Daniel Schauenberg described at QCon London how Etsy, renowned for its DevOps and Continuous Delivery practices, does 50 deploys/day. A fully automated deployment pipeline, thorough application monitoring and IRC-based collaboration are all important to achieve this rate of change while keeping risk to a minimum. Etsy has about 60 million monthly visits and 1.5 billion page views per month.
At a recent London DevOps meetup, Andy Sykes launched a debate on whether Nagios, a well-known application that offers monitoring and alerting services, should be replaced with a better solution. Laurie Denness, from Etsy, argued in a reply that Nagios and its ecosystem still are a great solution in the monitoring and alerting arena.
Microsoft Open Technologies recently announced the release of Tx, an open source project that can help debugging using Logs/Traces, and building of real-time monitoring and alerting systems.
Arun Kejariwal, from Twitter, talked at Velocity Conf London last month about forecasting algorithms used at Twitter to proactively predict system resource needs as well as business metrics such as number of users or tweets. Given the dynamic nature of their data stream, they found that a refined ARIMA model works well once data is cleansed, including removal of outliers.

In a deep dive on performance, Eric Brumer explained why memory is often the most critical component. And while this session was on C++ development, much of what he said is applicable to managed code as well.
The three Pillars of Performance, Fast, Fluid, and Efficient, have been the common theme at the performance sessions this year. In the session XAML Performance Fundamentals we see ways to detect and solve problems that prevent us from achieving these pillars.
Making an application “fast” isn’t a real goal because it can’t be measured. An application may seem fast at first, but as performance starts to slip developers often don’t notice it. But this can be fixed by using a vocabulary that describes application performance in terms of concrete, measurable terms.
CA Technologies’ Application Performance Management 9.5 adds the ability to detect and analyze unusual performance metric patterns in near real time. This can be used to detect the beginnings of a denial of service attack, failing hardware, or a rouge application.
