Different ways to access Storage Account, Access Tiers, Redundency Level 🧊
What are the different ways to access the Storage Account?
Access Keys 🗝️ - These are like passwords. The problem with access keys is that it will give the full control of the storage account. (Hence not recommended)
SAS Token 🔐 - This will only provide the relevant permission that is required. (read-only, write etc)
What are the different types of access tires? ⌨️
Hot - This is for more frequent data access. Access time of data is very fast but the cost of accessing data is high.
Cold - This is for less frequent data access. The access time of data is less as compared to the Hot access tier and the cost of accessing data is also less.
Archive - This is used to keep old data. The access time of data is very high.
What are the different types of redundancy levels? #️⃣
Locally redundant storage (LRS) copies your data synchronously three times within a single physical location in the primary region. LRS is the least expensive replication option, but isn't recommended for applications requiring high availability or durability.
Zone-redundant storage (ZRS) copies your data synchronously across three Azure availability zones in the primary region. For applications requiring high availability, Microsoft recommends using ZRS in the primary region and also replicating it to a secondary region.
Geo-redundant storage (GRS) copies your data synchronously three times within a single physical location in the primary region using LRS. It then copies your data asynchronously to a single physical location in the secondary region. Within the secondary region, your data is copied synchronously three times using LRS.
Geo-zone-redundant storage (GZRS) copies your data synchronously across three Azure availability zones in the primary region using ZRS. It then copies your data asynchronously to a single physical location in the secondary region. Within the secondary region, your data is copied synchronously three times using LRS.
