Advantages of kubernetes over Docker swarm
Docker Swarm Kubernetes
Developed by Docker Swarm Developed by Google
Has a smaller community compared to Kubernetes Has a vast Open source community
Has low fault tolerance Has high fault tolerance
Easy to set up and fits well into Docker ecosystem Requires heavy setup
Less extensive and less customizable More extensive and customizable
Features automated internal load balancing through any node in the cluster Enables load balancing when container pods are defined as services
Facilitates for quick container deployment and scaling even in very large clusters Provides strong guarantees to cluster states at the expense of speed
