Containers and virtual machines are two ways of running virtualized infrastructure. Containers use less resources than VMs, and typically use the runc open source container runtime. Sysbox is a containerization runtime that offers an alternative to runc, and allows for the deployment of Docker or Kubernetes within a container. Cesar Talledo is the founder of Nestybox, a company built around the Sysbox runtime. He joins the show to talk about container runtimes and his new company.
