Has reduced storage costs and improved data management through automated lifecycle and seamless service integration
The best features that Amazon S3 offers are high durability and availability with virtually unlimited storage, lifecycle management for automated tiering and cost control, versioning to retain and recover data changes, and integration with services such as Glue, Athena, EMR, Lambda, along with strong security via IAM roles, bucket policies, and encryption. These features help by ensuring data is always available, securely stored, and easily accessible for pipelines. Lifecycle policies reduce manual cleanup, versioning safeguards against accidental deletions, and integrations allow us to directly run analytics or trigger workflows without moving data around. Amazon S3 event notifications help automate tasks such as triggering ETL jobs or Lambda functions on new data arrivals, and features such as cross-region replication ensure data redundancy and compliance, while fine-grained access control makes it easy to manage permissions across teams securely. My organization has seen improvements in data accessibility, reduced infrastructure costs, and simplified data management through Amazon S3. We now have a unified scalable storage layer that supports analytics, backups, and migrations seamlessly, leading to faster workflows and better decision-making.

Cloud storage has simplified team data access and provides reliable, globally available redundancy
The first thing I find really useful about Azure Blob Storage is that it is a cloud service running on the cloud. Using cloud storage, all the things are actually running on the cloud and they are managed by the cloud vendor. Microsoft is managing the backend things. I am just monitoring and managing the things, and I do not need to think about the physical things, upgrades, and all those things. That is managed by the OEM, which is a good thing. Additionally, it is globally available anywhere, so there are advantages in communications with the clients and all those things from that side. The main benefit that Azure Blob Storage provides for me is redundancy. They have multiple types of redundancy from the storage perspective, such as local redundant storage and zone redundant storage. Data will be available anytime, and that kind of assurance they are giving us is actually the main reason I can say for the Azure perspective. Access is one area where Azure Blob Storage can improve, as they have multiple types of storage. In Blob Storage, they also have file shares and queue storage. I have not seen any issues with Azure Blob Storage right now, and the access features allow us to grant the minimum level of access to the users, so users can only read the data. I can say those are also good features from an Azure Blob Storage perspective, and I have not seen anything negative there.

Quotes from Members

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

Pros

"The multi-zone replication is great."
"Amazon S3 is easy to use and it is beneficial to use the CLI to make the backups. Since I use the CLI I do not have to do it on a web portal which is a big advantage because everything can be automatized. Automation can be done very well in Amazon S3."
"This solution is managed fully, and there is no need for upgrades or anything."
"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."
"Amazon S3 is very stable. I don't worry about data stored in the S3 bucket as it's safe."
"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."
"The main aspect we like is that it's been easy to use."
"This solution is good at storing historical data and we were using it for other purposes."
"Azure Blob Storage is globally available anywhere, allowing for good communication with clients and taking advantage from that side."
"The main benefit that Azure Blob Storage provides for me is redundancy."
 

Cons

"The main pain point that I have faced is the need for faster restore times from Glacier tiers, which could definitely be improved."
"The upload speed for data and documents is sometimes slow."
"Amazon S3 needs to simplify the backup features."
"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 initial setup was a bit hectic. Uploading data only allows for five GB chunks, creating challenges."
"The pricing and licensing are pretty complex."
"We would like Amazon to reduce the price of storage."
"The service could improve by offering mobile backups, which would be great since using Google Backup is costly."
"The initial setup for Azure Blob Storage is right now simple, but they could improve the implementation in the future, particularly around configuration, access-related management, and related things."
"A proper monitoring dashboard would help, allowing us to see the usage and IO utilization."
 

Pricing and Cost Advice

"The price of Amazon S3 could be less expensive."
"The license of Amazon S3 is based on volume, capacity, and time. The overall price of the solution could improve. The support has to be added if you want it at an additional cost."
"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 solution is very inexpensive at 50 cents per gigabyte, per month."
"The cost of Amazon S3 is good. The pricing model is based on the usage of the solution."
"The price of the Amazon S3 is low. The license model is based on what you use."
"The price of Amazon S3 should be reduced."
"The price of Amazon S3 depends on various variables. However, the price overall is fair."
