Data is the lifeblood of businesses. Ensuring its availability & durability is vital. Let’s dive into Azure’s redundancy options and their significance.

🔄 Azure Storage replicates your data three times in the primary region with two options: Locally Redundant Storage (LRS) & Zone-Redundant Storage (ZRS). Ensuring high availability & durability.

📍 LRS replicates your data three times within a single physical location in the primary region. Cost-effective but not recommended for applications requiring high availability.

🌐 ZRS replicates data across three Azure availability zones within the primary region. Ideal for applications demanding high availability.

🌍 Geo-redundant storage (GRS) and Geo-zone-redundant storage (GZRS) are both Azure redundancy options that replicate data to a secondary region. However, their primary region data replication strategy differs.

🔀 GRS replicates your data three times within a single physical location in the primary region. Then, it asynchronously replicates the data to a single physical location in the secondary region.

⚡ GZRS, on the other hand, synchronously replicates your data across three Azure availability zones in the primary region. After that, it asynchronously replicates the data to a single physical…
