Azure SQL provides advanced levels of availability and reliability which SQL Server struggles to match. The first way Azure SQL accomplishes this is by replication. Automatically, Azure SQL replicates every database twice on two different nodes. By providing this level of replication and availability, your database will very scarcely experience downtime or data loss.
Conversely, SQL Server requires manually implementing database mirroring and failover clustering. This requires effort from IT teams that are already stretched thin and provides an opportunity for error that could prove disastrous.
Another way that Azure SQL enables better reliability is through continuity. It automatically backs up database and transaction logs so if there is any data loss or errors, your organization will be able to restore their database to the way it previously was. Azure SQL also prevents data loss through geo-redundancy, since Microsoft’s cloud is hosted in dispersed locations. This will keep your data safe from events like natural disasters which could destroy or temporarily take down your organization’s traditional data centers.
Azure SQL’s advanced continuity simplifies the back-up process and allows your IT team to restore its database at any point in time. This makes restoring data nearly stress-free. Through harnessing the power of replication and continuity, Azure SQL can allow your organization to fully rely on its databases.
