As it's name implies, MSDE is designed as a desktop DB engine but not as a server application that can be run in a production environment.

Some limitations of MSDE as suggested by Microsoft: 16 database server instance on a single computer

It has a managed concurrency workload governor that limits up to five concurrent batch workloads for optimal performance.

If you have an application built around MSDE database on your machine and you want to use it in our system, you can easily migrate the application to our MS SQL hosting platform.
