This article mainly explains "how to correctly use DevOps in the enterprise". The content in the article is simple and clear, and it is easy to learn and understand. Please follow the editor's train of thought to study and learn "how to use DevOps correctly in the enterprise".

What is DevOps?

As the name implies, Devops is the abbreviation of "development" and "operation and maintenance". It defines a set of processes that bring about a cultural shift in the organization through collaboration between the development and operations teams. It contains four key components: collaboration, practice, culture and tools.

Second, why do we need DevOps?

DevOps brings a higher level of collaboration and speed, enabling organizations to increase productivity and reduce operating costs to effectively serve customers and maintain market competitiveness. It also helps to release products faster, manage unplanned work, and capture and resolve key issues more quickly.

III. DevOps practice

The independent devops team DevOps uses various tools, such as docker, K8s, Jenkins,Terraform,Nagios,Grafana,Prometheus, or Splunk, and the organization should establish a centralized department to create and operate these tools. This centralized management department is responsible for setting up agile practices in the development team, which will study new tools and stick to them, and provide mentoring procedures and training to implement DevOps. The core work of this department is to pursue the automation of testing, integration and deployment, reduce personnel participation, reduce communication costs, and bridge the gap between technical teams.

Continuous integration (CI)

CI is a software development practice that improves collaboration between teams and helps build high-quality software. The development team periodically checks in code changes in the repository, and CI performs automatic builds and tests to verify code quality. The practices used in continuous integration can quickly detect the challenges of the software development life cycle (SDLC) in the early stages, thus helping the development team solve the problem itself during the development phase.

Continuous delivery / deployment (CD)

The deployment process has different stages, such as developing →, building →, verifying → build version control, → deployment, → deployment, and so on. The idea of a continuous deployment process is to automatically deploy the developed code to a production environment after building all the stages that have passed the QA phase. -beta,Integration,UAT et al. There are tools available, such as Spinnaker,Jenkins,Harness,Ansible,Chef,Puppet, that allow DevOps teams to build automated pipelines that can be deployed in multiple environments with minimal human intervention.

Continuous delivery is a practice of DevOps, where the new code base is tested by the QA team at different stages of the automatic and manual QA cycle. If the code base passes the QA cycle and is approved by the QA team, it will be deployed to a production environment. In this way, DevOps divides the team into shorter cycles, enabling the team to build, test, and release the code base faster and more frequently. This enables organizations to provide more versions, reduce manual deployment, and minimize the risk of failure in production.

Configuration Management (CM)

Configuration and change management are important components of the DevOps cycle. Configuration management is the automation of configuring, monitoring, managing, and maintaining all entities of infrastructure and systems, such as servers, applications, storage, networks, and all managed services. There are also many centralized configuration management tools available, such as nacos, apollo and so on.

Configuration management brings many advantages, such as simplifying the setup of the new environment, reducing the risk of production configuration, and saving a lot of time in software development. without having to spend time and effort using infrastructure, that is, code practices, to start new services from scratch.

Change management

Change management is a process of requesting, planning, implementing, and evaluating changes needed to meet new requirements. During the configuration management process, if any changes are needed in the existing system and infrastructure, change management should be considered at this time. The operations team needs to provide their comments, the reasons for the changes, and possible consequences on a larger scale, including other systems that may be affected by the new changes.

Test automation

Automated testing for each code base helps you run more tests, increase test frequency, and save time on manual QA. This process can detect errors early, fix them, and improve the overall software quality. There are several tools that can be integrated with DevOps tools, such as Selenium,RobotFramework,Appium,XCUITest,JUnit, for automated testing.

Continuous monitoring (CM)

Continuous monitoring recommends the use of several tools, dashboards and alerts to monitor all systems and infrastructure, including real-time insight into different metrics that affect the software, such as system performance, number of tests, success and failure rates, deployment status, error logs and all information is displayed in graphical, tabular and detailed report formats. To accomplish such monitoring, the DevOps team can set up tools, such as Prometheus,Grafana,Nagios,Appdynamics,NewRelic,Splunk,Logstash, as well as more tools available on the market.
