rendszertárolók

Rendszertárolók, often translated as system containers, are a type of lightweight operating system-level virtualization. Unlike traditional virtual machines that virtualize hardware, system containers virtualize the operating system. This means they share the host operating system's kernel, leading to faster startup times and significantly reduced resource overhead compared to full virtual machines.

The primary benefit of system containers is their efficiency. By sharing the host kernel, they consume less CPU and RAM. This allows for higher density, meaning more containers can be run on a single host compared to virtual machines. They are ideal for running multiple isolated services or applications on a single server while maintaining separation and security.

Common use cases for system containers include packaging and deploying applications, creating isolated development and testing environments, and running microservices. They provide a consistent runtime environment, ensuring that applications behave the same way regardless of the underlying infrastructure.

Examples of technologies that implement system containers include LXC (Linux Containers) and Docker, although Docker has evolved to also support application containers, which are even more lightweight. System containers are often compared to application containers, with system containers providing a more complete operating system environment within the container, including a full init system, while application containers typically focus on running a single application process. This distinction is important for understanding their respective strengths and use cases.
