-----------------------------------
Thanks for the pointers. I would love an intro to Backtype because I know they've created a patch in the past for the Python contrib WHIRR-76. Maybe they are now interested in using / contributing to the Java version.

ah, yes. so in backtype, they always set spot price to current real price, so this doesn't happen [most of the time :)], and they always save money as you only pay the spot price, not the max value you put in.

---------------------------------
So it sounds like if the price isn't fulfilled it times out after 20 minutes (jclouds.compute.timeout.node-running). This is the thing I was missing.

Tom White commented on WHIRR-260:
---------------------------------
Should we put the cloud provider name into options that are only supported there? E.g. ec2_spot_price?
It would be better to push the spot price configuration into TemplateBuilderStrategy, but that would mean changing that class to return Template, not TemplateBuilder. Given that we just call build() on it anyway, perhaps that's OK.
What is the behaviour if the spot price can't be fulfilled? Does it time out? It would be nice to add a little documentation and/or links to any relevant EC2 docs.

Adrian Cole commented on WHIRR-260:
-----------------------------------
sorry. there is no guide outside the source code and amazon's documentation,
http://docs.amazonwebservices.com/AWSEC2/latest/APIReference/index.html?query-apis.html
I generally recommend looking at the test cases for usage example, or posting to the jclouds-dev google group, as I'm better at following-up there, and also others can benefit from the questions. The more interesting test case to view is SpotInstanceClientLiveTest, which uses the api directly and AWSEC2ComputeServiceLiveTest.testExtendedOptionsAndLogin() which uses the spot price option on the portable interface.
In the code, AWSEC2CreateNodesInGroupThenAddToSet actually manages creating the spot instance request. The way jclouds manages this is that it looks for both regular reservations and also spot requests when listing nodes. The convergence of these 2 is what you'll see in a listNodes command (AWSEC2ListNodesStrategy ex. does these multiple listings in parallel)
If there's an error on the parameters requesting nodes, you'll receive an HttpResponseException in the 400 range from ec2 itself. The other condition you should be aware of is when the spot request goes through, but perhaps takes longer to provision the nodes than the jclouds default timeout (jclouds.compute.timeout.node-running), something I've not seen happen.
I've added some of these notes here, and feel free to revise: http://code.google.com/p/jclouds/wiki/EC2
Backtype were the first users of the Spot Price feature, last year. I can connect you, if you want some behavioral experience with this in the wild. Cheers!

Soren Macbeth commented on WHIRR-260:
-------------------------------------
Hi Guys,
AWS was having issues last night filling spot requests, possibly related to the change in pricing by AZ rather then region (just speculation on my part), in an case, I tested the patch out while this was happening. Once the requests timed out, there was an issue where the previously unfilled spot requests weren't canceled, and entirely new set of requests were issued. This would be undesirable behaviour, so if possible whirr should catch the timeouts and clean up any outstanding open, but unfilled spot requests and cancel them.
FYI - We (Yieldbot) also use spot based instances for our production hadoop clusters. We use a custom forked version of the python contrib scripts + a patch for spot instances based on BackType's work. We also use the trick of setting our bid price above the actual reserved instance price, but this isn't 100% successful, price spikes can still take out some instances, or prevent requests being filled, but it works well most of the time.
