These are slides from my presentation to the Grails Cafe Centro meetup in San Francisco on Aug 16th 2011.
Most of the session was practical, so the slides are brief and are mostly useful for the links they contain.
The document discusses email event sinks and migrating an email server from Windows 2003 to 2008. It describes how email event sinks define how a server handles events like changing file extensions and parsing envelope headers. When testing a newly configured Windows 2008 server with an installed email event sink, the sink did not function properly and emails were not processed as expected. The document recommends rewriting the sink code or using an alternative like Postfix for its free cost and large community support. It also discusses the Lease Eagle website and improvements made to its design, including a centered layout, updated content and screenshots, and interactive elements.

So here we have our brand new app, but how about its deployment, autoscale, high availability and so on?
We're gonna take a journey from source code posted to GitHub to deployment in Google Cloud Platform which will be capable to take bazillion of requests.
Will make our own docker image and see how it is looks like in practice.
Will start our first kubernetes cluster and deploy our app.
Will have a sneak peak into autoscaler and high availability
Search facilities have become such a basic commodity in applications that it's almost taken for granted.
But bundled with a framework such as Grails, you the developer are faced with some limitations and extra concerns: how well is this library developed and backed? does the library fit the framework's paradigm and how good is the support for the tool within the framework itself?
This talk will provided an overview and comparison in search for a piece of the holy grail - a good search facility.
