Reliable, responsive support, and scalable
Pros and Cons
- "Amazon S3 is a stable solution."
- "Amazon S3 could improve the load balancers. They are very basic compared to other solutions in the industry, such as F5. It has to be able to be analyzed up to a certain level."
What is our primary use case?
We have multiple use cases for Amazon S3. We use Amazon S3 for storing static data and as a static site load balancer.
What needs improvement?
Amazon S3 could improve the load balancers. They are very basic compared to other solutions in the industry, such as F5. It has to be able to be analyzed up to a certain level.
The basic features need some improvement, users should not have to use any third-party solutions, Amazon S3 should provide those particular features. The feature at present does not suffice most of the requirements of an enterprise-class organization.
The security could improve in Amazon S3. I am not seeing any value in the solution in security.

It's a reliable solution for application logs and other read-only data
Pros and Cons
- "You don't have to specify your clone, availability clone, or your locations. Everything's over there. They have a receipt for the instance where we have to select the exact location of what we are clicking. The S3 storage capacity is high, and the price is reasonable."
- "The free web and DB hosting could be improved. It could be faster when you download huge files from the S3 bucket to your local system. If the S3 bucket availability and performance could be improved, we would consider hosting our database over there."
What is our primary use case?
We use S3 buckets to store logs from the application side. The logs stay on the server for seven days. After that, we transfer them to the S3 bucket, depending on the application, and the logs help us correctly troubleshoot problems.
We can also host web apps in the historical bug bucket. If you have a domain name from Route 53, you can create a bug bucket over there and whatever is in the web applications folder. About 40 people at my company use S3.
What is most valuable?
You don't have to specify your clone, availability clone, or your locations. Everything's over there. They have a receipt for the instance where we have to select the exact location of what we are clicking. The S3 storage capacity is high, and the price is reasonable.
What needs improvement?
The free web and DB hosting could be improved. It could be faster when you download huge files from the S3 bucket to your local system. If the S3 bucket availability and performance could be improved, we would consider hosting our database over there.
For how long have I used the solution?
We have worked with AWS for two or three years.
What do I think about the stability of the solution?
I rate Amazon S3 nine out of 10 for stability.
How are customer service and support?
We usually don't need much help unless we experience some technical glitches. Amazon has helped us in those instances.
How would you rate customer service and support?
Positive
How was the initial setup?
You can deploy the solution in under 10 minutes.
What's my experience with pricing, setup cost, and licensing?
The price is based on the size of your files and how long they will be retained. If you want something like a grade 2 segment and 10 GB of data transfers, it's around $0.5.
Which other solutions did I evaluate?
We use S3 because all of our applications are on AWS. We have to use everything on the same cloud platform. The cost will be too high if you need to configure things to work across multiple cloud providers. It's highly complicated and expensive to set up cross-routing.
What other advice do I have?
I rate Amazon S3 eight out of 10. It's highly stable, scalable, and cost-effective. I recommend S3 depending on the customer's requirements. It's good if you need to store a large amount of read-only data. It isn't for block storage that you need to edit, but it's good for storing application logs.
Which deployment model are you using for this solution?

Easiest to use compared to other solutions, and can store different file formats
Pros and Cons
- "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."
- "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."
What is our primary use case?
We use Amazon S3 for storing images and documents. We use the solution for all file formats, and Amazon S3 gives us back URLs rendered on our end users' laptops.
What is most valuable?
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.
What needs improvement?
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. It takes some time to receive the file back. In the downloaded format, the file gets compressed.
For how long have I used the solution?
We have been using Amazon S3 for almost five years on many projects.
What do I think about the stability of the solution?
The stability of Amazon S3 could be better. Though it's better than Google stability-wise, the rendering needs improvement.
What do I think about the scalability of the solution?
There's no complaint about the scalability of Amazon S3 because it's more of a pay-as-you-go solution. You have to pay when you exhaust your storage, and the cost is a little higher, but there's no issue scaling the solution.
How are customer service and support?
Amazon S3 customer support is good. The support team sometimes waives the technical consultation fee, unlike Microsoft Azure and GCP, which charge you for every consultation, even when you try to solve the issue or DIY it.
Sometimes, Amazon S3 support gets delayed, but Amazon has great engineers who come up with solutions to your issues rather than wasting time.
How was the initial setup?
Amazon S3 has a straightforward setup. It's simple because it's just a plug-in, so it takes little time to set up.
It only takes two hours to set up Amazon S3. You use the Chrome browser on your phone. It's as easy as that, so every developer knows how to do it. You deploy Amazon S3 manually. It's a simple process. You sign up, take a storage folder, and then link the folder to your project. It'll take two hours, and that's it.
What's my experience with pricing, setup cost, and licensing?
The cost of Amazon S3 could be better. The solution needs to be less costly. As the number of data increases, you'll pay more for Amazon S3. It's around $200, which is okay, but my company uses it less often. For a file storage solution, Amazon S3 is expensive, though it would still depend on the project. It's more of the storage charge that needs to be lowered. Usually, Amazon gives you up to five TB free. Suppose Amazon charges you $200, that's fine, but it doesn't feel very justifiable, though there's no question in terms of the abilities of Amazon S3.
There's no extra cost for Amazon S3 except for personal storage.
What other advice do I have?
My company has hundreds of customers using Amazon S3.
I recommend Amazon S3 to others because Amazon has an IT cloud-first approach. It has microservices that could benefit your organization because, development-wise, it's outstanding. It has more reliability and stability. Amazon S3 boosts performance, which saves you time. Though it comes with a premium price, with the time saved, the solution can help grow your business faster. Before you even start using Amazon S3, I recommend seeing the available microservices and looking into what Amazon is trying to improvise and build so that you can use it for new projects and save on time and cost.
My rating for Amazon S3 is eight out of ten, but if the rendering speed, stability, and performance based on file size are better, I could give the solution a higher score.

