Kubernetes vs. Docker Swarm – What’s better?

  • Post published:September 22, 2020

Do you know about k8s? No, it is not a cryptic code. It’s Kubernetes vs docker swarm and holds greater importance especially for those looking for the best container management platform. The shift from docker swarm to Kubernetes comes under the container technologies. Let’s dig in!

Kubernetes or k8s, as you might have guessed is the talk of the town. It is part of container technology. What are container technologies? What do they do for us?

Container technologies have this unique tendency to provide ease with inbuilt solutions. Imagine a container, that contains all the goods, files, and required material. So if you were to shift that very material to another place, instead of moving the stuff separately. You’d move the container without creating any fuss. Yes, that’s what container technology is accomplishing as its reigns in the cloud computing world.

The link between container technology and your business

You need to understand the background, in order to comprehend the real reason behind it. Why do we need container technology in the first place? And why is everyone searching for Kubernetes vs docker swarm?

With the Container technologies such as Kubernetes vs Docker swarm, you can manage applications, run them, and deploy them with all their dependencies. if you understood the above analogy. You can understand how it is often challenging for people to move applications with its dependencies, and run them seamlessly. Those who are currently using Amazon web services, Google cloud computing, and Microsoft Azure are fully aware of the current container-based technology.

By making a fair comparison, you can guess the right platform and tool for you as per your unique business needs. Here’s an introduction to the most popular container platforms at the moment.

A simple introduction to Kubernetes – The buzz

Automate, manage, and deploy your applications with the help of Kubernetes, also known as an open-source orchestration system. It is an effective container management tool introduced by Google. It has made it easier to manage container applications across a cluster. Where you can easily find them and use them for your own benefits. No wonder, it has already beaten Docker. Hence, all the rage about Kubernetes vs docker swarm.

But how?

Wait, we are getting there…

Here’s a little peek into how Kubernetes works?

Kubernetes has a master node, which also has multiple worker nodes. The instructions are given to the “kubelet” within the worker node. You can understand the kubelet as the brain, that is receiving the orders from the Master node and acts accordingly. The hierarchy within the Kubernetes system is very well defined. The worker node is the place, where microservices can run, and its hosts microservices within a specific run time.

What are the major benefits of Kubernetes?

  • With lots of inbuilt features, Kubernetes does the heavy lifting for you with automated operations to save you effort and time.
  • Let k8s handle the workload that includes networking, computing, and storage. So developers will focus on the application without worrying.
  • Monitoring the services and running applications in case of any issue, so that Kubernetes can resolve it with auto-recovery.

With Kubernetes, you can deploy the applications anywhere and even hybrid deployment of apps to reach your audience. Get the most out of Kubernetes as per your unique business needs. Take a look into the link between the deployment process and how Kubernetes plays its integral role consistently.

Why would you shift from Docker to Kubernetes?

The relationship between Kubernetes vs docker swarm is kind of misunderstood. Let’s settle this for once and all. It is not what Kubernetes does and how it can be compared to a docker swarm. But they have their own roles within the management of the containers pertaining to their features.

Docker is an empowering platform for developers and companies to use a standard clustering and scheduling tool for containers. It empowers you to run your code in the same ecosystem, where you have your server

The increase in popularity of Kubernetes vs docker swarm and container technology has also piqued our interest to figure out its background story. What is all the fuss about? Without any further ado, let’s dive right into these amazing technologies.

Note: A “pod” is described as a group of containers present on a similar host.

FeaturesDocker SwarmKubernetes
AvailabilityHigh availability to control the unexpected and undesired with full-on backup mode. Build high availability clusters.High availability, as the pods are effectively distributed among the nodes. However, any failure within pods can be controlled and deactivated immediately.
Container setupSupports the tools within the docker for smooth-running applications. Moreover, if the docker API isn’t cooperating, there is no use of docker swarm.Defines its own standards to utilize its particular YAML and API. Therefore, you’ll have to rewrite the commands for YAML while shifting.
DeploymentYou can install applications as microservices, and with the help of docker-compose.You can easily deploy applications using microservices and pods etc.
GUIUI can be managed by a third party tool within a docker swarm.An easy dashboard is provided to manage and control clusters.
Load BalancingThe services can be assigned by the requests made by users or automatically by the system.Inside the Kubernetes cluster, pods are used as a load balancer.
MonitoringIt is said that docker doesn’t require any tools to carry out a monitoring operation.The system can utilize inbuilt tools for logging and monitoring.
NetworkingIf the node is to join the swarm clusters, it will create its own significant network.It has a flat model, where all the pods within the system interact with one another.
ScalabilityIt allows on-demand scaling at a much faster rate as compared to Kubernetes.Scaling and deployment can slow down due to complicated clusters and distributed systems.

Do you see it? Kubernetes and Docker work together, and not against each other. However, it is important to mention that Kubernetes is much flexible with a modern approach. But of course, two heads are better than one. So, let’s get together and make an easy transition from the docker swarm to Kubernetes.

Make the transition from Docker Swarm to Kubernetes

Do you know? Kubernetes is originated from the Greek language, which translates into “captain.” Just like a captain takes care of the ship, this also uses docker and the latest computing tools to manage, run, and deploy containerized applications to run them at scale.

In fact, Kubernetes enables you to create easy to manage and easy to deploy applications, in a secure and manageable way. For example, if it was deployed on one particular hardware, it can be moved to another one with all its dependencies that include files, libraries, and whatnot.

Take your next step

If you are ready to build applications, that you can scale in no time, at a much faster rate. You can create applications, manage, run, and deploy them with the help of Kubernetes and Docker Swarm. But one cannot just go with the trending technology without any background knowledge. Therefore, we urge you to make an informed decision.
