The basic scheduling unit in Kubernetes is a pod, [54] which consists of one or more containers that are guaranteed to be co-located on the same node. [32] Each pod in Kubernetes is assigned a unique IP address within the cluster, allowing applications to use ports without the risk of conflict. [ 55 ]
A deployment diagram [1] "specifies constructs that can be used to define the execution architecture of systems and the assignment of software artifacts to system elements." [1] To describe a web site, for example, a deployment diagram would show what hardware components ("nodes") exist (e.g., a web server, an application server, and a database server), what software components ("artifacts ...
A sample network diagram Readily identifiable icons are used to depict common network appliances, e.g. routers, and the style of lines between them indicates the type of connection. Clouds are used to represent networks external to the one pictured for the purposes of depicting connections between internal and external devices, without ...
Network topology is the arrangement of the elements (links, nodes, etc.) of a communication network. [1] [2] Network topology can be used to define or describe the arrangement of various types of telecommunication networks, including command and control radio networks, [3] industrial fieldbusses and computer networks.
In telecommunications networks, a node (Latin: nodus, ‘knot’) is either a redistribution point or a communication endpoint. A physical network node is an electronic device that is attached to a network, and is capable of creating, receiving, or transmitting information over a communication channel . [ 1 ]
The PoD is a repeatable design pattern, and its components maximize the modularity, scalability, and manageability of data centers." [1] The modular design principle has been applied to telephone and data networks, for instance through a repeatable node design describing the configuration of equipment housed in point of presence facilities.
Example of a system context diagram. [1] A system context diagram in engineering is a diagram that defines the boundary between the system, or part of a system, and its environment, showing the entities that interact with it. [2] This diagram is a high level view of a system. It is similar to a block diagram.
A node [1] in the Unified Modeling Language (UML) is a computational resource upon which UML artifacts may be deployed for execution. [ 1 ] There are two types of nodes: device nodes and execution environments .
