Amazon EBS vs Azure Storage: 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; Azure Storage: Reliable, economical cloud storage for data big and small. Azure Storage provides the flexibility to store and retrieve large amounts of unstructured data, such as documents and media files with Azure Blobs; structured nosql based data with Azure Tables; reliable messages with Azure Queues, and use SMB based Azure Files for migrating on-premises applications to the cloud.
Amazon EBS and Azure Storage can be categorized as "Cloud Storage" tools.
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, Azure Storage provides the following key features:
- Blobs, Tables, Queues, and Files
- Highly scalable
- Durable & highly available
"Point-in-time snapshots" is the primary reason why developers consider Amazon EBS over the competitors, whereas "All-in-one storage solution" was stated as the key factor in picking Azure Storage.
Instacart, PedidosYa, and Parse are some of the popular companies that use Amazon EBS, whereas Azure Storage is used by Starbucks, Yammer, and Microsoft. Amazon EBS has a broader approval, being mentioned in 178 company stacks & 47 developers stacks; compared to Azure Storage, which is listed in 82 company stacks and 42 developer stacks.
