Introduction to Azure SQL and Free Account Creation ☁️

• Azure SQL Overview:
  • Azure SQL is a family of managed, secure, and intelligent SQL cloud database services built on the SQL Server engine. ☁️
  • It offers various deployment options, including single databases, elastic pools, and managed instances, catering to diverse workload needs.
  • It removes the burden of infrastructure management, allowing you to focus on application development. 🚀
• Free Account Creation:
  • To get started, you can create a free Azure account. This provides access to a range of Azure services, including limited free usage of Azure SQL Database.
  • Visit the Azure website, sign up, and follow the prompts. You’ll need a Microsoft account and a valid payment method (for identity verification, not immediate charges).
  • Microsoft Learn also offers sandboxes that can be used to experiment with Azure resources without a credit card.

Detailed Content Additions:

1. Infrastructure as a Service (IaaS): 🖥️
   • IaaS provides virtualized computing resources over the internet. You manage the OS, middleware, and applications, while the provider manages the underlying infrastructure.
   • In the context of SQL, this would be a SQL Server installed on an Azure Virtual Machine.
2. Platform as a Service (PaaS): ☁️
   • PaaS offers a platform for developing, running, and managing applications without managing the underlying infrastructure. The provider handles OS, servers, and storage.
   • Azure SQL Database and Azure SQL Managed Instance are PaaS offerings.
3. Software as a Service (SaaS): 💻
   • SaaS delivers software applications over the internet, typically on a subscription basis. You access the application through a web browser or API.
   • While Azure SQL itself isn’t SaaS, applications that use Azure SQL can be delivered as SaaS.
4. Single Database: одиночная база данных
   • A single database is a fully managed, isolated database in Azure SQL. It’s suitable for applications with predictable resource needs.
   • It is provisioned with a set amount of resources.
5. Security (Logins, Users, Roles): 🔒
   • Azure SQL uses SQL authentication and Azure Active Directory (Azure AD) authentication.
   • Logins are server-level principals, users are database-level principals, and roles define permissions.
   • Proper role-based access control is very important.
6. Backup Retention: 🔄
   • Azure SQL automatically creates backups. You can configure short-term backup retention (up to 35 days) and long-term backup retention (up to 10 years).
   • Retention policies can be modified.
7. Restore Databases from Backups: ⏪
   • You can restore databases to a point-in-time within the retention period using the Azure portal, Azure CLI, or PowerShell.
8. Restore Databases from Deleted Databases: 🗑️🔄
   • Deleted databases can be restored if they are within the retention period.
   • This is done via the Azure Portal or PowerShell.
9. Long-Term Backups: 🗄️
   • Long-term backups are stored in Azure Storage and can be used for compliance or archival purposes.
   • They are configured with weekly, monthly, and yearly retention policies.
10. Refresh Non-Production Environments: 🔄
    • You can refresh non-production environments by restoring production backups or using database copies.
    • This is important for testing.
