Featured Reviews

Roberto Costa - PeerSpot reviewer
Have used multiple features effectively and find the pricing reasonable
What I appreciate most about Amazon S3 is the tiering of the objects; with the tiering, we can determine if an object won't be accessed frequently and send it to cold storage or a Glacier storage unit, which greatly lowers AWS costs. The inventory feature, called S3 Inventory, is a cool feature as well. The object access point is another notable feature. Amazon S3 has many useful features; I can simply host my website, which has to be a static web page, but even so, it's beneficial to put my code inside of Amazon S3 as a static website that people worldwide can access. I have worked with many petabytes of data stored in Amazon S3, and I have never had any performance issues, stability issues, or anything similar.

PriyankShrivastava - PeerSpot reviewer
A workhorse that enables high availability but support has room for improvement
There is always room for improvement. When a product is marketed, many claims are made, but in reality, it does not always perform as expected. The usability and real-time capabilities could be enhanced. The product can be difficult to use compared to how it is marketed. Technical support also lacks a timely response.
