application hosting environment. See OTP application hosting environment

bare metal computer system

A physical or virtualized computer system on which no operating system has been installed. Application deployment onto a bare metal computer system is not possible until an operating system has been installed or deployed onto the system. physical domain and virtual domains are also bare metal computer systems.

capability

The ability and operational capacity to perform a particular function; a behavioral contract. Capability can be intrinsic, such as a specific OS version or processor architecture; or capability can be behavioral such as system failover or accounting.

cluster

• A computer system composed of two or more computer system that operate together as a functional whole to provide higher levels of application performance, resources, and reliability, availability, and service ability (RAS) characteristics than those provided by individual component computer systems. A cluster requires control software such as a cluster controller, which functionally complements the operating system installed on its constituent computer systems, and implements cluster-wide resource management functionality and policies.

• A virtualized application hosting environment that enables the highest possible levels of application availability.

clustered OTP system

An OTP system which is cluster of two more OTP Systems.

compute element

See computer system

computer system

• An element that is comprised of a collection of interoperating physical element, logical element, and software element that provide compute capabilities based on an operating system. See also bare metal computer system.

device

A logical element that provides access to, or control of, the capabilities of one or more physical element.

domain

A virtual bare metal computer system. See also logical domain and physical domain.

element

Hardware components such as processors, disk drives, or devices; also known as physical element.

Software components such as operating system or applications, also known as logical elements.

An entity that supports well-defined capabilities of use to other element.

grid

• A computer system composed of two or more computer systems that operate together as a functional whole to provide higher levels of application performance, resource and reliability, availability, and service ability (RAS) characteristics than those provided by individual component computer systems. A grid requires control software such as a grid controller, which functionally complements the operating system installed on its constituent computer systems, and implements grid-wide resource management functionality and policies.

host

• A computer system on which an operating system has been installed or deployed. The (potential) target of an Application Deployment.

• A computer system on which an application can be deployed.

hypervisor

Control software that supports the management of a virtual bare metal computer system. Synonymous with a Virtual Machine Monitor (VMM).

logical domain

A bare metal computer system composed entirely of virtual compute element, network element, and storage element that map to an equivalent or lesser set of element in a physical computer system. A logical domain can host a distinct operating system instance. Logical domains require the presence of underlying control software such as hypervisor.

logical element

An element not associated directly with a physical element. A logical element that provides access to capabilities of a particular physical element is a device. Logical Elements can also expose capabilities and functions that are not intrinsically mappable to a physical element, for example, services.

network element

A device capable of transmitting network packets across network endpoints.

network equipment provider (NEP) application hosting

The act of deploying and managing the life cycle and availability of applications developed by a network equipment provider (NEP) in the OTP application hosting environment

operating system

Control software that can be deployed to a bare metal computer system. An operating system manages access to the capabilities of its hosting computer system and may expose underlying logical element. Application deployment depends on the presence of an active operating system.

OTP

The Open Telecommunications Platform, which provides high availability, system management and application provisioning services that are integrated to create a base computing platform suitable for hosting, developing, and deploying telephone company applications.

OTP application hosting environment

The software element used for development and hosting of network equipment provider (NEP) applications, comprised of other software elements including platform management software, an application management framework, availability management framework, and the application runtime environment.

OTP application hosting environment software component

One of the software element comprising the OTP application hosting environment (AHE) software element.

OTP application run time environment

A set of programmatic interfaces exposed by the OTP application hosting environment software element for the purpose of development and runtime operation of hosted network equipment provider (NEP) applications.

OTP platform

A bare metal computer system designated for development and hosting of network equipment provider (NEP) applications An OTP platform can be a physical or virtual system.

OTP system

A computer system capable of hosting network equipment provider applications, comprised of an OTP platform, a deployed operating system instance and OTP application hosting environment software component.

physical domain

A bare metal computer system composed of compute element, network element, and storage element that map to a subset of the element in a particular physical computer system. A physical domain can host a distinct operating system instance. Physical domains require the presence of underlying control software such as hypervisor.

physical element

An element with a distinct physical existence that can be seen or touched. Physical elements occupy space and may consume power and generate heat.

software element

A piece of software that can be deployed onto a computer system. Examples include operating system, firmware, patches and application packages and images.

Solaris container

A virtualized host that isolates applications from one another by providing a virtualized operating system to each application. A Solaris container requires the presence of control software such as Global Zone to implements management functionality and policies.

storage element

A device capable of persistent storage of data. For example, disk drives and disk volumes such as network-attached storage (NAS) and storage area networks (SAN) devices.

virtual computer system

A computer system that is composed of partitioned or virtualized (mapped) element. See also logical domain and physical domain.

virtualized operating platform

See cluster, grid, Solaris container, and zone.

zone

See Solaris container.
