Explore a modern approach to serverless computing that combines container flexibility with virtual machine security through this 27-minute conference talk from DevConf.CZ 2025. Learn how Serverless MicroVMs address the limitations of traditional serverless platforms by providing stronger isolation and enhanced multi-tenant security using Firecracker, AWS's lightweight virtual machine monitor, and Ignite for Docker-like microVM management. Discover techniques for running OCI container images inside microVMs within seconds, launching secure short-lived workloads with Ignite, orchestrating microVMs in Kubernetes using Kata Containers runtime, and deploying serverless functions with improved isolation and control. Follow along with a live demonstration showing the provisioning of Firecracker microVMs with Ignite, their integration into Kubernetes clusters, and execution of real serverless functions within lightweight VMs. Gain insights into use cases, architecture patterns, and how microVMs are transforming secure, scalable infrastructure in cloud-native environments, making this session essential for developers seeking enhanced security and performance in serverless workloads.
