 Wrap Your App
Subject: Wrap, but verify

Actually, I consider XML app deployment in my article "Building C++/XML/PL-SQL Shells", it was submitted to CUJ recently.


On packaging. Using zip archives looks pretty obvious for me.


On resource management. There is an important distinction here - between ready binaries deployment and complete deployment with source code.


Binaries deployment can be made mostly automatic. More exactly, we post app files to a given site automatically by FTP, then certain configuration adjustments will be needed. For example, proper environment variables will be set, Unix cron script prepared, etc. Here XML is a good way to specify system configuration settings.


However, main part of deployment is testing!
There is some discussion on representing test cases in XML and C++ source code in "Building ... Shells". Basically, we introduce testing methods in XML app, they can be enabled whenever necessary.


Take system configuration changes (why not take them as deployment from old platform to new one?). Now we can ping testing methods remotely and check that our app is still online.
