Introduction to Azure SQL Database
Welcome to the introductory tutorial for Azure SQL Database. This tutorial series will guide you through the fundamental concepts and practical steps involved in using Azure SQL Database, a fully managed cloud database service that handles most database management functions such as upgrading, patching, and backups without the need for user intervention.
Key Benefits
- High Availability and Durability: Built-in redundancy and automated backups ensure your data is safe and accessible.
- Scalability: Easily scale your database resources up or down as your needs change.
- Security: Comprehensive security features protect your sensitive data.
- Cost-Effectiveness: Pay only for the resources you consume with flexible pricing options.
- Managed Service: Reduce operational overhead as Microsoft handles patching, updates, and maintenance.
What is Azure SQL Database?
Azure SQL Database is a Platform as a Service (PaaS) offering from Microsoft Azure. It provides a relational database as a managed service, allowing developers to focus on application development rather than infrastructure management. It's built on the SQL Server engine and offers compatibility with existing SQL Server applications.
Key components and concepts include:
- Logical Server: A management construct for SQL databases, containing databases, logins, and other management objects.
- Database: The actual container for your data.
- Elastic Pools: A cost-effective solution for managing and scaling multiple databases with varying usage demands.
- DTUs (Database Transaction Units): A simple, bundled measure of compute, I/O, and memory resources.
- vCore: A more flexible model where you choose compute and storage resources independently.
Choosing the Right Model: DTU vs. vCore
The DTU model offers a simpler, bundled approach, suitable for predictable workloads. The vCore model provides more granular control over resources and is often more cost-effective for complex or variable workloads, allowing independent scaling of compute and storage.
