Firecracker is an open source virtualization technology that is purpose-built for creating and managing secure, multi-tenant container and function-based services that provide serverless operational models. Firecracker runs workloads in lightweight virtual machines, called microVMs, which combine the security and isolation properties provided by hardware virtualization technology with the speed and flexibility of containers.
 
The main component of Firecracker is a virtual machine monitor (VMM) that uses the Linux Kernel Virtual Machine (KVM) to create and run microVMs. Firecracker has a minimalist design. It excludes unnecessary devices and guest-facing functionality to reduce the memory footprint and attack surface area of each microVM. This improves security, decreases the startup time, and increases hardware utilization.
 
Firecracker was developed at Amazon Web Services to accelerate the speed and efficiency of services like AWS Lambda and AWS Fargate.

Firecracker - Secure and fast microVMs for serverless computing

Flatpak is the next-generation technology for building and installing desktop applications. It has the power to revolutionize the Linux desktop ecosystem. Flatpak (formerly xdg-app) is a software utility for software deployment, package management, and application virtualization for Linux desktop computers. It provides a sandbox environment in which users can run applications in isolation from the rest of the system.
 
Unlike package managers, Flatpak can safely update applications on the fly. Its sandboxing technology prevents exploits and hinders malicious applications. It can simultaneously install multiple versions of the same application.
 
Flatpak helps to create one app bundle and distribute it to the entire Linux desktop market. Developers can develop and test their application in an environment that's identical to the one users have.
