Azure Storage implements the following four services:

• Blob storage: Blob storage stores unstructured object data, which can be text or binary data.
• Table storage: Structured datasets are stored in Table storage. Table storage is a NoSQL key attribute data store, enabling rapid development and fast access to data.
• Queue storage: In addition to providing reliable messaging for workflow processing, Queue storage makes communication between segments of cloud services available.
• File storage: Using the standard Server Message Block (SMB) protocol, file storage offers shared storage for legacy applications. Azure virtual machines and cloud services can share file data over application components using mounted shares. Utilizing the file service REST API, on-premise applications can obtain file data.
