SFTP for Blob Storage
SFTP for Blob Storage is the storage-account feature that exposes blob containers to SFTP clients after hierarchical namespace is enabled. Administrators configure local users, authentication methods, home directories, and permission scopes so external or internal clients can transfer files without custom SFTP infrastructure.

NFS 3.0 for Blob Storage
NFS 3.0 for Blob Storage means an Azure Blob Storage protocol option that lets Linux clients mount blob containers through NFS version 3. You see it when teams connect analytics jobs, HPC workloads, migration tools, or Linux applications that expect mounted file paths. Think of it as a storage protocol choice with account, namespace, and network requirements. It matters because the setting changes how teams design, secure, operate, and troubleshoot the workload. Before changing it in production, know the owner, dependency, evidence, expected result, and rollback path.

Primary storage region
The primary storage region is the home region for an Azure Storage account. When an application writes blobs, files, queues, or tables under normal conditions, it writes to the primary region. Microsoft Learn anchors this term in Data redundancy - Azure Storage, but this field-manual definition is intentionally wider than an older short glossary entry because the page must teach what to inspect, what can break, who owns the decision, and which evidence proves the Azure environment is behaving as intended. In field use, start with the technical boundary: Technically.

General-purpose v2 storage account
General-purpose v2 storage account is an Azure Storage account resource using the StorageV2 kind to host common storage services under one managed namespace. Teams use it to provide durable storage for applications while centralizing endpoints, redundancy, encryption, lifecycle management, networking, monitoring, and access control. In daily Azure work, it appears when engineers provision blob containers, file shares, queues, tables, static websites, backups, application artifacts, or Data Lake Gen2-enabled storage in a landing zone. It is not a specific blob container, an unlimited performance guarantee, an identity provider, or a safe design unless access, networking, and data protection are configured.

Infrastructure encryption for storage
Infrastructure encryption for storage controls how Azure Storage applies optional double encryption to blobs, files, queues, or tables depending on account and scope configuration. Teams see it in storage account creation, encryption blade. It is not blob immutability, soft delete, encryption in transit, customer-managed key rotation, or disabling shared key authorization; confusing them can create storage accounts that cannot meet compliance, rebuild-only remediation. Use the term when reviewing access, monitoring, cost, recovery, or performance. It keeps architects, operators, security reviewers, and support teams focused on the same setting, resource, or behavior.

Geo-redundant storage
Geo-redundant storage is an Azure Storage redundancy option that protects data by keeping primary-region replicas and asynchronously copying that data to a paired secondary region. Teams use it to reduce the chance that a regional outage destroys blob, file, queue, table, or Data Lake data that must survive a disaster. In daily Azure work, it shows up when engineers choose a storage account replication SKU, review disaster recovery requirements, compare GRS with RA-GRS or GZRS, or investigate why secondary-region reads are unavailable.

In daily Azure work, it shows up when engineers select Standard_GZRS or Standard_RAGZRS, compare ZRS with GRS, approve resilient storage standards, or investigate why an account is more expensive than LRS.

Table Storage
Table Storage is Azure Storage for simple structured NoSQL records. You create tables, store entities, and identify each entity with a PartitionKey and RowKey. It is useful when the data is large, sparse, inexpensive to keep, and usually accessed by known keys. It is not a relational database, search engine, or analytics warehouse. The best fit is operational data that can be denormalized, read directly, updated independently, and kept cheap without requiring joins, stored procedures, or secondary indexes.
