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.
Manimaran Tannimalai - PeerSpot reviewer
User interface consistency facilitates seamless project planning and design for specialized tasks
While Google has made efforts to address SAP loads, the company lacks a product specialist focus. They cover a broad range of products, which might affect their ability to compete well in certain niches. Google's strength lies in their adapted approach to specific tasks, as seen with SAP loads. Generally, their focus is widespread.
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.
