Comments on: "Deployability" http://www.siberian.org/2009/06/26/deployability/ Just another WordPress weblog Mon, 30 Aug 2010 02:22:31 +0000 http://wordpress.org/?v=2.9.2 hourly 1 By: john http://www.siberian.org/2009/06/26/deployability/comment-page-1/#comment-20 john Tue, 07 Jul 2009 23:29:59 +0000 http://www.siberian.org/?p=42#comment-20 I have not found real evidence for the claims of exponential growth but there is no arguing that CPAN continues to be a vibrant community. My overall point RE: CPAN was more about 'growing in a useful way' and 'duplication of core features that live in other languages'. For example. the apache commons project is ~30 modules that contain a vast amount of functionality that would probably take many more CPAN packages to duplicate. In this light I think its very true that quantity is not a good indication of usefulness. CPAN is very useful though. I use it often, but CPAN is not great for deployability (in general). Projects like PAR (awesome btw, thanks for the pointer) directly points to CPANs deployability issue.

I just don't think its super deployable. That said, there is a huge tradeoff for deployability that I did not mention which is configurability. For example, in my Java projects I use maven. I type 'mvn package', I get war file, I drop it in a directory on my app server and its live almost immediately with all dependencies localized. Thats great for deployability but man it HURT to get the configuration right in that context. So to be fair, in many cases, the burden may be somewhat the same.

Some of the modules that do not update just do not need updates, some are deprecated. As for deployments, good modules are local::lib and PAR.
