Amazon Aurora Tutorial
1. Introduction
Amazon Aurora is a MySQL and PostgreSQL-compatible relational database built for the cloud, offering high performance, availability, and security. It is part of Amazon Web Services (AWS) and is designed to provide the performance of high-end commercial databases at a fraction of the cost.
Its relevance lies in its ability to automatically scale, its fault-tolerant architecture, and its seamless integration with other AWS services, making it a popular choice for modern application development.
2. Amazon Aurora Services or Components
- Aurora MySQL: A MySQL-compatible database engine that combines the performance and availability of high-end commercial databases with the simplicity and cost-effectiveness of open-source databases.
- Aurora PostgreSQL: A PostgreSQL-compatible database engine designed to provide the performance and availability of commercial databases at open-source costs.
- Global Database: Enables a single Aurora database to span multiple AWS regions, providing low-latency reads and disaster recovery.
- Replication: Aurora supports both physical and logical replication for enhanced data availability and durability.
- Backup and Restore: Automated backups and point-in-time recovery are built-in features that enhance data protection.
3. Detailed Step-by-step Instructions
To set up an Amazon Aurora database, follow these steps:
1. Login to the AWS Management Console.
