Lightweight
LXC containers share the host operating system's kernel, resulting in lower overhead compared to virtual machines. This means higher efficiency and speed, ideal for applications requiring fast start-up times and lower resource usage.
Resource Isolation
LXC provides a level of resource isolation, allowing users to manage CPU, memory, and other resources per container, which helps in optimizing resource allocation and ensuring better performance.
Flexibility
LXC offers a high degree of flexibility, allowing users to run a variety of workloads, from simple applications to complex, multi-service environments, due to its lightweight nature and ease of management.
Security
LXC provides a secure environment through namespace isolation, cgroups, and other Linux security modules, enhancing the security by isolating the processes within containers from the host system.
Ecosystem and Support
LXC benefits from a robust ecosystem and community support, providing numerous tools and integrations with other systems, making it easier to deploy, manage, and orchestrate containers.

Check the traffic stats of LXC on SimilarWeb. The key metrics to look for are: monthly visits, average visit duration, pages per visit, and traffic by country. Moreoever, check the traffic sources. For example "Direct" traffic is a good sign.
Check the "Domain Rating" of LXC on Ahrefs. The domain rating is a measure of the strength of a website's backlink profile on a scale from 0 to 100. It shows the strength of LXC's backlink profile compared to the other websites. In most cases a domain rating of 60+ is considered good and 70+ is considered very good.
Check the "Domain Authority" of LXC on MOZ. A website's domain authority (DA) is a search engine ranking score that predicts how well a website will rank on search engine result pages (SERPs). It is based on a 100-point logarithmic scale, with higher scores corresponding to a greater likelihood of ranking. This is another useful metric to check if a website is good.

In the world of software development, it is all too common to come across the phrase: "But it works on my machine!๐ป" This phrase is mainly associated with when developers are deploying their application for their users or a client, but the software fails to work as expected in production, yet it still works perfectly in development. This problem is mostly as a result of differences in the environment (The OS,... - Source: dev.to / about 1 month ago

Working with legacy applications that needed full system access taught me that a different way to do containerization is by using LXC/LXD. The focus in system containers, rather than application containers, can be thought of like a light VM rather than what most consider the typical container. - Source: dev.to / over 1 year ago

Linux Container Daemon (LXD) is a container and virtual machine manager developed by Canonical. It provides flexibility by offering a single process for multiple containers. It connects to the Linux container library (LXC) using a REST API. It is an add-on to LXC, providing more features and functionalities. - Source: dev.to / almost 2 years ago

LXD is a manager for Linux Containers (LXC), which lets me spin up a kind-of lightweight VM for any distro, instantly. I use it to run proprietary software isolated from the rest of my system (such as Steam); disposable environments for trying stuff out, and running software that doesn't jive well with Nixos.

Docker introduced container images to the technology world, making container images a standardized delivery unit. In fact, before Docker, containerization technology already existed. Let's talk about a more recent technology, LXC (Linux Containers) in 2008.

Linux containers (LXC) are the native containers available in Proxmox. These are quite a bit different than Docker containers. They behave and are managed more like "systems" with their own host name, IP address, shell, etc. TurnKey Linux builds and maintains a number of LXC templates that can be downloaded and installed for free.

Linux Containers (LXC) proffers a compelling alternative in the realm of containerization, particularly valued for its ability to offer a lightweight, efficient virtualization method that emphasizes system-level isolation without introducing the complexity and overhead typical of full virtual machines. In the context of cloud computing, virtualization, and IT automation, LXC stands as a significant player alongside more prolific contemporaries like Docker, Hyper-V, and vSphere.
A consistent thread in discussions about LXC is its positioning as an OS-level virtualization method, capable of executing multiple isolated Linux systems on a single host. The underlying Linux kernel is shared across containers, allowing for efficient resource utilization. Traditionally, LXC has been perceived as a more foundational, albeit less user-friendly, alternative compared to Docker, which dominated the containerization landscape by providing container images and integration with DockerHub, thus facilitating easier application deployment and management.
The advent of Docker shifted the perception of containerization, popularizing the notion through application packaging and image sharing, which admittedly LXC did not initially offer. However, with the introduction of LXDโan extension of LXC managed by Canonicalโthere has been a focused shift to enhance usability. LXD provides an improved user interface, akin to a virtual machine manager, reducing server overhead and expanding container management functionalities more aligned with familiar VM experiences.
Despite its efficiency, LXC does have certain limitations, notably the absence of direct Kubernetes integration and a lack of formal PCI compliance, both of which are critical in enterprises seeking comprehensive, compliant container solutions. However, ongoing developments, epitomized by efforts like LXRUN, aim to address these challenges, promising to bridge gaps where Docker currently holds advantages.
In terms of community engagement, LXC benefits from a robust and active user base. This community fosters continuous improvements and shares innovative uses of LXC and LXD, underscoring the system's adaptability across various technical environments. Strategic forums and community platforms serve as both support systems and idea-exchange hubs, indicative of LXCโs collaborative culture.
Functionally, LXC serves a niche where it shines as a means to create efficient, system-level containers that offer a virtual machine-like experience with lower overhead. Common use cases span testing environments, isolated proprietary software execution, and lightweight VM-like deployments on hardware constrained devices, like Raspberry Pi. Through its association with Proxmox, which natively supports LXC, it also finds application in environments where lightweight, system-centric isolation is prioritized.
Overall, while Docker may have popularized containerization, LXC continues to hold relevance by providing a robust, efficient alternative that appeals to users seeking system-level isolation and VM-like management without the complexity traditional virtualization solutions typically entail. Thus, LXC and its related advancements remain integral in both legacy and modern DevOps environments, facilitating versatile, innovative deployment solutions.
