Data Engineer at a tech vendor with 10,001+ employees
Has reduced storage costs and improved data management through automated lifecycle and seamless service integration
The best features that Amazon S3 offers are high durability and availability with virtually unlimited storage, lifecycle management for automated tiering and cost control, versioning to retain and recover data changes, and integration with services such as Glue, Athena, EMR, Lambda, along with strong security via IAM roles, bucket policies, and encryption. These features help by ensuring data is always available, securely stored, and easily accessible for pipelines. Lifecycle policies reduce manual cleanup, versioning safeguards against accidental deletions, and integrations allow us to directly run analytics or trigger workflows without moving data around. Amazon S3 event notifications help automate tasks such as triggering ETL jobs or Lambda functions on new data arrivals, and features such as cross-region replication ensure data redundancy and compliance, while fine-grained access control makes it easy to manage permissions across teams securely. My organization has seen improvements in data accessibility, reduced infrastructure costs, and simplified data management through Amazon S3. We now have a unified scalable storage layer that supports analytics, backups, and migrations seamlessly, leading to faster workflows and better decision-making.
