N/A
Firecracker is an open source virtualization technology that is purpose-built for creating and managing secure, multi-tenant container and function-based services. Firecracker enables users to deploy workloads in lightweight virtual machines, called microVMs that may provide security and workload isolation over traditional VMs, while enabling the speed and resource efficiency of containers. Firecracker was developed at Amazon Web Services with the goal of improving services like AWS Lambda…N/A

Open Source
While deploying workloads in lightweight microVMs presents a couple of perks, Firecracker may not be the best software to handle this. Startup times are slow and scalability is quite limited because of the jailer and virtualization barriers. We have had security breaches on isolated EC2 instances while using Firecracker. It however has a silver lining by improving how serverless functions in container ecosystems are run with their VMMs.

Linux Containers LXD works very well when you, as a software developer using Linux, need to spin up a development environment to build and work on a specific piece of software. For example, you need to build some software that is tested and developed target Ubuntu 18.04. You're able to quickly create a container for Ubuntu 18.04 and log into it to run commands and build your software. This is easier to do than setting a virtual machine - e.g - via Virtual Box, but is a lot clunkier than doing it via Docker containers which give you a much more flexible configuration of the environment and are easier to start, stop, connect and share with other developers.

Linux Containers LXD feels like a more primitive version of docker, docker-compose and similar projects from the docker ecosystem. The Dockerfile and docker-compose.yml methods of specifying a container setup, as well as the network and file configurations afforded by Docker make working with containers much easier and more reproducible than with Linux Containers LXD.
