Velocity 2013 Day 3: benchmarking the new front end

By Emily Nakashima and Rachel Myers

Talking about their experiences at mod cloth…..

Better performance is more user engagement, page views etc…

Basically, we’re trying to improve performance because it improves user experience.

A quick timeline on standards and js mvc frameworks from 2008 till present.

NewRelic was instrumented to get an overview of performance and performance metrics; the execs asked for a dashboard!! Execs love dashboard 🙂

Step 1: add a cdn; it’s an easy win!
Step 2: The initial idea was to render the easy part of the site first- 90% render.
Step 3: changed this to a single page app

BackboneJS was used to redesign the app to a single page app from the way the app was structured before.

There aren’t great tools for Ajax enabled sites to figure out perf issues. Some of the ones that they used were:
– LogNormal: rebranded as Soasta mpulse
– newrelic
– yslow
– webpagetest
– google analytics (use for front end monitoring, check out user timings in ga)- good 1st step!
– circonus (which is the favorite tool of the presenters)

Asynchronous world yo! Track:
– featurename
– pagename
– unresponsiveness

Velocity buzzwords bingo! “Front end ops”

Velocity 2013 Day 3: DevOps and metrics

We’re talking about the devops survey with Gene Kim, James Turnbull and Jez Humble

4039 survey responses!

Lessons learned
– Don’t change questions midway in a survey
– Get a data analyst for survey analysis

Key findings
– devops teams are more agile; 30x more deployments, 8000x shorter lead times
– devops teams are more reliable;
– most teams use version control- 89%
– most teams use automated code deployments- 82%
– the longer you do devops, the better you get!

Hilarious John Vincent quote on devops:

Measuring culture
Trust and verify

26% of folks who responded to the survey were from the enterprise, and 16% were from 10k and plus.
The biggest barriers to devops was culture because people didn’t get it- whether it was your manager, team or outside the group. Tell people more, and wear more devops shirts!!!

DevOps continues to be a culture issue versus an issue in terms of tools and processes. James Turnbull wants us to go out there and talk to people and figure out people skills!
