Azure Databases Fundamentals

This article provides a foundational understanding of the database services available on Microsoft Azure. Azure offers a comprehensive suite of managed database services designed to meet a wide range of application needs, from relational to NoSQL, and from mission-critical to development and testing scenarios.

Why Azure Databases?

Migrating or building applications on Azure provides several advantages for database management:

Managed Services: Azure handles most of the database administration tasks, such as patching, backups, and high availability, freeing up your team to focus on application development.
Scalability: Easily scale your database resources up or down to meet changing demands without significant downtime.
Global Reach: Deploy your databases in data centers around the world to ensure low latency and high availability for your users.
Security: Leverage Azure's robust security features, including encryption at rest and in transit, network security, and identity management.
Cost-Effectiveness: Pay only for what you use with flexible pricing models.

Key Azure Database Services
