Many features like load balancing, health checks, etc, got introduced within Docker. This swarm mode under different environments like your local machine or in a production environment, Docker Engine with Swarm mode enabled helps you in creating and testing services based on images, and provides a fault-tolerant platform for cluster management features for keeping constant running services and availability.
