Explore the next generation of process isolation techniques in this conference talk on container security. Examine the history of safely running unsafe processes, compare emerging isolation and security methods, and understand the design decisions driving each project. Learn about breaking in and out of different technologies, and discover which workloads are best suited for various isolation techniques. Gain insights into the challenges of running untrusted code in containers, the evolution of process isolation, and the blurred boundaries between containers and micro VMs. Understand the implications of different isolation technologies for your applications and how to potentially run diverse workloads on the same cluster using different "container" types.
