Amazon EBS vs Amazon S3: What are the differences?
Amazon EBS: Block level storage volumes for use with Amazon EC2 instances. Amazon EBS volumes are network-attached, and persist independently from the life of an instance. Amazon EBS provides highly available, highly reliable, predictable storage volumes that can be attached to a running Amazon EC2 instance and exposed as a device within the instance. Amazon EBS is particularly suited for applications that require a database, file system, or access to raw block level storage; Amazon S3: Store and retrieve any amount of data, at any time, from anywhere on the web. Amazon Simple Storage Service provides a fully redundant data storage infrastructure for storing and retrieving any amount of data, at any time, from anywhere on the web.
Amazon EBS and Amazon S3 belong to "Cloud Storage" category of the tech stack.
Some of the features offered by Amazon EBS are:
- Amazon EBS allows you to create storage volumes from 1 GB to 1 TB that can be mounted as devices by Amazon EC2 instances. Multiple volumes can be mounted to the same instance.
- Amazon EBS enables you to provision a specific level of I/O performance if desired, by choosing a Provisioned IOPS volume. This allows you to predictably scale to thousands of IOPS per Amazon EC2 instance.
- Storage volumes behave like raw, unformatted block devices, with user supplied device names and a block device interface. You can create a file system on top of Amazon EBS volumes, or use them in any other way you would use a block device (like a hard drive).
On the other hand, Amazon S3 provides the following key features:
- Write, read, and delete objects containing from 1 byte to 5 terabytes of data each. The number of objects you can store is unlimited.
- Each object is stored in a bucket and retrieved via a unique, developer-assigned key.
- A bucket can be stored in one of several Regions. You can choose a Region to optimize for latency, minimize costs, or address regulatory requirements. Amazon S3 is currently available in the US Standard, US West (Oregon), US West (Northern California), EU (Ireland), Asia Pacific (Singapore), Asia Pacific (Tokyo), Asia Pacific (Sydney), South America (Sao Paulo), and GovCloud (US) Regions. The US Standard Region automatically routes requests to facilities in Northern Virginia or the Pacific Northwest using network maps.
"Point-in-time snapshots" is the top reason why over 34 developers like Amazon EBS, while over 589 developers mention "Reliable" as the leading cause for choosing Amazon S3.
Airbnb, Spotify, and Netflix are some of the popular companies that use Amazon S3, whereas Amazon EBS is used by Airbnb, Medium, and Instacart. Amazon S3 has a broader approval, being mentioned in 3230 company stacks & 1611 developers stacks; compared to Amazon EBS, which is listed in 179 company stacks and 47 developer stacks.

Insanely low prices, quite easy to use, and they're fast. Plus they provide great support. And they're integrated with other AWS services, like CloudFront.
Seriously, this is the best service of it's kind out there.
We store the software components that CloudRepo stores for its customers here for the following reasons:
- Data is Encrypted at Rest
- Data is stored across multiple physical locations
- Pricing is competitive
- Reliability is industry leading and our customers need to be able to access their data at all times list text here
In October 2008 we moved to using scribe (now a custom branch), which has served us very well over the past 5+ years that we’ve been using it. We take the logs scribe aggregates and move them into Amazon S3 for storage, which makes using EMR on AWS seamless.
S3 serves as zero-knowledge temporary storage. Files are encrypted in the browser before being uploaded in chunks to S3. When the target recipient downloads them the chunks are reassembled and decrypted in the browser. Files expire after a week and the encrypted chunks are permanently deleted from S3.
Since we generate a static website for our website, AWS S3 provides hosting for us so that we don't have to run our own servers just to serve up static content.
The pricing is great as you only pay for what you use.
This object storage is always evolving and getting harder to explain. We use it for 1) hosting every static websites, 2) datalake to store every transaction and 3) query with Athena / S3 Select.
Opstax uses EBS storage to store images, snapshots and to write any data we need to keep when an instance is no longer.
