Scalability Issues

Sentiment score
7.1
Amazon EBS is scalable and fault-tolerant, but scaling down is complex, needing improvement in autoscaling and troubleshooting.
Sentiment score
8.3
Amazon S3 offers scalable, flexible storage with strong security, though learning curve and costs may concern some users across sectors.
Amazon EBS is easy to scale up or down as needed.
Vertical scaling can be achieved by adding additional volumes whenever the created storage is insufficient.
All cloud solutions permit scalability, and this is an important feature.
Data placed in an S3 bucket is replicated across availability zones in a region, ensuring scalability and availability.
Amazon S3's automatic scaling has benefited me, as I don't need to plan storage requirements.
Amazon S3 is easily scalable and performs better compared to other cloud storage solutions.
 

Stability Issues

Sentiment score
7.8
Amazon EBS is praised for stability and reliability, with minor regional issues affecting lower-tier services and connectivity.
Sentiment score
8.1
Amazon S3 is highly reliable for large companies, though users note minor issues with data management and security configuration.
AWS provides infrastructure stability like data centers, ensuring high stability.
I have never had problems with its stability.
If the server is stable, then EBS is stable.
Transitioning between S3 storage classes, like moving data from the standard class to Glacier or Glacier Deep Archive, has been challenging.
Amazon S3 is highly stable.
 

Room For Improvement

Amazon EBS requires improvements in cost, scalability, latency, UI, and user experience, including auto-scaling and support.
Amazon S3's interface challenges user experience with complexity, security, performance, and pricing issues, needing improved management and integration features.
I would like EBS to have no limitations, similar to stream-like block storage, which can accommodate an unlimited amount of sales.
Deployment is not easy as it requires server downtime to map newly created volumes, impacting operations during additional volume additions.
There is a challenge of intermittent reachability with instances, where the product is sometimes available and other times not, which affects the development environment's stability.
An improvement could be associating the naming with personal accounts, allowing more familiar or desired names without conflicting with global conventions.
The practice of protecting data could be more streamlined or mandatory.
In terms of security, I struggled with setting permissions and access control initially.
 

Setup Cost

Amazon EBS offers flexible pricing but can be costly without careful management, especially for high IOPS or large snapshots.
Amazon S3's pay-as-you-go pricing is cost-effective but may increase with data retrievals and higher usage scenarios.
For SSD IOPS, you only pay $0.125 per gigabyte.
The pay-for-what-you-use model justifies the amount paid, with no extra or hidden charges.
Users are charged only for the data used, not for the allocated volume.
I've used the free tier and haven't been charged yet.
S3 offers multiple classes, allowing you to move data to cheaper classes for cost savings.
It is somewhat justified due to the benefits, but there is room for reconsideration.
 

Valuable Features

Amazon EBS provides scalable, flexible, and secure storage with high performance, durability, and cost-effectiveness, supporting diverse workloads efficiently.
Amazon S3 excels in availability, scalability, security, cost-effectiveness, and ease of use, making it ideal for data storage.
Amazon EBS is also scalable and provides high availability.
EBS provides vertical scaling options to add additional volumes when more storage is required.
Amazon EBS allows seamless changes to the instance type without affecting application availability.
Its stability and scalability are also impressive, as it allows for increased storage space according to demand.
I appreciate its capability to create static websites and integrate with services like CloudFront, EC2, and DynamoDB.
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.

Effortless disk expansion enhances EC2 efficiency with a straightforward setup
In a traditional setup, if you want to add a disk to legacy systems, you need to purchase, find the hardware vendor, and insert it, which is a lengthy procedure. With Amazon EBS, if you want to add an additional disk to an EC2 instance, you can simply attach an EBS volume by clicking through a few options, and it's done.
HenryAragon - PeerSpot reviewer
Offers different tiers, enable encryption but there's a lot of complexity
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.
