Managing data on the AWS platform involves leveraging a wide range of services designed for storage, databases, analytics, governance, security, and migration. AWS provides scalable, secure, and highly available solutions to handle structured, semi-structured, and unstructured data across various use cases—from simple file storage to complex data lakes and real-time analytics.
Here’s a comprehensive overview of managing data on AWS:
1. Storage Services

- Policy-based, automated backups with lifecycle management.
Cross-Region Replication (S3, DynamoDB, RDS)
- For disaster recovery and low-latency global access.
Point-in-Time Recovery (RDS, DynamoDB)
- Restore to any second (within retention window).
8. Monitoring & Optimization
Amazon CloudWatch
- Monitor metrics, logs, and set alarms for data services.
AWS Trusted Advisor & Cost Explorer
- Optimize costs and performance (e.g., S3 lifecycle policies, idle RDS instances).
AWS Compute Optimizer
- Recommends optimal EBS volume types and sizes.
Best Practices for Managing Data on AWS
- Classify and Govern Data: Use tags, Lake Formation, and Macie to understand and secure data.
- Choose the Right Storage Class: Optimize cost with S3 Intelligent-Tiering or Glacier for archival.
- Automate Backups & DR: Use AWS Backup and enable versioning/cross-region replication.
- Encrypt Data at Rest and in Transit: Use KMS, SSL/TLS, and S3 bucket policies.
- Monitor and Audit Access: Use CloudTrail, Config, and IAM policies with least privilege.
- Leverage Serverless Where Possible: Reduce operational overhead (e.g., DynamoDB, Glue, Athena).
- Optimize Query Performance: Use columnar formats (Parquet/ORC), partition data in S3, use Redshift sort/dist keys.
- Plan for Scalability & Cost: Right-size instances, use auto-scaling, and monitor with Cost Explorer.
