The VPS needs not be fast, unless you do training runs and optimizations on the VPS. Amazon also offers 1 year free VPS, and I can confirm that several Zorro instances run fine on the minimum version of the Amazon EC2 VPS.
Same here, i can confirm, i've had 2 instances running for over 1 week 24/7 and with no problems.
I think it could manage 1 more instance, so all in all it's great.
You can even run backtest on the minimum version, and it seems ok. even though the spec isn't very high..
I must say that the VPS has been the perfect answer for running Zorro. I was nearly going to buy a new computer a month ago for running/demo testing Zorro live 24/7 so many thanks for refreshing my memory as this is the most efficient, reliable and useful way to run Zorro live imo.
There are tons of VPS cluster/cloud services available i think you can even hire 20GHZ with 100GB RAM, SSD etc even on an hourly basis from some special providers.
Interesting and very useful for sure.
