The concept of cloud computing may be more abstract. In layman's terms, cloud computing is an upgraded version of the previous server computing network. Its main features are strong scalability, low price, high degree of virtualization and strong computing power. In general, the concept of cloud computing in cloud computing may be abstract. It mainly has several characteristics, such as strong scalability, low cost, virtualization, strong computing power and so on. Yunrong Technology tells you that services are divided into three levels: iaas, Paas and saas. At the same time, according to the service carrier, the service contents such as CAA, NaA and MAA are derived.

A brief Analysis of six Services of Cloud Computing

1.IaaS

The first layer of Infrastructure as a Service (Infrastructure-as-a-Service,Infrastructure-as-a-Service) is called IaaS.

A few years ago, if you wanted to run some enterprise applications on your office or company's website, you needed to buy a server or other high-cost hardware to control your local applications and get your business running.

But now with IaaS, you can outsource your hardware elsewhere. IaaS will provide off-site servers, storage and network hardware that you can rent. Save maintenance costs and office space, and companies can use this hardware to run their applications at any time.

2.PaaS

The second layer of platform as a service (platform as a service) is called PaaS. All the development of the company can be carried out at this level, saving time and resources.

Paas provides a variety of solutions for developing and distributing applications online, such as virtual servers and operating systems. This saves you money on hardware and makes it easier for you to work with distributed studios. Network application management, application design, application hosting, storage, security, and application development collaboration tools.

3.SaaS

The third layer of Software as a Service (Software-as-a-Service) is also known as SaaS. This layer is the one that comes into contact with your life every day, mainly through a web browser. Any application on a remote server can run on the network, which is called SaaS.

At present, the development of the three is good, and there is a close relationship between them. Among them, IaaS is the basic layer, PaaS is the platform layer and SaaS is the software layer.

4.CaaS

Communications-as-a-Service is a service (also known as collaboration as a service). CaaS encapsulates traditional telecommunications functions (such as messaging, voice, video, conferencing, and communication collaboration) into API (application programming interface) or SDK (software development kit). It is used by a third party to provide telecommunications functions as a service.

5.MaaS

Machine as a service is the Internet of things as a service. This concept is accompanied by the Internet of things. The two common business forms of the Internet of things are MAI and MAA, so MAA belongs to a form of business of the Internet of things.

6.NaaS

Naas (network as a service) network is a kind of service that provides different virtualized network services for various users through network virtualization, security device virtualization, sdn and other network technologies. Naas plays a vital role in modern cloud computing and acts as a bridge between various elements.

In the traditional IT network architecture, when the system is deployed or upgraded, it is very tedious and expensive to adjust the corresponding network equipment (router, switch, firewall) at the same time. This does not meet the stability and agility requirements of current applications. NaAS can solve these problems very well. Through the virtual network layer, users' applications and services can get rid of the shackles of the underlying hardware, and users can deploy network services such as IP-SEC, load balancing, IPS and so on quickly and cheaply.
