### "The best storage solution in the planet"

April 9, 2022

5.0

Pros

inexpensive, fast and has a very high availability. And you can easily manage access control.

Cons

The only limitation that i see is that it gets a bit slower when writing/reading a very large number of tiny objects. It is recommended to use smaller objects instead

### "A robust cloud solution like a Swiss Army Knife"

January 27, 2022

4.0

In my previous company, it is one of the biggest ones in the e-commerce market in Europe, the whole infra-structure runs on AWS. I developed some back-end services and helped the management of this infra.

Pros

As the oldest cloud platform (since 2006), its abilities are bigger than its competitors like Google Cloud or Azure. Because of this, it has a product for any needs. Prices and free-tier options are so clear before starting the project, you can foresee your budget and probably bills. Also, both its official documents and community solutions are so rich. In case of a problem, finding a solution is so easy. With Terraform etc strong solutions, you can easily automate all processes. Also, AWS knowledge makes more money for the holders.

Cons

The side effect of having a lot of features, creating a service or product is from time to time so hard and you need to do something. For instance, to create a redshift instance, I had to visit more than 5 pages and without a guideline, I can not do again this. This increases the complexity. I have to use third parties to manage these.

April 18, 2023

4.0

Overall I am very happy with S3 as it helps to save on storage costs and new storage classes helps storage cost optimization even further.

Pros

Data replication, data security policies, data encryption, different pricing model for data storage

Cons

S3 is eventually consistent and cannot be used as HDFS storage solution.

### "Amazon S3 - Amazing Simple Storage Service"

October 20, 2018

4.0

Amazon S3 service is helping us in expending object storage on the go. It's helping us to save the money as Amazon S3 is very cost efficient. With the help of this we are also provide the security level that our customer need at the time joining or working with us.

Pros

Amazon S3 is a Simple Storage Service by Amazon Web Services to store the objects. Best thing in it is that it is highly scalable and no latency (except Glacier). It's extremely low cost service. You don't have to worry about security, durability and flexibility once you jump to Amazon S3 service. Best part in it that you don't have to end-up buying your own hardware storage space which need professional IT support. In Amazon S3 we should be paying for that service only that you are using it.

Cons

As it's a object storage space you can not install the OS or some dynamic site on it. managing the firewall is also a challenging part. We can not handle the file system of Amazom S3 service. You should be intelligent enough while selecting the S3 options or you should be getting extra load in your billing dashboard.

### "An Object Storage Solution by Amazon "

November 4, 2018

5.0

Amazon S3 scalability is the best thing helping for our business. It's also very cost effective as you don't have to pay what you don't want to use. In the today era AWS is a big giant and everyone want to host it services one best infrastructure.

Pros

Amazon Simple Storage Service also know as Amazon S3 is the one of the best service under the cloud solution with the most trusted name Amazon Web Service. Scalability is the one of the best feature we get under the hood of the Amazon S3 as you will never get out of space one the main time when you actually need the space and scale it back when we don't need it. Billing cycle is also very flexible and only charge you what you use. Operation Team can handle it and work under this is also infrastructure is more transparent.

Cons

Amazon S3 provide the object storage we can not run website all on it. It need helping hand from it's sister services like CloudFront, EC2 and RDS or Dynamo DB to make it really work. Managing firewall for it also one of the challenging part as you do not want the loophole in your storage solution.

### "S3 is where the Internet stores its stuff"

April 17, 2019

5.0

Amazon S3 has proven to be the best tool to use when storing application-related artifacts, with great programmatic integration through its powerful SDKs.

Pros

S3 has become the go-to standard for online artifact storage. It provides a great deal of options, from simply storing and receiving files, to hosting websites to programmatically maintaining application storage. Through effective and highly advanced security policies, S3 allows you to ensure no one else gets access to your data. The amazing integrations with different programming languages and frameworks via client SDKs allows programmatic integration with practically any software application that you may build.

Cons

The various options and configuration settings associated with setting up a simple S3 bucket can sometimes be overwhelming, and it may be hard to find the best fit for each situation unless you're an AWS expert.

### "A Simple Storage Service for OBJECT STORAGE."

January 6, 2019

5.0

Amazon S3 is the one the best and cost effective storage solution in the market. Storage management and monitoring is also easy can monitor using the Amazon CloudWatch. The Different storage class like S3 Standard-IA, S3 One Zone-IA, S3 Glacier Glacier Deep Archive help to reduce the cost of the storage if used effectively.

