Docker Swarm

Question

I am an amateur docker learner and have been exploring containerization using docker since few days.I came across this concept of docker swarm.Could you please brief as to what is Docker Swarm and why exactly we need it. Thanks in advance!

Answer 1

Docker Swarm is a technique to create and maintain a cluster of Docker Engines. The Docker engines can be hosted on different nodes, and these nodes which are in remote locations form a Cluster when connected in Swarm mode.

Using a Docker Swarm we can achieve high availability of our web application, load balancing, Decentralized access and many such benefits. For a precise understanding of docker swarm and the way to get started with it and for a bit of hands-on on docker swarm, I suggest you have a look at this article. You would definitely find it useful.
