Mark Imbriaco, 37signals

Wed, 30 Jun 2010 14:58:00 -0700

We caught up with Mark Imbriaco, Operations Manager at 37signals at DevOpsDays. 37signals is the successful developer of project management and collaboration tools founded by David Heinemeier Hansson and Jason Fried, based in Chicago. In this interview with Mike Malloy, Mark shares some background on his role at 37signals managing the availability and performance of their popular suite of SaaS tools through a period of rapid growth over the past few years. Mark discusses how his team works with the development teams, their experience with cloud deployments, some of the challenges they have faced as well as a few lessons learned. We filmed this outside, so you will hear some wind noise and some chatter from the next picnic table over in the first five minutes, but the noise subsides after a few minutes. Thanks, Mark.

Yehuda Katz & Justin George Talk Rails 3

Tue, 08 Jun 2010 09:03:00 -0700

Yehuda Katz from the Rails core team and New Relic’s own Justin George talk about what’s new in Rails 3. They begin with an overview of current and planned performance improvements, then follow up with a discussion of how instrumentation–like that performed by New Relic’s RPM Ruby agent–is better enabled in the Rails 3 framework. Lastly, they touch on what users can expect as they make the change from Rails 2 to Rails 3.

State of the Stack: A Ruby on Rails Benchmarking Report - 25 May 2010

Tue, 25 May 2010 15:45:00 -0700

As of 24 May 2010

Because New Relic RPM is used by more than 4,000 organizations to manage their Ruby on Rails and Java applications in production, we have unique insight into how thousands of applications are deployed.

Since April, 2009, we have periodically published a summary of the most commonly used versions of Ruby, Rails and the various plugins and gems deployed for Ruby applications. This report enables you to compare your own deployed application stack with those used by other development teams. Are you behind the curve in Ruby? Are there some plugins or gems that your team may want to consider? Have you developed a gem and wonder how many apps use it in production? This is a good place to start that conversation.

Later this year we will publish benchmarks of the Java stacks our customers use.

Many of our customers have opted in to have their performance data shared with the Rails Core Team to aid in the team’s ongoing work on the platform. In addition to that data New Relic also aggregates information on the versions of OS, Ruby, and Rails used and the various plugins deployed.

In this report we list only the most commonly used Ruby and Rails versions and only the most commonly used plugins and gems because a complete list is too long to post here and is probably not all that useful.

The research is done by identifying the versions of deployed application stack components on more than 5,000 hosts monitored by New Relic. This report does not measure market share of any software. It is intended to provide Ruby on Rails developers with a means to compare their own deployment choices against the larger population of deployed production RoR apps.

Most Commonly Deployed Ruby Versions
(% of RPM Users)

Ruby 1.8.6 remains the most commonly used version, declining a bit from our last report in January. Version 1.8.7 continues to increase in popularity.

Most Commonly Deployed Rails Versions
(% of RPM Users)

With a surge, Rails 2.3.5 has become the most commonly used version growing from only 13% of deployments in January to 48% today. As expected all other versions have declined in use. It’s interesting to see that Rails 3.0 Betas 1, 2, and 3 are used on nearly 2% of hosts. Watch this number grow dramatically in the months ahead.

Most Commonly Used Gems
(% of RPM Users)

This is the list of the top 50 gems deployed. If a gem you are interested in is not listed, tweet @newrelic with the gem name and we can tweet the percent of use across our customer base. How to read our Gems chart: The number following the name of each gem represents the percent of hosts having this gem deployed.

Most Commonly Used Plugins
(% of RPM Users)

This is the list of the top 50 plugins deployed. If a plugin you are interested in is not listed, tweet @newrelic with the plugin name and we can tweet the percent of use across our customer base. How to read our plugin chart: The number following the name of each plugin represents the percent of hosts having this plugin deployed.

State of the Stack: A Ruby on Rails Benchmarking Report - 7 January 2010

Thu, 07 Jan 2010 09:49:00 -0800

As of 31 December 2009

Because New Relic RPM is used by more than 3,000 organizations to manage their Ruby on Rails and Java applications in production, we have unique insight into how thousands of applications are deployed.

Since April, 2009, we have periodically published a summary of the most commonly used versions of Ruby, Rails and the various plugins deployed for Ruby applications. This report enables you to compare your own deployed application stack with those used by other development teams. Are you behind the curve in Ruby? Are there some plugins that your team may want to consider? This is a good place to start that conversation. Later this year we will publish benchmarks of the Java stacks our customers use.

In this report we list only the most commonly used Ruby and Rails versions and only the most commonly used plugins because a complete list is too long to post here and is probably not all that useful. This report does not cover Gems.

And without further ado…

Most Commonly Deployed Ruby Versions
(% of RPM Users)

Ruby 1.8.6 remains the most widely deployed version. That said, 1.8.7 has seen a marked increase in usage since our last report in June, going from 5% to 30% in just a few months.

Most Commonly Deployed Rails Versions
(% of RPM Users)

2.3.2 remains widely deployed as we reported in June, though most of our customers are now using 2.3.4, which was released in early September 2009. A significant percentage are also using 2.3.5, released at the end of November.

Most Commonly Used Plugins
(% of RPM Users)

While the top five plugins remain unchanged since June, hoptoad_notifiier has replaced exception_notification as the most common plugin, with over 50% of our user base having deployed it.

How to read the Plugin data: Of all New Relic customers deployed into production, X% have this plugin installed in an application. This does not represent market share or total adoption within the Rails community. It represents the percent of New Relic customers who have the plugin deployed.

UPDATE: We are now capturing the Gems deployed by our customers as well. Here is a list of the top 50 Gems in use (from a list of more than 2000.)

Episode #21 - On The Edge - Part 3

Fri, 23 Oct 2009 11:43:00 -0700

This is the last of three screencasts where looking at a couple new libraries to help you scale your Rails applications. In this episode we start by learning about rubber, a capistrano/rails plugin that makes it easy to deploy/manage/scale on Amazon EC2. Then we look at a background job system with a killer user interface called Cloud Crowd. Lastly we look at a web service called Mad Mimi, which allows you to keep track of mailing lists and even move all of your mailer erb templates out of your web application. Utilizing Mad Mimi’s API can give your customer more control of their mailing lists, and alleviate some developer frustration surrounding email.

To keep up to date with additional libraries which may help with Scaling, be sure to listen to the Ruby5 Podcast.

Episode #20 - On The Edge - Part 2

Fri, 23 Oct 2009 11:40:00 -0700

In this screencast we discover what typically causes Ruby server memory bloat, namely instantiating too many ActiveRecord objects. Thankfully there are several plugins which can help you detect when your application needs some help, and where your application is hurting the most. We start by taking a look at Rack-Bug, a toolbar which places all sorts of statistics about each requests at your fingertips. Next, we look at two libraries to help specifically track memory bloat; Memory Logic and Oink.

Episode #19 - On The Edge - Part 1

Fri, 23 Oct 2009 11:35:00 -0700

This is the first of three screencasts where we begin to look at a few new Rails libraries to help you scale your Rails applications. In this first episode we take a look at Bullet, which will help you optimize your SQL queries by giving you growl notifications when you’re not using eager loading properly or should be using a counter cache. Then there’s Rails Indexes which provides Rake tasks to find missing indexes in your database. Finally the last library we’ll learn about is Scrooge, a SQL query optimizer which can reduce the amount of data getting sent from your database to your Rails application.

All of these libraries I learned about from the Ruby5 Podcast, a twice weekly audio podcast covering the latest news in the Ruby and Rails Community.
