There are several definitions of cloud computing, but the National Institute of Standards and BIM Solution Technology's (NIST) is now the most frequently accepted: A shared pool of reconfigurable computing resources (including networks, servers, storage, applications, and services) is made available through the pay-per-use model of cloud computing. These resources can be quickly provisioned with little administrative work or contact with service providers. A common pool of reconfigurable computing resources—including networks, servers, storage, applications, and services—can be made available through the Big Data system and supplied fast, with minimum administrative labor or contact with service providers.

Technically speaking, Big Data and CDE solution Cloud Computing are entwined in the same way as opposite sides of a coin are. Big Data processing inevitably requires a distributed computing architecture as a single machine is unable to handle it. Although it requires rely on the distributed processing, distributed database, cloud storage, and virtualization capabilities of cloud computing, it is defined by the mining of vast amounts of data. Let's take a closer look at each of the three ideas that make up cloud computing and are derived from it: IaaS (Infrastructure as a Service), PaaS (Platform as a Service), and SaaS (Software as a Service). These three concepts represent the industry's widely accepted split of the three basic cloud computing service models.

1.Infrastructure as a Service (IaaS)

Through the Internet, customers may get services from the ideal computer infrastructure. Internet-based services (such storage and databases) are a part of this sort of service, which is referred to as IaaS.

2.Platform as a Service (PaaS)

Without needing to own development, QC, or production servers, PaaS (Platform as a Service) offers an architecture on which software developers may create new applications or expand already existing ones. Ronglian Cloud Communication is one company that uses the PaaS approach. It significantly lowers the barrier for businesses and developers to use communication services because Ronglian packages professional communication capabilities into API interfaces and SDKs. As a result, apps, websites, and enterprise systems can easily access more than 20 professional communication capabilities, including voice calls, voice notifications, voice intercom/conferencing, video calls/conferencing, and SMS/voice authentication codes. Conference and other 20 different professional communication capabilities, improved efficiency in development and use, and quick realization of the five functions of SMS/smart call, call, call center, mobile IM, conference, etc. are just a few of the ways that this company is devoted to making communication a fundamental Internet service.

3.Software as a Service (SaaS)

is a method of selling application software in which users pay according on the amount of time or use that particular program receives. This method is typically used to sell enterprise management software. Customer relationship management (CRM), human resource management (HRM), supply chain management (SCM), and other corporate management tools are typically seen to be the key applications for SaaS software. For instance, Ronglian is a SaaS cloud service provider with ten years of experience in the China call center industry. The company has independently researched and developed a cloud-based call center communication platform, combining the use of customer scenarios to provide cloud customer service, cloud telemarketing, cloud switchboards, cloud meetings, and other enterprise communication products. Platform users cover customer service seats, sales seats, and enterprise switchboard. Enterprise clients of the business are from a variety of sectors, including banking, education, the internet, business-to-business, the automotive industry, healthcare, and others.

4. Backend as a Service (BaaS)

Back-end as a service, or Baas in English and Chinese respectively, is an application architecture where the server logic and state are controlled by the service provider and a large number of third-party cloud servers and APIs are used. For instance, the front and back end interaction in our conventional single page application (SPA) and mobile rich client application is mostly built on RestAPI calls. To do the appropriate tasks, such as common authentication, cloud data/file storage, message push, application data analysis, and so on, you merely need to access the service provider's API.

5.What is Function as a Service (FaaS)?

Function as a Service is another name for FaaS. Developers simply need to create the business code; they do not need to be concerned about the server; and the execution of the code is triggered by the event. Developers may immediately deploy the service business logic code, operating in the stateless computing containers offered by third parties. The finest FaaS implementation right now is AWS Lambda.

6. There are none (ServerLess)

Combining BaaS and FaaS applications, serverless application architecture allows users to focus solely on applying business logic code, write functions for the granularity of their operations in the FaaS platform, and integrate BaaS third-party services to create a final system. The server requires zero attention from the system process as a whole.
