Docker vs. Oracle VirtualBox

You are going to be able to find the most resources and examples using Docker whenever you are working with a container orchestration software like Kubernetes. There will always some entropy when you run in a container, a containerized application will never be as purely performant as an app running directly on the OS. However, in most scenarios this loss will be negligible to the time saved in deployment, monitoring, etc.

It is best suited when you want to have different operating systems on your laptop or desktop. You can easily switch between operating systems without the need to uninstall one. In another scenario, if you expect some application to damage your device, it would be best to run the application on the VM such that the damage can only be done to the virtual machine. It is less appropriate when time synchronization is very important. At times the VMs run their own times differently from the host time and this may cause some losses if what you doing is critical. Another important thing to take note of is the licensing of the application you want to run your VM. Some licenses do not allow the applications to be run on virtual servers so it is not appropriate to use the VM at this time.

• Kubernetes context switching - very handy
• Integrate well and seamless - No complicated setup and or UX
• Ease of updating images and etc - very important

• Can spin up multiple VMs on a host-only network that speak to each other and allow for interesting test environments spun up at will.
• Cross-platform functionality allows me to run it on my Linux Desktop and know that tutorials I make with it could be approached by someone on a Windows or Mac OSX system. Hyper-V is limited to Windows, and VMware Workstation requires a license (VMware Player is free, but is not open-source and is more limited in comparison to VirtualBox).
• If you are testing tools like Vagrant and Test-Kitchen, VirtualBox often seems to have the highest amount of support and documentation when it comes to compatibility (though, many people do use Hyper-V or VMware Workstation without issues).

Incentivized

• It will be nice to see an admin UI for configuration of images
• Container networking can be simplified
• Data storage/volume management can be simplified

Incentivized

• The memory footprint is high, and requires above 8 GB of memory to run an Ubuntu VM smoothly (considering developing inside ubuntu OS inside a MacBook Pro).
• Some known issues with OVF/OVA images import/export. We had the issue of some sections in OVF being ignored (especially Startup and Install sections).
• Some intermittent issues when mounting external hard drives and trying to access them from within the running VM.

I give this rating because virtual box is inexpensive but there is another product such as vm ware that can also be used

I have been using Docker for more than 3 years and it really simplifies the modern application development and deployment. I like the ability of Docker to improve efficiency, portability and scalability for developers and operations teams. Another reason for giving this rating is because Docker integrates CI/CD pipelines very well

I love using the Graphical User Interface. The VirtualBox Manager is very easy to understand and use. You can quickly create, configure and manage all your virtual machines in one window. It makes operating virtual machines easy and simple. When using VBoxManage it gives the user comprehensive control over VirtualBox so that you can use automation and scripting at the command-line interface

Haven't seen any outages, fatal/unrecoverable errors in my usage so far. Enough said.

Dependency on the Host OS means it is as reliable as it is possible to be. Application errors are beyond the purview of the application.

Docker Desktop. The CPU high usage is a known issue. Needs fixing. Otherwise, it is great overall. Would not use anything else still.

No issues, especially with the extensions addons.

Oracle have a very fast response rate and a strong user community. One can geet help from many sources if they choose to research for themselves.

We really enjoy using virtual box. We do not require to buy expensive hardware but instead we can minimize costs and maximize profits.

We need a solution where initially we can use an OS to trigger our pipeline to be used by terraform and then later in ansible. After doing all work it automatically get exited and we can reclaim the space of our VM. So we created a gitlab pipeline and at the initial stage we defined a docker file which will be our base image and we performed all our activities inside that image to build infrastructure using terraform. Integration we have done in our gitlab pipeline and finally we remove the docker image so that the space can be reclaimed immediately.

VirutalBox is very similar to using Vmware with the slight difference in appearance and what might be considered a less polished look. However, what it lacks in polish and looks it makes up for in functionality, easy of use and the wide range of operating systems and features it supports without the need of buying the full professional edition

It is the only tool in our toolset that has not [had] any issues so far. That is really a mark of reliability, and it's a testimony to how well the product is made, and a tool that does its job well is a tool well worth having. It is the base tool that I would say any organisation must have if they do scalable deployment.

The only problem I have found is that the deployment is dependent and intrinsically linked to the Host OS. This is different from bare metal solutions which remove that dependency on a Host OS. The latter is more reliable and removes a layer of potential failure.

• With Docker adoption, were able to reduce 40% of the time taken to complete workspace setup
• Provided the environment packaging / configurability capability which enabled resource sharing and interoperability across teams
• Were able to leverage off the shelf images provided by leading product companies which increased reliability and security exponently

• Direct cost savings - it enables me to do the work I need to do without purchasing additional physical computers
• Time savings - it allows me to perform testing and reversion that would take much longer on a physical computer
• Increased productivity - it enables me to more easily integrate with customer environments
