Learn what your peers think about Amazon S3. Get advice and tips from experienced pros sharing their opinions. Updated: May 2026.
893,915 professionals have used our research since 2012.
What do I think about the scalability of the solution?
Around 2,000 to 3,000 users use Amazon S3 in our organization.
How was the initial setup?
The solution's initial setup is easy.
What's my experience with pricing, setup cost, and licensing?
While storing data in Amazon S3 is relatively inexpensive, there are costs associated with retrieving or transferring data across continents. Connecting Amazon S3 with real-time applications can increase data retrieval costs.
What other advice do I have?
Amazon S3 is deployed on-cloud in our organization. Our company decided to use Amazon S3 because of its global availability. AWS has multiple data centers around the world.
If you're using the public cloud, using Amazon S3 combined with Amazon S3 Glacier is correct. The data will be stored in Amazon S3 storage, and the cost will increase. Instead of keeping the data in Amazon S3, putting the archive file in Amazon S3 Glacier is better.
Overall, I rate Amazon S3 a nine out of ten.
Disclosure: My company does not have a business relationship with this vendor other than being a customer.
Solutions Architect at Infinite Computer Solutions
An affordable and highly stable product that can be used to store large amounts of data
Pros and Cons
- "The most valuable feature of the product is storage classes."
- "The UI should be more user-friendly."
What is our primary use case?
We use the solution to store BLOB data, analytical data, and large files.
How has it helped my organization?
We use S3 for archiving. We store data for the long term because it is very cheap.
What is most valuable?
The most valuable feature of the product is storage classes. Once we store data in S3, it will be stored in different storage classes as per our needs.
What needs improvement?
The UI should be more user-friendly. I rate the UI a five out of ten. The solution must improve its UI.
For how long have I used the solution?
I have been using the solution for four years.
What do I think about the stability of the solution?
I rate the product’s stability a ten out of ten.
What do I think about the scalability of the solution?
Since the solution is used for data storage, it is not scalable. Its availability is very good. I rate the availability a ten out of ten.
How was the initial setup?
It is very easy to create a bucket in S3. The option to create buckets is available to the users right when they open the S3 console. We can just create a bucket and start using it.
What was our ROI?
We definitely see an ROI on the solution. We can store terabytes and zettabytes of data in S3. We pay very less for it.
What's my experience with pricing, setup cost, and licensing?
The product has one of the best pricing in the market. It is very cost-efficient. The cost depends on the data we access. If we access a particular data regularly, we must pay for it. If we know that we will need the data after three to five years, we can store it in the archives, which will cost us less.
What other advice do I have?
The product has no specific version. We can create buckets and use them. It is a data storage service like Google Drive. I have not used all the features of the product yet. Overall, I rate the solution a nine out of ten.

senior site reliability engineer at a tech vendor with 5,001-10,000 employees
Offers a single-pane-of-glass view and dashboard but fails to offer reports on a real-time basis
Pros and Cons
- "The tool offers great scalability to its users."
- "Everything around visibility, dashboards, and all of the statistics through which the tool provides information 24 hours a day means that it is not done on a real-time basis."
What is our primary use case?
I use the solution in my company mostly to store files. It is a file storage service.
What is most valuable?
I use many features in the tool, including data life cycle, automatic cleanup, and life cycle policies. I also use the tool's single-pane-of-glass view and dashboard. I don't know specifically what the important features are in the tool. The durability and availability features of Amazon S3 are amazing.
What needs improvement?
Everything around visibility, dashboards, and all of the statistics through which the tool provides information 24 hours a day means that it is not done on a real-time basis. It's sometimes needed for users to see some real-time information immediately and not have to wait for 24t hours till a report is generated. For me, getting reports on a real-time basis is critical, and it is an area that is missing in Amazon S3.
For the cleanup policy, when I opened a couple of tickets with the tool's support team, I did not get any clear information on how to deal with the restoration part. When my company approached the tool's technical support with some questions about how to organize data, view it, and how it is distributed across the buckets, we did not receive any clear answers. The tool's support team needs to improve.
For how long have I used the solution?
I have been using Amazon S3 for ten years. I am an end user of the solution.
What do I think about the stability of the solution?
It is a very good and stable solution. Stability-wise, I rate the solution a ten out of ten.
What do I think about the scalability of the solution?
The tool offers great scalability to its users. Scalability-wise, I rate the solution a ten out of ten.
At least half of my organization uses the tool. Most of our company's applications deploy, provide, or utilize the services offered by Amazon S3.
The tool is used on a daily basis.
How are customer service and support?
For the service provided by the solution's technical support, I rate the technical support a six to seven out of ten.
How would you rate customer service and support?
Neutral
Which solution did I use previously and why did I switch?
With Amazon, you don't have any other equivalent services, so Amazon S3 is a standard tool to use. In other environments, very different services, very similar to Amazon S3, are present on GCP and Azure. On other platforms, we use the services provided by other clouds.
How was the initial setup?
The product's initial setup phase is very easy.
The solution is deployed on the cloud. The tool can be deployed on an on-premises model.
The solution can be deployed in a few seconds.
What was our ROI?
Speaking about whether I have seen an ROI from using the tool, I would say that I know that it contains life cycle policies.
What's my experience with pricing, setup cost, and licensing?
The tool's price is a little bit high, but it is reasonable.
What other advice do I have?
The product is very deeply integrated with some of the tools that I use in my company. Amazon S3 is a part of the platform applications that we create and provide to customers.
I recommend the tool to others.
I rate the tool a seven to eight out of ten.

Useful for storage of images and documents
Pros and Cons
- "The most valuable feature of the solution stems from the fact that I mostly used the tool's free tier version, so I like the fact that its cost is very low."
- "I didn't find the user interface very friendly."
What is our primary use case?
I use the solution for the storage of images and documents.
What is most valuable?
The most valuable feature of the solution stems from the fact that I mostly used the tool's free tier version, so I like the fact that its cost is very low.
What needs improvement?
Recently, I was trying to clean up the data because I have a lot of old, unused objects and images. I am trying to identify the files with the highest sizes and determine if I need to keep them or delete them. I didn't find the user interface very friendly. Beyond 399 or 999 objects, the tool's user interface was not allowing me to use the sort option. I had to use various keywords to search phrases and shortlist them so that I got less than 399 objects and could use the sort option. The aforementioned area can be considered for improvement.
For how long have I used the solution?
I have been using Amazon S3 for around three years. I think two years back, I was in a different organization, which was an AWS partner. I am a customer of the tool.
What do I think about the stability of the solution?
It is a stable solution.
How are customer service and support?
The solution's technical support is satisfactory. I rate the technical support a nine out of ten.
How would you rate customer service and support?
Positive
Which solution did I use previously and why did I switch?
In my previous job, I used Sagemaker, but I don't use it currently. I have also used Amazon EC2 and CloudWatch for billing alerts or something that I might have set them up in the company.
How was the initial setup?
The product's deployment phase is quite comfortable with no issues. The tool's maintenance part is fairly easy.
What's my experience with pricing, setup cost, and licensing?
I don't use it that frequently, so I think it's too early to comment on the tool's pricing structure. Six months later, I may have more data related to the tool.
I can't comment on the pricing part of the product since I don't deal with a high workload for now.
I use the tool's free tier. I believe that there is a need to make annual payments towards the licensing charges associated with the product.
What other advice do I have?
Speaking of the process for retrieving data with the help of the tool, I would say that it is used to just display images on a website. When the page is opened, it gets linked to images and I display it on the website using Amazon S3.
I did not face any performance issues with Amazon S3.
I rate the tool a nine out of ten.
