The most simple way to try Jet Admin and deploy it to free Heroku cloud platform with a few clicks. It will require you to allow access to your database from external network.
Any of the following SQL Databases:
Microsoft SQL Server
SQL database installed on host with external IP and opened port
Create application on Heroku (need to create account if you don't have)
You will be asked to specify application name and database settings
Register your project by opening in your browser: http://APP_NAME.herokuapp.com/api/register/ where APP_NAME is your Heroku application name. Initial Heroku is rather slow, it may take up to 30s to open page for the first time.
After registering your project you will be redirected to your project and can start working with Jet
