Outbrain Achieves Operational Efficiency with Cumulus Linux CUMULUS NETWORKS CASE STUDY OUTBRAIN + CUMULUS LINUX "Building flexible, reliable and automated network infrastructure is key to enabling the hyper growth of our business, and we were able to achieve this goal with Cumulus Linux" — Orit Yaron, VP Cloud Platform, Outbrain Overview Outbrain is the world's leading premium discovery platform, reaching a highly engaged audience through distribution on the world's biggest and best publisher sites, including CNN, ESPN, Time Inc., Le Monde, Fox News, The Guardian, SPH, The Telegraph, New York Post,, Sky News, TF1, Condé Nast, Orange, Spiegel, L'Equipe, and more. Outbrain helps its customers understand their audiences through data resulting in increased website traffic and sales revenue. Founded in 2006, the company is headquartered in New York with a presence in a growing number of locations globally, including the U.S., UK, Israel, France, Germany, Singapore, Japan and Australia. Challenges Outbrain has grown into a business that serves more than 250 billion monthly content recommendations, reaching in the region of a billion users every month across the globe. With an upcoming network refresh, Outbrain began evaluating solutions that would help it optimize its infrastructure, so that it could continue to serve the most relevant content to readers at scale. With complex, large-scale requirements and continued rapid growth at the forefront of its considerations, Outbrain wanted to adopt a next generation architecture that would provide standardization, scalability and predictability of the network behavior. They also wanted to enable automation and the ability to leverage the Network and Linux talent that existed in-house. It was critical for the Outbrain team to select a solution that allowed zero-to-full deployment without any human touch. It also wanted the ability to use its existing agent-based monitoring (Prometheus) and automation tool (Chef) across the stack. Solution To reduce Layer 2 complexity, Outbrain decided on Layer 3 Clos architecture. The team considered solutions from multiple vendors and settled on Cumulus Linux due to the flexibility and choice it delivered. A modern data center architecture with Cumulus Linux helped Outbrain to reduce the infrastructure complexity, standardize on the OS and gain operational efficiency. With a Linux OS across the stack and ability to leverage its existing talent, Outbrain was able to reduce its OpEx and streamline operations. INDUSTRY: AdTech and SaaS BUSINESS OBJECTIVE: Reliable, Scalable and Operationally Efficient Network PARTNERS: Chef and Dell
