With the development of mobile Internet, applets have become a very popular application method, which can run directly on mobile terminal devices (such as App, iPad, etc.) without installing any application. Microservice architecture is a kind of distributed system architecture, which can improve the scalability, flexibility and maintainability of the system.
This article will discuss their connection and application scenarios from the perspectives of small program container and microservice architecture.
1. Small program container
The applet container is a lightweight container technology. In short, it allows applets to run on the App. The applet container provides a way for developers to quickly build and publish applets. Some front-end technologies can be used to develop applets and deploy them into applet containers.
The emergence of small program containers provides developers with a new application method. It can translate some applications under the small program ecology on the market to mobile terminal devices, so as to realize one-end development and multi-terminal operation, which greatly reduces It lowers the development threshold for developers and plays a role in reducing costs and increasing efficiency. At the same time, some small program container manufacturers on the market, such as FinClip , are equipped with small program management background functions, which can also help enterprises to conveniently and one-stop manage (up and down shelves, review) small program applications. Through the open plug-in capability of the IDE, third-party plug-ins (such as: login, payment, push, etc.) on the market can be introduced in the form of SDK to provide better user experience and business value for enterprises and developers.
2. Microservice architecture
Microservice architecture is a distributed system architecture that splits a large application into multiple independent small services, each of which can be independently developed, tested, deployed, and expanded. The advantage of the microservice architecture is that it can improve the scalability, flexibility and maintainability of the system, and it can also improve the development efficiency and deployment speed.
The emergence of the microservice architecture is to solve various problems of monolithic applications, such as monolithic applications that are difficult to expand, maintain, and deploy. By splitting a monolithic application into multiple independent small services, application decoupling and functional reuse can be better achieved, and at the same time, different business scenarios and demand changes can be better dealt with.
3. The connection between small program container and microservice architecture
Small program containers and microservice architectures can be used in combination. For example, when developing small programs, you can use the microservice architecture to build back-end services, provide the data and functions required by the small programs, and then deploy these services to the cloud, through the network interface to interact. This method can realize the separation of the front and back ends of the applet, and improve the scalability and flexibility of the system.
Specifically, the microservice architecture can provide different functions and data services by splitting the back-end services into multiple independent small services, such as user management, payment, push, etc. These small services can be developed and deployed using different programming languages, frameworks and databases, and can be tested and deployed independently, enabling faster response to business needs and changes. By deploying these small services on the cloud, better elastic expansion and load balancing can be achieved, and the reliability and availability of the system can be improved.
The combination of small program container and microservice architecture can also realize the separation of front and back end, which is very valuable for developers. Front-end developers can focus on the interface design and interaction logic of the applet, while back-end developers can focus on service implementation and data processing, and the interface between the two interacts through the network. This approach can improve development efficiency and deployment speed, while also reducing application coupling and maintenance costs.
In the combination of small program container and microservice architecture, some common technologies and frameworks can also be used, such as Spring Boot, Node.js, Docker, etc. These technologies and frameworks can help developers build and deploy microservices faster, and can also provide some advanced functions, such as load balancing, service discovery, containerized deployment, etc.
4. Application scenarios of small program container and microservice architecture
The combination of small program container and microservice architecture is very valuable in many scenarios. Common application scenarios include: e-commerce, social networking, online education, healthcare, enterprise applications, etc. By using the microservice architecture, these functions can be split into multiple independent small services, and each service can be independently developed, tested, deployed and expanded. At the same time, the applet container can be used as a front-end application container to run existing WeChat applets on multiple terminal devices, providing a good user interface and interactive experience. This approach can improve the scalability and flexibility of e-commerce applications, while also improving development efficiency and deployment speed.
In addition to the above application scenarios, the combination of small program containers and microservice architecture can also be widely used in other fields, such as online games, smart home, smart transportation, etc. With the continuous development of Internet technology and Internet of Things technology, there will be more and more application scenarios for this combination.
V. Summary
The combination of small program containers and microservice architecture can help developers build and deploy microservices faster, improve system reliability and availability, achieve separation of front and back ends, and reduce application coupling and maintenance costs. The application scenarios of this combination are very extensive, involving many fields, such as e-commerce applications, social applications, online education applications, medical and health applications, enterprise applications, etc. With the continuous development of Internet technology and Internet of Things technology, this combination method will become more and more popular and become one of the mainstream methods for future application development.
