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

"Amazon S3 is reliable."
"S3 is well suited for both big and little data repositories of objects ranging from backup to archive to active video images and much more."
"Amazon S3 is a storage bucket service with good stability."
"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."
"I find the cost-effective models particularly suitable for our needs."
"We have cold storage here, and I think that's useful. When it comes to commercialization, it's cheaper to put data that you won't be using into the data storage. You only use a little bit of the data needed each day for your transition, so you pay less."
"The most valuable feature of Amazon S3 is the data transfer acceleration because it can enable fast, easy, and secure data transfer."
"The initial setup is not difficult or overly complex. It's very straightforward and easy to implement."
"Everything I store in the solution is available on all of my devices."
"Some of the most valuable features are how convenient and easy to use this solution is. It's very user-friendly and meets all my requirements."
"The most valuable features are the ease and accessibility of information."
"It's very practical and reliable."
"Any developer can study and implement what we do for cloud operations with the database side. It's not a big deal for developers. They can implement things using Google Cloud Storage."
"The combination of Firebase features, including storage, the Firebase database, and authentication, has been the most valuable. Firebase offers Google authentication, which is convenient for our needs. Additionally, Firebase provides email authentication and Gmail authentication, which are easy to set up and integrate into our applications."
"I would recommend Google Cloud Storage based on our experience, as it is fully reliable."
"The feature we've found most valuable is the ability to access our data anywhere, anytime."
 

Cons

"Sometimes we have to concentrate networks to a certain location, like the EU, for example. Therefore, if we set S3 in the EU region from the Middle East or Africa, the latency is an issue and we find it hard to connect to that S3."
"The major challenge is the inability to create more than ten policies."
"An encryption mechanism and storage optimization could be added."
"A feature that should be included is to find and provide a HIPPA compliant solution for the Presigned URL."
"The service could improve by offering mobile backups, which would be great since using Google Backup is costly."
"They should improve in the area of metadata curation."
"The solution's pricing should be modified to automatically expand storage based on prior usage."
"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."
"It is stable, but it can always be more stable."
"The solution could improve by adding an automatic removal of duplications feature."
"It could be made even more secure and allow for more storage."
"The security of this solution and its performance could still be improved."
"Google Cloud Storage is scalable, but you have to pay extra."
"Google Cloud Storage can improve by having better integration and migration tools."
"Google Cloud Storage could improve by increasing the storage from 15 GB. If I want to have more storage I need to pay extra money."
"I want the product to be available at a cheaper cost."
 

Pricing and Cost Advice

"The licensing is pay as you go, and I'm happy with the pricing."
"The cost varies based on the type of subscription you chose."
"The tool's price is a little bit high, but it is reasonable."
"This solution has reasonable pricing and a low cost."
"The price of Amazon S3 could be less expensive."
"The cost of storage is cheap. However, the cost to have a better interface can get expensive. We are using Athena for this purpose and if we did some heavy queries the cost will start adding up. When the Athena query is running, it will scan the bucket and they charge for how many GBs we are going to scan. The function of scanning has a lot of costs attached to it, this is a negative point."
"The solution is fairly priced."
"The cost depends on the data we access."
"We don't pay for a Google Cloud Storage subscription."
"The solution comes with a cost once a person has exceeded a certain limit."
"It's an inexpensive product."
"The price of Google Cloud Storage is reasonable when compared to other similar solutions."
"The solution was very cheap compared to other products."
"I am paying a yearly subscription fee."
"Better pricing would be helpful."
"They know that the pricing is comparable with Azure, AWS, and those other solutions like Amazon are cheaper, but they are not as flexible."
