The current development of cloud computing technology is unstoppable, and cloud native has become a highlight in this technological change. Cloud native is an emerging software development and deployment model. It aims to use modern technologies such as cloud computing, containerization, and microservices to improve the efficiency, elasticity, reliability, and maintainability of software development and deployment, thereby better Meet the needs of enterprises and users. This article will provide a detailed introduction to the concepts, characteristics, architecture, technology stack, application scenarios, etc. of cloud native.
1. Definition and characteristics of cloud native
1. Containerization: Cloud native applications usually use container technology (such as Docker). Deployment and management. Containerization can improve application portability, elasticity, and scalability, allowing applications to be deployed, updated, and rolled back faster.
2. Microservices: Cloud native applications usually adopt a microservice architecture, splitting a large application into multiple small services, each service can be independent Deploy, scale, and manage to improve application reliability and maintainability.
3. Automation: Cloud-native applications often use automation tools (such as Kubernetes) for deployment, scaling, monitoring, and troubleshooting. Automation can improve application efficiency and stability while reducing human error.
4. Cloud native technology stack:Cloud native applications usually use a series of technology stacks, including containerization, microservices, automation, cloud native databases, cloud native networks, etc. . These technology stacks can provide a better cloud-native development and deployment experience, thereby accelerating application development and launch.
5. Cloud native culture:Cloud native also includes a new culture and way of thinking, namely DevOps. DevOps emphasizes close collaboration and communication between development and operation and maintenance to better realize the automation and continuity of software development and deployment.
Summary: Cloud native is a new software development and deployment model. Cloud native applications usually use container technology to deploy and manage, split into multiple small services, and use automated tools for deployment, expansion, monitoring and fault handling. And adopts cloud native technology stack to provide better development and deployment experience. At the same time, cloud native also emphasizes close collaboration and communication between development and operation and maintenance to achieve automation and continuity of software development and deployment.
2. The difference between cloud native applications and traditional applications:

3. Cloud native architecture
The architecture of cloud native applications usually includes the following components:
1. Containerization platform:Containerization platform (such as Kubernetes) is used to manage and deploy containerized applications, including container orchestration, automated expansion, load balancing, service discovery, etc. Function.
2. Microservices: Microservices are the basic building blocks of cloud native applications. They can be deployed, scaled and managed independently. Microservices communicate with each other through APIs and can be flexibly combined and split to achieve rapid iteration and update of applications.
3. Cloud native database: Cloud native database (such as CockroachDB) is a distributed, highly available, scalable database system that can meet the storage requirements of cloud native applications. need.
4. Cloud native network: Cloud native network (such as Calico) is a network virtualization technology that can provide high performance, high reliability, and elasticity for cloud native applications. and secure network services.
5. Cloud native security: Cloud native security (such as Falco) is a container-based security monitoring system that can monitor security events inside the container in real time, so as to promptly discover and Address potential security threats.
4. Cloud native technology stack
The technology stack of cloud native applications usually includes the following aspects:
1. Containerization technology:Containerization technology (such as Docker) is the cornerstone of cloud native applications. It can package applications and their dependent operating environments into a reliably Portable container images for rapid deployment and migration.
2. Container orchestration:Container orchestration tools (such as Kubernetes) can automatically deploy, scale, manage and monitor containerized applications. Container orchestration can improve application resiliency and reliability while reducing operational burden.
3. Microservice architecture:Microservice architecture can split a large application into multiple small services, each service can be independently deployed, expanded and managed . Microservices can improve application reliability, maintainability, and scalability.
4. Automation tools: Automation tools (such as Jenkins, GitLab CI/CD) can realize automated building, testing, deployment and monitoring of applications. Automation can improve application efficiency and stability while reducing human error.
5. Cloud native database: Cloud native database (such as CockroachDB) is a distributed, highly available, scalable database system that can meet the storage needs of cloud native applications. need.
5. Cloud native application scenarios
Cloud native applications can be used in various scenarios, including:
1. Internet applications: Internet applications usually have the characteristics of high concurrency, high reliability, and rapid iteration, and are suitable for development and deployment using cloud native technology.
2. Internet of Things applications: Internet of Things applications are usually distributed, large-scale, heterogeneous, etc., and are suitable for development and deployment using cloud native technology.
3. Financial applications:Financial applications usually require high reliability, high security, high scalability and other characteristics, and are suitable for development and deployment using cloud native technology.
4. Enterprise-level applications:Enterprise-level applications usually require high reliability, rapid iteration, flexibility and other characteristics, and are suitable for development and deployment using cloud native technology.
