Kubernetes vs VirtualBox: What are the differences?
What is Kubernetes? Manage a cluster of Linux containers as a single system to accelerate Dev and simplify Ops. Kubernetes is an open source orchestration system for Docker containers. It handles scheduling onto nodes in a compute cluster and actively manages workloads to ensure that their state matches the users declared intentions.
What is VirtualBox? Run nearly any operating system on a single machine and to freely switch between OS instances running simultaneously. VirtualBox is a powerful x86 and AMD64/Intel64 virtualization product for enterprise as well as home use. Not only is VirtualBox an extremely feature rich, high performance product for enterprise customers, it is also the only professional solution that is freely available as Open Source Software under the terms of the GNU General Public License (GPL) version 2.
Kubernetes and VirtualBox are primarily classified as "Container" and "Virtualization Platform" tools respectively.
Some of the features offered by Kubernetes are:
- Lightweight, simple and accessible
- Built for a multi-cloud world, public, private or hybrid
- Highly modular, designed so that all of its components are easily swappable
On the other hand, VirtualBox provides the following key features:
- No hardware virtualization required
- Guest Additions: shared folders, seamless windows, 3D virtualization
"Leading docker container management solution", "Simple and powerful" and "Open source" are the key factors why developers consider Kubernetes; whereas "Free", "Easy" and "Default for vagrant" are the primary reasons why VirtualBox is favored.
Kubernetes is an open source tool with 54.2K GitHub stars and 18.8K GitHub forks. Here's a link to Kubernetes's open source repository on GitHub.
Slack, Shopify, and Starbucks are some of the popular companies that use Kubernetes, whereas VirtualBox is used by Lyft, Starbucks, and New Yorker. Kubernetes has a broader approval, being mentioned in 1018 company stacks & 1060 developers stacks; compared to VirtualBox, which is listed in 721 company stacks and 944 developer stacks.

Sometimes you will need to customize your virtualbox and you can easily add virtualbox commands inside your vagrantfile
Example of USB connection Share Between Host and VM
#Use $VBoxManage list usbhost To list Usb Ports and Get Your Device VENDORID and PRODUCTID v.customize ["modifyvm", :id, "--usb", "on"] v.customize ['usbfilter', 'add', '0', '--target', :id, '--name', 'ESP', '--vendorid', '0x22b8', '--productid', '0x2e76']
It's a little bit complex to onboard, but once you grasp all the different concepts the platform is really powerful, and infrastructure stops being an issue.
Service discovery, auto-recovery, scaling and orchestration are just a few of the features you get.
Just tinkering with it for personal use at this stage based on positive experience using it at work. Plan to use it for high traffic distributed systems if not using a managed hosting service like Heroku, AWS Lambda, or Google Cloud Functions. Reasons for using instead of these alternatives would be cheaper cost at higher scale.
Network and security programs. install and run multiple operating systems. Good to understand computer networks - internet and multiple services, such as the world wide web; and the opportunities they offer for communication (combine a variety of software and services)
We use Virtualbox in combination with Vagrant during development to ensure a consistent test/development environment. This helps to reduce the number of defects when our software goes to production.
For running a VM locally with Vagrant. It can be a little irritable, but it's open source and free, so I'm not complaining. I would probably use VMWare, but I don't want to pay for it right now.
Good existential question. Kubernetes is painful in the extreme - especially when combined with Ansible. The layers of indirection are truly mind altering. But hey - containers are kewl!
Our developer experience system is on Kubernetes (Google Kubernetes Engine at the moment). We would like to expand our Kubernetes clusters over other Kubernetes engine.
Virtualbox is managed by Vagrant and it sets up a local development environment so that anyone can test their changes before pushing the changes upstream.
Kubernetes is used for managing microclusters within our AWS infrastructure. This allows us to deploy new infrastructure in seconds.
minor experience with kubernetes. helped a client setup a kubernetes infrastructure. love the elegance of the system.
