Terms in this definition
- Storage account
The top-level resource in Azure Storage, giving a unique namespace for table, queue, file and blob data. Location, performance and kind are set when it is created and cannot change.
- Premium SSD
Managed disk type on solid-state storage aimed at production and IO-heavy work, such as SQL Server data and log files. For example, a P50 gives 7,500 IOPS and a P60 gives 16,000.
- Dedicated
Running Azure Functions on an App Service plan, which removes the execution time limit and offers VNet integration on Basic and higher tiers.
- Azure Files
Azure's managed file shares over SMB or NFS. There is no Archive tier, and a single encryption key applies across the whole storage account.
- ZRS
Zone-redundant storage: data is written three times, each copy in a different availability zone of the same region, and nothing is replicated to a secondary region.
- LRS
Locally redundant storage, the lowest-cost redundancy option, keeps three copies of the data inside a single datacentre in the primary region.
- Redundancy
So that hardware failures, datacentre outages or a regional disaster cannot destroy data, Azure Storage keeps multiple copies: only in the primary region with LRS and ZRS, or in a secondary region as well with GRS and GZRS.
Related terms
- Azure SQL auditing
Azure SQL feature that sends audit logs to Event Hubs, a Log Analytics workspace (the only KQL-queryable option) or a storage account, which in the portal must be in the server's region and can't be premium FileStorage or legacy BlobStorage.
- Premium Azure Files
File shares on FileStorage accounts backed by SSDs, giving latency in single-digit milliseconds for transaction-heavy work. Only LRS and ZRS are offered, so geo-redundancy is unavailable.
- SMB Multichannel
A feature of Azure Files letting an SMB 3.1.1 client use multiple connections to one share to raise IOPS and throughput. Only premium shares (SSD, FileStorage) support it.
