Five minutes, Xie Yunyuan

In recent years , The concept of cloud native technology continues to heat up , It is becoming the focus of the Internet industry . Cloud primitives, with their powerful advantages, have triggered a IT Changes in infrastructure , More and more enterprises are willing to move the technology architecture towards “ Cloud native ” evolution . Digital China is no exception , It will be held in August this year “ Tech Digital China 2021 Annual Technology Conference ” On , Digital China grandly released the technology strategy related to cloud nativity . So bring this IT Where is the original cloud of change ？ Let's go to cloud primordial , Uncovering its mystery .

The evolving definition of cloud primordial

Cloud primordial is a Continuous development and evolution The concept of , At different times 、 Different organizations have different understandings and interpretations of cloud primordial . The debate about what cloud primordial is is still going on , At present, the cloud native Computing Foundation with extensive influence in the industry CNCF This is the definition of cloud primitiveness ：

Cloud native technology helps organizations in the public cloud 、 In new dynamic environments such as private and hybrid clouds , Build and run scalable applications , Representative technologies of cloud Nativity include containers , Service Grid 、 Microservices 、 Immutable infrastructure and declarative API. These technologies can build good fault tolerance 、 A loosely coupled system that is easy to manage and easy to observe . Combined with reliable automation means , Cloud native technology enables engineers to easily make frequent and predictable major changes to the system .
Cloud native Computing Foundation （CNCF） Committed to fostering and maintaining a vendor neutral open source ecosystem , To promote cloud native technology . By democratizing the most cutting-edge model , Let these innovations be used by the public .

CNCF Think cloud primordial is A general term for technologies such as building applications . Through cloud native technology, we can build elastic and extensible applications , These applications can be run in different environments , For example, private cloud 、 Public cloud 、 New dynamic environments such as hybrid clouds .

So what technologies are included in cloud primitives ？ It contains some popular and new technologies in our industry , Like containers 、 Microservices 、 Service Grid 、DevOps、 Cloud, etc. .

What kind of application does cloud native build ？ Applications built through cloud native technology are called cloud native applications , The coupling of its underlying infrastructure is relatively light , So it's easy to migrate , It can take full advantage of the capabilities provided by the cloud , So its development 、 Deploy 、 Management is more efficient and convenient than traditional applications .

The six elements of cloud primordial

The original ecology of cloud is very prosperous , The technology stack involved is huge and complex .CNCF Cloud native technology panorama collected tools related to cloud native 、 Platforms and projects . The content in this panorama is very rich , And with the development of the industry, it is becoming richer and stronger .

Panorama of cloud native technology

This huge technical system , It is mainly divided into seven technical sections , There are six important technologies that deserve attention ：

Microservices ： Microservices advocate breaking applications into parts , Loose decoupling will be applied , Realize the independent development and deployment of various functions , Improve the flexibility of application architecture , Improve the response speed to the business .

Containers ： Container is a lightweight virtualization technology , It is essentially a series of processes separated from the rest of the system . Containerization provides implementation guarantee for microservices , Play the role of application isolation , Application deployment can be simplified through containers 、 Manage and deliver . At present each big IT Manufacturers have invested a lot of resources in the research and development of container products and services , It is foreseeable that containers will be the main means of delivery in the future .

No server architecture ：“ There is no server ” It doesn't mean that servers are no longer needed in the future , Instead of focusing on the underlying service architecture , Developers only need to focus on the implementation of business logic that is more relevant to the business , For example, some code snippets of functions , The platform automatically deploys and starts on demand according to the load , And the need to automatically scale developers' business processing .

Service Grid ： Service grid can be regarded as more intelligent agent software . Based on containers and microservices , Through the service grid, users can manage the communication between services more finely and intelligently .

cloud ： The cloud is a network that provides resources , Is the foundation of cloud native technology , Everything in the cloud is built on the cloud . Establishing a correct understanding of the cloud is critical to understanding cloud primitives . For non-technical people , At least understand the many different service models of the cloud , And the application scenarios and architectures of different models .

DevOps：DevOps The word comes from Development and Operations The combination of , Emphasize the communication and cooperation between software developers and operation and maintenance personnel , By automating processes to make software build 、 test 、 Release faster 、 Frequent and reliable .

These six technologies are not independent of each other , It's interconnected .

The connection of six technologies

Cloud is the foundation of other technologies , The cloud provides computing for the operation of upper layer applications 、 The Internet 、 Storage and other technical architecture resources . Containers are located between the cloud infrastructure and Applications , Decoupled application and infrastructure resources . At the application level , Users can choose micro service architecture or non service architecture according to the scenario . In a complex architecture scenario , The communication of service components can be controlled through the service grid , Finally through DevOps Build a positive cycle of continuous iterative updating of application architecture .

The powerful advantages of cloud Nativity

What benefits can cloud primordial bring us ？

Application development team ： For the application development team , Cloud native can greatly reduce the cost of development and operation and maintenance , Improve the efficiency of application development 、 Improve the quality of application delivery . For example, through container technology , Development teams can more easily access the environment and resources needed for development , The developed applications can be more easily deployed and managed by the operation and maintenance team . adopt DevOps Best practices , The speed and quality of application delivery can be effectively improved . Cloud native technology improves the efficiency of application development and delivery , Reduce the time required for the application to go online , So that the development and business team members can have more time and energy for business innovation , It can effectively improve the innovation ability of the business , So as to enhance the competitiveness of enterprises in the market .

Customer ： For customers , The benefits of cloud native are ： The requirements submitted by customers can be responded to and realized more quickly , This is because cloud native technology can effectively shorten the application delivery cycle , Make requirements code faster , Code becomes an online application faster , Serve the end user , Realize the value of . In addition, cloud native greatly improves the user experience due to its ability of elastic expansion , Meet the rich needs of different businesses . For example, containers can help reduce application downtime , Enhance user experience .

The development status of cloud primitives

In recent years, , Yunyuan's production industry maintains a strong development trend , The concept of cloud Nativity has been recognized by the community 、 Widely recognized by enterprises and the market . Some popular cloud native technologies have been practiced in many industries and fields , Including the Internet 、 Finance 、 Manufacturing, etc. . In the context of this technological change , Digital China will also seize new opportunities , Upgrade technology strategy . at present , Digital China strives to build cloud based products , Improve technical and service capabilities , Strengthen the competitiveness in the cloud native field .
