What are the benefits of applying cloud native?

A more detailed answer to this question: In early 2022, we conducted a survey on the application of cloud native technology. We surveyed hundreds of technicians from R&D, testing, operation and maintenance architecture and other different industries through online questionnaires. They came from enterprises of different sizes in different fields such as Internet, finance, manufacturing, energy and government departments, and generated relevant reports according to the survey results. By consulting the report, we can deeply understand the application, technical practice and difficulties of landing solutions of various industries in cloud native infrastructure, application architecture and other sectors, and observe cloud native from multiple angles.

What are the benefits of applying cloud native? This is an inherent advantage of the cloud:

First, the cloud creates a lightweight, fast and unchanging infrastructure.

In a cloud native environment, the supporting infrastructure is usually cloud container technology. The life cycle of the container is very short, mostly in seconds or minutes, and the resources occupied are much smaller than virtualization, so the biggest feature of the container is light and fast. Because containers are light and fast, in practical applications, applications are usually not installed or updated in containers, but more persistent images are updated, and the new images are downloaded and the corresponding containers are started through the scheduling system, and the old containers are deleted. This mode of updating the image without changing the container runtime is called invariant infrastructure. From the unchanging infrastructure, it can be seen that the cloud native operation is completely different from the traditional virtual machine operation mode.

Second, the cloud native landing micro-service architecture.

Traditional applications are usually single architecture and single application system, such as WebSphere, WebLogic or. Net framework. From the front end to the middleware to the back end, all components are generally deployed on the server in a centralized way. Later, with the introduction of Web service standards, applications were delivered by standard services, and applications interacted with each other through Remote Service Call (RPC), forming a service-oriented architecture, which greatly improved the standardization of application components and the efficiency of system integration. In the design of cloud native application, the application volume is smaller, so the function of traditional single application is disassembled into a large number of independent and fine-grained services. For an application, microservice is an application that can be published independently; For a team, it provides more ideas for cooperation and communication for various departments and different positions. These different ideas can provide more help for cloud native management and make cloud native do better.

Third, the cloud has achieved continuous integration and continuous deployment.

The core of continuous integration is the correct integration of newly submitted code and source code. Developers frequently submit code to the code warehouse for many times, and compile and verify the newly submitted content automatically (such as code format detection), and then merge it into the specified branch. This process not only ensures the integrity and security of the code.

Continuous deployment is a prominent feature of cloud nativity, because the whole process from the submission of code by developers to compilation, testing and deployment is automated, which speeds up delivery and shortens the time for finding problems and fixing them. However, CICD pays attention to the whole process from development to delivery, and the whole production chain needs intermediate testing, simulation and automatic deployment, and every step needs attention. This also reflects the importance of sustainable development and its indispensable position.

Fourth, the cloud has realized the integration of development and operation.

The integration of development and operation is a set of practices that combine software development with IT operation, aiming at shortening the software development cycle and providing continuous delivery of high-quality software. DevOps is not the same as agile development, but it is a useful supplement to agile development. Many DevOps development concepts (such as automatic build and test, continuous integration and continuous delivery) come from agile development. Different from agile development, DevOps is more about bridging the gap between development and operation and focusing on accelerating software deployment. At present, the business logic of many cloud native applications needs to be adjusted in time, the functions need to be enriched and improved quickly, the cloud software needs to be iterated quickly, and the cloud application needs to be deployed quickly after development, which makes the whole life cycle of cloud native more orderly and standardized.

Fifth, the birth of the cloud has brought the era of all-cloud development.

With the rapid popularization of cloud native technology, the era of all-cloud development has arrived, and the new ecological trend of cloud native industry is becoming more and more mature. Cloud Native brings enterprises a one-stop cloud solution covering cloud native development, testing, operation and maintenance, and observability, and realizes the shortest path for enterprises to realize digital transformation.
