Amazon Aurora Global Database

Introduction

Amazon Aurora Global Database is a powerful database solution that helps businesses run their applications worldwide. This guide will explain how to get started with Aurora in simple terms.

What is Amazon Aurora?

Amazon Aurora is a cloud database that's fully managed by AWS. It's compatible with MySQL and PostgreSQL but works up to five times faster than standard MySQL and three times faster than standard PostgreSQL. You can learn more about Aurora basics here: Amazon Aurora Overview

Understanding Aurora Global Database

Think of Aurora Global Database as having copies of your database in different parts of the world. Your main database (called the primary region) handles all write operations, while other regions (called secondary regions) can handle read operations. This setup helps in two main ways:

1. It makes your application faster for users around the world

2. It protects your data if something goes wrong in one region

Key Benefits

When you use Aurora Global Database, you get:

• Fast local reads with less than one second delay worldwide

• Protection against regional failures

• The ability to move your database to a different region in under a minute if needed

• Support for large databases up to hundreds of terabytes

Getting Started

Step 1: Set Up Your Primary Database

First, create your main Aurora database cluster in your chosen primary region. You can do this through the AWS Management Console by visiting: Create Aurora Database

Step 2: Add Secondary Regions

After your primary database is running:

1. Open the Amazon RDS console

2. Select your database cluster

3. Choose "Add AWS Region" from the Actions menu

4. Pick the regions where you want copies of your database

Step 3: Connect Your Application

You'll get different endpoints for writing and reading:

• Use the primary endpoint for all write operations

• Use the reader endpoint in each region for read operations

Best Practices

To get the most out of Aurora Global Database:

• Place secondary regions close to where your users are located

• Monitor replication lag using Amazon CloudWatch

• Test failover procedures regularly

• Use appropriate instance sizes in each region based on your workload

Costs and Planning

Remember that you pay for:

• Database instances in each region

• Storage in each region

• Data transfer between regions

You can estimate costs using the AWS Pricing Calculator
