一、The original intention of DevOps
In traditional organizations, the development department and the operations department are opposed to each other. The original intention of the birth of DevOps is a working method and culture that improves business value through the close cooperation between Dev (development) and Ops (operations). Teams can adopt tools such as continuous integration/continuous deployment to automate code building and application deployment, and continuously improve the efficiency and quality of software development through rapid feedback in the R & D process.
DevOps is a software development and operations methodology, aiming to accelerate the development and deployment speed of software applications and improve the quality and reliability of applications through close collaboration, automation, and continuous delivery. DevOps closely integrates the two links of software development and operations, enabling development and operations teams to work more efficiently and collaboratively, thus shortening the software development cycle and improving the quality and reliability of software.
The practices of DevOps involve multiple aspects, including:
Automated testing and deployment: By means of automated testing and deployment and other technical means, minimize the manual operations in the software development and operations process, and improve work efficiency and productivity.
Continuous integration and delivery: Closely integrate different links in the software development and operations process to achieve continuous integration and continuous delivery, accelerate the software delivery speed, and improve software quality.
Monitoring and log management: Through means such as real-time monitoring and log management, promptly discover and solve problems in software applications, and improve the reliability and stability of software.
Cross-functional cooperation: Encourage close cooperation between development and operations teams, jointly responsible for the development, testing, deployment, and operations of software applications, and improve the work efficiency and productivity of the team.
二、Challenges faced by DevOps at this stage
Frequent software delivery: Under the traditional software development and operation and maintenance model, the software delivery cycle is relatively long, requiring manual operations in multiple links, which is prone to quality problems and delayed delivery.
Problems to be solved
DevOps accelerates the software delivery speed and reduces the delivery risk through technical means such as automation and continuous delivery.
Software quality issues: Under the traditional software development and operation and maintenance model, due to the lack of collaboration and communication between the development and operation and maintenance teams, it is often difficult to guarantee software quality.
Problems to be solved
DevOps encourages close collaboration between the development and operation and maintenance teams, and jointly takes responsibility for the development, testing, deployment, operation and maintenance of software applications, thereby improving software quality.
Deployment and operation and maintenance complexity: Under the traditional software development and operation and maintenance model, deployment and operation and maintenance often require a large number of manual operations and complex configuration processes, which are prone to configuration errors and failures.
Problems to be solved
DevOps simplifies the deployment and operation and maintenance process and reduces the failure risk through technical means such as automation and continuous integration.
Lack of monitoring and feedback mechanism: Under the traditional software development and operation and maintenance model, there is a lack of real-time monitoring and feedback mechanism, and problems are likely to be discovered late, causing losses.
Problems to be solved
DevOps can promptly discover and solve problems in software applications through means such as real-time monitoring and log management, improving the reliability and stability of software.
三、DevOps pipeline
3.1 PLAN
The work included in this phase is as follows:
Determine business requirements: By communicating with the business side, determine the business requirements and goals of the software application, clarify the scope and priority of requirements, and provide guidance for subsequent development and testing work.
Develop a development plan: Based on business requirements and priorities, develop a software development plan and schedule, determine the development cycle and milestones, and formulate plans and strategies for the development phase.
Develop a testing plan: Based on the development plan and scope of requirements, develop a software testing plan and schedule, determine the plans and strategies for the testing phase, including test case design, automated testing, and the setup of the testing environment.
Determine the deployment plan: Based on the development and test results, develop a software deployment plan and schedule, determine the plans and strategies for the deployment phase, including environment configuration, deployment processes, and automated deployment.
Develop an operation and maintenance plan: Based on the deployment plan and business requirements, develop a software operation and maintenance plan and schedule, determine the plans and strategies for the operation and maintenance phase, including monitoring, log management, disaster recovery, and backup.
Manage changes and risks: In the Plan phase, the DevOps team needs to assess and manage various changes and risks, develop change management and risk management strategies, and ensure the stability and reliability of the software development and operation and maintenance processes.
3.2 CODE
The main work content at this stage
- Write code: According to the development plan and requirements specification, write code and conduct code management to ensure the quality and maintainability of the code.
- Conduct code review: During the development process, conduct code review to ensure that the code complies with best practices and specifications and reduces potential code defects.
3.3 BUILD
The main work content of this stage
In the BUILD phase of DevOps, the development team needs to automate tasks such as code compilation, static code analysis, and code packaging, and conduct automated testing and continuous integration to ensure the quality and reliability of the software package. Automating these tasks can reduce human errors and improve the efficiency and reliability of the software development and operation and maintenance processes.
3.4 TEST
The main work content of this stage
- Carry out automated testing: In the TEST phase, conduct automated testing, including unit testing, integration testing, system testing, and acceptance testing, etc., to verify the quality and stability of the software package.
- Carry out continuous integration: In the TEST phase, conduct continuous integration, integrate different code branches together to ensure the consistency and stability of the software.
- Carry out performance testing: In the TEST phase, conduct performance testing, detect the performance of the software package under different loads to ensure the scalability and reliability of the software package.
- Carry out security testing: In the TEST phase, conduct security testing, detect vulnerabilities and security risks in the software package to ensure the security and reliability of the software package.
- Carry out user experience testing: In the TEST phase, conduct user experience testing, detect the ease of use and user satisfaction of the software package to ensure an excellent user experience of the software package.
3.5 RELEASE 和DEPLOY
In DevOps, Release and Deploy are the last two crucial phases in the software development and operation process. After completing testing and verification in the testing phase, they are the phases of deploying the software package to the production environment and providing services to users.
3.6 OPERATE 和MONTORING
In DevOps, OPERATE and MONITORING are two inseparable phases, and both are very important components in the software development and operation and maintenance process.
The OPERATE phase refers to the stage after software deployment, ensuring that the software runs stably in the production environment and provides services to users. In this stage, the team needs to carry out tasks such as monitoring the production environment, capacity planning and management, log management and analysis, security management, and formulating fault tolerance and recovery strategies to ensure the reliability and stability of the software in the production environment.
The MONITORING phase refers to the stage of real-time monitoring and management of the production environment. In this stage, the team needs to use various monitoring tools and technologies to conduct real-time monitoring of the production environment, collect and analyze performance data, log data, metric data, etc. of the system and applications, and promptly detect and handle failures and problems to ensure the reliability and stability of the production environment.
Google Cloud Reference Solution
The next process is a DevOps reference process for cloud migration on Google Cloud.
When the developer completes the development and submits the code to [Cloud Source Repositories], this will trigger the webhook, and [Cloud Build] will be called for building and testing. If the test fails, the developer will be notified to conduct debugging. If the test passes, the built artifacts will be pushed to [Artifact Registry], and finally, [Google Kubernetes Engine] will be used for deployment.
