In order to maintain confidence in a rapid release cycle, you need to be monitoring your application first. And to truly understand your application, you need to view it through multiple metrics. Monitoring CPU, memory and I/O usage is traditional. We also want to monitor page render times, database calls, and network latency. But none of those are the most important metric. We must be monitoring our application at the business level. How many sign-ups were processed? How many shopping carts were abandoned? How many login attempts failed?

These metrics give us significant insight into how the code changes affected the application’s performance. By monitoring at these levels, we can easily detect regressions and get fixes out to production quickly. We want to focus on our mean time to response (MTTR) and not our mean time between failures (MTRF). So we need the tools to both fail fast and recover fast, and monitoring is critical to both.

The impact of DevOps has grown over time, particularly within today’s competitive and face-paced IT environment. The abundance of programming languages, tools and software services has created near-unlimited options for developers to build and create innovative applications. But to remain agile, the creator is also the implementor. The line between developer roles has become blurry and it is no longer sufficient to be an expert in one particular area. From the small startup to the large enterprise, teams are embracing DevOps culture to push their applications forward and respond to changes quickly. This slideshow, from Chris Kelly, developer/evangelist at New Relic, will discuss five characteristics of a successful DevOps culture.
