"Effortless, Scalable Data Storage with Buckets and Partitions"
5/5
What do you like best about Amazon Simple Storage Service (S3)?

I use Amazon Simple Storage services professionally as part of our data engineering and ETL workflow. We store both raw and processed data in S3, and then use it with AWS Glue, EMR, and Athena. Our ETL jobs generate Parquet and CSV outputs, which are stored in S3 for downstream consumption and for querying in Athena. Overall, the platform has been especially useful because of its durability, scalability, and seamless integration. Review collected by and hosted on G2.com.

"Cost-Effective, Seamless Salesforce Attachment with Amazon S3"
4.5/5
What do you like best about Amazon Simple Storage Service (S3)?

What I like most about Amazon S3 is how cost-effective and easy it is to use, especially when dealing with large volumes of files. We use it to store all the attachments coming from Salesforce, and it has helped us significantly reduce our storage costs compared to keeping everything within Salesforce.

We had earlier been using S-Drive, but moving to S3 turned out to be a better decision from a cost and flexibility standpoint. The integration with Salesforce has been smooth, and the whole process feels seamless. Uploading files from Salesforce to S3 is straightforward, and users can easily access and download them whenever needed. Review collected by and hosted on G2.com.

"Versatile Data Lake Storage for Logs, Backups, ETL, and Archival"
4.5/5
What do you like best about Amazon Simple Storage Service (S3)?

I use it for data lake storage, including storing logs, backups, and reports. It also works well for hosting files and static assets, supporting ETL pipeline input/output storage, and handling archival needs and disaster recovery. Review collected by and hosted on G2.com.

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

Managing permissions, lifecycle policies, and large bucket structures can get complicated at scale. As bucket policies become more complex, coordinating large-scale permissions across multiple teams can be difficult without clear governance standards in place.

"Solid storage but a bit of a maze to set up"
3.5/5
What do you like best about Amazon Simple Storage Service (S3)?

The best part is definitely the reliability. I use it for storing all my team's project files and honestly, it never goes down. Once it's running, you just forget about it and it works. Also, the speed for uploading and downloading big files is much better than other stuff we tried before. It's great that it scales automatically so I don't have to worry about running out of space. Review collected by and hosted on G2.com.

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

The interface is just... too much. If you're not a pro, finding specific settings in the console feels like a puzzle. Also the pricing is super confusing. It's hard to predict how much we're gonna pay at the end of the month because of all those extra fees for data transfer and requests. I wish it was more straightforward for a regular user who just wants to store stuff. Review collected by and hosted on G2.com.

"Reliable, scalable, and highly integrated cloud storage"
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.

"Reliable and scalable cloud storage solution for all use cases"
5/5
What do you like best about Amazon Simple Storage Service (S3)?

Amazon S3 provides incredibly reliable and highly scalable object storage, making it perfect for everything from backup storage to hosting static websites and data lakes. The integration with other AWS services is seamless, and the pay-as-you-go pricing model makes it very cost-effective for both small and enterprise use cases.

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

The pricing model, while flexible, can be confusing—especially when dealing with multiple storage classes, data retrieval fees, and transfer costs. Also, managing permissions with bucket policies and IAM roles can get complex and error-prone without clear documentation or experience. A better built-in UI for file management in the AWS Console would also improve user experience. Review collected by and hosted on G2.com.
