Amazon S3 vs Azure Storage: What are the differences?

Developers describe Amazon S3 as "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. On the other hand, Azure Storage is detailed as "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 S3 and Azure Storage can be categorized as "Cloud Storage" tools.

Some of the features offered by Amazon S3 are:

  • 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.

On the other hand, Azure Storage provides the following key features:

  • Blobs, Tables, Queues, and Files
  • Highly scalable
  • Durable & highly available

"Reliable" is the primary reason why developers consider Amazon S3 over the competitors, whereas "All-in-one storage solution" was stated as the key factor in picking Azure Storage.

reddit, Instacart, and Lyft are some of the popular companies that use Amazon S3, whereas Azure Storage is used by Starbucks, Yammer, and Microsoft. Amazon S3 has a broader approval, being mentioned in 3194 company stacks & 1559 developers stacks; compared to Azure Storage, which is listed in 82 company stacks and 42 developer stacks.

    What are some alternatives to Amazon S3 and Azure Storage?
    Amazon Glacier
    In order to keep costs low, Amazon Glacier is optimized for data that is infrequently accessed and for which retrieval times of several hours are suitable. With Amazon Glacier, customers can reliably store large or small amounts of data for as little as $0.01 per gigabyte per month, a significant savings compared to on-premises solutions.
    Amazon EBS
    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 EC2
    Amazon Elastic Compute Cloud (Amazon EC2) is a web service that provides resizable compute capacity in the cloud. It is designed to make web-scale computing easier for developers.
    Google Drive
    The Drive SDK gives you a group of APIs along with client libraries, language-specific examples, and documentation to help you develop apps that integrate with Drive. The core functionality of Drive apps is to download and upload files in Google Drive. However, the Drive SDK provides a lot more than just storage.
    Microsoft Azure
    Azure is an open and flexible cloud platform that enables you to quickly build, deploy and manage applications across a global network of Microsoft-managed datacenters. You can build applications using any language, tool or framework. And you can integrate your public cloud applications with your existing IT environment.

    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.

    We use Azure Blob Storage for hosting all images on the Seen on Set website. These images are then geo-cached using Azure CDN.