Serves as repository for storing objects such as images and file with lifecycle policies
What is our primary use case?
We use Amazon S3 primarily as a repository for storing objects such as images and files. It serves as a storage solution where we can efficiently save and manage the data we collect.
What is most valuable?
Lifecycle policies in Amazon S3 is an important feature because they help manage transitions effectively. We can monitor how frequently objects are accessed and transition them to more cost-effective storage tiers. Additionally, the security architecture, including access control policies, is crucial for protecting our data. These three features—lifecycle management, cost-effective storage transitions, and robust security
What needs improvement?
From a pricing perspective, there’s still room for improvement, especially for smaller or startup entities that are very cost-conscious. If Amazon could repackage their S3 products to be more affordable and appealing for these smaller users, it could attract more customers, particularly at the lower end of the market.
What do I think about the scalability of the solution?
You can easily add more space as needed, and you can leverage the available metrics to set up alerts for when utilization reaches certain thresholds. It is highly scalable.
Our internal staff population exceeds one hundred. However, the number of clients accessing the application has surpassed ten thousand and continues to grow.
How are customer service and support?
There are occasional support issues where parts of the application might misbehave, often after scheduled upgrades. When this happens, we need to raise a support ticket. However, the team has been very agile in addressing these issues and quickly resolving them.
How was the initial setup?
The initial setup is straightforward. I have a DevOps team that handles the setup and management tasks. By the time I joined, a lot of the S3 configurations were already in place. For the few instances where we needed to set up S3, it involved just a few clicks. As the Chief Technical Officer, I focus on architecting solutions and providing guidance, while the DevOps team implements them. Overall, the process has been seamless.
What other advice do I have?
For disaster recovery, we're just starting to implement our strategy. Amazon fulfills its part of the shared responsibility model by providing highly available infrastructure, including data redundancy and regional instance deployment. Their infrastructure is designed to support high availability, which aligns with their disaster recovery stipulations. We’re still in the process of testing our own disaster recovery plans, including running full-scale disaster scenarios to ensure we meet our recovery time objectives (MTTR) and recovery point objectives (MTTD). Although we haven't experienced any outages or data loss since starting operations, we are content with Amazon's disaster recovery infrastructure and will continue to build and test our own processes at our own pace.
Overall, I rate the solution a nine out of ten.

It's more stable and high-performing than its Azure counterpart
Pros and Cons
- "I've also used Azure's tool, and S3 is far more stable I haven't seen the same issues on AWS that I'm having on Azure. Amazon CloudFront is way faster. The websites are loading way faster than when you do it on Azure CDN."
- "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."
What is our primary use case?
I'm a consultant who provides services for companies of various sizes here in South Africa. Our company is still small, with only about 20 clients. I use S3 for hosting my websites and other storage services. S3 can be used for static and dynamic websites as well as file storage. In terms of dynamic websites, I use S3 in addition to other technologies in a computerless environment. In other words, I don't need a virtual machine to have a dynamic website hosted on Amazon Web Services.
What is most valuable?
E3's most valuable feature is CloudFront.
What needs improvement?
You need to do some things to make the files and updates immediately accessible. If you don't know those steps, you will wait forever for your updates to take effect or be seen by the public.
That is the only area where a newcomer might get frustrated with hosting on S3. The files are available immediately when they are first deployed, but it takes some time when they make changes if you don't understand the simple procedure you need to follow for it to happen immediately.
The process needed to show updates immediately is a problem. You have to go somewhere to delete whatever is propagated and restart the propagation somehow. That is the only issue that I think they could fix with hosting on S3 as far as websites are concerned.
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.
For how long have I used the solution?
I've been using S3 for about three years
What do I think about the scalability of the solution?
It's a cloud service, so our scalability is good. I haven't had any issues. At the same time, I haven't had a situation where a client needed to expand the footprint of their site tremendously. I don't have massive clients like Netflix.
How are customer service and support?
I was never in a position where I needed to request AWS tech support.
Which solution did I use previously and why did I switch?
I've also used Azure's tool, and S3 is far more stable I haven't seen the same issues on AWS that I'm having on Azure. Amazon CloudFront is way faster. The websites are loading way faster than when you do it on Azure CDN.
Another advantage of S3 over CDN is the fact that I can deploy my websites on Amazon S3 with the root domain and the sub-domain loading the website. When using CDN, you cannot load the website with the root domain.
How was the initial setup?
In the beginning, it wasn't easy. S3 was a little cumbersome when I started using it. With updates, it became easier to set up static websites. However, deploying dynamic websites in S3 is still difficult. You need to take notes on what you're doing so you can do the next dynamic website.
The deployment is quite fast. You upload files, and that's it.
What's my experience with pricing, setup cost, and licensing?
There a no license fees. E3 is a cloud service, and you pay as you go. Your encryption licenses are free, so you only pay for the storage you're using. It's extremely inexpensive.
What other advice do I have?
I rate Amazon S3 10 out of 10. S3 is highly cost-effective, so I would definitely recommend it.
