5/5

What do you like best about Amazon Simple Storage Service (S3)?

Amazon S3 offers reliable, scalable, and highly durable object storage, with smooth integration across the AWS ecosystem. I find it easy to use, and the setup is straightforward for storing, retrieving, and managing large volumes of data. Its flexibility, the range of storage classes, and strong security controls make it well suited for both frequent access and archival needs. Integration with services such as Lambda, CloudWatch, and EC2 also supports automated workflows and more efficient data management. Review collected by and hosted on G2.com.

What do you dislike about Amazon Simple Storage Service (S3)?

While S3 is extremely reliable, managing complex permissions and policies can be challenging, especially for beginners. Costs can also add up quickly if you rely heavily on versioning or perform frequent data transfers. In addition, working with very large buckets containing millions of objects can feel cumbersome without solid organization and well-defined lifecycle policies. Review collected by and hosted on G2.com.

What problems is Amazon Simple Storage Service (S3) solving and how is that benefiting you?

S3 addresses the challenge of scalable, durable data storage. It enables our team to store large volumes of data reliably while maintaining strong availability and security.
