Databases in AWS – RDS, DynamoDB, Aurora
1.Databases in AWS – RDS, DynamoDB, Aurora
Ans:
AWS offers a range of database services to meet different application needs. RDS (Relational Database Service) is a managed relational database that supports MySQL, PostgreSQL, SQL Server, Oracle, and MariaDB. RDS handles routine database tasks like backups, patching, scaling, and replication, allowing developers to focus on application development rather than database management. It is ideal for applications that require structured relational data.
DynamoDB is a fully managed NoSQL database designed for high performance and scalability. It stores key-value and document data, providing single-digit millisecond response times and seamless scaling without manual intervention. DynamoDB is perfect for applications requiring fast read/write performance, such as gaming, IoT, and mobile apps.
Aurora is a MySQL- and PostgreSQL-compatible relational database built for enterprise workloads. It combines high performance and availability with automatic replication across multiple availability zones. Aurora offers up to five times the performance of standard MySQL and features like automated backups, fault tolerance, and read replicas, making it suitable for large-scale, mission-critical applications.
Together, these AWS databases provide flexibility, scalability, and reliability, enabling developers to choose the right solution—relational or NoSQL—based on application requirements, performance needs, and budget, while reducing administrative overhead.
