RA-GRS data will be stored just like GRS, except that you get read-only access to the secondary region. In case of primary region failure, the secondary region is used as part of a fail-over mechanism. For GRS, six copies of data are stored across two regions, with three copies in a so-called primary region, and the rest in a secondary region, usually geographically distant from your primary region. Obviously, this will achieve greater durability than LRS.

With ZRS, three copies of your data will be stored in multiple facilities of two or three regions. Using LRS, three copies of all data are maintained in a single facility within a single region. There are four ways you can make sure data is stored redundantly: Locally Redundant Storage (LRS), Zone-Redundant Storage (ZNS), Geo-redundant Storage (GRS), and Read Access Geo-redundant Storage (RA-GRS). These features apply to all Azure Storage offerings: DurabilityĪzure Storage data is replicated multiple times across regions. In this article, we’ll explore Azure Storage’s benefits and features, the services/solutions it offers, and more. NET, Ruby, and Java for REST, and access from multiple Windows and Linux operating systems. For developers, Azure storage supports a variety of clients, such as. Under the hood, it comes with Microsoft’s guaranteed, massively scalable, highly available, robust and economical architecture. It uses a pay-as-you-go service model that will fit your business whether you’re storing only a few hundred GBs or trillions of objects. “Azure Storage is a cloud storage solution for modern data storage scenarios”Īs reported in the Microsoft Azure documentation.Īzure Storage capacity is virtually limitless. But Microsoft certainly hasn’t been quietly watching from the sidelines and Azure Storage has become a real player in the Cloud Storage game. Both AWS and Azure storage options are constantly improving, with AWS’s S3 and Glacier emerging as mature and reliable platforms. Services are becoming easier to use and more robust, scalable, and available.

The competition for customers among cloud vendors is driving a great deal of innovation.
