Data is then copied asynchronously to a single physical location in the secondary region.Īzure Storage includes different data services. Geo-zone-redundant storage (GZRS): data is copied synchronously across three Azure availability zones in the primary region using ZRS.Data is then copied asynchronously to a single physical location in the secondary region. Geo-redundant storage (GRS): data is copied synchronously three times within a single physical location in the primary region using LRS.Each availability zone is a separate physical location with independent power, cooling, and networking. Zone-redundant storage (ZRS): data is replicated synchronously across three Azure availability zones in the primary region.LRS is the lowest cost redundancy option and offers the least durability compared to the other redundancy models. Locally redundant storage (LRS): data is replicated three times within a single data center in the primary region.The user may choose a specific region for creating a resource. These datacenters in a specific geographic region are grouped together to form a Azure Region. Azure operates in multiple datacenters around the world. I will discuss the different redundancy models, but before that I will explain about Azure regions. So, the appropriate redundancy model should be selected based on the nature and requirement of the data stored. When the availability increases, the cost also increases. There are four different redundancy models. Azure portal and Azure Storage Explorer offer easy and convenient visual solution for working on the data.ĭata redundancy helps to maintain high availability and durability of the stored data in case of any type of failures and outage. Accessible: Data in Azure Storage is accessible from anywhere in the world over HTTP or HTTPS if adequate permission is given.Hardware maintenance, updates and critical issues are managed by Azure itself. Managed: The user needs to manage only the data.So, a huge increase in data volume can be managed without performance impact. Scalable: Azure Storage is designed for massive scalability.No unauthorized user or application may ever access any data in Storage. Secure: Data is secure due to the encryption policies and the strict access control methods.Data redundancy helps to ensure durability and high availability of data in case of any unexpected outage or natural disaster in a region of the World. Durable and highly available: There is a provision to replicate the data in the region where the service is created (primary region) and in other regions (secondary region) as well.The different features of Azure Storage are detailed below: I will go through the step-by-step process of creating an Azure storage service for Blobs. I will discuss the different features, redundancy, and types of Azure Storage. Core storage services offer object store for data objects, disk storage for Azure virtual machines (VMs), a file system service for the cloud, a messaging store for reliable messaging, and a NoSQL store. Data in the Azure storage account is durable and highly available, secure, and massively scalable. The storage account provides a unique namespace for different types of Azure storage data accessible from anywhere in the world over HTTP or HTTPS. Azure Storage is the service for storing different types of data.
