Crudely:

       Managed: .NET/Java
   Unmanaged: C/C++

When you think of "managed" code, think "garbage collector".

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

I don't recall anyone ever actually mentioning the term "managed" when speaking about Java, but you can think of Java as such. As I said previously, the term "managed" refers to the fact that you have a garbage collector managing the deletion of dynamic memory for you. In a C/C++ environment, you must take care to delete any dynamic memory you allocate.

If .net is not installed then a managed application will not run.  Unmanaged has no requirement for .net runtimes to be installed.
