With increasing demand for web applications, WebAssembly paired with Kubernetes shows promise for making versatile and manageable web apps. If you are trying to spin up on bare metal, take a look at OpenShift, but recognize that you lose some of the magic of Kubernetes in this setup. Both of these orchestration tools offer much of the similar functionalities.
In essence, Docker makes it extremely easy to leverage Linux containers to package applications in a simple format known as Docker file. You can quickly send your software out into the world and have it up and running in no time — it’s like a fast-track delivery service. Kubernetes and Docker share some similarities, such as high availability, portability, https://deveducation.com/ and the ability to break down applications into their constituent parts. While Docker can be used independently, using Kubernetes alongside Docker can help improve the scalability, availability, and performance of containerized applications. By leveraging both tools, these companies can manage their containerized applications at scale.
Preference for Docker and Kubernetes
Like Docker (the platform, not the company), Kubernetes is an open source platform, though it is managed by the Cloud Native Computing Foundation as a project with more than 2,300 contributors. Kubernetes works like an operating system for the cloud, streamlining and simplifying management across virtual machines and clouds so that What Is Docker IT departments can handle things at scale. Kubernetes and Docker contain all the tools you need to develop your containerized applications. Both of the DevOps solutions depend on image registries (such as those hosted on the likes of Docker Hub) and use JSON-formatted manifests to layout portable, containerized applications.
Kubernetes was originally designed by Google and is now maintained by the Cloud Native Computing Foundation. However, they are fundamentally different in how they work and what role they play in distributing containerized applications. Each microservice is individually made up of multiple containers itself.

Kubernetes is an open-source container orchestration platform for managing, automating, and scaling containerized applications. Kubernetes is the de facto standard for container orchestration because of its greater flexibility and capacity to scale, although Docker Swarm is also an orchestration tool. Docker is often used for deploying a single container to a either a standalone host or a cluster called a Docker Swarm. Kubernetes is an open-source container orchestration platform that makes it possible to manage, automate and scale your containerized applications and microservices.
The initial parameters can be issued using the command line or described in a manifest YAML file. Kubernetes has a rich ecosystem of tools designed to extend its functionality. These tools can be divided into several categories, according to the aspect of Kubernetes they improve upon.
Kubernetes vs Docker: What’s the difference?
One common question is whether someone should use Docker vs Kubernetes for managing their application containers. For a long time, Docker was the default container runtime used by Kubernetes. Today other alternative container runtimes such as containerd and CRI-O have become popular. Kubernetes groups the containers that support a single application or microservice into a pod.
It works great for PoC or development environments, but lacks a lot of the capabilities that are more or less table stakes for serious production use. Swarm is more production-ready, but I would never invest into Swarm in a greenfield scenario. Kubernetes has won the orchestration battle, as evidenced by its inclusion into Docker Desktop and it being offered by all major cloud providers. Kubernetes is much more capable and has far more community and corporate support.

- Oracle Cloud Infrastructure offers a number of services to accelerate and build modern cloud native applications.
- Kubernetes separates the node that controls activity in the cluster from the other nodes.
Since containers are system-agnostic, Docker is a frequent choice for developing distributed applications. While both tools deal with containers, their roles in the development, testing, and deployment of containerized apps are very different. AWS has several container services that make managing your underlying container infrastructure easier, whether on premises or in the cloud.
