Hi,
Assuming you mean Java Threads, I guess you are talking about being
able to execute arbitrary (classes that implement) Runnable in a JVM
in the cloud ?
A Thread & Runnable has no inherent comms for returning the results of
the execution from the cloud back to the device, your framework would
need to provide this - there is a multitude of options.
As far as -
* You don't get hard time limits on requests like you do with App
Engine
- I think you must still handle the 'turing halting problem' issue
where some code might have gone into an infinite loop and must be
stopped eventually, eg:
int a = 0; int b = 0; while( a == b ) { a++; b = a; }
so you would still need hard limits to interrupt this sort of code,
eventually anyway - but when ?
I would also be interested in what java api's would be available to
the thread when it is running in the cloud - all of the Android sdk or
j2se or j2ee, or some whitelist as per App Engine ??? I think there is
some issues that would make it difficult for you to provide the full
android sdk in the cloud, eg ndk integration and performance in
general - if you were for example, running instances of the Android
emulator in the cloud and using these as your vm / jvm 'cloud based
thread engine'.
Perhaps you can create a demo app and publish the code and performance
details.
