Azure SQL Database was used internally solely for any new development or when extra capacity on an ad-hoc basis was necessary. Azure SQL Database was used across several departments.
SQL Server, as a mature and well known product that is around for so long makes Azure SQL Database a natural successor to it, which delivers on the same promises.
Users will find their familiar tools working seamlessly, any existing application would sustain likely a minor tweak or a mere configuration change to begin its Cloud journey. A migration off an on-premises SQL Server of almost effortless even from outdated versions.
Of course, with the Cloud the scalability becomes second nature and the server layer becomes transparent.
There are many options available how a client can securely access the data and the integration with Active Directory is supported.
The CAPEX to OPEX brings with it predictable spending, flexibility.
On the technology side, even though there are a couple of inconsistencies with the traditional SQL Server a business would find numerous benefits in Azure SQL Database as the ability to leverage the vast Microsoft Azure ecosystem and tools, reduced patching and version upgrades.
Overall, in my view, the Azure SQL Database is poised to constantly receive significant enhancements as Microsoft remains committed to growing its feature set.
