Difference Between LXD and Docker
There are many container management tools that are used to create, deploy, and scale containers. LXD and Docker are two of the tools which work efficiently so that the containers can be easily maintained and applications can be easily developed. In this article, we will discuss the difference between LXD and Docker.
What is LXD?
The full form of LXD is Linux Container Hypervisor. This is an open-source container management system which is used for Linux Containers. The developer of LXD is Canonical Ltd. LXD is also known as image-based platform as a large number of images are provided for different types of Linux distributions. Another feature of LXD is that it can work with cloud platforms.
What is Docker?
Docker is a platform which can be used as a CaaS that can be expanded to Container as a Service. Docker Inc. developed Docker in 2013 and the Go programming language was used to create the container. Developers can develop, test, and deploy applications easily through this platform.
Difference between LXD and Docker
Here is the table which shows the difference between LXD and Docker.
| LXD | Docker |
|---|---|
| OpenNebula and OpenStack are the systems with which LXD can be integrated. | The tools with which Docker can integrate are Jenkins, Kubernetes, and Ansible. |
| Canonical Ltd. Is the developer of LXD. | Docker Inc. is the developer of Docker. |
| A single container has the ability to run multiple processes. | Each process needs a single container to run. |
| LXD works as an operating system virtualization by using a system container. | Docker works as an application virtualization and uses an application container. |
| It is not a good option for beginners as its usage is very difficult. | Docker can be used easily by beginners and experts. Another advantage is that it has been documented well |
| LXD is not very popular in comparison to Docker. | Docker is more popular than LXD. |
| Application executes at a fast speed because of multiple processors. | Docker works fast when a single process is to be executed. For multiple processes, Docker is slow. |
| The platform on which LXD can run is Linux. | Docker can work on Windows and Linux. |
| LXD works in a complete operating system environment and is not portable. | Docker is portable. |
| The performance of the memory and RAM is slow. | The performance of the memory and RAM is slow. |
Similarities between Docker and LXD
The similarities between LXD and Docker are as follows ?
- Isolated processes are created by both platforms as they share the Linux kernel with the host operating system.
- Many tools are available on both platforms for networking, storage, and management of containers.
- Containers can be managed by both of them with the help of daemon-based run time.
Which is better: LXD or Docker?
LXD and Docker are container applications and both of them have their own advantages. LXD can run multiple processes at a time while each process needs a separate container in Docker. The performance of LXD is faster but it is not good for beginners. Docker is an easy-to-use tool.
Conclusion
Docker and LXD are the platforms which are used to create and manage containers. LXD is used for Linux containers while Docker can be used with Windows and Linux. Both of them share a Linux kernel with the host operating system.
FAQs on Docker Vs. LXD
1. What is Hypervisor?
Hypervisor is a software application which can be used for virtualization. This is the reason it is also named as Virtual Machine Monitor. The system is divided into various divisions and resources are allocated to each division. Multiple operating systems can run on a single host system in Docker.
2. What is a Docker Container?
Docker containers can be used for sharing the Linux kernel with other containers on the host operating system. Docker containers are easy to use and are suitable for any type of computer.
3. What is a Docker Image?
Docker images are used to create containers. A container is created as soon as a Docker image runs. The deployment of the Docker images can be done anywhere.
4. Who developed Docker and LXD?
Docker was developed by Docker Inc. in 2013 while LXD was developed by Canonical Ltd.
5. Which operating systems are supported by LXD and Docker?
LXD can run only on Linux while Docker can run on Linux and Windows.