Pros

Amazon S3 is an object storage service. It is highly scalable and data availability is also very good of all the different availability zones. Amazon S3 provide the 99.999999999 % (11 times 9) durability. It is the cost-effective storage as we can storage the objects in different Amazon S3 storage class. Best part in it is the old data move automatically move to the low cost storage class based on the access frequency. The cross-Region replication is helpful in to move the data into the local region to reduce the latency.

Cons

Amazon S3 should come up with the auto sync with the local drive option. Managing firewall for Amazon S3 is one important part and should be setup carefully AWS also help and provide suggestion on it but we should not follow it always. Buckets on Amazon S3 also helpful in running the low cost storage. We can not run a complete dynamic website on it.

### "AWS storage solution"

March 12, 2022

4.0

I have used S3 in integration with other AWS services mainly to store files that are required for processing and also used S3 as an archival solution.

Pros

It has a good set of features with respect to access controls, encryptions, version control, event notifications, replications to other buckets. Overall it is a great storage solution and designed keeping various use cases in mind.

Cons

As the size of s3 grows there is no way to filter the files using the console, you may have to resort to using other services to search the files with s3 or programmatically search them within an s3 bucket.

### "S3, like all of AWS, is a big sprawling powerful product"

May 1, 2018

5.0

Pros

S3 is absolutely an expert tool, and as such is incredibly powerful. We use S3 throughout our workflow in a bunch of different places, and it solves a number of problems for us wherever we need to put files online (whether temporarily or permanently). For certain types of hosting and usage, the pricing is so low you can essentially forget that it costs anything and throw whatever you want at it.

Cons

The level of complexity in S3 is quite high, so even a process like setting permissions on a bucket feels like passing through some sort of inscrutable bureaucracy to some degree. While many AWS users are likely domain experts, for the rest of us who lack the time (or inclination) to dedicate as much time to learning the system, S3 can have an extremely steep learning curve and some byzantine ways of doing things.

### "Great Cloud Storage"

June 25, 2022

5.0

We began using S3 to store many different business documents instead of utilizing on-prem storage. It’s been easy to implement into projects and apps once the buckets have been set up.

Pros

Super easy to set up and implement into new or existing projects. The SDK makes implementation a breeze.

Cons

Setting up the bucket can be confusing when it comes to access permissions. Learning more about the setup of AWS resources would be recommended.

### "S3 cloud storage review"

October 9, 2019

5.0

Overall S3 is economic and reliable cloud storage which I'm using everyday. Introducing some more features like mentioned in Cons above could make it outstanding and it would be a win win over other products.

Pros

\- It's fast and probably has cheap options available for you based on your need, like if you just want cloud storage but with less feature you can chose accordingly (Glacier or S3 bucket). - aws cli client/commands are really helpful which makes life easy and fast to list/analyze objects recursively. - you can easily set permissions to your buckets/prefixes/paths using cloud formation templates which is great to grant specific user specific permissions. - easy to set up versioning/auto deletion policies on your data so you don't have to worry about storage cost.

Cons

\- The UI is not as helpful as it needed to be sometime. like the filtering/listing of object within your S3 bucket is sometimes weird, it only shows 300 objects per page and you can't control them to list more or less. - you can only visualize an object/file within the UI using sql if it's < 128 MB. If it exceeds 128MB there is no way to visualize this object within the UI and you've to create external table to visualize it or you download it local.

### "Scalable storage for scalable apps "

April 15, 2020

5.0

Pros

In these days for AI, Big Data, machine learning you need data storage which is reliable in terms of your data always be available when you need it, when amazon launched Africa region servers in Cape Town it even made sense for us to use AWS for storage services and its very affordable prices as you only pay for what you use.

Cons

You really need to know what you are doing specially when comes to using S3 for machine learning some data sets might just increase your data storage you will need to optimise your data so as to reduce cost in storage.

### "Efficient and easy to use Distributed file Storage System"

March 23, 2020

5.0

over all it is a pretty good experience

Pros

s3 auto rewrites the file, need not handle if file exists delete then write etc.. it gives ability to create static web pages, can be used as a redirecting page it can be used in sql copy commands, where a query generated results can be stored into the s3 file in different formats can set different permission models to a file or a set of files in a bucket has Java jar's, python support and ubuntu command line support so that it can be automated through programming

Cons

the file or folder name cant be a prefix sub string of other file name example : if i have file1.csv and file1.csv.zip if i delete file1.csv through code , it deletes both the files and the static web hosting dont support https, for this we have to do a workaround

### "Best Cloud Storage"

May 4, 2022

4.0

It came with advanced features. used it with AWS EC2 instance for backup purposes an ERP website

Pros

They claim 99.99999999999 which means there is a chance after million of years that my data may loss so we can put sensitive data in an S3 bucket for safely secure.

