Amazon S3 Valuable Features
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.

One of the most valuable features of Amazon S3 is its cost optimization. Lifecycle management allows objects to transition between different storage classes over time, helping to reduce costs. Additionally, Amazon S3 supports all kinds of storage mediums, be it files, folders, videos, or images. Another valuable feature is versioning, which offers data management by maintaining multiple versions of objects.

Amazon S3 is easily scalable and provides fantastic performance, especially in comparison to other cloud solutions like OCI and Azure. Its availability is high, almost at 99%, which is important for ensuring reliable access to stored data.

One of the benefits is being a global service, so it can be accessed from anywhere. From a features perspective, the ability to catalog data is beneficial.
It automatically moves data that is not frequently accessed to a less expensive archive over a set period, which is amazing. Its stability and scalability are also impressive, as it allows for increased storage space according to demand. I've never had any stability issues with S3.

The most valuable feature of Amazon S3 for me is static deployment; it doesn't charge much, and I can integrate CloudFront for DNS and routing. It is very useful and affordable.
Another valuable feature is versioning, which is critical for data management, allowing data recovery. Moreover, the life cycle policy feature is useful as it automatically manages data, making storage efficient.
View full review »The best thing about S3 is the security. I can enable encryption at rest using a KMS server, a key management server. Key management servers encrypt data, and you need the key to decrypt it. Without the key, you can't access the data. Amazon allows you to use your own servers or theirs. They offer Amazon encryption, which you decide on when you create the bucket. The bucket also has all the other features like versioning.
We can do versioning and life cycles. The biggest plus for me as a storage admin is the different tiers: standard, infrequent access, Glacier, and Glacier Deep Archive. The differences between these tiers are cost and data retrieval speed. Standard tier data is considered "hot," meaning it's accessible anytime, but it's expensive.
If you want to archive data you won't need often, or if you have ample time to retrieve a backup, the most cost-effective option is Glacier Deep Archive. It's very cheap, but the disadvantage is that when you request data, it takes up to 24 hours to become accessible.
There are no limitations on how much you can store, but the biggest limitation is that you cannot use Glacier Deep Archive from the console. You can't go into the AWS console and copy something directly into Deep Glacier, but you can do it from the command line. If you have programmatic access, there's a command to put data directly into Glacier Deep Archive.
We don't use anything AI on AWS right now. The AI stuff isn't really too useful for us yet. We're just playing around with Copilot from Microsoft, which is more on the Azure side. We haven't leveraged any AWS AI stuff yet. We've basically just been playing around with Amazon Bedrock, but haven't done anything in production with it.
View full review »The most valuable features of Amazon S3 include scalability, durability, reliability, security, access control, cost-effectiveness, performance, speed, data management, analytics, static website hosting, seamless integration with other AWS services, and budgeting features.
I find the cost-effective models particularly suitable for our needs. The performance with high-speed data retrieval and support for large file uploads is crucial. Security measures like encryption, access controls, and the block public access feature are also important.
Another useful feature is the MFA delete function that prevents accidental and malicious data deletions.

Amazon S3 is scalable and available. It's particularly useful for archiving data; I can configure it to keep files for six months before archiving them to Glacier. This flexibility in retrieving data or storing it makes it valuable.
View full review »Amazon S3 offers multiple beneficial features. One advantage is static web hosting, which eliminates the need for a dedicated server. We also have S3 for storage, where we can upload necessary files for processing.
Furthermore, it supports an SFTP service, where we set up an SFTP server on top of S3 and use credentials to transfer data from remote locations.
S3's lifecycle policies are also crucial; they automate the deletion or downgrading of files that are no longer needed. Moreover, we can set permissions to restrict or allow user access to the data.
Using S3, we can load data into databases and trigger AWS Lambda functions, which enhances our operational flexibility.

Normal file system storage is very limited when you want to store additional objects. The concept of S3 is to give you the option to have sharing from multiple users. They can share content among various users in a file system. It has the capacity to scale and to accommodate more files than a normal file system. This solution can really scale according to demand and you pay according to your consumption.
