The always-on DeNA infrastructure is powered by Ubuntu. When Canonical released Livepatch in October 2016, with the ability to patch servers without downtime, DeNA saw an opportunity to reduce its operational costs. Traditionally, the process of upgrading and patching an OS can be long and complex, including workload migrations and manual interventions. Moving to an automated way to perform upgrades and security patches of its Ubuntu servers without downtime meant that DeNA could eliminate these OS upgrades. The Canonical Kernel Livepatch Service enables runtime correction of critical security vulnerabilities in the kernel without the need to reboot. It is the best way to ensure that machines are safe at the kernel level, while guaranteeing uptime, especially for container hosts where a single machine may be running thousands of different workloads. DeNA now has hundreds of nodes in operation using Livepatch and has found the experience to be outstanding. As Mr. Masaaki Hirose (IT Platform Dept.) says, “Our users and business partners expect nothing less from DeNA than complete availability, reliability and security. Livepatch is like a dream come true, both from a technical and a business standpoint. Our Ubuntu systems now rarely or never have to be rebooted. Service is continuous. That makes a big difference for user and customer satisfaction and loyalty.” **About DeNA** DeNA (pronounced “D-N-A”) develops and operates a broad range of mobile and online services including games, e-commerce, entertainment, healthcare, automotive and other diversified offerings.
