Deploying Rails: Automate, Deploy, Scale, Maintain, and Sleep at Night (The Facets of Ruby)

Buy
Ruby on Rails has taken the web application development world by storm. Those of us who have been writing web apps for a few years remember the good ol’ days when the leading contenders for web programming languages were PHP and Java, with Perl, Smalltalk, and even C++ as fringe choices. Either PHP or Java could get the job done, but millions of lines of legacy code attest to the difficulty of using either of those languages to deliver solid web applications that are easy to evolve.

But Ruby on Rails changed all that. Now thousands of developers around the world are writing and delivering high-quality web applications on a regular basis. Lots of people are programming in Ruby. And there are plenty of books, screencasts, and tutorials for almost every aspect of bringing a Rails application into being.

We say “almost every aspect” because there’s one crucial area in which Rails applications are not necessarily a joy; that area is deployment. The most elegant Rails application can be crippled by runtime environment issues that make adding new servers an adventure, unexpected downtime a regularity, scaling a difficult task, and frustration a constant. Good tools do exist for deploying, running, monitoring, and measuring Rails applications, but pulling them together into a coherent whole is no small effort.

In a sense, we as Rails developers are spoiled. Since Rails has such excellent conventions and practices, we expect deploying and running a Rails application to be a similarly smooth and easy path. And while there are a few standard components for which most Rails developers will reach when rolling out a new application, there are still plenty of choices to make and decisions that can affect an application’s stability.

At the time this book was first
published, in 1979, it was a well-known rule of thumb that in a typical
programming project approximately 50 percent of the elapsed
time and more than 50 percent of the total cost were expended in
testing the program or system being developed.

Today, a quarter of the century later, the

Holub on Patterns: Learning Design Patterns by Looking at Code
Holub on Patterns: Learning Design Patterns by Looking at Code

Most programmers learn by looking at computer programs. This book teaches you design patterns in exactly this way: by looking at computer programs and analyzing them in terms of the patterns that they use. Consequently, you learn how the patterns actually occur in the real world, and how to apply the patterns to solve real problems. This book...
