• Why Use It? Up to 5x faster than MySQL, managed backups, auto-scaling, and global replication.

2. Amazon Redshift

• Type: Data Warehouse (Analytics DB)

• Use Case: Running complex analytical queries on huge datasets (petabyte-scale).

• Why Use It? Fast, scalable data analytics, integrates with BI tools like Tableau, Power BI, etc.

3. Amazon ElastiCache

• Type: In-Memory Store
