Hey Paul Thanks for the response. I've been reading a bunch of different tutorials and they all indicate what you have mentioned, which is that Amazon is not an ideal environment for running tile server- like workloads.
The challenge I've run into is that I have a requirement to set up a server like that; I don't have access to lots of capex to build a purpose-built server with, and I don't have a data center to run it in. Later, if I can get through a proof of concept stage, that may all come, but for now I need a lower cost and immediately available prototyping environment, and my options seem limited to public clouds like AMZ, Azure, Heroku, and similiar offerings. I understand the performance will be problematic, but I see that essentially as getting what I am able to pay for at this stage of my project. I'd be interested in your thoughts on two things: a) given the constraints I have, is there a better 'pay as you go' prototyping environment you are aware of that I could leverage? b) either for that environment, or for AMZ if that is no better or worse than any other available option, how would you set up a prototyping environment capable of delivering query results against a world database and serving tiles accordingly? I'm sure there are a lot of people like me that need low cost prototyping environments; rather than saying 'Amazon is inappropriate', perhaps we need to collectively develop a guide that says 'here is how you configure one'. I'm happy to help with that by documenting my own experience if that is useful. The alternative seems to be a future filled with admonishment and that seems like it would be less fun for all concerned. interested in your thoughts... _________________________________________ malcolm stanley google.voice: 215.821.6252 Cell: 267.251.9479 <------------- new email: [email protected] twitter / linkedin: amstanley Read my blog at http://soaringhorse.blogspot.com _________________________________________ On Fri, Jun 21, 2013 at 7:31 PM, Paul Norman <[email protected]> wrote: > Amazon EBS is extremely slow.