Cons

S3 Glacier service is cheap but once we put data it is taken several hours to restore of getting data back if you had emergy restore there is no chance to get it early.

### "A Easy and Simple Configurable Cloud Storage"

August 16, 2019

5.0

We use AWS S3 for hosting the Statics websites of different departments as well as storing the software and documents.

Pros

First thing I like the most is S3 is very simple to configure and use. It is very highly secure, reliable, durability at a highly cost-effective price than other competitors. It is very easy to set up static websites and has faster load times. You can share your documents with just a single click.

Cons

Copying the files onto the server is little confusing as we need to install the command-line software (aws cli) to access the files on S3.

Reason for choosing Amazon S3

The only reason for choosing S3 is that comes with Amazon AWS account as storage service and it comes on one account. The prices are very reasonable and can host the static files for the different websites easily.

### "A Bit Daunting at First, But Powerful Enough for Wide-Ranging Uses"

September 5, 2019

5.0

Amazon S3 is, of all of the major public/private storage services on the enterprise level, probably the easiest and most-reliable. For most basic uses, it excels at being as easy as managing files on your own web servers. Additonally, when combined with Amazon Route 53, it can be a rapid static web serving option. However, when you start getting into advanced security options or attempting to ensure that your files are only accessible to your own applications, you need to be very adept at studying Amazon's specific ACL formats, lest you lock yourself out or, even worse, expose your data to public download. Nonetheless, there's probably nothing better in this area, and the time that you spend learning these skills is well worth it for this service.

Pros

Flexible storage options, integrates well with other Amazon Web Services options, able to be used for static web hosting, fine-grained security settings

Cons

Advanced security settings are often hard to configure, pricing is not always clear and it is possible to quickly accrue large fees when testing

Reason for choosing Amazon S3

Better pricing, better availability zones

### "Amazon S3 Review"

February 13, 2020

5.0

In our project, we are using Amazon web services for deploying and running our code and services over the cloud, so the deployment requires placing the Jar and War file in the S3 bucket. And then restricting the access of the S3 bucket using group and roles this makes are tasks easy for proper permission access to users and applications.

Pros

Amazon S3 provides a platform where we can restrict users by controlling the permission using groups and individual permission allocations. This platform provides a facility where we can share things with people based on the public and private level requirements.

Cons

As such it is not a point to discuss or list as cons but the unique name of the S3 bucket across all the regions where we do not create bucket based on any reason disturbs me. Rest as such I did not find anything as negative about the product.

### "Amazon S3 for Big data"

December 12, 2018

3.0

Pros

Amazon S3 is the best file system in the space that deals with Big Data. Amazon S3 is able to host big files in an elastic way without worry about out of space. Amazon S3 assigns user roles to each individual bucket. The administrator can define read and write access policies for the entire bucket.

Cons

The first issue in Amazon S3 is that it does not provide email notification to the users in case that a bucket or a sub-directory has been changed by adding/deleting files. Also, integrating S3 with SSO is really challenging. Regardless the fact that Amazon S3 deals with Big Data, the Amazon S3 client API has many problems when a file size is greater than 5GB. A lot of workarounds should be done to split big files into parts and merge them successfully.

### "High available and durable storage services"

July 8, 2019

5.0

We use S3 as our primary storage to store data for our applications which deploy on AWS. S3 is used to store application logs, application input, and output data with large size which work together with AWS dynamoDB to store S3 object key, Application initial data

Pros

Amazon S3 provides highly scalable, reliable, fast, inexpensive data storage. You could store an almost unlimited amount of data in the cloud with object size up to 5TB, the object is replicate stored on the cloud to keep your data very durable and reliable. S3 provides multiple store option from Glacier to Infrequency access with different prices so you could choose which storage option you need to reduce the cost or increase your data access speed. S3 API and the UI is simple and easy to learn with a very good document and well support from AWS. S3 is well integrated with other AWS services such as IAM, EC2, SQS to provide a storage solution for application deploy in AWS cloud

Cons

The namespace is unique cause some difficulties when we create an object, bucket from the application. Also, it does not have much support real folder so we unable to define security or policy for folder level

### "S3 - Low cost cloud storage and best for static content"

December 12, 2019

5.0

We use S3 with Athena to parse data we receive from our customers. Using S3 and Athena, we were able to build a model which can automatically populate a set of tables from the CSV files.

Pros

Simple idea, so easy that any one who uses a PC can easily understand the buckets, navigation, sharing of content. Behind the scenes there will seamless redundancy, 99.9999999% availability and so on. Best of all it is not expensive

Cons

Literally nothing. The cost is cheap and we cannot complain about that. Ideal for static website content where you dont even have to spin up an Application server.
