Micro-Services CI/CD: Simplifying Software Delivery
In recent years, the adoption of micro-services architecture and container technology has led to a growing interest in continuous integration and continuous delivery (CI/CD) concepts. More and more companies are turning to continuous integration systems to address the quality issues caused by frequent releases. By automating the deployment of code using continuous delivery tools, software development teams can ensure that their applications are released reliably and efficiently.
Continuous Delivery: A Fast and Automated Approach
Continuous Delivery (CD) is a software engineering approach that enables development teams to generate source code from software release versions quickly, automatically, and repeatedly. This ensures that software can be released at any time, focusing on providing applications to end-users in a timely manner. With the widespread adoption of cloud services and micro-native architecture, the need for continuous delivery tools and practices has grown significantly.
The Benefits of Micro-Services
Micro-services bring numerous advantages, including:
- Complex business logic is split into smaller, independent services, each written in a cohesive and maintainable way.
- Development efficiency is improved due to the clear boundaries between services.
- Each micro-service can be deployed independently, enabling continuous deployment.
- Fault tolerance is increased, as a single service failure does not bring down the entire system.
However, the growing number of micro-services systems requires significant coordination work to integrate and deploy them synchronously, making sustained delivery complicated. To address this issue, container technology is used to solve the problem.
Container Technology: A Solution for Micro-Services
Container technology enables developers to package a micro-service in a container, which can be developed, tested, and deployed in an isolated environment. This simplifies the software delivery process, as operation and maintenance personnel can directly use the container for deployment and testing.
Continuous Integration: A Crucial Component
Continuous Integration (CI) is a fundamental concept that cannot be separated from Continuous Delivery. CI is the process of integrating code frequently, verifying the integration through automated builds, and running unit tests to find integration errors as quickly as possible.
The Basic Idea of Continuous Integration
The basic idea of CI is to use an automated process to monitor changes in the source repository. When changes are pushed to the warehouse, the process is triggered, downloading a copy, building, deploying, and running unit tests related to publishing.
Challenges in Continuous Integration
As business traffic and user growth increase, the number of users continues to grow, making it difficult to solve remodeling, adding new features, and system testing requirements using traditional test teams. Continuous integration becomes complicated, causing problems such as:
- The delivery period becomes shorter, and automated testing development cannot keep up with the speed of delivery.
- Multiple services are developed simultaneously, increasing the time-consuming process of FBISelf-test and reliance on parties.
- The number of service links increases, making the whole environment difficult to build.
- People share an environment, affecting each other and easily affecting test results.
- The number of warehouses increases, making the work of CI explosive.
Solving the Challenges with Micro-Services and CI
By using a micro-system service framework and continuous integration, teams can build automation and continuous integration platforms for process standardization. This enables continuous integration services to provide strong infrastructure support for micro-architecture, taking advantage of micro-services.
Implementing CI/CD in Micro-Services
Many teams have shared their plans to create a micro-services practice continuous integration tool chain. Each team has faced its own problems and designed different continuous integration schemes based on specific issues. Although the options are different, common experiences have played a significant role in the spread of CI/CD practices.
A Real-World Example: Using Tars and Jenkins
In China, a source of revenue at the meeting this weekend, Yuhui Tao, head of the group, will share how to use the micro-services framework Tars in combination with the CI/CD system Jenkins for continuous integration and build development and testing environments. This is a rare opportunity to welcome participation and learn from the experience of experts and users.
