Service-to-service (S2S), the fourth service model, and four categories of cloud computing

Cloud computing was viewed as an impenetrable technology by China's IT community more than ten years ago, but thanks to Aliyun's successful growth, cloud computing has taken off in all of BIM Solution China's behemoths. Nowadays, cloud computing is utilized by everyone, whether they are customers, businesses, or the government. Private, public, hybrid, and multi-cloud computing are the four basic subtypes of cloud computing. In the meantime, there are currently three main types of cloud computing service models: infrastructure as a service (IaaS), platform as a service (PaaS), and software as a service (SaaS). As technology advances, cloud computing will eventually be developed into a fourth mode, called service to service (S2S). Following extensive investigation, Dr. Liangjie Zhang, Distinguished Scientist of the American Computer Society and Fellow of the International Institute of Electrical and Electronics Engineers (IEEE Fellew), proposes the concept.

Models for Cloud Computing Deployment

Free Cloud

All of the components of cloud-based apps are completely installed in the cloud and CDE solution operate there. Applications in the cloud fall into two categories: those that are built there and those that are moved there from an on-premises architecture to benefit from cloud computing. In order to abstract from the administration, architectural, and scalability needs of the underlying infrastructure, cloud-based applications can be built on infrastructure components or on top of higher-level services.

Blended Cloud

An strategy to integrating infrastructure and applications between current cloud-based and non-cloud resources is hybrid deployment. The most typical hybrid deployment strategy entails connecting cloud resources to internal systems while extending an organization's infrastructure into the cloud and combining it with the local infrastructure already in place.

Personal Cloud

The term "private cloud" is frequently used to describe local resource deployment utilizing virtualization and resource management techniques. Although local installations may not provide many of the advantages of cloud computing, they are occasionally utilized to make it possible to provide specialized resources. This deployment approach is mostly analogous to an outdated IT infrastructure, including strategies for application management and virtualization to optimize resource usage.

Multi-Cloud

A multi-cloud is a type of cloud architecture that combines different cloud services from different public and private cloud providers. While all multi-clouds are hybrid clouds, not all hybrid clouds are multi-clouds. When many clouds are linked together using some kind of integration or orchestration, a multi-cloud turns into a hybrid cloud.

Multi-cloud setups may be created on purpose (to increase control over sensitive data or as redundant storage for better disaster recovery) or unintentionally (typically as a result of shadow IT). In either case, it demonstrates that an increasing number of businesses are choosing multi-cloud in an effort to scale up their environments' security and performance.

Models for Cloud Computing Services

Currently, there are three primary cloud computing models, or service models: laaS, paaS, and saaS. The cloud computing stack is represented by each model as a separate component. The fourth service-to-service (S2S) paradigm will become more prevalent in the future.

1. IaaS, or infrastructure as a service

IaaS, commonly referred to as infrastructure-as-a-service, refers to the fundamental components of cloud computing that generally give users access to networking capabilities, computers (virtual or dedicated hardware), and data storage space. The most flexibility and administrative control over IT resources is provided by infrastructure-as-a-service, which uses techniques that are most similar to already-existing IT resources that many modern IT departments and developers are accustomed to.

The actual servers, networks, virtualization, and data storage are all part of IaaS. Users can access the infrastructure through control panels or APIs and effectively rent it. While the provider manages the hardware, network, hard drives, data storage, servers, outages, maintenance, and hardware issues, the user is in charge of managing components like the operating system, apps, and middleware. This deployment strategy is popular for cloud storage providers.

2. PaaS (Platform as a Service)

Platform-as-a-Your business may concentrate more on the deployment and administration of your applications by outsourcing the management of the underlying infrastructure (usually hardware and operating systems) to a service provider. Because you don't have to worry about resource purchase, capacity planning, software maintenance, patch installation, or any other undifferentiated grunt labor related to operating applications, this helps to boost efficiency.

The user will be in charge of the apps that operate on the platform and the data that the programs depend on, while an external cloud service provider will provide and maintain the hardware and application software platform on PaaS.Designed to give users access to a shared cloud platform for application development and administration (a crucial element of DevOps), PaaS is intended for developers and programmers and eliminates the need for creating and maintaining the infrastructure typically involved with the process.

3. SaaS (Software as a Service)

Software-as-a-A service provider manages and operates a whole product as part of the service. Applications that are utilized by end users are frequently referred to as "software as a service." With a SaaS product, you just need to consider how to utilize the SaaS software; service upkeep and infrastructure administration are taken care of for you.

SaaS is a service that gives consumers access to software applications that are controlled by a cloud service provider. A SaaS application is often an online or mobile program that is accessed via a web browser. The user connects to the cloud application using a control panel or API, and the service handles software upgrades, bug patches, and other normal software maintenance for them. SaaS also eliminates the requirement for users to locally install apps on their computers, giving groups or teams more access points to the software.

4, S2S (service to service)

Cloud computing will develop into a fourth form as new technologies flourish and as technology continues to advance, creating the opportunity for the S2S Service-to-Service (S2S) paradigm. Without needing to consider the cloud, S2S may travel directly to the user, rendering the cloud useless.

Following extensive investigation, Dr. Liangjie Zhang, Distinguished Scientist of the American Computer Society and Fellow of the International Institute of Electrical and Electronics Engineers (IEEE Fellew), proposes the concept.

Currently, ABCD may be used to depict the technological frontier:

AI, Blockchain, Cloud Computing, Big Data, and the Internet of Everything are all examples of A.

Cloud computing will eventually become a need for our whole IT infrastructure, which is not a surprise. The ultimate service model for cloud computing as an infrastructure is service-to-service (S2S) based on the cloud.

Additionally, it will be a cutting-edge technology advancement on a worldwide scale.
