Lift: A General Purpose Architecture for Scalable, Realtime Machine Learning

In the last few years, we’ve witnessed explosive growth in the role machine learning (ML) plays in technology. Making good predictions from data has always been important in our industry, but modern machine learning techniques allow us to be much more systematic. However, this wealth of new ML algorithms and services present new challenges for software developers.   (more)

Orchestration for a Virtual Network

Our next generation network is basically built with mostly virtual network functions. These are services that ViaSat has migrated from custom/purpose built hardware to a virtual platform. One key component for construction of virtual networks is orchestration. It ties the deployment of the virtual network functions with the rest of the network using the network controller service that I wrote about in my last blog.

Virtual Service Provider Networks

The service provider network is the essential pipe that delivers connectivity to enable innovation. It has the potential to limit or expand the innovation that people and applications riding on it can deliver. With the advent of new apps, games, and devices, the demands on the network keep changing almost every day. The traditional service provider network that took months (if not years) to evolve is not able to keep up with the demand.

At the same time, ViaSat is launching next-generation satellites that have capabilities to cover the whole planet with high speed internet. In order to be more agile, we at ViaSat embarked on a journey to create the next generation network that supports a worldwide and ever-changing footprint.   (more)

Five Years, Five Networks

My name is Stephan Kemper. Today, I lead ViaSat’s Cloud Engineering team, called VICE. VICE is responsible for helping groups all over ViaSat learn what it means to develop for the cloud, as well as supporting and protecting the cloud networks that ViaSat operates. There are at least a dozen groups using public cloud platforms today, with more being added to the list all the time. By far, the majority of this all takes place on the excellent Amazon Web Services platform, though we also use Microsoft Azure and OpenStack to some extent. To kick this blog off, I wanted to tell the story about how ViaSat got here, and the things we learned along the way.   (more)
