Docker Swarm vs OpenFaas

Docker Swarm — Docker Swarm is a native clustering solution for Docker containers that turns a group of Docker engines into a single virtual Docker engine. It allows users to manage multiple Docker hosts as a cluste

OpenFaas — OpenFaas is an open source framework for building serverless functions. It has advanced functionality for auto-scaling and automated deployment of functions.

Docker Swarm offers Native clustering for Docker, Turns multiple Docker hosts into a single virtual host, Load balancing, Service discovery, Scaling services across hosts, while OpenFaas provides Serverless functions, Auto-scaling, Multiple language support (Node.js, Python, Ruby, C#, etc), Open source, CLI for easy deployment.

Docker Swarm stands out for Easy clustering of Docker containers, Horizontal scaling, High availability; OpenFaas is known for Easy and fast to deploy functions, Scales automatically based on load, No servers to manage.
