Version 3 in progress

Why a Common Glossary

The EGI Community is composed by a large number of heterogenous actors who contribute to providing or consuming services for e-Science. Policy makers produce policies and procedures that govern the EGI processes; dissemination experts write articles for communicating the progress and results in using or evolving EGI; end-users write papers on research results achieved through the infrastructure; technology providers report on the advancement of technology components that enable EGI to operate and so on. From many parties, it has been often expressed the need to identify a common set of terms which definition is agreed and shared so to improve the understanding and consistency of documents. The goal of the EGI Glossary is to address this problem by identifying and maintaining a shared set of terms across all the functional areas of EGI in order to enable a consistent understanding and usage within a well-defined scope. The EGI Glossary is maintained by the EGI Glossary Coordination Group who collect feedback from the whole EGI community through the EGI policy boards.

Terms and Definitions


EGI Glossary
Term Abbr. Definition
AUP A set of terms and conditions applicable to the Users of an IT Infrastructure.
Property of information being accessible and usable by an authorised party
An entry in an accounting database identifying the quantitative usage of Resources by Users.
Set of actions carried out within a Process.
A predefined collection of software Products that are deployed together so that it appears as a single undividable Service or application that implements one or more IT Capabilities.
Set of actions to evaluate the level of Capability of a Process or the overall maturity of a Management System.
Systematic, independent and documented Process for obtaining Audit evidence and evaluating it objectively to determine the extent to which the audit criteria are fulfilled.
Note 1: Typical forms of audit evidence include documented information, information provided during an audit interview, and information gathered through observation.
Note 2: Audit criteria may be taken from or based on requirements from a management system (including policies, processes and procedures), agreements (including service level agreements and underpinning agreements), contracts, standards or legislation.
Note 3: An audit may be an internal audit, if it is conducted under the direct responsibility of the organisation or federation that is subject to the audit, or an external audit, if it is conducted by an external party.
Note 4: Both internal and external audits should be conducted by skilled and experienced auditors, and auditors should not audit their own work or areas of responsibilities to ensure the impartiality of the results.

Ability of a Service or service component to fulfil its intended function at a specific time or over a specific period of time.
The rationale of how an organisation creates, delivers, and captures Value. The Process of business model construction is part of business strategy. The term business model is used for a broad range of informal and formal descriptions to represent core aspects of a business, including purpose, offerings, strategies, infrastructure, organizational structures, trading practices, and operational processes and policies.
Achieved level of effectiveness of an individual process or general aspect of management
The maximum extent to which a certain element of the infrastructure (such as a Configuration Item) can be used.
Note: This might mean the total disk capacity or network bandwidth. It could also be the maximum ability of a system to process requests.
Alteration (such as addition, removal, modification, replacement) of a Configuration Item (CI) 
CRC A Resource Centre that conforms to the requirements specified in the Resource Centre Registration and Certification Procedure.

Assignment of items to defined groups based on common attributes, relations or other criteria

Note 1: Items that are subject to classification may include documents, records (such as incident records or change records), services, configuration items (CIs), etc. Defined groups may include categories (such as incident categories or change categories) or priority levels.

Note 2: The act of classification often comprises the application of more than one classification scheme. For instance, an incident record might be assigned to a technical incident category such as ‘software related’, ‘network related’, etc., and also to a priority level like ‘low priority’, ‘medium priority’, etc. The assignment of various incidents, service requests, changes and problems to an affected CI is also a classification.

Note 3: Besides the presentation and analysis of relationships, classification is often used as input for controlling the workflow of a process, e.g. by assigning a priority level to an incident.

Final activity in a workflow of a process to indicate no further action is required for a specific case

Note: Cases that are subject to closure may include incidents, problems, service requests or changes. The activity of closure puts the connected record (such as the incident record, problem record, service request record or change record) in its final status, usually called ‘closed’.

A model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction. This cloud model is composed of five essential characteristics (on-demand self-service, broad network access, resource pooling, rapid elasticity, measured service), three service models (Software as a Service or SaaS, Platform as a Service or PaaS, Infrastructure as a Service or IaaS), and four deployment models (private cloud, community cloud, public cloud, hybrid cloud).

HPC A computing paradigm that focuses on the efficient execution of compute intensive, tightly-coupled tasks. Given the high parallel communication requirements, the tasks are typically executed on low latency interconnects which makes it possible to share data very rapidly between a large numbers of processors working on the same problem. HPC systems are delivered through low latency clusters and supercomputers and are typically optimised to maximise the number of operations per seconds. The typical metrics are FLOPS, tasks/s, I/O rates.
HTC A computing paradigm that focuses on the efficient execution of a large number of loosely-coupled tasks. Given the minimal parallel communication requirements, the tasks can be executed on clusters or physically distributed resources using grid technologies. HTC systems are typically optimised to maximise the throughput over a long period of time and a typical metric is jobs per month or year.
