Guess who switched to Heroku and Cloudflare on October 23 and got the performance optimization completed on October 24 (once all the DNS changes had quieted down)?  Folkerts Fotografie, that's who:-) Â
These numbers, as reported by Pingdom, are an almost unbelievable improvement. Â The performance over the previous app engine platform is really dramatic. Â To say that we are happy with the combo of Play Framework 2.x, Heroku and Cloudflare is quite the understatement.

FolkertsFotografie is online
To my surprise, my wife's web site on Google App Engine had a surprisingly bad uptime this month as measured by Pingdom (about 96% uptime). Â This helped to push me to actually get a site out on Heroku using the Play 2.0 framework. Â The result is Folkerts Fotografie.
To improve performance and security, the site is using CloudFlare and their content delivery network, cdnjs. One of the fun things about cdnjs is that they only have about 4 paragraphs of text and even so, their advice to use protocol relative URLs for resources taught me another useful trick.
We are also using Twitter Bootstrap 2.0 and Kickstrap to build the UI. My only gripe with Bootstrap is that you end up adding non-semantic CSS classes like 'span3'. Â LIke any big complex library , bootstrap has a learning curve. Â But with some help at stackoverflow, I was able to get past most of my issues.
From a coding standpoint, the site is basically built from Atom Feeds from Some Other Host's Content; news = Blogger posts and the home page and galleries are feeds from Picasa, at least for now. Â I have both client-side Ajax and a server-side web hook to get Blogger content; this was more to force me to use both techniques. Â Given how both Heroku and tumblr are on EC2, it may improve performance to use tumblr/imgur rather that Blogger/Picasa; its pretty hard to beat the latency of same datacenter.
In summary, I have learned a great deal about some of the new development tools and I am for the most part quite impressed. Â I suspect that I would have been better off with Liftweb, which is more stable and secure, but perhaps this will give me a chance to do an A/B comparison between these two Scala web frameworks. Â This is a simple site, but still enough to help me learn some new tools.
James Ward, of Heroku, gave this talk at Oracle OpenWorld 2012. Â He writes a new Scala application from scratch using IntelliJ.
Zilverblog has a series of five blogs by Erik Rosendaal that works through writing a blog engine that uses event sourcing. Â The first post was on the Fourth of July, and the final post was August 26. Â
Play! Authenticate Plugin
Play! Authenticate provides a plugin for OAuth2 and OpenID for developers of Play! Framework 2.0.  There is a demo app on heroku that allows for access to a restricted page, once you authenticate.  This is the work of Joscha Falco.

Play application on Heroku?
Being both cheap and curious, I'm looking for a way to host a simple Play application. Â Heroku has a bunch of great features and hosting for Play 2.0. Â I like PostgreSQL, Heroku has several hosted options including some that are free for the scale of use that I need. Â Heroku support SendGrid, an inexpensive way to send emails from an applications. Â Ivar Abrahamsen has rambled about getting this set up. Â For a proof of concept design, this is also free.
I'm looking to replace an existing small site, so I'll need to get redirects working. Â Play Actions support redirects.
I have a little Play app running and a domain name from GoDaddy. Â Now all I need to do is kick my wife off the computer for a while. Â Once that is done, I want to get CloudFlare setup to make the site safer and faster. Â This should be a fun test.

In this new posts series I’ll try to gather all steps of a spike I did building a prototype using scala and a graph database.Â

Play! Framework as the web framework, in its 2.0 version built from sources. Neo4J as the back end service for storing graph data. Scala for telling the computer what it should do...Â
