The type_traits library in the C++ Standard Library provides a template named is_pod that can be used to determine whether a given type is a POD. [5] In C++20 the notion of “plain old data” (POD) and by that is_pod is deprecated and replaced with the concept of “trivial” and “standard-layout” types. [6]
A point of delivery, or PoD, is "a module of network, compute, storage, and application components that work together to deliver networking services.The PoD is a repeatable design pattern, and its components maximize the modularity, scalability, and manageability of data centers."
Container clusters need to be managed. This includes functionality to create a cluster, to upgrade the software or repair it, balance the load between existing instances, scale by starting or stopping instances to adapt to the number of users, to log activities and monitor produced logs or the application itself by querying sensors.
Containers emerged as a way to make software portable. The container contains all the packages needed to run a service. The provided file system makes containers extremely portable and easy to use in development. A container can be moved from development to test or production with no or relatively few configuration changes.
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 main classes of Docker objects are images, containers, and services. [22] A Docker container is a standardized, encapsulated environment that runs applications. [25] A container is managed using the Docker API or CLI. [22] A Docker image is a read-only template used to build containers. Images are used to store and ship applications. [22]
It has been developed and maintained by the PODS Association since 1998. [1] It provides pipeline operators with a database architecture for storing critical information and analysis data about their pipeline systems, and allows them to manage this data geospatially for visualization in GIS platforms.
The Solaris operating system provides man pages for Solaris Containers by default; more detailed documentation can be found at various on-line technical resources. The first published document and hands-on reference for Solaris Zones was written in February 2004 by Dennis Clarke at Blastwave, providing the essentials to getting started.
