[OpenDroneMap-users] Cloud Processing (Stephen Mather)

One neat trick on Amazon EC2 is to use the Spot Instances - you can get 
the much more powerful r3.8xlarge instance type for about $0.25 / hr. 
That's 32 cores and 244GB of RAM! I didn't specifically time it, but if 
memory serves that chewed through the Langley dataset in about an hour 
end to end.

Just make sure that you request the spot instance in an availability 
zone that hasn't had price spikes in the past ~24 hours, and that you 
set the Max Price well above any spikes so your server doesn't get 
automatically shutdown based on price:
