AWS ec2 instances to be charged by seconds from Oct 2nd

[ambirag]

This means the current logic of cost optimized termination has to be changed to immediately terminate nodes ( say 5mins idle time - or make it configurable) Source: https://aws.amazon.com/blogs/aws/new-per-second-billing-for-ec2-instances-and-ebs-volumes/

@ambirag I did see this announcement. I'm not sure what the best way is going to be, as we're going to want to balance cost vs time to spin up new resources.

@mhardin also this is applicable only to AWS linux boxes (not other flavours)

@ambirag @mhardin I was thinking about a 5 minute idle time, if no new tests are coming in during that time the instance will terminated. Also the possibility of setting this idle time via the property file would be nice. What do you guys think?

[mhardin]

@lenny1806 a 5 minute / configurable amount would be fine. Only problem is this is likely going to require a large refactor to accomplish this logic.

@mhardin Has this issues been given any more thought? I'm currently reviewing the project to possibly tie it into my test framework. Thanks

[mhardin]

@bloomm09 unfortunately no update on my end

[ambirag]

I have local changes which terminates nodes based on seconds, if you pass -D property name otherwise it will retain old behaviour

[ambirag]

actually you dont need this feature, once your automation execution is completed, you can simply call curl -X "DELETE" http://HUBIP:4444/grid/admin/AutomationTestRunServlet and it will simply terminate all the nodes @bloomm09

[mhardin]

@ambirag calling the delete endpoint only works if you have at most one test run against a hub. If you have multiple test runs against a single hub, I don't think this will work well.
