Azure Blob Storage is persistent cloud-based storage provided by Microsoft. Use this tag for questions *about* either how-to-use or problems using Azure Blob Storage.

Microsoft developed Azure Storage to support cloud computing and enable new scenarios for applications requiring scalable, durable, and highly available storage. In addition to making it possible for developers to build large-scale applications to support new scenarios, Azure Storage also provides the storage foundation for Azure Virtual Machines, a further testament to its robustness.

Azure Storage is massively scalable, so you can store and process hundreds of terabytes of data to support the big data scenarios required by scientific, financial analysis, and media applications. Or you can store the small amounts of data required for a small business website. Wherever your needs fall, you pay only for the data you’re storing.

Azure Storage is elastic, so you can design applications for a large global audience, and scale those applications as needed - both in terms of the amount of data stored and the number of requests made against it. You pay only for what you use, and only when you use it.

Azure Storage uses an auto-partitioning system that automatically load-balances your data based on traffic. This means that as the demands on your application grow, Azure Storage automatically allocates the appropriate resources to meet them.

Azure Storage is accessible from anywhere in the world, from any type of application, whether it’s running in the cloud, on the desktop, on an on-premises server, or on a mobile or tablet device. You can use Azure Storage in mobile scenarios where the application stores a subset of data on the device and synchronizes it with a full set of data stored in the cloud.

Azure Storage supports clients using a diverse set of operating systems (including Windows and Linux) and a variety of programming languages (including .NET, Java, and C++) for convenient development. Azure Storage also exposes data resources via simple REST APIs, which are available to any client capable of sending and receiving data via HTTP/HTTPS.

Azure Premium Storage delivers high-performance, low-latency disk support for I/O intensive workloads running on Azure Virtual Machines. With Azure Premium Storage, you can attach multiple persistent data disks to a virtual machine and configure them to meet your performance requirements. Each data disk is backed by an SSD disk in Azure Premium Storage for maximum I/O performance. See Premium Storage: High-Performance Storage for Azure Virtual Machine Workloads for more details.
