With cloud computing, we started with virtual machines. They allow us to virtualize an entire server, while providing strong isolation and security. Then containers came along. They allow us to virtualize just our applications, making containers faster and less resource intensive than VMs. But with these gains we lose strong isolation. What if we could have the speed and resource efficiency of containers coupled with the enhanced security and isolation of VMs? In this episode of Mobycast, Jon and Chris kick off a three-part series on the future of containers. We dive deep on microVMs, unikernels and container sandboxes, understanding what they are, how they work, and how well they combine the best of both VM and container worlds.
