Cloud computing refers to the delivery of hosted services over the internet This broad term encompasses three primary categories: Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS) (Wesley Chai, Stephen J Bigelow, 2022) There are two types of cloud environments: public and private Public clouds offer their services to the general public over the internet, whereas private clouds provide hosted services to a select group of users with specific access and permission settings Regardless of being private or public, the aim of cloud computing is to offer convenient and scalable access to computing resources and IT services The infrastructure of cloud computing includes both the physical hardware and software components necessary for the implementation of a cloud computing model This model can also be referred to as utility computing or on-demand computing The term "cloud computing" was coined from the cloud symbol frequently used to represent the internet in flowcharts and diagrams II Client – server The client-server model is a structure used in distributed applications, where responsibilities are split between two main categories: servers, which provide resources or services, and clients, which request those services In this framework, when a client computer sends a data request to a server via the internet, the server receives, processes the request, and returns the requested data packets to the client It's crucial to note that clients in this setup not engage in resource sharing Common examples of the client-server model include email and the World Wide Web (syedmodassirali, 2022) Figure 2: Client-server model (syedmodassirali, 2022) Page of 59 Client Clients, which can also be referred to as service requesters, are either computer hardware components or software applications on a server that request resources and services offered by a server Client computing falls into three categories: Thick, Thin, or Hybrid (heavy, 2022) • • • Thick Client: This type of client offers extensive functionality, handles most of the data processing independently, and places relatively light demands on the server Thin Client: A thin-client server is a lightweight computer that heavily depends on the host computer's resources In this setup, an application server takes care of the majority of necessary data processing Hybrid Client: A hybrid client combines characteristics of both thin and thick clients It relies on the server to store persistent data but has the capability for local processing as well Server A server is a device or computer program that offers functionality to other devices or programs It encompasses any computerized process that can be utilized or called upon by a client to provide resources and distribute tasks (heavy, 2022) Some typical examples of servers include: • Application Server: It hosts web applications that users on the network can access without needing their individual copies • Computing Server: This server shares a significant amount of computer resources with networked computers that require more CPU power and RAM than what is typically available on a personal computer Page of 59 • • Database Server: It manages and provides databases for any computer program that processes well-organized data, such as accounting software and spreadsheets Web Server: This server hosts web pages and facilitates the functioning of the World Wide Web Relationship between Client and Server In the client-server model, which is crucial for contemporary networked computing, the connection between client and server is marked by a reciprocal and synergistic interaction Both clients and servers assume specific, yet complementary roles, collaboratively ensuring the seamless exchange of data and services within a network (Contributor, 2023) Characteristics of the Client-Server Relationship: • The flow of digital data operates under a distinctive client-server model Imagine a client, akin to your smartphone, that doesn't need to store every app and file Instead, it interacts with a centralized server, akin to a well-stocked digital library, using a specific protocol This protocol facilitates efficient data transfer and communication, functioning similarly to a universal language (Joshjnunez, 2020) • When the client requests a certain app or file, the server awaits this request Upon its arrival, the server verifies the identity of the client before granting access Once verified, the server promptly dispatches the requested item, be it a document, video, or software, to the client • This process usually takes place over a network, which could be the vast internet or a private digital pathway This synchronized, service-like communication is governed by protocols like TCP/IP TCP acts as a vigilant server, ensuring a smooth transition from the initial request to the final delivery, comparable to waiting in a restaurant for your meal to be served In contrast, IP functions like an independent courier, dispatching separate data packets, each carrying a part of the overall information, similar to how different letters in a message convey various parts of the content • Through their collaborative efforts, the client-server architecture enables access to a wide array of digital resources, transforming the way information is stored and retrieved from a solitary task to a dynamic exchange between multiple entities Types of Client-Server Relationships: • Client-server relationships can vary depending on the architecture and the specific needs of the network or application Here are some common types of client-server relationships: • One-to-One (1:1): In this type, a single client communicates with a single server It's often seen in situations where highly specialized or secure communications are necessary Page 10 of 59
