Editor to share with you how to choose Linux containers and virtual machines, I believe most people do not know much about it, so share this article for your reference, I hope you can learn a lot after reading this article, let's learn about it!

Linux Container vs Virtual Machine-Application and operating system

One of the first things to learn about containers and virtual machines is that one is used in applications and the other is designed for operating systems. This is why you often see enterprise applications running on containers rather than your own virtual machines. There are some advantages to using containers on virtual machines.

One of the advantages of containers is that they can reserve fewer resources than virtual machines. Keep in mind that the container is essentially a single application, and the virtual machine needs more resources to run the entire operating system.

If you need to run MySQL,NGINX or other services, it is necessary to use containers. However, if you need to run a full LAMP stack on your own server, it is better to run a virtual machine. Virtual machines are more flexible and allow you to choose your operating system and upgrade as you see fit. By contrast, running a configured application container is isolated in terms of operating system upgrades to the host.

Linux Container vs Virtual Machine-use case scenario

One of my favorite reasons for using containers is to use the Linux library version. For example, suppose you need a specific version of Python to develop your application. Then, when you update on the box where the application is running, you suddenly notice that the version of Python has changed, causing the application to not work properly.

Another benefit of using containers is that you can put an application in a container and run it on any operating system that supports the type of container you are running. When you want an application that runs in a different Linux distribution. By using containers, you can run similar application environments on a variety of different distributions. Containers provide portability.

Containers are more feasible for rapid cross-distribution deployment, while virtual machines are better for single application usage such as running the LAMP stack.

Linux Container vs Virtual Machine-Security

Virtual machines provide more security than containers. This is not to say that the container cannot be protected, but that the default virtual machine provides greater isolation. Keep in mind that containers can share system resources but not virtual machines.

When running the container, you can take some measures to reduce the risk, including avoiding superuser privileges, ensuring that the container is obtained from a trusted source, and maintaining a * state. Some containers are digitally signed, which helps to ensure that you can obtain the container from a trusted source.

*, you need to maintain the single functional responsibility of the container. Once you start to combine software responsibilities under a container, you will find that you are still using virtual machines. Again, containers are single-purpose applications and virtual machines are used for multi-purpose applications. If you stick to this approach, you will be in a better position in terms of security and overall functionality.

Linux Container vs Virtual Machine-choose the right tool

Regardless of the type of virtual machine or container, the key to choosing to suit your needs is to study the ability of each option. In the container space, Docker provides powerful enterprise solutions. This attracts companies that follow Docker containers because they know that if anything goes wrong, they can get the support they need. Docker is an enterprise-friendly choice, especially in Docker Swarms. Comparing Docker Swarms with Kubernetes, the setup of Kubernetes in an advanced environment is much more complex.

Going back to virtual machines, I've always found that Virtualbox can provide a better desktop-oriented virtual machine environment. While VMware makes a variety of products on the server side, VMware has a variety of virtual machine solutions from storage to cloud server solutions, as well as other options (various hypervisors, etc.). But I think VirtualBox and VMware represent two areas of desktop-to-server virtualization very well.

Linux Container vs Virtual Machine-who wins?

Before deciding whether a container or a virtual machine, consider the following. If you choose a container, you can run the container on a virtual machine. It's important to understand this because there are no obvious winners or losers. In fact, the requirements of the two technologies are completely different.

Containers will attract constant media attention because they allow users to run more efficiently with less hardware. On the other hand, virtual machines are still the main content of servers and cloud spaces.

What I think is worth looking at is the thing between Kubernetes and Docker Swar. I want to see how these two container management technologies work, and which one will become the standard. For a while, it felt like Docker. Now, however, Kubernetes is occupying more camps. Maybe over time, we will begin to see Kubernetes make headlines and become the number one figure in the container camp.
