Three waves of changes in cloud computing

Cloud computing is an important part of digital infrastructure , It is the driving force for the development of digital economy , It plays an important role in China's industrial digital transformation and the improvement of the digital level of public services . In a broad sense , Cloud computing is that manufacturers build network server clusters , Provide online software services to various types of customers 、 Hardware rental 、 data storage 、 Different types of services such as computing and Analysis . The ultimate goal is to calculate 、 Services and applications are provided to the public as a public facility , So that people can use water 、 electric 、 Use computer resources like gas and telephone .

China's cloud computing market is in a stage of rapid development , Containers 、 The continuous maturity of microservices and other technologies , It is also constantly promoting the reform of Cloud Computing .

The initial operation mode of cloud computing is IaaS, Infrastructure as a service . The system supplier provides the user with calculation information 、 Storage 、 Network and other basic hardware resources , Users can pay by volume , rent IaaS The hardware resource environment deployed by the service provider , And deploy and run various software on these basic hardware facilities .IaaS Patterns have triggered traditional IT The shift to the cloud , Its users mainly focus on professional IT On personnel .

But with the completion of four rounds of iteration of microservice Architecture , The loose coupling function of the module is basically realized , Cloud computing is gradually changing from IaaS Transformed into SaaS, Software as a service , That is to provide software services through the network .SaaS Platform vendors deploy their application software on their own servers , Customers can work according to their actual needs , Order the required application software services from manufacturers through the Internet , Pay the manufacturer according to the number and length of service ordered , And get it through the Internet Saas Services provided by platform providers .

SaaS Although the rapid development of has only happened in recent ten years , But with the continuous influx of capital markets , Completion of multiple rounds of financing , To 2020 year ,SaaS The market size of has far exceeded IaaS.

The increasing number of users has brought more demand , And solving these growing personalized needs has become SaaS Development must cross a threshold . In this context ,PaaS There's a pattern .

PaaS Platform as a service , That is, the platform of software research and development is submitted to users as a service .PaaS Although the pattern appeared earlier , But limited to professional IT Developers are not on scale , Until the emergence of low code in recent years , Just let PaaS Officially into everyone's sight .

Low code is a software development method , Through visual drag and drop programming , With little or no need to write code, you can quickly develop applications , Realize rapid application development 、 A technology and tool for configuration and deployment . The emergence of low code , Let everyone be able to program , Everyone is a programmer , Everyone can be PaaS Users of .

Traditional functional requirements , Need research , Drawing prototype , Development , test , go online , Each link involves different professionals , The development cycle is usually the shortest and usually takes a few weeks . Low code allows the demand side to program itself , Realize the logic by yourself , It usually takes a few hours to complete the function .

Efficient development based on business logic and the characteristics of connecting heterogeneous environment data , Let low code based PaaS The platform has become the rigid demand of enterprise digital transformation . Low code based PaaS The platform can develop interfaces , Quickly integrate internal and external data of the enterprise , Realize data unification . And meet the customized development needs of enterprises , Give full play to the potential of internal personnel , Let all enterprise employees become programmers , It can also be further integrated with artificial intelligence 、 big data 、 Combination of blockchain capabilities , Further empower the enterprise .

so to speak , With the blessing of low code ,PaaS Will change from a sunny spring to a mass tool , Which leads to fusion , Make cloud computing more inclusive .
