Azure DP-900 Short Notes: Explore provisioning and deploying relational database services in Azure

👉Learn Module: Explore provisioning and deploying relational database services in Azure

👉Provisioning is the act of running series of tasks that a service provider, such as Azure SQL Database, performs to create and configure a service.

👉A user is only able to define parameters that determine the size of the resources required.

👉The inner tasks done to provision a service are hidden from the end user.

👉several tools you can use to provision services.

1. The Azure portal
2. The Azure command-line interface (CLI)
3. Azure PowerShell
4. Azure Resource Manager templates

👉Pricing tiers of three relation DB services

1. Basic - workloads that require light compute and I/O performance.
2. General Purpose - business workloads that require balanced compute and memory with scalable I/O throughput.
3. Memory Optimized - high-performance database workloads that require in-memory performance for faster transaction processing and higher concurrency.

Describe configuring relational data services

• Configure connectivity to virtual networks and on-premises computers

  👉To connect to provisioned DB

  1.configure Firewalls and virtual networks page.
  2.Select networks.
  3.Three further sections will appear, labeled Virtual network, Firewall, and Exceptions.

  👉Azure SQL Database communicates over port 1433.

  👉A firewall rule of 0.0.0.0 enables all Azure services to pass through the server-level firewall rule.

• Configure connectivity from private endpoints.

  👉Private endpoint is a Network interface that connects you privately and securely to a service powered by Azure Private Link.

• Configure authentication

  👉Azure Active Directory(AD) to manage database user identities.

  👉Who can access the database?

• Configure access control

  👉Azure role-based access control (Azure RBAC) helps you manage who has access to Azure resources, and what they can do with access.

  👉RBAC through role assignment consisting of three elements

  1.A security principal
  2.A role definition
  3.A scope

• Configure advanced data security

👉Apart from Authentication and Authorization, implements threat protection and assessment.
