In this article, I would like to introduce tools for DevOps. Currently, there are quite a variety of tools available for use. First, let’s see what DevOps is and its importance in today’s system development.
DevOps is a concept to make software development more efficient. The principle of DevOps is collaboration between the Dev team (Development) and the Ops team (Operations).
The development team is responsible for developing software to meet requirements of customers, including testing before delivery to the customers. The operations team is responsible for managing servers in system installation as well as monitoring the system after it has been delivered to the customers.
DevOps is a methodology that helps both teams work together seamlessly and systematically by applying processes and tools to integrate the work of the development team and the operations team. It also improves the quality and stability of the developed software and reduces conflicts in the collaboration of both teams.
The following samples are tools to implement DevOps.
Build Tools
I would like to introduce a build tool called Apache Maven. This tool is used for managing the libraries of the system, building applications, and packaging code and resources into .jar, .war, and .ear files to be ready for deployment. Software developers can manage libraries and versioning for builds through XML file configuration (Pom.xml). In addition, Libraries are also regularly updated on Maven’s website https://mvnrepository.com/ . For more details, you can study from the following link. https://maven.apache.org
ReleaseTools
Jenkins is a server-based application used for automatic application deployment.
When developers commit their codes to the specified repository, Jenkins will connect to the developers’ repository to build and deploy the application automatically to the server. In case it fails to build, a notification will be shown on the Jenkins system. This can help developers reduce errors that may occur in manual application deployment.
In addition, Jenkins also supports many platforms, such as Windows, Mac, and Linux. You can click the following link for more details. https://www.jenkins.io/
MonitoringTools
Grafana is an open-source dashboard tool that allows users to monitor their application performance in real time. It also provides notification in case there is a problem while monitoring.
Samples of using Grafana
- Using for monitoring system testing. By connecting to JMeter (a tool for system testing), the test result will be shown on Grafana’s dashboard.
- Using for monitoring server. In case the server has a problem, you can connect to Grafana to monitor the server status.

In addition to the above-mentioned tools, there are many other tools used in DevOps. You can study more from various articles on the Internet. Anyway, it is more important to understand the working principles and collaboration process between the development team and the operation team than the tools you use, and then use these tools to produce quality output that meets your goals.
