London .NET June 2018

6:30 pm Skillsmatter (CodeNode), CodeNode, 10 South Place, London, EC2M 2RB, GB , London




We’re back at CodeNode on June 7th, with Colm Prunty talking about Windows containers in Production and Benjamin Howarth talking about high-performance web apps in the age of JavaScript.

Colm Prunty: Windows containers? In my production environment? recently migrated their three highest-traffic .NET 4.6 apps (combined 45k hits/min) from a shared server to Windows containers. This talk covers the state of the infrastructure before we started and why we made the decisions we did (including the question “why not Linux”?). It will cover the process of moving a .NET app into a Windows container and also how we do continuous deployment. I’ll also talk about some of the problems we ran into, including a Microsoft networking bug that’s got a fix coming out in June’s patch Tuesday.

Colm Prunty is originally from Dublin, and has been living in London since 2011. He’s been a .NET developer for seven years, after a stint in Japan trying to code C++ in a Japanese language Visual Studio 6. He’s been at totaljobs for two years, and seems to have accidentally drifted somewhat into DevOps. He’s online at and on Twitter @ColmPrunty

Benjamin Howarth: Performance in the JavaScript Era

More than just tips, tricks, metrics and clicks, from code to cloud and back again – performance on the web has gone way beyond “oh just put your CSS in the header and your Javascript in the footer”.

More often approached as an afterthought, this primer will cover some essential ground on how to approach measuring website and web app performance, along with some quick wins, through to some more lower-level technical nuances with HTTP2, compression, and header management, and finally putting all our tools together to comprehensively and continuously keep a watchful eye on your performance metrics.

Topic will include ASP.NET and NodeJS samples, and slides & code will be made available on Github well in advance.

Benjamin Howarth is a freelance ASP.NET architect & senior developer, specialising in open-source content management systems. His experience in high-scale high-performance websites has been a strength over the past 5 years, working for Tesco, FIA Formula E, Universal Music Group, and Manchester Airport Group. He can be found @benjaminhowarth on Twitter.
