Diverse features and affordability drive effective resource management
Amazon EBS offers diverse features. It can be used for multi-purpose storage, supporting single, multiple, or heavy loads. It has different types for various use cases, allowing me to choose based on my specific requirements. The primary advantage of Amazon EBS is affordability compared to other solutions like EFS or FSX. It acts as a hard drive for servers, making it essential for operation.
MuhammadAzhar Khan - PeerSpot reviewer
Auto-scaling capabilities enhance file management while reducing downtime
The most valuable feature of Amazon EFS is its auto-scaling capability. It's really easy to configure EFS by just creating it and running a command to directly configure it with my servers. It supports unlimited use, and charges are applied based on the file usage at the end of the month. The solution offers reduced downtime and increased durability through its auto-scaling features.

Quotes from Members

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

Pros

"Amazon EBS is a cost-effective solution, where I pay as I go, making it a favorable option."
"Amazon EBS is very stable."
"If EBS is attached to an EC2 instance, it allows secure document storage."
"EBS can handle Apex, which helps us manage many issues. EBS is easy to use and has high performance."
"Amazon EBS is perfectly serving its purpose, and I absolutely recommend it to others."
"The most valuable feature of the solution stems from the fact that during the deployment, the tool indirectly provides our company with resources for our core side and cloud-based resources."
"The most valuable feature is its scalability. I can easily scale the block from terabytes to gigabytes."
"When it comes to valuable features, ease of use would be number one."
"We haven't seen any downtime or challenges when using the services."
"We are not that big of a cloud user. We just use it for the storage of our bytes. The most valuable aspect is the storage."
"We can run code and deploy it whenever we want."
"Elastic File Systems allow me to share data, provision, and manage capacity and performance in AWS."
"Amazon EFS (Elastic File System) is secure as it is used under VPC."
"The solution is scalable."
"Amazon EFS is extremely stable, as it is managed by AWS."
"Elastic File Systems allow me to share data, provision, and manage capacity and performance in AWS."
 

Cons

"Regarding EBS, if an instance is terminated, the volume is also deleted, which leads to data loss."
"Amazon EBS could improve by offering immutability of the data."
"I would like EBS to have no limitations, similar to stream-like block storage, which can accommodate an unlimited amount of sales."
"It is hard to access EBS volumes in different Availability Zones (AZs) because most EBS volumes are created in a single AZ."
"Having more flexibility in resizing, especially scaling down, would be beneficial."
"I feel that there are some concerns when it comes to the accessibility area of the product where improvements are required."
"There is room for improvement in AWS support."
"There is room for improvement in terms of file storage. Recently, we had a scenario in which, in a file share, we had increased the IOPS capacity; this was for the production environment."
"Elastic File Systems can be expensive due to the nature of data transfer costs, using services like SSTP, and potentially being costly in a rate-shift context."
"When we faced some issues, the support team took a lot of time to resolve them."
"Around 80 percent of the features of Amazon EFS (Elastic File System) are available on Linux and not in Windows, making it a major drawback of the product."
"The product's stability has some shortcomings where improvements are required."
"It could be better in connecting with Windows Server instances."
"The initial setup requires prior experience and technical skills."
"It should be simplified. There are people who don't have cloud experience. It should be storage that we are able to just connect to."
"The platform's connectivity could be improved to be more comparable to S3 buckets, which offer better API availability."
 

Pricing and Cost Advice

"The product is low-priced than other solutions."
"The solution is quite costly."
"What I want Amazon to do is lower the price."
"On a scale of one to ten, where one is low price, and ten is high, I rate the price a seven."
"You need to pay additional costs for support."
"The solution is reasonably priced."
"It is a cost-effective solution."
"The pricing models may be for general purposes, such as Amazon EBS Provisioned IOPS Volume or Amazon EBS Cold HDD Volumes."
"The product's price depends on the services and the size and capacity at which it is used in a business environment."
"The main challenge with EFS is its cost, which is slightly higher compared to EBS or S3. For one GB or ten GB of data, S3 is much cheaper. EFS could cost around $30 to $50 per month for similar usage."
"It has flexible pricing. You are charged based on your storage."
"I would rate the pricing 7 out of 10."
"The product charges are based on the amount of data stored."
"The solution's price is mid-ranged."
"Amazon EFS (Elastic File System) offers a pay-as-you-go model, so whenever you use its services, you need to pay."
