1. Perl Platform as a Service Shootout Mark Allen mrallen1@yahoo.com https://github.com/mrallen1 https://metacpan.org/author/MALLEN
2. "Platform as a Wha?" Coders don't have to be system administrators •  Deploy your code •  Magic happens •  Your application is live •  Web applications •  Now queue workers too
3. Platform as a service shootout Most PaaS providers support python, php, ruby or node.js "natively" A few support Perl deployments. How magical is Perl support?
4. Test application: geotz Given a JSON encoded list of IP addresses, return the UTC offset for each IP's timezone. Input: ["24.24.24.24"] Output: { "24.24.24.24" : { "country_name": "United States", "region_name": "New York", "city": "Buffalo", "time_zone": "America/New_York", "utc_offset": -14400 } }
5. Implementations Perl •  Dancer •  Mojolicious Python •  Flask Erlang •  Webmachine
6. Perl Dependencies Dancer • Try::Tiny • Regexp::Common • DateTime • DateTime::TimeZone • JSON • Geo::IP <= hard to automate
7. Perl Dependencies Mojolicious::Lite • Mojo::JSON • Try::Tiny • Regexp::Common • DateTime • DateTime::TimeZone • Geo::IP <= hard to automate
8. Python Dependencies • Flask (and Werkzeug, Jinja2) • PyTZ (core python tz support sucks) • pygeoip
9. Erlang Dependencies • webmachine • mochiweb • egeoip
10. Providers •  Heroku •  dotCloud •  Stackato (my 45 day trial ended) •  OpenShift (Red Hat) •  flexflux.com (closing) •  Juju (Ubuntu)
11. Evaluation Criteria •  Ease of deployment •  Performance? •  Cost? •  How "magical" Perl support is relative to other supported languages. (First class or hacked together?)
12. Evaluation Criteria •  Ease of deployment •  Performance? •  Cost? •  How "magical" Perl support is relative to other supported languages. (First class or hacked together?)
13. Findings • Getting PSGI compliant Perl web apps (with sensible dependencies) into PaaS environments is generally pain free. • But python is still less painful. • Erlang is a unicorn. (Some PaaS providers have alpha quality support.)
