Interesting Jennifer.
Let’s skip that moment that RC did not have float license.
Use a Steam licence - that floats …

But can you roughly estimate how much will cost usage of cloud computing for project.
For example 1000images 24Mpx
If this is perfect dataset and not required any experiments with settings, in my PC with i7 and GTX960, 64Gb RAM whole process required about 12-24 hours of work.
It would depend a lot on which i7 - some here are using laptop i7 and other may be using overclocked K series.
but for comparison lets use my my dual xeon (each cpu is ~30% slower than a fast i7 because they only clock to 3ghz) with 8 real cores (8 virtual) which RC uses all 16cores pretty much 100% during image alignment. Doing the default “start” on a scene with ~600images (21mpx) takes about 25 minutes (board room interior, lots of alignment fails because everything is so repetitive). Meshing goes pretty quickly with 2xgtx1080.
On a smaller run, the model said 12 minutes for alignment and 8 for meshing.

Which instance suitable for such RC work ?
All i tried clouds estimate before was cost 3-5 times more in 1-2 years timeline comparing to just a good PC.
May be i wrong?
https://aws.amazon.com/ec2/instance-types/
if you are keeping costs down, have a look at https://aws.amazon.com/ec2/spot/bid-advisor/
for image load and doing control points, you might get away with a t1.micro ($0.02/hr) or use a m1.small ($0.09/hr)
For image alignment, maybe a c4.4xlarge (16 cores 122gb ram) for $1.50/hr but you can grab a c4.8xlarge(36 core, 60gb) for $3/hr
If you are in a rush, how about a x1.32xlarge (128 cores, 2tb ram) for $15.60/hr?
(these are defined duration prices, you can save ~50% if you can make the spot pricing work for you.)
When meshing, you probably want GPU, so you need to swap to a p2 or g2 instance (p2 for compute only, g2 if you want to spin your models around and have a look). These cost anywhere for $0.70 to $18/hr depending on how much GPU you want.
Keeping in mind these are billed by the minute - if you finish in 10 minutes, the expensive instances may end up costing less overall.
Just always always always remember to shut the instance down when you finish. Quite a few people have just logged off and leave the instance running (idle) and come back to find they had run up quite a large bill. (cheap per hour, but leave it running over a weekend still runs up a bill)
Hope this helps
