This is a survey of how people develop and deploy Perl web applications using PSGI. Collected results will be published and discussed in my upcoming talks at YAPC::NA and OSCON 2011.
One of the fun things about MetaCPAN is that we've split the project into two main parts: an API and a front end. What this means is that if you want to start pushing your code into http://beta.metacpan.org, you don't need to run a local copy of the API. You can just git clone the front end, install your dependencies and be on your way.

DotCloud is a second generation Platform-as-a-service provider with multiple languages and databases support. DotCloud recently shipped Perl stack with PSGI web application support. Tatsuhiko Miyagawa, who works for the company as a software engineer, explains how to develop your PSGI based web applications and deploy it to DotCloud.
