capacity units: 5
Write capacity units: 5

Sample Program

This step-by-step creates a DynamoDB table named 'Books' with ISBN as the unique key and uses on-demand capacity for flexible usage.

DynamoDB

1. Open AWS Console and sign in.
2. Search for 'DynamoDB' and select it.
3. Click 'Create table'.
4. Enter Table name: 'Books'.
5. Set Primary key: 'ISBN' (String).
6. Choose Capacity mode: On-demand.
7. Click 'Create'.

Important Notes

Always choose a meaningful Primary key to avoid duplicate data.

On-demand mode is easier for beginners as it requires no capacity planning.

Use AWS Console for quick setup and testing before automating with code.

Summary

AWS Console lets you create DynamoDB tables visually without coding.

Primary key is required to uniquely identify each item in the table.

Capacity mode affects cost and performance; choose based on your app needs.
