About XITE
XITE is the music brand for millennials and broadcasts 24/7 the most popular music videos. XITE went live in 2008 and became the largest music channel in the Netherlands and Belgium shortly after. XITE is distributed to 15 million households in the Netherlands, Belgium, Germany and Qatar, and is expanding globally. In 2015 XITE released a world’s first: Personalised Music Television, which allows viewers to personalise their music channel by liking and skipping music videos. Visit for additional information.
We’re building a project which is a back end for interactive television that gives content recommendations in real time. This platform has very high performance and stability requirements. Such as SLA on response time and service availability. The platform is a RESTFul service built purely on Scala with Akka and Spray frameworks. It is designed as a reactive microservice managed by Kubernates framework to work in the cloud. We’re building the microservice base on reactive manifesto principles. We heavily rely on concurrency and parallelism to reach performance. For that we’re using corresponding algorithms and data structures to implement actor centric design and caches. As the core of our recommendation algorithm we use Neural Network which allows us to start recommending at the very beginning and works in real time (average response time is ~50ms). This is a nohow solution build domestically as a PoC.
