Docker Compose is a tool for defining and running multi-container Docker applications. [29] It uses YAML files to configure the application's services and performs the creation and start-up process of all the containers with a single command.
Singularity is a free and open-source computer program that performs operating-system-level virtualization also known as containerization. [4]One of the main uses of Singularity is to bring containers and reproducibility to scientific computing and the high-performance computing (HPC) world.
The Yellowdog Updater Modified (YUM) is a free and open-source command-line package-management utility for computers running the Linux operating system using the RPM Package Manager.

In computer networking, linear network coding is a program in which intermediate nodes transmit data from source nodes to sink nodes by means of linear combinations.. Linear network coding may be used to improve a network's throughput, efficiency, and scalability, as well as reducing attacks and eavesdropping.
For example, a PID namespace provides a separate enumeration of process identifiers within each namespace. Also available are mount, user, UTS (Unix Time Sharing), network and SysV IPC namespaces. The PID namespace provides isolation for the allocation of process identifiers (PIDs), lists of processes and their details. While the new namespace ...
Active networking is a communication pattern that allows packets flowing through a telecommunications network to dynamically modify the operation of the network.. Active network architecture is composed of execution environments (similar to a unix shell that can execute active packets), a node operating system capable of supporting one or more execution environments.
For example, if a process has administrative permission to change the IP address of a network interface, it may do so as long as its own user namespace is the same as (or ancestor of) the user namespace that owns the network namespace. Hence, the initial user namespace has administrative control over all namespace types in the system. [11]
