This article mainly shows you "what is the origin of the cloud", the content is easy to understand, clear, hope to help you solve your doubts, the following let the editor lead you to study and learn this article "what is the origin of the cloud?"

The concept of Cloud Native

What is cloud origin? For this problem, we need to understand that cloud nativism does not refer to a specific technology, but a collection of technical systems, concepts and system design principles. For example, the micro-service architecture, Kubernetes container orchestration, Devops and so on that we often discuss are all components of the cloud native system.

From this point of view, for companies that have implemented cloud service deployment, Spring Cloud micro-service architecture, Kubernetes containerization deployment, and built an automated publishing system, they are actually implementing the concept of cloud native architecture. So, do you think many companies are already implementing cloud native architecture?

According to the official description of CNCF (Cloud Native Computing Foundation), cloud native technology refers to the technology system that facilitates the elastic and scalable deployment of applications in new dynamic environments such as public cloud, private cloud or hybrid cloud. The representative technologies of cloud native mainly include container, service grid, micro-service, immutable infrastructure and declarative API. Using these technologies, we can build a loosely coupled system that is more fault-tolerant and easier to manage and observe, coupled with some reliable automation technology and a complete monitoring and early warning system. Cloud native technology will enable developers to iterate and deliver software systems more quickly and easily.

Therefore, from the above description, cloud native technology is actually not a concept that suddenly became popular, but an abstract summary of system architecture concepts and design principles gradually recognized by the industry with the popularity of distributed application architecture technologies such as cloud computing, micro-service architecture, service grid and other distributed application architecture technologies, and driven by containerization technologies represented by Docker and Kubernetes.

Cloud native technology map

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

As shown above, you will find that the so-called cloud native is a hodgepodge of technologies, covering almost most of the popular back-end technologies, and even extending to areas such as AI, machine learning, edge computing, and so on. However, in terms of practical application scenarios, the main features of cloud native architecture are still reflected in the cloud environment, micro-service architecture, service grid, Devops automated delivery, containerized deployment.

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

On the other hand, the micro-service-oriented architecture can split the original single system with high coupling into atomic systems based on the boundary of independent business capability on the premise of following the software design principle of "high cohesion and low coupling". The advantage of this is that each subsystem can be delivered and deployed independently, thus achieving more agile software iteration results. At present, the micro-service technology represented by Spring Cloud has almost become the de facto software construction standard, while the next-generation service grid technology represented by Istio and Linkerd is also developing rapidly, all of which effectively pave the way for the popularization of cloud native architecture.

In addition, the containerized orchestration technology based on Kubernetes has in fact become a standard infrastructure environment for micro-service operation, and it is the popularity of Kubernetes that really promotes the popularity of cloud native architecture. Kubernetes can be said to be the core hosting platform of cloud native architecture. There are also some articles about the basic principles and practice of Kubernetes for reference in this column, which can be read by interested friends.

The above is all the content of this article "what is the origin of the cloud?" Thank you for reading! I believe we all have a certain understanding, hope to share the content to help you, if you want to learn more knowledge, welcome to follow the industry information channel!
