First Application Deployment
December 15, 2010
This is the first test of application deployment.
From the “Launcher” you can open the “AppBrowser” window to see the source code for this app. It simply clears the desktop, changes the background color, and writes “Hello World!” in large letters.
Application source code is stored in a special database whose keys are the names of the applications.
So in this case the application is named “hello” and is stored in the database with the key “hello”. When a user enters “http://silversmalltalk.appspot.com/hello” in the URL line of the browser, the Smalltalk interpreter parses the URL line and then loads and executes (if possible) the corresponding code stored the application database.
Deployment is instant: as soon as the code is stored in the database, it can be invoked as an application.
And, of course, this is deployed on the Google’s massive server infrastructure. It should work for thousands (or millions) of users.
