its not just resource constrained environments, but use cases where the advantages of a c++ web app outweigh the disadvantages.
C++ web apps are fast. They are low memory usage (especially compared to solutions like java/RoR or PHP). They tend to use little cpu.
Ultimately, once a little ground work is done, you are still designing the interface in html, javascript and css, and have all the advantages and speed of development of that delivery method.
For some definition of the word, I believe that Facebook is effectively deploying a c++ web app as part of its solution at this point.
There are many use cases for which RoR or PHP is the better solution, but it turns out it is imply true that there are others for which a c++ web app is the better solution.
Go figure :)
- Skinney 13y agoSince any web-framework should be mostly IO-driven, the actual speed of the code matters very little as it will in most cases always be nothing compared to the actual IO-operation itself :/ In case you need certain code to run very fast, most people will write that in C/C++ and patch it into their solution, that's what we did in the Django-workshop I used to work in. I thought Facebook mostly used C++ for their PHP VM? Facebook itself is alot of PHP, they also use Cassandra (Java DB) for inbox messages I believe.
- pork 13y agoNo -- Facebook's PHP code is translated to C++ by HipHop and compiled into a monolithic binary, and Cassandra has largely been deprecated in favor of HBase.
- Skinney 13y agoFacebook is using HipHopVM, which is a JIT for PHP. HipHop is no longer a PHP -> C++ compiler. Didn't know they switched to HBase, it's still Java though.

- Skinney 13y agoThat note is from 2011. According to wikipedia: http://en.wikipedia.org/wiki/HipHop_for_PHP http://en.wikipedia.org/wiki/HipHop_for_PHP "in Q1 2013, the production version of facebook.com started running on HHVM, replacing HPHPc."
- bandushrew 13y agoohh, nice. I wonder how well silverstripe runs on it....
