In web operations, monitoring is the main interface to our applications. A monitoring system alerts us, interrupts us, awakes us. When it does, maybe the site is on fire (signal), maybe a new application broke old monitoring assumptions (noise). Noisy monitoring leads to outages, frustration and resentment. How do we cut the noise and turn monitoring from necessary evil into operational strength?

Most of us think of Jenkins as a build server, but it can be so much more. The flexibility of Jenkins makes it an interesting tool to add to your operations toolkit. Make Jenkins the next member of your Operations team, automating tasks like syntax checking before restarting services like Nagios and BIND, ensuring that tests pass before affecting production.
Dropbox is used by over 200 million people to store their valuable data. Achieving such scale inevitably comes with unexpected challenges, tough decisions, and valuable lessons. In this talk, we'll discuss why and how we started by being hosted on AWS and colocation services to our current hybrid model that combines the unique strengths of AWS and dedicated hardware.
When raw data becomes overwhelming, we turn to abstraction to understand our world. In our systems, the data is always overwhelming. Solutions like summary statistics have come to our rescue, and they are good -- up to a point. In order to truly understand our systems, we need to know when and how to sidestep those abstractions, to get deep, detailed performance insight.

Stack Overflow is a developer-centered Q&A site handling 3 billion requests per month using a variety of platforms and products to deliver content. With a small sysadmin team, building our deployments, applications and architecture for ease of management and maintenance is key. Most of what’s used is an application of widely available open-source, or written in-house and open-sourced for you.
Program Chairs, John Allspaw and Steve Souders round up the conference with a recap.
Oftentimes security seems like a daunting challenge which many organizations aren't sure how to get started on. However, the engineering principles inherent to devops and continuous deployment lay the groundwork for a number effective security mechanisms.

Synthetic performance monitoring is a key piece of our monitoring toolkit, since it provides stable data over time and more in-depth information than you can get from RUM. Everyone loves WebPagetest, but the public instance isn’t great for high volume testing and trending over time. We’ll explain how Etsy uses a private instance to fill this need, and share the code that drives our tests.
In this session, learn how to measure and monitor a content delivery network that's operating at a very large scale. We’ll review best practices on how to measure and eliminate bottlenecks to significantly improve global purge-from-edge time, track outliers during core cache/proxy engine deployments, and identify and find our way around quirks in the TCP stack.
Keynote by Fred Wilson, venture capitalist, Union Square Ventures.

In Jan 2012, HTTP Archive reported as taking 15s to load. By Apr 2013, this page was loading in 3.6s, with 5 additional sites showing significant improvements from the previous year, some as fast as 2s. How did we do it? What worked or didn't work? Come learn about what we did, the techniques we used, and how faster pages impacted our business results.

Braintree is a payment gateway, so downtime directly costs both us and our merchants money. Therefore, high availability is extremely important to us. This talk will cover how we do HA at Braintree on our Ruby on Rails application, including no-downtime deploys and load balancing across services and ISPs.
The real challenge of running an effective post-mortem is the complex, messy, all-too-human *feelings* of everyone involved. This talk gleefully tackles that challenge head on, and lays out effective techniques for helping a team to learn as much as possible after a public (and generally, pretty shameful) failure.

In the startup world, the most pressing issue usually isn't, "how to we prepare for a once-in-a-lifetime storm?" Risk management is always stressed at Velocity, but businesses don't always buy into dedicating resources to low probability events. Let our comedy of errors during Hurricane Sandy help to convince your bosses that infrastructure and redundancy are actually worthwhile investments.
An Informative Workspace can benefit almost any team, but it is sometimes difficult to allocate the time or budget to set it up. This presentation will describe the steps needed to easily create an inexpensive, state-of-the-art informative workspace using a Raspberry Pi, inexpensive TV, and a few basic electronics.
