Advanced Visualization

Advanced Visualization, also known as advanced visual representation, refers to interactive visual displays that assist in comprehending and communicating complex information and relationships. In contrast to simple dashboards, advanced visualizations offer the additional capability of interactively modifying the display, enabling a gradual analysis of various sub-questions. Furthermore, advanced visualizations typically incorporate coordinated multiple views, which allow interconnected aspects of the visualized data to be simultaneously presented and related to each other. external-link

Affective Computing

A computing device equipped with the ability to detect and suitably respond to user emotions and other stimuli is what we refer to as affective computing. This capacity enables the device to gather emotional cues from various sources such as facial expressions, posture, gestures, speech, keystrokes force or rhythm, and even temperature changes of the user's hand on the mouse. All of these cues can signify changes in the user's emotional state, which can then be detected and interpreted by the computer. To accomplish this, a built-in camera captures images of the user, and algorithms are used to process the data into meaningful information. Besides, affective computing applications are exploring technologies such as speech recognition and gesture recognition. external-link


Affinity in Kubernetes consists of rules that provide the scheduler with hints about pod placement. Node affinity and pod-to-pod affinity are the two types of affinity available. Rules are created using Kubernetes labels and selectors defined in pods, and they can be either required or preferred, depending on the level of enforcement desired. external-link

Aggregation Layer

The aggregation layer in Kubernetes allows the installation of additional Kubernetes-style APIs to the cluster. After configuring the API Server to support these APIs, APIService objects can be added to claim URL paths in the Kubernetes API. external-link


The Gaia-X European Association for Data and Cloud AISBL (french: association sans but lucrative) is a non-profit association that represents the members of Gaia-X and promotes international cooperation. It is developing the legal framework of Gaia-X and ensures the availability of necessary services. external-link

Analytics as A Service

AaaS is the delivery of analytical tools and services using web-based technologies, which enables companies to avoid investing in internal hardware infrastructure for their analytics needs. external-link

API Group

In Kubernetes, an API group is a collection of related paths in the API. Each group can be enabled or disabled by changing the API server's configuration. Specific resource paths can also be enabled or disabled. API groups simplify extending the Kubernetes API and are specified in REST paths and the apiVersion field of serialized objects. More information on API groups can be found in the documentation. external-link

API Proxy

An API proxy acts as a gateway between your developers and backend services, although its capabilities are limited compared to an API gateway. It is an intermediary that sends requests for developers and sits between the application and backend services. An API gateway provides additional features such as transmission limiting, security, and API monitoring. external-link

API-initiated eviction

API-initiated eviction in Kubernetes is when the Eviction API is used to create an Eviction object that triggers graceful pod termination, either through direct calls to the API or tools like kubectl drain. When the Eviction object is created, the API server terminates the Pod while respecting configured PodDisruptionBudgets and terminationGracePeriodSeconds. API-initiated eviction is distinct from node-pressure eviction. For more information, refer to the documentation. external-link

App Container

Application containers are the containers in a pod that start after any init containers have finished running. Init containers allow separation of initialization details that don't need to keep running after the application container has started. If there are no init containers configured, all containers in the pod are app containers. external-link

App Store

A reliable system for disseminating Data Applications with a variety of search capabilities, such as filtering by functional or non-functional attributes, pricing model, certification status, community evaluations, and more. external-link

Application Architect

An application architect is responsible for the high-level design of an application, ensuring that it interacts with surrounding components such as databases and logging infrastructure in a scalable and maintainable way. external-link

Application portability

The process involves moving executable code developed by customers or third parties from one public or private cloud service to another. external-link

Application Programming Interface

An interface for programming that makes it possible to represent modes of operation in an abstract way so that ICT systems can communicate with each other and access processes and resources without having to modify the code of the application programs directly. external-link

Architecture of Standards 

The Architecture of Standards (AoS) document establishes a goal for Gaia-X by reviewing and consolidating existing standards related to data, sovereignty, and infrastructure components, while also clarifying which standards are endorsed and supported by Gaia-X. external-link

Architecture Principle 

The Architecture Principles establish the fundamental guidelines governing the use and deployment of all IT resources and assets within the Gaia-X initiative. They are the result of a consensus among the various entities involved in the initiative and provide a framework for making future IT-related decisions. external-link

Artificial neural network

Artificial neural networks are statistical models that take inspiration from the workings of biological brains. They are made up of interconnected nodes arranged in multiple layers, with each node containing a function and each connection between nodes carrying a weight to be optimized using deep learning algorithms. The input that reaches a node's function via each connection is adjusted based on its weight. external-link
