To begin the final article of this series, take a moment to stand on the summit of Cairngorm and look down at how far you have climbed.

With a deeper understanding of Cairngorm, you now have the knowledge, tools, and expertise to be able to scale any complex rich Internet application, applying the lessons you have learned to tackle any application development project confidently, no matter how steep the problem may first appear.

By applying these lessons, you can consistently, effectively, and rapidly accomplish the design, development, and delivery of rich Internet applications knowing that the methods you use have been proven effective on numerous challenges as complex and critical as your own.

Let's consolidate this understanding with a quick review of the different patterns in Cairngorm and how they work together. In this article, we will review the essential infrastructure that you must have in place to efficiently deliver feature after feature into your application.

In addition, we'll show you how to complete a new development task in the Cairngorm Store. You can use the exercise to confirm that you are now ready to develop your own applications with Cairngorm by correctly applying the same best practices that so many other Flex developers use with success.

Requirements

In order to make the most of this series, you need the following software and files:
