If you're just running a small business with a local SQL Server, this news is probably not for you.

I told my TechNews aggregator to keep an eye out for anything newsworthy or interesting related to Microsoft Access, SQL Server, and the technologies surrounding them. This one technically qualifies, but it's probably massive overkill for 99% of the people reading this site.

Azure Local Disconnected Operations is not a replacement for installing SQL Server on a computer in your office. If you've got Windows Server running SQL Server, with a few Access databases connecting to it from computers around your office, you've already got a perfectly normal local SQL Server setup. You don't need any of this.

What Microsoft is talking about here is essentially bringing a chunk of the Azure cloud infrastructure into your own data center. Instead of simply running SQL Server locally, an organization can run virtual machines, containers, applications, and other services locally while managing them using many of the same concepts and tools that Microsoft uses in Azure.

The "Disconnected" part is what makes this particularly interesting. It's designed for organizations that need this infrastructure to continue operating without a connection to Microsoft's public Azure cloud. That can include highly regulated businesses, government and defense installations, manufacturing facilities, remote locations, or environments that may even be intentionally isolated from the Internet.

Think of the difference this way:

A local SQL Server installation says, "I want my database running on a server in my building."

Azure Local says, "I want Azure-style cloud infrastructure running on servers in my building."

Azure Local Disconnected says, "I want Azure-style cloud infrastructure running in my building, and I need it to keep working even if Microsoft's Azure cloud is completely unavailable or I'm intentionally disconnected from it."

That's a very different problem from what most small businesses face. If you've got 5, 10, 20, or even 100 users running an Access front end connected to SQL Server on your local network, this isn't something you need to start learning or deploying because Microsoft announced it.

It is newsworthy, however, because it shows where Microsoft is taking Azure and hybrid infrastructure. Azure is increasingly not just "Microsoft's computers somewhere on the Internet." Microsoft is making more of the Azure management model available to organizations that need to keep their computing infrastructure physically under their own control, including environments that can't depend on a continuous connection to Microsoft's cloud.

So this is interesting technology, and it's definitely related to the larger SQL Server/Azure ecosystem that I keep an eye on. But unless your "server room" requires security clearances, multiple racks of hardware, or someone walking around with a clipboard worrying about an air gap, you can probably file this one under "cool to know about" and continue happily running your local SQL Server. :)
