The most effective features of Amazon S3 are its robust storage capabilities wherein you can combine it with different solutions, using it as a repository for analytics, whether for video analytics or data analytics, allowing for dynamic adjustment of storage automatically without any requisition or long process.

Amazon S3 is easy to use and it is beneficial to use the CLI to make the backups. Since I use the CLI I do not have to do it on a web portal which is a big advantage because everything can be automatized. Automation can be done very well in Amazon S3.

My company uses Amazon S3 by default for every single project. I like that you can use it for storing different file formats. Amazon S3 is also the easiest to use compared to other solutions.

We need the mapping to Windows. That feature is needed in S3. That feature is in the Azure cloud where we can map it like a drive. We can map the cloud storage to the effort driving our Windows PC. But Amazon is not providing that feature for the S3 solution.

The solution needs to improve test recognition.

The tool's speed is comparatively low, especially considering that there are some other services where we can store data, like EBS.

The solution could improve by having a simpler way to have the detail size of a file in the CLI to be read or understood easier. Today, it's a little raw in the way the details are presented. You have to make some scripts and some modifications to be able to see the information properly of the size of a given bucket or the size of a file.
Syed Zakaulla - PeerSpot reviewer
Feb 13, 2023
The pricing for Amazon S3 needs improvement. Another area for improvement is the file size change because it has some limitations that require more time for rendering, especially if you're not merely uploading a file, but reviewing that file, too.

One thing would be automatic replication between buckets, some feature like that.

I would also like S3 to have the ability to do dynamic websites without the need to do reconfigurations outside of S3. You should be able to switch on dynamic websites in S3, and then it works. I shouldn't need to go elsewhere within Amazon Web Services to get a dynamic website to work.
