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.
