Instead of believing everything behind the corporate firewall is safe, the Zero Trust model assumes breach and verifies each request as though it originated from an uncontrolled network. Regardless of where the request originates or what resource it accesses, the Zero Trust model teaches us to "never trust, always verify." Some of these techniques may contribute to security, but the Zero Trust model is about verification and assuming that your systems have been breached. Refer to Microsoft Doc:

Premium storage using SSD (solid-state disks) and is optimized for high transaction rates and single-digit consistent storage latency. It is available in select regions, supports block blob storage only, supports high throughput block blobs, and only supports LRS and ZRS for redundancy. Refer to Microsoft Doc:

Gremlin API allows users to make graph queries and stores data as edges and vertices. Cassandra API stores data in column-oriented schema. Core (SQL) API stores data in document format. Table API stores data in key/value format. Refer to Microsoft Doc:

Indexes speed up the retrieval of rows by pre-sorting them in a manner that is fast to search. Too many indexes can make updating a database slower and less efficient, so there is a balance to make. Refer to Microsoft Doc:

Azure Storage always stores multiple copies of your data so that it is protected from planned and unplanned events, including transient hardware failures, network or power outages, and massive natural disasters. Redundancy ensures that your storage account meets its availability and durability targets even in the face of failures. 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 is not recommended for applications requiring high availability or durability. Refer to Microsoft Doc:

The standard tier of Azure File storage is based on the spinning magentic disks of a Hard Disk Drive (HDD), while the premium tier offers faster performance on Solid-State Drives (SSD) Refer to Microsoft Doc:

A stored procedure in SQL Server is a group of one or more Transact-SQL statements. They can accept input parameters, contain programming statements, they can call other stored procedures, and they can return a status code to indicate success or failure. Refer to Microsoft Doc:

Using a tool such as sqlcmd can allow you to run SQL commands from the command line. The others are generally Interactive Development Environments (IDEs) that using a user interface to run SQL queries. And Azure Cloud Shell gives you access to a shell, but you still need to use a command line tool like sqlcmd to run the query. Refer to Microsoft Doc:

Azure Active Directory (Azure AD) authentication is a mechanism for connecting to Azure SQL Database, Azure SQL Managed Instance, and Synapse SQL in Azure Synapse Analytics by using identities in Azure AD. With Azure AD authentication, you can centrally manage the identities of database users and other Microsoft services in one central location. Refer to Microsoft Doc:
