When using Apache Brooklyn (which calls down to jclouds), it failed to provision a VM in eu-west-2 - see https://issues.apache.org/jira/browse/BROOKLYN-412.

It chose m3.medium when given minRam=1000, but I believe that m3.medium is not available in that region.

When I supplied an explicit hardwareId and imageId, it provisioned the VM successfully.

Is it possible to retrieve the set of hardware types via an AWS api, rather than us hard-coding them in AWSEC2HardwareSupplier?

Unfortunately, AFAIK there is no such api method to get the hardware profiles. We studied time ago using some auto-generated json files we found, but the URLs were not stable and the contents not complete (they were pricing focused, not a real list of hardware profiles).
It is very inconvenient, but AFAIK there is no consistent way of getting them from the API or a public endpoint.

Hello Ignasi,
I have added code for this issue:
