Featured Reviews

Vagner Martins - PeerSpot reviewer
Enhanced data security with seamless integration and static website capabilities
S3 is a great service offering numerous possibilities. It allows for storing objects and files of various types. I appreciate its capability to create static websites and integrate with services like CloudFront, EC2, and DynamoDB. Despite being focused on security, I leverage features such as cryptography and integration with CloudTrail.
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.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The best thing about S3 is the security."
"It's reliable and stable."
"Easy to use, very intuitive, fast, and quite flexible."
"The solution is easy to use for anyone with minimal technical knowledge."
"Amazon S3 is scalable and available."
"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."
"We can easily connect to the AWS resources."
"The solution's most valuable feature is its security, as it does not provide public access."
"Google Cloud Storage is easy to use, and it's free. I also enjoy the speed I am able to share with family across the globe. The storage is synced."
"I could store any type of file using the solution."
"There's no implementation process."
"On the phone, I appreciate how seamless it is."
"Everything I store in the solution is available on all of my devices."
"The most valuable features of Google Cloud Storage include easy API integration for querying, downloading, and uploading files."
"Google Cloud Storage's most valuable features are that it's easy to use and navigate, and it's not expensive."
"The most valuable features of Google Cloud Storage are the ease of use and I can share files with my colleagues."
 

Cons

"When we need to find the queries there is no user interface, it is the only textual format that is bulky. If we need some data we will use Athena for queries and we will get results. When comparing this solution to others, such as DataDog, they provide a wonderful UI, and user-friendly dashboards, and many other features that this solution is lacking."
"Maybe it could be a bit cheaper."
"There's a lot of complexity."
"The service could improve by offering mobile backups, which would be great since using Google Backup is costly."
"The tool helps us with data backup storage of payment files and helps us avoid issues with clients when we miss the data. For instance, in the payment file of my Google client, you can find details of one-to-one transactions like the payment information on the file header, payment ID, payment client ID, group headers, etc. We get these details into the file format of ISO which is the accepted format at JP Morgan & Chase. Once we get the file format, we process it through S3."
"I would like there to be more support without needing to use Transfer Family."
"The down side is the web app should be aware of all the features that S3 provides in order to leverage its full potential."
"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 storage could be improved to manage it a bit better. Google Cloud Storage could be more secure, but the security features are okay."
"Having more storage space would be an improvement."
"Google Cloud Storage can improve by having better integration and migration tools."
"The solution must provide some accessibility features."
"Google Cloud Storage could be improved if they provided more free storage for free accounts."
"I would prefer more support for alternative operating systems like DSD. The performance could be better because sometimes there are glitches. The price could be better."
"Sometimes, I'm not too fond of privacy policies, especially when using certain features like Gemini AI, where agreeing to the terms might mean losing access to your history. One area for improvement is document retrieval—sometimes, it's hard to find documents because the file names aren't always recognizable, and the preview feature could be more efficient. Maintenance for Google Cloud Storage is minimal, but it would be helpful to have a tool that automatically removes duplicate versions of files to save space. The file management in Google Cloud and Workspace isn't very straightforward, which could be improved."
"It is stable, but it can always be more stable."
 

Pricing and Cost Advice

"The solution is very inexpensive at 50 cents per gigabyte, per month."
"I know it is very inexpensive compared to other solutions."
"The tool is not too expensive considering the various pros."
"The price is okay."
"The price of Amazon S3 depends on various variables. However, the price overall is fair."
"One can manage the price of the tool. The tool is worth the money if we want to store the data in Amazon S3."
"The cost varies based on the type of subscription you chose."
"The cost is based on the amount of storage required and if we exceed the data transfer rate across regions."
"The solution was very cheap compared to other products."
"I use the free version and have never paid for any extra storage. I have been able to manage in whatever free spaces are given."
"Regarding the cost of the solution, Google offers its users a pay-as-you-go model pricing."
"The solution comes with a cost once a person has exceeded a certain limit."
"It's an inexpensive product."
"The product pricing is reasonable."
"I just use the free storage that comes with Gmail. I have 15 gigabytes."
