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 most valuable feature of Amazon S3 is its flexibility as a solution to suit many different use cases."
"One of the benefits is being a global service, so it can be accessed from anywhere."
"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."
"The most valuable features of Amazon S3 are the accuracy and the life cycle policies, which help when moving from Amazon S3 to Amazon Glacier."
"It allows for storing objects and files of various types."
"The solution is easy to use for anyone with minimal technical knowledge."
"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."
"Cloud infrastructure is the most valuable feature."
"Everything I store in the solution is available on all of my devices."
"The solution offers versioning, which lets us work together efficiently on a single document. What I like most about Google Cloud Storage is its ease of use and the integration of all Google services. It's very efficient for work."
"The most valuable features of Google Cloud Storage include easy API integration for querying, downloading, and uploading files."
"The most valuable feature of Google Cloud Storage is that I can link with my PC."
"It's a stable enough solution."
"The solution is very flexible."
"The solution operates in the background and it is attached to my Gmail account. When I download files to my phone, such as pictures, they automatically go to Google Cloud Storage."
"Using this solution has improved the security of our data."
 

Cons

"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."
"The service could improve by offering mobile backups, which would be great since using Google Backup is costly."
"The major challenge is the inability to create more than ten policies."
"Sometimes, there is latency in getting data, especially if the file size is large. This could be improved."
"The support is better than other cloud providers but sometimes it takes a while to have a resolution to our issues."
"One thing would be automatic replication between buckets, some feature like that."
"The search option must be enabled in the UI to filter and retrieve files."
"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."
"It could be made even more secure and allow for more storage."
"They need more enhancements in the security features."
"While the solution seems to be secure, I worry that, with the cloud, there is a chance of hacking. It would be ideal if they could be more transparent about the processes they go through to keep our data secure in the cloud and on their systems."
"Here in the Philippines, we don't have direct support from Google. We have self-studied to learn the services."
"The product must provide less frequent updates."
"The solution only allows so much space for free."
"What would make Google Cloud Storage better is if it provided more storage."
"The solution is good, however, it would benefit from increased storage without the additional cost."
 

Pricing and Cost Advice

"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."
"I would rate the pricing a nine out of ten. Pricing depends on a particular class where you want save your objects. There are different classes when it comes to storage in S3."
"The solution is very inexpensive at 50 cents per gigabyte, per month."
"With S3 Standard, there is not a charge for deletion of objects."
"The tool's price is a little bit high, but it is reasonable."
"The cost depends on the data we access."
"Not many products in the market beat the solution in terms of quality or price."
"The tool's licensing costs are monthly and cheap."
"I am paying a yearly subscription fee."
"I pay monthly for Google Cloud Storage. It could be cheaper, but for now, it's okay."
"The product pricing is reasonable."
"In general, it's fairly priced."
"If one is cheap and ten is expensive, I rate the product price as a nine to ten out of ten."
"I just use the free storage that comes with Gmail. I have 15 gigabytes."
"It's about nearly $10,000 USD to use the services on GCP, however, Google gave us a good deal which is why we originally went with them."
"They have recently changed their pricing structures, it used to be free but now it is a paid service. However, I am on a monthly subscription and the price is reasonable."
