Secret
Secrets are used to securely store confidential data such as passwords, OAuth tokens, and SSH keys in a Kubernetes cluster. By utilizing Secrets, you can exercise more control over how sensitive data is used and minimize the risk of accidental disclosure. By default, Secret values are encoded as base64 strings and stored unencrypted, but it's possible to configure Secrets to be encrypted when at rest. Pods can reference a Secret in various ways, including as an environment variable or a volume mount. It's worth noting that Secrets are intended for confidential data, while ConfigMaps are better suited for non-confidential data.

Selector
Selectors in Kubernetes enable users to filter a list of resources based on their labels. By applying selectors, it's possible to retrieve a subset of resources from a larger set of resources that match specific label criteria. Selectors are utilized when querying lists of resources to filter them based on their associated labels.

Self-Description
Gaia-X Self-Descriptions (SD) provide a machine-readable format for describing Entities based on the Gaia-X Conceptual Model. These SDs are presented in JSON-LD format and conform to W3C Verifiable Presentations standards. SDs consist of one or multiple Verifiable Credentials, which can be signed or unsigned arrays of information.
https://gaia-x.gitlab.io/glossary/
Self-Description Taxonomy
The entities identified within Gaia-X are defined by the Self-Description Schema, which establishes an inheritance structure. Each entity inherits characteristics from a single entity in the Conceptual Model, resulting in an inheritance hierarchy known as the Self-Description Taxonomy.

Self-Sovereign Identity (SSI)
Self-sovereign identity (SSI) enables individuals to locally manage and possess their digital identities and other verifiable digital credentials. The usage of a dominant cloud service provider is not mandatory, nor is the creation of a central Gaia-X Identity provider. This grants users complete autonomy from third parties, empowering them to determine which identity information to share with others. All identity data is kept securely in the user's SSI wallet, ensuring that it is exclusively accessible by the individual.predominant cloud service provider, nor is the establishment of a central Gaia-X Identity provider necessary. Users are thus completely independent of third parties and decide themselves which identity data they share with whom, as all identity data is securely stored only with the individual user in their SSI wallet.

Service Catalog
In the past, there was an extension API designed to facilitate the use of externally managed software services within Kubernetes clusters. These services could include offerings such as cloud providers' datastore services. With this API, applications could list, provision, and bind with these external managed services without requiring in-depth knowledge about the services' creation or management processes

Service Composition
Service Composition refers to the capability of a Service Offering to specify and require the existence of functional dependencies. These functional dependencies describe behaviors that respond to external actions, matching the requirements and characteristics of the Service Offering. Within the Gaia-X conceptual model, the functional dependencies of a Service Offering can include Resources, Assets, or other Service Offerings.

Service Instance
A Service Instance is an instance of a Service Offering that is created and running during runtime, and is closely tied to a specific version of a Self-Description. Each Service Instance has a distinct identity and can consist of one or more atomic building blocks that are uniquely identifiable and associated with a Service Subscription.
https://www.gxfs.eu/de/glossar/
Service Subscription
A Service Subscription is a contract between a Consumer and a Provider that enables and governs the use of one or more Service Instances. It is associated with a particular version of a Service Offering, which defines the attributes of the Service Instances that will be provided. The Service Subscription has a unique lifecycle separate from the Service Offering, and includes additional characteristics and rules.

Service/Data Catalogue
A catalog of IT services is a comprehensive list of technology resources and offerings provided by the IT service provider within an organization. Its purpose is to facilitate the efficient and effective management of these services, while also meeting the expectations of end-users.

Shapes Constraint Language (SHACL)
SHACL provides a language for validating RDF graphs based on a set of conditions expressed as shapes and other constructs in RDF form. In this process, the RDF graph that contains the shapes is called the shapes graph, while the one being validated is called the data graph. By validating data graphs against shapes graphs, SHACL allows for the creation of descriptions of data graphs that meet specific conditions, which can be useful for purposes such as building user interfaces, generating code, and integrating data.

Shuffle-sharding
In order to avoid overcrowding low-intensity request flows with high-intensity ones, a technique called shuffle-sharding can be used to assign requests to queues with better isolation than simple hashing modulo the number of queues. The latter method hashes certain request characteristics, such as the 5-tuple of source and destination address, protocol, and source and destination port, and assigns requests to the resulting queue. However, all low-intensity flows that hash to the same queue will be crowded out by any high-intensity flow that is assigned to it. Shuffle-sharding, on the other hand, uses the metaphor of shuffling a deck of cards and dealing a hand to assign requests to queues. After hashing the request characteristics to produce a hash value with many bits, the hash value is used as a source of entropy to shuffle the deck and deal a hand of queues. The request is then assigned to one of the examined queues with the shortest length. With a modest hand size, it is not expensive to examine all the dealt queues and low-intensity flows have a better chance of avoiding the effects of high-intensity flows. However, with a large hand size, examining the dealt queues is costly and it becomes more difficult for low-intensity flows to dodge the collective effects of high-intensity flows. Therefore, the hand size should be chosen carefully to achieve optimal insulation

SIG (special interest group)
Within the larger Kubernetes open source project, Special Interest Groups (SIGs) are communities of members who collectively manage a particular ongoing piece or aspect of the project. Each SIG has a shared interest in advancing a specific area, such as architecture, API machinery, or documentation. While SIGs are required to follow the SIG governance guidelines, they can establish their own contribution policy and communication channels as needed. For more information on Kubernetes SIGs and Working Groups, please refer to the kubernetes/community repository and the current list of SIGs and Working Groups

Storage Class
A Storage Class is a Kubernetes object that enables administrators to define and describe different types of available storage for use in the cluster. Storage Classes can be used to map storage types to various policies, such as quality-of-service levels or backup policies, that are determined by cluster administrators. Each Storage Class includes three key fields: provisioner, parameters, and reclaimPolicy. These fields are used when a Persistent Volume associated with the class is dynamically provisioned. Users can request a specific Storage Class by specifying its name.
