Forking OpenFaaS Faasd to support Firecracker Containerd
As part of my research, I needed to evaluate the performance of Firecracker in serverless environments compared to traditional Linux containers. OpenFaaS, with its modular design, offered an excellent framework for this comparison. OpenFaas offered two running modes, which were OpenFaas using Kubernetes and faasd. Firecracker-containerd isn’t directly supported by Kubernetes due to the lack of a stable CRI plugin unless you consider the now unsupported Firekube. Extending faasd to support Firecracker is simpler and served as sufficient proof of concept from my research. Otherwise, from a general point of view, the primary advantage of Firecracker over LXC in serverless computing is isolation, which isn’t crucial if you’re running faasd since serverless loads on faasd are typically trusted. So, there is no big need to do this other than plain curiosity.
