Docker swarm.

create a cluster of machines - swarm cluseter: manager and worker nodes

manger and worker both take the load, replicas are created on MANAGER node as well as worker node

> with 1 GB nodes we can create a cluster

> that can orchestrate docker container only

> Bridge/ Overlay n/w

Kubernetes:

you have cluster of machine : cluster of menions : kube or k8s cluster

MASTER and SLAVE and in k8s MASTER will not take any replicas, all replicas will be on slaves

> high configuration machine to create the master and slave, atleast 4GB & 2 CPU core

> can orchestrate containers of any type:

> docker

> RKT

> CRIO

> Container-D

> we have to set up our n/w in K8s : CNI
