Did you know that Azure SQL Database was one of the first cloud database services offered by a major vendor? Launched in 2010, it predates many popular cloud services we use today. This early adoption by Microsoft positioned Azure SQL Database as a leader in cloud-based database solutions, paving the way for its current widespread adoption. While the delivery method has shifted to the cloud, Azure SQL Database remains built on the trusted SQL Server database engine, providing a familiar development experience for existing SQL users.

2) Globally Distributed for Peak Performance

Unlike traditional on-premises databases, Azure SQL Database boasts a globally distributed architecture. Microsoft operates a vast network of data centers strategically located around the world. This allows you to choose the geographic region closest to your users, minimizing latency and ensuring optimal performance for your applications. This global reach also enhances disaster recovery capabilities, as your data can be easily replicated to another region in case of unforeseen circumstances.
