podman.io In computing , Podman ( pod manager ) is an open source Open Container Initiative (OCI)-compliant [ 2 ] container management tool from Red Hat used for handling containers, images , volumes , and pods on the Linux operating system , [ 3 ] with support for Mac OS and Microsoft Windows via a virtual machine .

OS-level virtualization is an operating system (OS) virtualization paradigm in which the kernel allows the existence of multiple isolated user space instances, including containers (LXC, Solaris Containers, AIX WPARs, HP-UX SRP Containers, Docker, Podman), zones (Solaris Containers), virtual private servers (), partitions, virtual environments (VEs), virtual kernels (DragonFly BSD), and jails ...
In computer science, interprocess communication (IPC) is the sharing of data between running processes in a computer system. Mechanisms for IPC may be provided by an operating system . Applications which use IPC are often categorized as clients and servers , where the client requests data and the server responds to client requests. [ 1 ]
Examples of Type-1 hypervisor include Hyper-V, Xen and VMware ESXi. Type-2 or hosted hypervisors These hypervisors run on a conventional operating system (OS) just as other computer programs do. A virtual machine monitor runs as a process on the host, such as VirtualBox. Type-2 hypervisors abstract guest operating systems from the host ...
System libraries, applications, virtualized /proc and /sys, virtualized locks, etc. Users and groups Each container has its own root user, as well as other users and groups. Process tree A container only sees its own processes (starting from init). PIDs are virtualized, so that the init PID is 1 as it should be. Network
Transparent Inter Process Communication (TIPC) is an inter-process communication (IPC) service in Linux designed for cluster-wide operation. It is sometimes presented as Cluster Domain Sockets , in contrast to the well-known Unix Domain Socket service; the latter working only on a single kernel.
The useful work that can be done with any computer depends on many factors besides the processor speed. These factors include the instruction set architecture, the processor's microarchitecture, and the computer system organization (such as the design of the disk storage system and the capabilities and performance of other attached devices), the efficiency of the operating system, and the high ...
D-Bus (short for "Desktop Bus" [4]) is a message-oriented middleware mechanism that allows communication between multiple processes running concurrently on the same machine. [5] [6] D-Bus was developed as part of the freedesktop.org project, initiated by GNOME developer Havoc Pennington to standardize services provided by Linux desktop environments such as GNOME and KDE.
