how expose c++ program web service? or better idea invoke c++ java , expose resultant java web service. in case, c++ program should not undergo changes. interestingly, webservices work on http protocol, means can't "host" webservice written in c++ without having http server. since each web server have it's own mechanism of writing "hooks" or extensions, next obvious question web server chose. let's want iis on windows. it's possible use isapi extensions; need know how write one, complies web services standards. or, alternatively, it's better learn how in c++ visual studio, have lots of built-in stuff started . in short, there no "standard" way of exposing web service in c++ , have "platform" specific. windows iis has 1 way of doing it. apache axis c++ has another.

i'm starting migrate few applications amazon web services. applications python/django apps, running on mysql. i plan on using ec2 , ebs starters. i'm looking few things: a step-by-step tutorial explaining how deploy django on aws. i've looked around, tutorials 2 years ago, i'm worried they're outdated. i'm trying understand, ami should start? know there's bitnami ami comes preconfigured django goodiness, i've seen lot of other sources should start basic (clean) linux box , install yourself. why? are there other important things should thinking about? have little sysadmining experience (the apps on webfaction), i'm not sure should thinking about. a few points: i plan on running several applications on same ec2 instance, assume that's possible? i'm using virtualenv separate between various apps right now, assume can continue doing same on ec2 instance? thanks! there nothing "special" ec2 here. provides
