Serial, I2C, USB, CAN und Ethernet

Interfaces with serial communication enable data exchange between computers and peripheral devices or components. These interfaces are characterized by the transmission of data in bit sequences. However, different synchronization methods between the sender and receiver, as well as access procedures to the transmission medium, are used. Furthermore, these interfaces differ in their application area: CAN, for example, was developed for automotive applications, while Ethernet is used for LAN applications. external-link


In Kubernetes, a Service is a way to expose a network application that is running as one or more Pods in your cluster. A Service selects a set of Pods using a selector, and if more Pods are added or removed, the set of Pods that matches the selector will automatically change. The Service abstraction ensures that network traffic can be directed to the current set of Pods for the workload. Kubernetes Services utilize IP networking (IPv4, IPv6, or both) or a DNS external name. The Service abstraction also enables other mechanisms, such as Ingress and Gateway, to be employed. external-link

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. external-link

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. external-link

Service Offering

A Service Offering refers to a collection of assets and resources that a Provider combines into a package to offer to Consumers. The Service Offering may include nested offerings with one or more additional Service Offerings included within it. external-link

Service Set Identifier

An individually selectable name for a service set that identifies a device in the WLAN. A wireless access point can usually support multiple SSIDs simultaneously, allowing the setup of multiple virtual local area networks. A common scenario is the provision of a guest WLAN alongside at least one other WLAN. external-link

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. external-link

Service-oriented Architecture

SOA (Service-Oriented Architecture) is a concept or approach for organizing and utilizing distributed functions that are managed by different owners.

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. external-link


Sharding is a database partitioning technique that divides extensive databases into smaller, more manageable portions known as data shards. By breaking down the database into these smaller components, they become faster and easier to handle. The term "shard" refers to a diminutive fraction of the entire database. external-link

Sun (Oracle) has developed the Unix operating system Solaris. external-link

Stateful Set

A StatefulSet is responsible for managing the deployment and scaling of a set of Pods, while also ensuring the uniqueness and ordering of these Pods. Similar to a Deployment, a StatefulSet manages Pods based on an identical container spec. However, unlike a Deployment, each Pod in a StatefulSet maintains a persistent identity, meaning that these Pods are not interchangeable. If your workload requires storage volumes for persistence, you can use a StatefulSet as part of the solution. Although individual Pods in a StatefulSet are susceptible to failure, the persistent identifiers assigned to each Pod make it easier to match the new Pods to any existing volumes when replacing failed Pods. external-link

Supply Chain Management System

Supply Chain Management refers to the management of business processes within the supply chain from raw material suppliers to end consumers. To maximize the efficiency and cost-effectiveness of this supply chain, close collaboration between the involved companies is required. This collaboration is intended to enable optimal design of material, information, and financial flows both within and between the involved companies.
