Cloud Native is a hot term in the technology circle recently. I believe you have heard of it more or less. However, for most casual developers, the term “cloud native” is still somewhat unfamiliar, so much so that when you first hear it, you might ask, “What is this technology, and have I used it?” Questions like that.

This is not surprising, as for most of the average developer, we spend most of our time developing business code on infrastructure built by someone else, and pay little attention to the infrastructure environment on which our business applications run, but this is exactly what building cloud-native apps is all about. In today’s article, we will talk about the topic of cloud native!

The concept of cloud native

What is cloud native? It is important to understand that cloud native is not a specific technology, but rather a collection of technical architecture, concepts, and system design principles. Things like microservices architecture, Kubernetes container choreography, Devops, etc. are all part of cloud native architecture.

From this perspective, companies that have implemented Cloud service deployment, Spring Cloud microservice architecture, Kubernetes container deployment, and built a set of automated distribution systems are actually practicing the concept of Cloud native architecture. So, do you think a lot of companies are actually implementing cloud native architectures?

According to the official description of CNCF(Cloud Native Computing Foundation), cloud native technology refers to the technology system that facilitates the flexible deployment of applications in the new dynamic environment such as public cloud, private cloud or hybrid cloud. Cloud native technologies mainly include containers, service grids, microservices, immutable infrastructure and declarative apis. These technologies can be used to build loose-coupled systems that are more fault tolerant, easier to manage and observe. Coupled with some reliable automation technologies and complete monitoring and warning systems, cloud native technologies will enable developers to iterate and deliver software systems more quickly and easily.

Therefore, it can be seen from the above description that cloud native technology is not a suddenly popular concept, but with the popularization and popularity of distributed application architecture technologies such as cloud computing, microservice architecture and service grid, as well as the promotion of container technology represented by Docker and Kubernetes, An abstract summary of system architecture concepts and design principles gradually accepted by the industry.

Cloud native technology atlas

Here I summarize a technical map of cloud native architecture for your reference, as shown in the figure below:

As you can see, so-called cloud native is a hodgepodge of technologies that includes most of the popular back-end technologies, and even extends to AREAS like AI, machine learning, and edge computing. However, from the perspective of practical application scenarios, the main features of cloud native architecture are reflected in cloud environment, micro-service architecture, service grid, Automatic Devops delivery and containerized deployment.

The cloud environment is about using cloud servers, which for most companies means using public cloud services to deploy applications, rather than maintaining a complex server room of their own. The advantage of this approach is that it can greatly reduce the operation and maintenance cost and improve the service stability by taking advantage of the flexibility and distribution of cloud services.

Microservices-oriented architecture, on the premise of following the software design principle of “high cohesion, low coupling”, can split the original highly coupled monomer system into atomic systems with independent business capabilities as the boundary. The advantage of this is that each subsystem can be delivered and deployed independently, enabling more agile software iterations. At present, the microservice technology represented by Spring Cloud has almost become the de facto standard for software construction. The next generation of service grid technologies represented by Istio and Linkerd are also developing rapidly, which effectively pave the way for the popularization of the concept of cloud native architecture.

In terms of Devops, it emphasizes to build an efficient and complete CI/CD process from a development operation perspective, and to manage the software life cycle through automated build tools and distribution systems. This allows the average developer to deliver more stable software code faster and more frequently.

conclusion

The above content gives you an overview of the concept of cloud native and summarizes the mainstream technology stack spectrum involved in cloud native. From the macro point of view, Cloud native architecture is a very huge system, which can almost contain all aspects of the current software back-end technology field. However, from the detail point of view, it is more or less accessible to our current work, such as Spring Cloud microservice, service fuse limiting, Kubernetes container choreographer and so on.

So in a way, cloud native is both abstract and concrete. It is not a specific product, but a set of technology system and methodology. With the further development of various open source technologies surrounding cloud native architecture, cloud native technology system will definitely become the mainstream, and then affect every technician, every enterprise and industry.
