Is there anyone out there running p2pool on Amazon AWS for themselves and a few friends? How is performance/efficiency? What instance size do you use and what is the monthly cost? I was starting to test this out on the free tier as a proof-of-concept, but the free tier can't even keep bitcoind up with the memory usage.
Yeah I have done it with
Memory optimized m2.xlarge 64-bit 2 6.5 17.1 1 x 420 - Moderate
using 10gig as a ram drive for bitcoind.
But it was getting close to/was using all the memory running two bitcoinds.
So was contemplating Memory optimized m2.2xlarge 64-bit 4 13 34.2 1 x 850
If you dont need rock solid uptime, you can do it on the cheap using spot instances using your own ami and a ebi volume for persistent data for p2pool and first bitcoind data.
Without volume charge your looking at around $25 to $30 for the 17gig memory one and double that for the 34gig memory one a month for usa. Other pricing areas you'll have to check.
With the second bitcoind in ram drive the getwork latencies were pretty low and was about 115% efficiency.
Was getting jumps now and then but, might have been the instance running out of memory, didnt look into it much more.
