Thanks Vijay,

I am looking for how jobs are processed in cloudstack, let say for e.g. if I want to create a new VM, how this job is handled.

Thanks,

Hi Faisal,

Are you referring to the API dispatcher in cloudstack? If so, there are two starting points - one for servlet requests received over 8080, and the other for the integration port (8096 by default). The former starts with handle() in ApiServer.java. The latter starts with doGet() and doPost() routines in ApiServlet.java. 

Regards,
Vijay

API job dispatch and internal job execution are managed through Async Job
facility inside CloudStack. You can look at
ApiServer.java/ApiDispather.java/AsyncJobManagerImpl.java in source code
to get more details.

I'm currently working on improving VM state sync, HA and job management as
a whole as an enhancement feature, the work includes job scheduling, job
serialization, job monitoring, job concurrency control and a message bus
for job event notification, I will write down more details once I've got
time and notify the community accordingly
