The Stateless Service design principle has become ubiquitous in the tech industry for creating horizontally scalable services. However our applications do have state, we just have moved all of it to caches and databases. Today as applications are becoming more data intensive and request latencies are expected to be incredibly low, we’d like the benefits of stateful services, like data locality and sticky consistency. In this talk I will address the benefits of stateful services, how to build them so that they scale, and discuss projects from Halo and Twitter of highly distributed and scalable services that implement these techniques successfully.

Almost 2 years and over 16 million domain events ago I’ve started a process of “switching the mindset". I had no production experience with Event Sourcing (BTW it still is used only in some parts of the application, but that’s a topic for another post), I had only a limited experience with Domain Driven Design (mainly knowing the tactical patterns). During that time, a lot has changed.

A big chunk of the FullStory engineering team formerly worked at Google, where there is a famously strong emphasis on code quality. Perhaps the most important foundational tenet at the big G is a practice called code reviews, or, more precisely, “pre-commit" code reviews. We continue the practice at FullStory and hold it as sacrosanct.

.NET Core and ASP.NET Core RC2 Released and Announcing ASP.NET Core RC2

We are very pleased to announce the availability of ASP.NET Core RC2. This release succeeds the ASP.NET 5 RC1 release and features a number of updates to enhance compatibility with other .NET frameworks and an improved runtime. You can install the RC2 from http://dot.net.

The actor model is an old technology, originating in 1973 as an approach to parallel computing at a time when it looked like the computers of the future might be constructed using thousands of small, low-powered CPUs. History didn’t turn out that way thanks to Moore’s Law; CPUs became faster and faster and modern machines were developed with a small number of very high-powered CPUs.
