Azure Blob Storage

Massively scalable and secure object storage for cloud-native workloads, archives, data lakes, HPC, and machine learning
Overview

Scalable, highly secure, and cost-effective object storage in the cloud

  • Azure Blob Storage helps you create data lakes for your analytics needs and provides storage to build powerful cloud-native and mobile apps. Optimize costs with tiered storage for your long-term data, and flexibly scale up for high-performance computing and machine learning workloads.
  • Blob Storage is built from the ground up to support the scale, security, and availability needs of mobile, web, and cloud-native application developers. Use it as a cornerstone for serverless architectures such as Azure Functions. Blob Storage supports the most popular development frameworks, including Java, .NET, Python, and Node.js. It’s the only cloud storage service that offers a premium, solid-state drive (SSD)-based object storage tier for low-latency and interactive scenarios.
  • Multiple storage tiers and automated lifecycle management allow you to cost-effectively store massive amounts of infrequently or rarely accessed data. Replace your tape archives with Blob Storage and stop worrying about migrating across hardware generations.
  • Azure Data Lake Storage is a highly scalable and cost-effective data lake solution for big data analytics. It combines the power of a high-performance file system with massive scale and economy to accelerate time to insight. Data Lake Storage extends Azure Blob Storage capabilities and is optimized for analytics workloads.
  • Blob Storage meets the demanding, high-throughput requirements of high-performance computing (HPC) applications. It provides the scale necessary to support storage for billions of data points flowing in from IoT endpoints.

PRICING

Flexible pricing, including reserved options to meet your cloud storage needs

Choose from four storage tiers based on how often you expect to access the data. Store performance-sensitive data in the Premium tier, frequently accessed data in the Hot tier, infrequently accessed data in the Cool and Cold tiers, and rarely accessed data in the Archive tier. Significantly reduce costs by reserving storage capacity.

Frequently asked questions

  • A blob is a binary, large object and a storage option for any type of data that you want to store in a binary format.
  • A region is a set of datacenters deployed within a latency-defined parameter and connected through a dedicated, regional, low-latency network.
  • Take advantage of the data transfer tool in the Azure portal or compare different data transfer options.
  • Data in Azure Storage is encrypted and decrypted transparently using 256-bit Advanced Encryption Standard (AES) encryption. It is Federal Information Processing Standard (FIPS) 140-2 compliant.
  • Set your default account tier in the Azure portal. The Archive tier is available to General Purpose (GP) v2 and Blob Storage accounts and only available for individual block blobs and append blobs.
