DeltaCloud is used in applications such as Aeolus to prevent the need to implement Cloud-specific logic. Fig. 10.2 shows DeltaCloud betweem HTTP client and IaaS Cloud providers. Client-server is a relationship in which one program (the client) requests a service or resource from another program (the server). The DeltaCloud API is designed as a RESTful web service and comes with client libraries for all major programming languages. Additional drivers for accessing further public or private Clouds can be created with minimal effort.

client synonymous with customer or a computer system or process that requests a service of another computer system or process (e.g., a server). In the client-server model, the client is a process that remotely accesses resources of a server. In the object oriented model, a class is considered a client of another class when it uses the other class features. According to C++ syntax, the clients can be grouped into is-a, has-a (or is-part-of), and use-a (or is-referred-by) relationships.
Network-Based Interaction
Published in Julie A. Jacko, The Human–Computer Interaction Handbook, 2012
Traditional Internet and web applications tended to work through client–server paradigms where a user’s client application accesses a well-known such as a web server. However, there has been a growth of more decentralized models at both higher and lower protocol levels (Androutsellis-Theotokis and Spinellis 2004).

The selected DBE articles were also reviewed in terms of architectural design. Various architectural patterns, such as client-server, peer-to-peer (P2P), service-oriented architecture (SOA), layered, cloud, publish-subscribe (Pub/Sub), Representational State Transfer (REST), hub-and-spoke, and fog-based, reported either singly or combined in 32 DBE architecture articles. The client-server architecture, also known as a two-tier architecture application, involves a server application that is reached directly by multiple clients, receives client request and respond to the clients (Javed et al., 2020). Multitier (n-Tier) architecture, is a client-server architecture that functions are separated more than two tiers (Figay et al., 2012). In a P2P architecture, every participating system can play the client as well as the server role, the roles can be changed dynamically so that it does not depend on the central server (Kim & Kim, 2018). SOA integrates software components that have been separately deployed, and traditionally has an integration strategy based on the enterprise service bus (ESB) technology for communication among software applications in different modules (Appio et al., 2018; Kuk & Janssen, 2013; Reforgiato Recupero et al., 2016).
Modelling and temporal evaluation of networked control systems using timed automata with guards and (max,+) algebra
Published in International Journal of Systems Science, 2018
The client/server network architecture (Figure 1) is a distributed application structure that parts workloads between the servers, i.e. the providers of a service, and the clients, i.e. the service requesters. Generally, PLCs are considered in NCS as clients and Remote I/O Modules (RIOM) as servers. The components of the NCS communicate over a computer network. Figure 2 shows an NCS working under client/server protocol. The representation at the data exchange zones in Figure 2 (memory and FIFO stack) is such that the arrows arriving above or below the exchange zone correspond to the event triggering the transfer while the arrows connected to the right or left sides correspond to the actual transfer of data.
