[development] Scalability, Load Balancing, and High Availability - Possible SoC Proposal

[Scott Hadfield]

Hi All,

I've been thinking about a possible summer of code idea, but I'm not sure it
will fly so I wanted to get some feedback.

The basic idea is to look into solutions for running Drupal simultaneously
across multiple servers for the purposes of running extremely large/busy
sites, for load balancing on multiple servers (both database and web
servers), or just for high availability (if one server dies, another will
kick in). The project would consist of developing and documenting ways that
this can be accomplished and developing tools or other Drupal
patches/modules that are needed to accomplish the various tasks.

One of the main problems with this as a SoC proposal is that a large
majority of what needs to be done here is OS/web server/database server
specific. There would probably be a lot of Drupal specific stuff, but I'm
not sure exactly how much.

Even if this won't fly as a SoC project I am still be interested on working
on this. What's already been done in this area? Maybe some of this has
already been solved?

Thanks for any feedback,
Scott
