What is this?

Azure SQL Database is a managed SQL Server engine in Azure. You create a server + database, set firewall rules, and connect with a connection string.

Why should you care?

CloudVerse APIs need durable relational data — Azure SQL pairs naturally with EF Core.

See it live — copy this example

Use an Azure lab/free subscription. Prefer Azure CLI or Portal. Delete idle App Service plans, SQL DBs, and AKS clusters when practice is done.

az sql server create -g rg-cloudverse-dev -n sql-cloudverse-dev -l eastus -u sqladmin -p "ChangeMe#12345"
az sql db create -g rg-cloudverse-dev -s sql-cloudverse-dev -n cloudverse
# Allow Azure services / your IP in firewall before connecting

What happened?

Server is the logical admin endpoint.
Database is where tables live.
Firewall must allow your client.

Practice next

Create server + database.
Add your client IP firewall rule.
Connect from SSMS or Azure Data Studio.
Enable Microsoft Entra auth if your lab supports it.
Estimate DTU/vCore cost.

Remember

Azure SQL is managed SQL Server. Firewall + identity matter. Store secrets in Key Vault or App Settings.

Orders DB

API needs Orders table in the cloud.

Outcome: Connection works from your laptop and later from App Service.

What are pipeline templates and how are they used? Answer: Templates let you reuse pipeline steps across projects — great for standardization. Example: You can create a reusable file: 📄 .azure-pipelines/build-template.yml steps: - script: dotnet restore - script: dotnet build Then in your main pipeline: extends: template: .azure-pipelines/build-template.yml This keeps your YAML DRY (Don’t Repeat Yourself) and consistent.
